Summary of findings

This article reports on a Hungarian study of 76 male and 4 female regular participants (mean age: 35) in fitness activities and the psychological benefits of aerobic exercise.  Half the sample exercised on a stationary bicycle and half on a treadmill in their normal environment and at self-selected workloads. 

All participants completed the Exercise-Induced Feeling Inventory based on a series of Likert scales before and after 20 minutes of exercise and all wore a heart rate monitor. 

Distance travelled and weight-corrected calories burned were read directly from the equipment displays.  The exercise intensity and heart rate, perceived intensity and estimates of burned calories were higher in runners than cyclists.  However, there were no differences in self-reports of enjoyment of the exercise sessions and in the psychological improvements from pre- to post-exercise between the two groups.  The authors conclude that significant psychological improvements occur after a 20-minute bout of exercise and, in line with previous research, that these changes are independent of the workload or exercise intensity.

Summary of findings

This article reports on a Canadian short-term longitudinal study to examine the potential role of participation in organised sport to act as a moderator between shyness and psychosocial maladjustment in childhood. It was hypothesised that sports participation would have unique benefits for shy (and anxious) children in terms of their peer relationships, socioemotional functioning and general well-being. The research was undertaken with 201 schoolchildren (average age: 10; 52% female) using two survey points 12 months apart.

Parents completed a Social Skills Rating Scale; the children completed a Children’s Shyness Questionnaire, a Conflict Tactics Scale measuring physically aggressive behaviour over the previous six months, a self-report sports participation information sheet, a general well-being questionnaire, a self-description questionnaire, a Social Anxiety Scale, a Loneliness and Social Dissatisfaction measure and positive and negative affect schedule.

The authors’ analysis suggests that participation in organised sport was related to various positive psychosocial outcomes, with sports participants reporting more assertiveness, self-control, positive affect and well-being, physical ability self-esteem, physical appearance self-esteem and peer self-esteem than non-participants. Shy children who took part in organised sport had higher general self-esteem than did shy non-participants.

The authors suggest that this effect might reflect the importance of sport in determining social status.

Over the 12 month period shy children who took part in sport demonstrated a significant decrease in social anxiety. The authors list a number of limitations with their research: it relied largely on children’s self-report and recall (especially for sports participation), if failed to explore issues of aptitude and there was substantial attrition in the sample over the 12 months, with those who opted out being recorded as a being the least cooperative, least assertive and more social anxious at stage 1, which will have reduced the variability of outcomes at stage 2.

The authors conclude that sports participation can play a protective role against some of the negative outcomes associated with shyness.

Expand The moral worth of sport reconsidered: contributions of sport to life aspirations and psychological well-being

Authors

Keywords

Psychological well-being, sport, adults.

Country of research

United Kingdom

Summary of findings

This article reports on a study to test the hypothesis that the effects of participation in recreational and competitive sport on psychological well-being are mediated by the importance ratings of life aspirations. 

The article begins with an exposition of self-determination theory and a theoretical discussion of the importance of the basic psychological needs for experience of competence, autonomy and relatedness and their centrality to human development and growth and relationship with psychological well-being. 

They explore the distinction between hedonic enjoyment and eudemonia (personally expressive activities that facilitate self-realisation through the fulfilment of personal potentials).  The authors also explore the related concepts of intrinsic and extrinsic life aspirations and suggest that the relative importance of these is critical for psychological well-being. 

Further, not all forms of sports participation are associated with psychological well-being because they do not promote valuing and/or attainment of intrinsic life aspirations.  This is most obviously the case with competitive sport and its emphasis on extrinsic rewards. 

Within this context the authors seek to explore three hypotheses:

• While intrinsic aspirations would positively predict both hedonic and eudemonic happiness, attainment ratings of extrinsic aspirations would predict neither hedonic or eudemonic well-being;
• ndividuals who participate in competitive sport would assign greater importance to extrinsic aspirations relative to intrinsic aspirations compared to recreational participants;
• The effects of activity type on psychological well-being would be indirect via importance ratings of life aspirations.

The study was conducted on 83 male and 35 female university students (average age: 20.8 years).  Life aspirations were measured and their importance evaluated via 14 categories, including intrinsic life aspirations, meaningful relationships and health-related goals.  Extrinsic goals included financial success, fame and image.  A personal expressiveness scale was used to asses psychological well-being on hedonic (pleasure vs pain) and eudemonic (activities congruent with deeply held values) facets.  The type and level of current and previous physical activity were recorded. 

