Background:

Physical activity (PA) declines sharply and rapidly during adolescence, especially among girls, posing a risk for inactivity and obesity in adulthood. This study identified personal, behavioral, and socioenvironmental correlates of concurrent and 6-month longitudinal PA among adolescent girls.

Methods:

Data were gathered from 356 adolescent girls (mean age 15.8 ± 1.2 years; > 75% racial/ethnic minorities) in the Minneapolis/St. Paul area in 2007–2009. Linear regression analyses controlling for age, race/ethnicity, and school were conducted predicting baseline and follow-up levels of total PA and moderate-to-vigorous PA (MVPA) assessed via 3-Day Physical Activity Recall. Models were fit for each correlate individually and for all correlates together, mutually adjusted.

Results:

For concurrent PA, significant positive predictors when adjusting for the influence of all other variables included self-efficacy, support from friends and teachers, and friends’ PA. Total screen time and distance from school to PA resources related inversely to concurrent PA. In mutually-adjusted models, 6-month PA was positively related to self-worth, family support, and parent PA and inversely related to total screen time.

Conclusions:

PA interventions with adolescent girls might be enhanced by involving adolescents’ social networks and also by helping adolescents feel better about their self-worth and athletic abilities.

This study examined exercise-adherence rates and their predictors across 21 randomized controlled trials (RCTs) involving older adults (age ≥ 55 years). On average, participants completed 78% of their prescribed exercise bouts. Adherence tended to be greater in strength- and flexibility-exercise training programs (M = 87%) than in aerobic-exercise training programs (M = 75%). The best adherers were individuals who were fitter at baseline, had a history of a physically active lifestyle, were nonsmokers, and had higher exercise self-efficacy. Different variables predicted adherence (a) at different time points in a RCT. (b) to different types of exercise, and (c) to different aspects of the exercise prescription (i.e., frequency, intensity, and duration). The findings suggest that older adults might be more adherent to exercise prescriptions than younger adults are. There is also a need for more theory-based research to examine predictors of adherence to various aspects of the exercise prescription.

examining predictors of athlete’s emotions that span objective and normative indices of success (i.e., medals won) versus objective expectations (i.e., medal won relative to medal expected) and self-referenced expectations (i.e., race times relative to previous personal best times) appears nonexistent. Such

Objective:

To explore predictors of recovery time.

Design:

Repeated measures on 4 occasions throughout recovery included injury appraisal, demographics, emotional responses, and psychological variables.

Participants:

Elite injured athletes (N = 136).

Main Outcome Measure:

Recovery time.

Results:

At all phases, being a team athlete was a significant predictor of faster recovery. At partial recovery (approximately one-third of the recovery time), significant predictors were active coping, confidence of reaching full recovery in the estimated time, not completing rehabilitation, and having less social support. By semirecovery (approximately two-thirds of the recovery time), vigor and using denial significantly predicted quicker recovery. At recovery, having previously suffered a serious nonsporting injury or illness, vigor, more confidence, and intensity of effort significantly predicted faster recovery.

Conclusions:

This study has expanded on and refined the work in this area and will help increase understanding of the role that psychological variables play in decreasing recovery time, which has important implications for those implementing rehabilitation programs.

Recent findings have suggested that neither chronological age nor global cognitive status is predictive of retained improvements ( Schaefer, Dibble, & Duff, 2015 ; Schaefer & Duff, 2015 ), while

The use of the FMS to identify movement quality and potential risk for injury has grown in recent years, however, debate remains as to the usefulness of composite FMS score to predict injury. The composite score has

The volleyball attack is the action winning most of the points during a game, and attack effectiveness (AE) is consequently thought to be one of the most important predictors of victory. 1 , 2 It can be performed in a number of ways, most commonly in the form of a “spike.” This is a unique
