Self-regulation and self-control in exercise: The strength-energy model

Self-regulation is an important component of psychosocial theories of exercise behaviour and lack of self-regulatory skills are associated with low adherence to health-related exercise. This review presents a strength-energy model of self-control as an explanation of self-regulation in exercise contexts. The review will provide impetus for original research aimed at understanding exercise behaviour and help develop recommendations for exercise promotion. In the model, self-control is conceptualized as a global but limited resource. Engaging in actions requiring self-control depletes resources leading to self-regulatory failure. Self-control resource depletion is reduced through rest and frequent training on self-control. The expectation of the need to exert self-control in future leads to a conservation of self-control resources. Proposed mechanisms for self-control resource depletion include changes in physiological markers and blood glucose levels. Based on our review, we propose an integrated model of self-regulation incorporating hypotheses from the strength-energy model with those from traditional psychosocial models of exercise behaviour. Recommendations for future research include incorporating hypotheses from the strength-energy model into theories of self-presentation and interpersonal relations in exercise. Practical recommendations aimed at minimising self-control depletion in exercise include the provision of advice on nutrition and recovery, self-control training and motivational and implementation intention strategies

Reflection and the art of coaching: fostering high-performance in olympic ski cross

In preparation for the 2010 Vancouver Winter Olympic Games, the lead author engaged in systematic reflection in an attempt to implement coaching behaviours and create practice environments that promoted athlete development (psycho-social and physical performance). The research was carried out in relation to his work as head Ski Cross coach working with (primarily) three athletes in their quest for Olympic qualification and subsequent performance success in the Olympic Games. This project sought to examine coach-athlete interactions. Of particular interest were coach and athlete responses regarding the implementation of autonomy supportive coaching behaviours in a high context. Autonomy supportive coaching behaviours have previously been strongly associated with positive athlete psycho-social and performance outcomes, however, a paucity of research has examined its implementation in high-performance contexts. Through the use of participant ethnography, it was possible to gain considerable insights regarding athletes' perceptions of choice, implications of perceived athletic hierarchies, as well as cultural and experience-related influences on training and performance expectations

Influences of perceived autonomy support on physical activity within the theory of planned behavior

Three studies tested the contribution of perceived autonomy support to the prediction of health-related intentions within the theory of planned behavior. Perceived autonomy support refers to the extent to which individuals perceive that significant others encourage choice and participation in decision-making, provide a meaningful rationale, minimize pressure, and acknowledge the individual's feelings and perspectives. Findings from Studies 1 and 2 demonstrated that perceived autonomy support predicted intentions to participate in physical activity behavior directly and indirectly via attitudes. Perceived autonomy support predicted intention even after statistically controlling for the effects from past behavior, descriptive norms, and perceived social support. Study 3 found that persuasive communications influenced perceptions of autonomy support, attitudes, and intentions. Overall, the findings support the incorporation of perceived autonomy support into the theory of planned behavior. Copyright ©2006 John Wiley & Sons, Ltd.link_to_subscribed_fulltex

The influences of intrinsic motivation on execution of social behaviour within the theory of planned behaviour

The present study examined the utility of two forms of measurement of intrinsic motivation in increasing the predictive validity of the theory of planned behaviour. Self-report questionnaires were administered to school pupils (n = 174), University students (n = 129) and adults (n = 157). The data were analysed using confirmatory factor analysis and regression analysis. Confirmatory analysis supported discriminant validity between Forms A and B measures of intrinsic motivation. In addition, hierarchical regression analysis demonstrated that Form B measure of intrinsic motivation increased effectiveness of the theory of planned behaviour in predicting intentions and social behaviour. Further, the regression analysis showed that age and past behaviour did not reduce the effects observed for intrinsic motivation. It is recommended that intrinsic motivation could increase the predictive utility of the theory of planned behaviour. Copyright © 2006 John Wiley & Sons, Ltd.link_to_subscribed_fulltex

The influences of continuation intentions on execution of social behaviour within the theory of planned behaviour

This study explores the predictive accuracy of the theory of planned behaviour (TPB) in relation to continuation of intentions. Three studies examined the hypothesis that continuation intentions of success and continuation intentions of failure would improve utility of the TPB in predicting and promoting social behaviour. As a new construct, continuation intentions of success and continuation intentions of failure aim to describe people's readiness to continue performance of an activity under conditions that signify successful and unsuccessful progress at behavioural outcomes. As predicted, Study 1 (N = 222, male = 107, female = 115, age = 14.62 yrs, SD = 1.45) and Study 2 (N = 200, male =101, female = 98, age = 14.29 yrs, SD = .92) showed that continuation intentions of success and continuation intentions of failure contributed to the prediction of physical activity over and above components of the TPB, past behaviour and perceived progress. Study 3 (N = 93, male = 50, female = 42, age = 20.53 yrs, SD = 3.36), a study of food choice, manipulated continuation intentions and showed that participants who formed continuation intentions were more likely to eat five portions of fruit and/or vegetables than participants in a control group. Together, these findings underscore the theoretical as well as practical importance of distinguishing between intentions and continuation intentions, and the need for influence attempts to manipulate continuation intentions.link_to_subscribed_fulltex