The authors claim that their findings indicate that, compared to recreational sport, competitive sport is associated with diminished psychological well-being when it is viewed as a means to achieve extrinsic life goals. 

Consequently the relative importance of intrinsic and extrinsic life aspirations is a key dimension in predicting psychological well-being.  Whereas attainment of intrinsic life aspiration through sport is associated with both hedonic enjoyment and eudemonia attainment of extrinsic aspirations was associated with neither. 

They conclude that the key factor determining the level and quality of psychological well-being is life aspirations rather than sports participation per se.  They suggest that the moral worth of sport does not lie so much in sport participation itself, or in the frequency of participation, but in the goals and values that people express though sports participation.

Country of research

Summary of findings

This longitudinal Canadian study explores the association of girls’ self-esteem with their achievement and self-evaluations on interest and competence in team sports. Following a review of relevant literature the authors conclude that previous research tended to ignore low-income female populations; fail to differentiate between individual and team sports and tend to be cross-sectional. It seeks to test two hypotheses:

1. Girls’ early adolescent team sports achievements will predict higher global self-esteem later in adolescence;
2. This association will be mediated by the girls’ team sports self-evaluations. Adolescent girls (n: 247) from racially and ethnically diverse backgrounds were surveyed as apart of a larger study investigating the development of poor urban youth.

The average age of the survey population at stage one was 13 years and 16 at the second stage. At each stage data were collected on self-esteem, team sports achievement (type of team, whether captain, if won an award), team sports self-evaluation of interest and competence (e.g. ‘compared to others, how good are you?’, ‘how much do you like playing team sports?’), individual sports self-evaluations of interest and competence.

The authors conclude that their data are consistent with the hypotheses that team sport achievement in early adolescence is related to girls’ global self-esteem in middle adolescence and that team sports self-evaluations mediate the relation between achievement and self-esteem. In contrast, the self-evaluations of individual sports failed to explain a significant proportion of the variance in global self-esteem.

The findings suggest that the associations of team sports achievement and team sports self-evaluations with global self-esteem may be due in part to the esteem–enhancing qualities of the team environment and are not entirely a function of sports’ participants higher rates of physical activity or a sense of general athletic competence. The authors also state that their findings support the view that domain-specific evaluations (in this case team sport) is the building blocks of global self-esteem.

However, the proportion of variance accounted for by team sports achievement and self-evaluations in global self-esteem were small.

The authors suggest that this small effect size may reflect the fact that a variety of experiences influences global self-esteem, or that the effects of team sport achievement may be vary, being moderated by team structure, team composition or team leadership qualities.

The authors suggest that sport for girls should address issues of the development of self-efficacy directly via such things as positive feedback, most valuable or improved player awards and creating roles of honour.

Keywords

Country of research

Summary of findings

This article reports on a 9-month controlled trail in the USA to explore the extent to which physical activity can promote increased physical self-concept and increased global self-concept among sedentary adolescent females (intervention groups: 61; comparison group: 59). 

The research sought to test  two hypotheses:

1. Participants would report increased physical self-concept in multiple domains and this would be accompanied by an increase in global self-concept
2. The enhancements in self-concept would be more pronounced among those intervention participants who increased their physical activity and/or their cardiovascular fitness (a measure ignored in most previous research). 

Before the trial commenced physical activity levels were self-reported on a 3-day (30 minute intervals) recall basis and these data were converted into metabolic equivalents.  During the trial period one weekday and two weekend days were assessed.  Cardiovascular fitness was obtained via a ramp-type progressive exercise test on a cycle ergometer, heart-rate monitors were used once per week and body mass index and body fat were recorded.  Data on physical self-concept were recorded on a 70 item Physical Self-Description Questionnaire. 

The intervention group met 5 days per week for 60 minutes each day (40 minutes activity time) for aerobic dance, yoga, basketball, swimming and Tae Bo.  In addition there was a once per week discussion on the benefits of physical activity.  The comparison groups did not have the discussion session and attended regular PE lessons. 

