Changes in body-related self-conscious emotions over time among youth female athletes.

The current study explored change in body-related self-conscious emotions (e.g., shame, guilt, authentic pride, hubristic pride) over three years, and tested body surveillance, age, weight status, years in sport, and competitive status as baseline predictors of change. Adolescent females engaged in organized sport (N = 518 at baseline, Mage = 14.02, SD = 1.38 years) completed a self-report survey once a year for three years (n = 293 and n = 215 in Years 2 and 3, respectively). Based on the unconditional latent growth model, body-related shame and guilt increased over time, and authentic and hubristic pride decreased over time. There was substantial between-person variability in the intercepts for all emotions and slopes for shame, guilt, and hubristic pride. In the conditional parallel process latent growth model, body surveillance predicted shallower change in shame and guilt over time. Female athletes high in body surveillance also reported higher body-related shame and guilt and lower authentic and hubristic pride at baseline. These findings highlight the importance of studying changes in self-conscious emotions over time in sport, and demonstrate that body surveillance may be an important factor to explore in interventions early in development.

Standards of reporting: the use of CONSORT PRO and CERT in individuals living with osteoporosis.

The Consolidated Standards of Reporting Trials for Patient-Reported Outcomes (CONSORT PRO) and the Consensus on Exercise Reporting Template (CERT) have been developed to improve the quality and transparency of reporting standards in scientific research. The purpose of this study was to provide evidence for the adoption of CONSORT PRO and CERT by researchers examining the link between exercise and quality of life in individuals living with osteoporosis. A systematic search was conducted to identify randomized control trials published in English evaluating exercise interventions on quality of life in individuals living with osteoporosis. Reporting standards were assessed using CONSORT PRO and CERT. A total of 127 studies were identified with 23 meeting inclusion criteria. "Good" evidence for eight (42.1%) CONSORT PRO and two (12.5%) CERT items was found. Adherence to CONSORT PRO was not related to the year of publication, journal impact factor, or study quality. Adherence to CONSORT PRO and CERT reporting standards is inadequate in the literature examining exercise interventions on quality of life in individuals living with osteoporosis. Sufficient reporting is paramount to knowledge translation, interpretation by interventionists, and clinician confidence in understanding if (and how) exercise is associated with quality of life outcomes in this cohort. Concerns associated with failure to include this information are highlighted.

Relative importance of body composition, osteoporosis-related behaviors, and parental income on bone speed of sound in adolescent females.

INTRODUCTION: Adolescence provides a unique opportunity to employ strategies aimed at optimizing peak bone mass yet there are limited studies on the relationship between specific social constructs, osteoporosis-related behaviors, and bone health status in adolescent females. The purpose of this study was to examine associations between bone speed of sound (SOS) and body composition, osteoporosis-related health behaviors, and parental income in adolescent females. METHODS: Four hundred forty-two female students in grades 9-12 from schools in Southern Ontario, Canada were measured for height, body mass, and percent body fat and completed a battery of instruments to assess osteoporosis-related health behaviors. Bone SOS was measured by transaxial quantitative ultrasound at the distal radius and midtibia. RESULTS: Percent body fat was a negative correlate of tibial SOS. No significant correlation was found between physical activity and bone SOS yet physical activity was negatively related to adiposity. Hierarchical regression showed that age and percent body fat were the most important predictors of the variance in tibial SOS scores, with calcium intake having a weaker, yet significant, relationship. Age was the only statistically significant predictor of radial SOS. Users of oral contraceptives had higher radial SOS when controlling for age. Higher parental income was not associated with bone SOS but positive associations between parental income, daily calcium intake, and weekly physical activity were noted. CONCLUSIONS: Bone SOS is reduced in adolescent females with increased adiposity, whereas it is positively influenced by oral contraceptives and daily calcium intake.

Physical activity and subjective well-being among people with spinal cord injury: a meta-analysis.

STUDY DESIGN: Meta-analysis of cross-sectional, quasi-experimental and experimental studies. OBJECTIVE: To determine if there is an association between physical activity (PA) and subjective well-being (SWB) among people living with spinal cord injury (SCI). METHODS: Literature searches were conducted using multiple databases (Embase, CINAHL, Medline, PsychINFO and SPORTDiscus) to identify studies involving people with SCI that included a measure of PA and at least one measure of SWB (for example, symptoms of depression, life satisfaction, mood). Relevant data were extracted from the studies and subjected to meta-analysis. RESULTS: A total of 21 studies were retrieved yielding 78 effect sizes and a total sample size of 2354. Overall, there were statistically significant, small- to medium-sized effects for the relationships between PA and SWB (broadly defined), PA and depressive symptoms, and PA and life satisfaction. Studies using experimental and quasi-experimental designs yielded larger effects for SWB (broadly defined) and life satisfaction, than studies using nonexperimental study designs. CONCLUSIONS: There is a small- to medium-sized positive relationship between PA and SWB among people with SCI that holds across a wide range of measures and operational definitions of these constructs.

The relation of self-efficacy measures to sport performance: a meta-analytic review.

This meta-analysis examined the relationship between self-efficacy and performance in sport. Based on 45 studies (102 correlations), the average correlation between self-efficacy and sport performance was .38. Given the heterogeneity of findings, follow-up univariate and multivariate moderator analyses were conducted. Results indicated that the most important moderator was concordance, thereby highlighting the importance of matching the self-efficacy and performance measures. Additional moderators we examined included the types of self-efficacy measures, the types of performance measures, the nature of the task, and the time of assessments. These variables accounted for approximately 44% of the variance in the self-efficacy-performance relationship. Practical implications of the findings are discussed.