The stability of the attitude-intention relationship in the context of physical activity

Attitude has been shown to be an important antecedent of physical activity intentions and behaviour. It is unclear whether the attitude-intention relationship is stable over time. The aim of the present study was to examine the stability of the attitude-intention relationship over a 6 week period. A panel study of 65 males and 81 females aged 20.6 ± 0.8 years was conducted, in which measures of attitudes, intentions, self-reported physical activity and perceived behavioural control were assessed at the beginning and end of the 6 weeks. The data were analysed using path analysis. Results indicated that the attitude-intention relationship was stable over time. In addition, the behaviour-intention relationship was undermined over time. It is recommended that interventions can facilitate adherence to physical activity by reinforcing attitude change during initial and later stages of treatment

Influences of volitional and forced intentions on physical activity and effort within the theory of planned behaviour

In the present study, we examined the utility of volitional and forced intentions in predicting participation in physical activities and effort within the theory of planned behaviour. Four hundred and forty-four participants (184 males, 260 females) aged 19.1 ± 3.3 years (mean ± s) completed self-report measures of intentions, attitudes, subjective norms, perceived behavioural control, volitional intentions, forced intentions, and past behaviour in a physical activity context. Six weeks later, they completed self-report measures of physical activity behaviour and effort. Results indicated that volitional intentions and forced intentions contributed to the prediction of effort over and above intentions, attitudes, subjective norms, perceptions of control, past behaviour, and the product terms of attitudestimesintentions and subjective normstimesintentions. Volitional intentions and forced intentions did not predict participation in physical activities over and above effort. We concluded that volitional intentions and forced intentions assist in the explanation of effort in the context of physical activity behaviour

A Meta-Analysis of Perceived Locus of Causality in Exercise, Sport, and Physical Education Contexts

The present article conducts a meta-analytic review of the research adopting the perceived locus of causality in the contexts of sport, exercise, and physical education. A literature search of published articles identified three main research foci: (a) the development of instruments that assess perceived locus of causality; (b) examination of the construct validity of perceived locus of causality by investigating the relevance of the self-determination continuum as well as by using antecedents (e.g., perceived competence) and outcomes (e.g., intentions); and (c) integration of Nicholls’ (1984) concepts of task and ego orientation with perceived locus of causality. A meta-analysis using 21 published articles supported the existence of a self-determination continuum from external regulation to introjection and identification. In addition, path analysis of corrected effect sizes supported the mediating effects of perceived locus of causality on the relationship between perceived competence and intentions. Results are discussed with reference to the assumptions of self-determination theory, Vallerand’s (1997) hierarchical model of intrinsic/extrinsic motivation, and theories of behavioral intentions

Effects of achievement goals on perceptions of competence in conditions of unfavourable social comparisons: The mastery goal advantage effect

Background: Previous prospective studies have documented that mastery-approach goals are adaptive because they facilitate less negative psychological responses to unfavourable social comparisons than performance-approach goals. Aims: This study aimed to confirm this so-called ‘mastery goal advantage’ effect experimentally. Methods: A 2 × 3 design was adopted where achievement goals (mastery vs. performance) and normative information (favourable vs. no-normative information vs. unfavourable) were manipulated as between participant factors. Sample: Participants were 201 undergraduates, 57 males and 144 females, ranging in age from 17 to 55 years (Mage = 22.53, SD = 6.51). Results: Regression analyses pointed out that experimentally induced mastery-approach goals facilitated higher levels of competence and happiness with task performance than experimentally induced performance-approach goals in conditions of unfavourable social comparisons. In contrast, although performance-approach goals yielded the highest levels of happiness with task performance in conditions of favourable social comparisons, this positive effect of performance-approach goals did not extend to perceptions of competence. Conclusion: Current findings broaden understanding of the adaptive nature of mastery-approach goals and suggest that it is possible to modulate aversive responses to unfavourable social comparisons by focusing attention on mastery-approach goals. © 2017 The British Psychological Societ

Clarifying the link between mastery goals and social comparisons in classroom settings

Previous experimental studies have documented that competence evaluations are function of social comparison information pertaining to classmates' grades even among mastery-oriented students who are not supposed to base perceptions of competence on social comparisons. This study aimed to replicate this link between mastery goals and social comparisons by using a measure of achievement goals that captured the comparison standards that students intended to adopt in classroom settings. In addition, we examined whether mastery-oriented and performance-oriented students responded differently to social comparisons, particularly unfavourable social comparisons with more capable classmates. In a study that aimed to predict perceptions of competence among university students, we showed that mastery-oriented students who intended to adopt self-referenced standards of comparison based perceptions of competence on social comparisons. In addition, response surface analysis supported a "mastery goal advantage" effect whereby mastery goals yielded higher perceptions of competence than performance goals among students who engaged in unfavourable social comparisons. Findings suggest that mastery goals are adaptive not because they motivate students to not engage in social comparisons but because they lead students to respond to unfavourable social comparisons in an adaptive way. © 2016