The study found that the intervention was not effective for enhancing physical self-concept (or global self-esteem), despite an increase in self-reported vigorous activity and a significant improvement in cardiovascular fitness. 

However, there was an interaction between improved cardiovascular fitness and enhanced global physical self-concept.  The authors hypothesise that, given the central role that body fat plays in adolescent females’ self-concept, the fact that the intervention was not intensive enough to  reduce this may explain the lack of impact on self-concept.  They also speculate that something more than simple participation in group-based physical activities might be needed to raise self-concept. 

The authors conclude that their study does not offer strong support for the hypothesis that increased physical activity leads to enhanced self-concept among sedentary adolescent females.  Rather, it appears that there may be a trend for enhanced physical self-concept over time, with increased fitness  accelerating this trend only in the context of an intervention that includes a didactic component informing participants why physical activity is important.  The authors suggest that their study raises new questions about the relative roles of cognitive and behavioural interventions.

Country of research

United Kingdom

Summary of findings

This provides an overview of the literature on the impact of exercise on self-esteem.

It examines the complex nature of self-esteem and the self-system and the role of the physical self within this. It explores the potential for exercise in the promotion of self-esteem and the various mechanisms through which this might be achieved. It reviews current research evidence on the effect of exercise on self-esteem and summarises the general conclusions to be drawn from cross-sectional research, intervention research (concentrating on 36 randomised controlled studies). It examines findings for various age groups and explores the characteristics of effective exercise, frequency, intensity and duration and outlines possible mechanisms underpinning the positive relationships between exercise and self-esteem (although these are not well understood).

Mechanisms may include: an undetermined psycho-physiological mechanism; improvements in fitness or weight loss; autonomy and personal control; sense of belonging and significance.

The general implications for practice are:

1. Greatest improvements in self-perception/self-esteem are likely to occur in those groups who have the most to gain physically from exercise participation, such as the middle-aged, the elderly and the overweight and obese.
2. Greatest improvements are likely to occur in those who are initially low in self-esteem, physical self-worth and body image, including women in general, those with mild depression, physically disabled children and adults, overweight and obese adults and, perhaps, offenders.
3. There is greatest support for the effectiveness of cardiovascular exercise and weight training programmes.
4. A focus on moderately demanding exercise, with sessions of about 60 minutes.
5. Programmes should last at least 12 weeks with some form of contact continuing for 6 months or more.
6. Adherence factors cannot be separated from those that promote self-esteem. Conditions that affect the attractiveness of the exercise programme, such as the qualities of the leader or the exercise setting, may be crucial to changes in self-esteem.

Country of research

Summary of findings

This is a systematic review of 14 randomised control trials of exercise programmes aimed at managing depression. These studies were selected from 72 similar studies based on rigorous methodological selection criteria and details of each study are provided. Despite this, all 14 studies had important methodological weaknesses; randomisation was inadequately concealed, intention to treat analysis was rarely undertaken and assessment of outcome was blinded in only two and follow-up periods were short. Participants in most studies were non-clinical, community volunteers and diagnosis was determined by their score on the Beck depression inventory. Studies indicate that aerobic and non-aerobic exercise have a similar effect. However, this may be because the effect is due to psychosocial factors, such as learning new skills or socialising, rather than the exercise itself. In the UK rates of compliance with exercise on prescription schemes vary from 20 percent to 50 percent. Consequently, the authors argue that it is reasonable to assume that compliance among patients with depression would be similar or worse and the widespread use of non-clinical samples suggests that any positive results may have limited generalisability. The authors conclude that it is not possible to determine from the available evidence the effectiveness of exercise on the management of depression. However, exercise may be effective in reducing the symptoms of depression in some volunteers in the short term. Doctors could recommend more physical activity to their motivated patients, but this should not replace standard treatment, particularly for those with severe disease. Exercise may be efficacious in reducing depressive symptoms, but the poor quality of much research is of concern.

Summary of findings

This article reports on a before-and-after study of 1,034 female participants (aged 8-13) in a 12 week twice-weekly developmentally focussed sports programme.  The research explored the impact of participation on self-esteem, body-size satisfaction, commitment to physical activity and risk behaviour.  The 12 week programme was structured around a series of topics relating to self-awareness, team-building and cooperation, community issues and media stereotypes.  Each session was structured around warm-up activities, stretching, multiple running activities involving a game to teach the session topic and a closing session to encourage individual and group behaviour. At the end of the 12 weeks all take part in a 5k running event.  A pre- and post-test self-completion questionnaire was used to collect the data.

Because of the non-experimental nature of the research the authors emphasise the preliminary and non-conclusive nature of the findings.  Nevertheless they conclude that participation in the programme resulted in beneficial changes in self-esteem, body-size satisfaction and physical activity commitment and frequency.  The two key findings are: (i) participation increased commitment to be physical activity, especially among the 11-15 age group; (ii) although improvements were greatest after the first exposure to the programme, those returning to the programme also experienced further improvements. The authors outline a number of threats to validity.  Although they conclude that some threats are minor, the issue of self-selection and a relatively low response rate (46%) are a possible concern and emphasise the preliminary nature of the findings.  The authors conclude that prior to initiating programmes to promote physical activity for girls it is important to consider structuring educational programmes which promote the development of self-esteem and positive attitudes toward physical activity in a fun atmosphere that does not stress exercise.

Summary of findings

This article reports on Australian research exploring the relationship between physical activity and health-related quality of life (HRQoL) and life satisfaction in women who participate in three forms of physical activity - club sport, gymnasium activities and walking.  Because of the social nature of participation in club sport, the researchers hypothesised that participants in sports clubs would have greater HRQoL than participants in the two other activities.

This was an observational study (n: 793 women) of the relationship between type, frequency and duration of physical activity plus measures of HRQoL and life satisfaction.  These data were compared with 2,345 women from a normative population sample.  Data were collected on the potential confounders of age, marital status, having children aged less than 16 years, and perceived financial stress.

After adjusting for the potential confounders, significant differences were found between the groups for six of the 36 measures on the HRQoL scale:  physical role functioning; general health; vitality; social functioning; emotional role functioning; mental health and the life satisfaction score.  In each case the club sport group had the highest mean score.  The differences between club and gymnasium groups were significant for all 8 variables, and between club and walk groups for 4 variables.

The authors admit that such a cross-sectional approach research cannot definitively establish a causal link, the results suggest that sport clubs are likely to enhance the health benefits of physical activity and support the notion that sports clubs might be beneficial settings for health promotion.  However, they conclude by suggesting that sports must develop strategies to overcome health and social barriers to participation.

Country of research

Canada

Summary of findings

This Canadian study explores the nature of the links between sports participation and self-esteem via a sample of 382 students (167 boys; 215 girls) in Grades 5-8 (ages 11-14) in four schools. The author provides a broad overview of the research on the nature of such relationships and adopts a hierarchical and multi-dimensional approach to the issues. In this, physical self-esteem is viewed as a potential mediator of the relationship between sports participation and general self-esteem. Further, physical self-esteem is divided into two components – physical appearance and physical competence – which may be differentially associated with boys and girls and have different impacts on global self-esteem. The issue of possible age-related changes to self-esteem are addressed by dividing the sample into younger adolescents (Grades 5 and 6) and older adolescents (Grades 7 and 8). 

A 70-item Physical Self-description Questionnaire was used to explore the multidimensional aspects of physical self-concept. A 23 item Body Esteem Scale was used to determine how positively individuals perceive themselves in terms of appearance and body image. A Sports Participation Information Sheet collected data on number of sports, years and level of participation.

No significant age-related differences in self-esteem were found. Girls felt less positively than boys in terms of physical competence and global physical self-esteem. However, girls and boys felt similarly satisfied about their physical appearance, with both reporting positive feelings about physical appearance and general self-esteem.  The benefits of sports participation were consistent for both sexes, making them feel better about themselves physically (appearance and competence) and generally. There was little difference between competitive and non-competitive sport. Consistent with previous research, the relationship between sports participation and general self-esteem was not direct, with participation having its strongest impact on physical self-esteem, which in turn was predictive of general self-esteem. Physical competence played a more significant role for boys in determining general self-esteem, with the more difficult to attain physical appearance more important for girls.

The authors list some limitations with the study: (i) it is cross-sectional and offers limited generalisability; (ii) it did not include other indices of domain-specific self-esteem which contribute to general self-esteem.

The authors conclude that sports participation can lead indirectly to improved self-esteem by impacting on domain-specific self-esteem which are closely related to physical self-attributes. The apparently direct link between physical appearance and general self-esteem for both boys and girls illustrates the strong social emphasis on physical appearance. They conclude that further research is needed into the impacts of types of sports participation, the level of sports participation and the frequency of regular physical activity.

Major events, psychological well-being

Country of research

United Kingdom

Summary of findings

This paper uses data on self-reported life satisfaction for 12 European countries to explore two hypotheses:

• The success of a nation’s athletes produces a measurable increase in reported happiness among citizens of that nation;

• Simply acting as host produces an increase in happiness among the citizens of a host nation.

The events chosen were Olympic Games, FIFA World Cup and the UEFA European Championships.

The authors provide a review of the literature and evidence on the economic impact of sporting events and on happiness.  They review the literature of the impact of events on employment and wages pointing out that jobs created are off-set by jobs lost due to substitution effects and that the multiplier for sports related expenditure may be lower than for other types of expenditure and long term employment might be part-time, casual, low skilled and low waged.  The review material related to sports stadia and legacy, estimating tourist numbers – time switchers, causal, crowding out – and infrastructure investments and urban regeneration.  As many of the economic arguments are weak the authors suggest that stronger justification for public expenditure in events might lie in the economics of happiness.  They provide a brief overview of the strengths and weaknesses of research on the extent of happiness in populations and the various factors which have been explored.  They propose that their work contributed to this emerging branch of economics by focussing on the relationships between sporting events and population happiness.

The authors use life satisfaction data for 12 countries from the Eurobarometer Survey series between 1974 and 2004.  For the Olympics they focus on measures that relate expected performance to actual performance and for the hosting hypothesis they include a dummy variable for the host.  For football tournaments they used FIFA rankings before and after tournaments.

The results indicate that reported life satisfaction is positively affected when national athletic performance is better than expected, but the effect is not significant except where performance is measured relative to lagged medals (an adaptive expectations approach to Olympic performance).  Overall they conclude that it is plausible that national sporting success can lead to an increased sense of life satisfaction, but the effect is not a very powerful one.  With regard to the impact of hosting events there is a stronger effect, at least relating to soccer tournaments – it seems that it is not the performance at an event, but hosting the event that matters for happiness.

However, they conclude that overall the results do not generally support the view that there are systematically significant and positive anticipatory or post event legacy effects with respect to measured happiness. The authors argue that the data indicate that hosting events does not create more than a short-term feelgood factor.

Country of research

Summary of findings

This is a systematic review of literature and research relating to a variety of aspects of amputees’ participation in sports: biomechanics, cardiopulmonary function, psychological aspects, sports participation and physical functioning and sports injuries.  Following an extensive search of databases the authors identified 3,689 papers, of which only 47 (1.3%) met their specific criteria.  All papers are listed providing the details of methods, amputee characteristics, study design and results.  Most were older than 10 years and had cross-sectional designs.  Study participants were generally younger and often had more traumatic amputations than the general population of individuals with limb amputations.  The heterogeneity of population characteristics, intervention types and main outcomes made pooling of data impossible.  The findings are accompanied by advice about the implementation of exercise and sports programmes.

Participation in a variety of relevant sports (related to individual capabilities) and physical activity was found to positively influence physical fitness, psychosocial well-being and physical functioning.  Interestingly data indicates that in Europe only between 11% and 39% of amputees take part in sport, compared to an estimated 61% in the USA.  Studies have identified different factors influencing participation in sports for this group, but there is no overall agreement.  The review provides brief information on limitations on certain activities such as running and long-jumping and the role of prosthetic limbs (although the evidence suggests that most do not use prostheses [note: most of these studies are at least 10 years old]).  Cardiopulmonary function was better when a simple physical exercise programme was included (the intensity of which needs to be tailored to individual abilities).

The psychological impact of the disability on athletes with limb amputations was found to be smaller as compared to those with other disabilities.  Participation in sports and physical activities had a positive influence on self-esteem, perceived body image and locus of control.  In general the benefits of sports participation outweigh the inconvenience of the disability. There is some indication that participants improve their mobility skills, personal relationships and the acceptance of their own disability.  The evidence in relation to physical functioning, mobility and activity level including age, aetiology, amputation level and previous sports participation is mixed and difficult to draw conclusions.  Sport-related muscle pain was more frequent among limb amputees than others with different physical disabilities.  The limited nature of the research made it difficult to identify disability-specific injury rates or patterns.  Also the sports which individuals with limb amputations prefer – fishing, swimming, golf – were not investigated.

The authors caution that the review findings should be treated with caution because only few studies had a high methodological value.  However, their overall conclusion is that participating in sports or physical activity is beneficial for those with lower limb amputations, with the psychosocial benefits being at least equal to those experienced by able-bodied people.  Further research should focus on the inclusion of a larger variety of sports and individuals with upper limb amputations and the influence of sports on quality of life needs to be more thoroughly investigated, along with determinants of participation.  Finally a physical training programme to improve cardiopulmonary function as part of a rehabilitation programme should be developed and tested for its efficacy.

Country of research

Summary of findings

The author provides definitions of stress, anxiety and physical activity and the nature of the inter-relationships between. The role of physical activty in anxiety prevention and treatment is explored via a review of six meta-analytic reviews. A review of several narrative reviews is also provided in which 73 per cent of the studies reported anxiety-reducing effects, with chronic exercise lasting nine or more weeks fairly consistently leading to greater reductions in trait anxiety.

The review considers the extent to which literature for 1989 has confirmed or clarified understanding of (i) the anxiety-reducing effects of  both chronic and acute physical activity and (ii) the effects of both types of activity on reactivity to stress.

The review concludes:

1. The low-to-moderate anxiety-reducing effect of physical activity
2. A period of exercise training can reduce trait anxiety
3. Single exercise sessions will reduce state anxiety
4. Single sessions of moderate exercise can reduce short-term physiological reactivity to and enhance recovery from brief psychosocial stressors
5. Exercise training can reduce trait anxiety across a range of sub-groups
6. Exercise training has been used successfully to reduce trait anxiety in  a range of clinical and non-clinical settings
7. Exercise training appears to have the greatest trait anxiety-reducing effects when the duration is at least 10 weeks (with greatest benefits over 15 weeks)           
8. Trait anxiety-reducing effects are not dependent on changes in physical fitness
9. Single (acute) exercise sessions appear to have the greatest state anxiety-reducing effects when the exercise type if aerobic and rhythmic

Limitations in knowledge include:

1. The long-term effects of accumulated doses of activity.
2. The anxiety-reducing effects of short-term bouts of free-living, unsupervised aerobic, physical activity which can be most easily integrated into an active life-style
3. The anxiety-reducing effects of non-aerobic exercise such as weight and circuit training
4. The influence of social interactions on anxiety in exercise settings
5. The determinants of adherence to free-living and facility-based exercise programmes                

The implications for the exercise practitioner are:

1. Exercise sessions should provide a distraction from worry and anxiety-inducing thoughts and provide the exerciser with a sense of mastery and achievement
2. Exercise testing and programming should  should involve individual contact and goal setting  which supports positive change in self-perceptions
3. Exercise sessions should be incorporated into daily living
4. A supervised exercise programme may provide an important setting for the initiation of an anxiety-reducing intervention if the exercise practitioner has an adequate understanding of the anxiety-reducing mechanisms involved

The key messages outlined in this review are:

• There is growing evidence demonstrating that exercise can be effective in improving the mental well-being of the general public, largely through improved mood and physical self-perception. Evidence for its contribution to the development of global self-esteem is more limited. There is good evidence that aerobic and resistance exercise enhances mood-states and weaker evidence that exercise can improve cognitive function in older adults (primarily assessed by reaction time).
  
• There is good evidence to demonstrate that exercise is effective as a treatment for clinical depression and state and trait anxiety.
  
• Together this adds to the already convincing literature that exercise reduces morbidity and mortality from coronary heary disease, diabetes, obesity and cancers.

There is little evidence to suggest that exercise addiction is identifiable in more than a very small percentage of exercisers. Together, this body of research suggests that moderate regular exercise should be considered as a viable means of treating depression and anxiety and improving mental well-being in the general public. Possible mechanisms for such positive effects are explored:

• Biochemical. It is suggested that the endorphin effect is not widespread and studies have not found a corrrelation between endorphin levels and mood. The extent to which there is an interaction between exercise, central serotonin and improved mood remains unknown.
  
• Physiological. Increased fitness may not be the trigger for change although it may eventually accompany it. Process factors associated with regular participation in exercise rather than change in functional status seem to be more salient to mental well-being change. Other possible factors include increased muscle relaxation, cerebral blood flow and neurotransmitter efficiency.
  
• Psychosocial. Possible factors include improvements in perceptions of competence and self-efficacy; confidence about the body and its capabiliities may generalise to global self-esteem; improved body image (especially for females); social affiliation and significance.

It is likely that multiple mechanisms are effective in any one situation. The dominance of any one mechanism will be determined by exercise characteristics (intensity and duration), characterisitics of the individual and environmental factors surrounding the exercise. Current evidence suggests that process may be more significant than physiological adaptations.

The interactive effect of diet and exercise and mental well-being has not been systematically researched.

The author concludes that exercise should be promoted regardless of its impact on mental health, as it carries significant reduction in risks for a range of diseases and disorders. There is no definitive exercise recommendation for all elements of mental health promotion, as it is likely that the different formulas of frequency, intensity and duration apply for different mechanisms and perhaps different populations.

Expand Physical activity behaviors and emotional self-efficacy: Is there as relationship for adolescents

Summary of findings

This study explored the relationships between physical activity behaviours and emotional self-efficacy of 2,566 school pupils (40% female; aged 12-18) in South Carolina. 

The article provides a brief review of research on the relationship between teenage physical activity and a range of psychological factors, including the importance of self-efficacy in influencing participation in physical activity. 

This research explores one aspect of self-efficacy – emotional self-efficacy, or the perceived capability of coping with negative emotions.  The authors conclude that no previous research examined the relationship between physical activity and emotional self-efficacy among adolescents. 

To undertake such a study the authors drew a representative sample from the 2003 Youth Risk Behaviour Survey.  Data were collected via a emotional self-efficacy (ESE) questionnaire using Likert scales to explore attitudes to various issues such as how well respondents controlled their emotions, how well they could cheer themselves up if feeling low, how much they worried about things that might happen.  Data on nature, type and intensity of physical activity in the past seven days were collected.  The data were analysis for four race[black/white]/gender groups.  Significant relationships were found between low ESE and three of four low level physical activity behaviours among black females, white females, black males and white males. 

The authors conclude that the study demonstrates a meaningful association between two distinct adolescent health research literatures: health risk behaviour (low PA) and ESE and confirms previous related research findings.  They conclude that the data indicate three potentially important pathways in understanding why low ESE appeared to be associated with decreased PA. 

1. Where individuals are placed in situations where they are required to meet highly valued standards they may face anticipatory apprehension and lowered ESE.  

2. A low sense of affect regulation may obstruct the positive benefits offered by participation in physical activity (especially team sport).  

3. Low ESE regarding the ability to have control over negative thoughts and feelings may inhibit youth in a variety of ways and may lead to increased anxiety and depression. 

The authors note important limitations with their study.  Firstly, the cross-sectional design precluded firm conclusions as to whether those who did not tale part in physical activity did not do so because of low ESE or whether they reported low ESE owing to a lack of physical activity.  Further, the study provided no information about the mechanisms for the development of ESE, the extent to which they may vay between males and females and therefore little advice for practitioners

Expand Physical Activity Behaviors and Perceived Life Satisfaction among Public High School Adolescents

Keywords

Psychological well-being; physical activity; sport; children; adolescents; boys; girls

Country of research

Summary of findings

This article is based on a survey of 4,758 pupils, representative of all public high school students in grades 9 to 12 in South Carolina.  It investigates the relationship between life satisfaction and self-reported physical activity.  

The associations were investigated separately for race and gender.  The life satisfaction scale had six domains: family; friends; school; self; living environment; overall life satisfaction.

Results indicate significant relationships between self-reported life satisfaction and non-involvement in physical activity and this relationship was significantly influenced by gender and ethnicity.  

The authors suggest that white females playing on a sports team appears to be protective.  This suggest that team sports serve to enhance school connectedness, social support and peer bonding and may have a greater value than regular exercise.  

For both black and white males it appears that regular exercise, stretching exercise, PE classes and playing on a school sports team are protective for perceived life satisfaction.  

The authors acknowledge methodological limitations: the study is cross-sectional and cannot address the issue of causation; and the geographical sample may not be representative of the general population. Despite these limitations they suggest that participation in sports teams for physical activity may enhance the physiological and psychological well-being contributing to the life satisfaction for adolescents.  They conclude that further research is required into the mechanisms that might explain the significant gender differences.

Expand Effects of physical activity on emotional well-being of older Australian women:cross-sectional and longitudinal analyses

Summary of findings

This longitudinal and cross-sectional study explored relationships between physical activity and mental health in a large cohort of Australian women in their 70s. Women participating in the Australian Longitudinal Study on Women’s Health responded in 1996 and 1999. Cross-sectional data were analysed for 10,063 women and longitudinal data for 6472. Self-reports were used to categorise women into four categories of physical activity at each point, as well as to define four physical activity transition categories across the 3-year period. Outcome variables for the cross-sectional analyses were mental health components score (MCS) and mental health sub-scales of the Medical Outcomes Study Short form (SF-36). The longitudinal analyses focused on changes in these variables. Confounders included the physical health component scale (PCS) of the SF-336, marital status, body mass index (BMI) and life events. Adjustment for baseline scores was included for the longitudinal analyses. Cross-sectionally, higher levels of physical activity were associated with higher scores on all dependent variables, both with and without adjustment for confounders. Longitudinally, the effects were weaker, but women who had made a transition from some physical activity to none generally showed more negative changes in emotional well-being than those who had always been sedentary, while those who maintained or adopted physical activity had better outcomes. The authors conclude that physical activity is associated with emotional well-being among a populations cohort of older women both cross-sectionally and longitudinally, supporting the need for the promotion of appropriate physical activity in this age group.

Expand Physical exercise and psychological well-being: a critical review

Summary of findings

This offers a critical examination of evidence relating to the relationship between physical exercise and psychological benefits. The review examines existing literature on exercise and mental health in relation to changes in anxiety, depression, mood, self-esteem, and stress reactivity, premenstrual syndrome and body image. The general conclusion is that a range of exercise regimens may be able to play a therapeutic role in relation to a number of psychological disorders. The authors argue that enthusiasm for the positive effects of exercise on psychological well-being must be tempered with an acknowledgement of potential danger, such as exercise addiction and body image. Existing research suggests that different forms of physical exercise may be palliative in relation to particular conditions and different psychological conditions respond differently to differing exercise regimens.

With regard to depression the authors conclude that it seems safe to accept that physical exercise regimens will have a positive influence, with the most powerful effects noted among clinical populations. Limited evidence would suggest that aerobic exercise is most effective, including activities such as walking, jogging, cycling, light circuit training and weight training and that regimens which extend over several months appear to yield the most positive results.

With regard to anxiety the literature unequivocally supports the positive effects of exercise, with short bursts of exercise appearing to be sufficient. In addition, the nature of the exercise does not appear to be crucial, with the most positive effects being among those who adhere to programmes for several months.

In respect of stress responsivity the role that exercise plays is described as preventive rather than corrective and there are unaswered questions about the relationship between stress and physiological and psychological symptoms. Nevertheless, it would appear that aerobic exercise (of sufficient intensity to elevate the heart rate significantly above resting pulse rate for over 21 minutes) may significantly enhance stress responsivity, especially in relation to stress related to lifestyle or work.

In respect of mood states both aerobic and anaerobic exercise can be associated with an elevation of mood state, particularly for clinical samples, although it is likely that more than one underlying mechanism may be implicated.

With regard to self-esteem the more specific subdomains of perceived sport competence, physical condition, attractive body and strength may be associated differentially with behaviour in various sports. However, the literature gives little guidance as to which forms of exercise may be beneficial to which types of self-esteem.

With regard to premenstrual syndrome (PMS) the evidence points to the benefits of exercise, with less strenuous forms of non-competitive exercise most effective. The type of exercise, its duration and length still await clarification.

It is very difficult to establish precise guidelines with regard to the intensity and duration of exercise, partly because of methodological difficulties inconsistencies across studies. Overall three main factors are considered when explaining why more definitive conclusions cannot yet be reached. Firstly, the research base remains thin and primary data are not extensive. Secondly, it is not yet clear how psychological and physiological processes and functions interact in the determination of outcomes. Thirdly, the primary mechanisms that underlie the relation between exercise and psychological well-being remain poorly understood.
