The purpose of the present investigation was to extend the literature on the relationship between goal specificity, goal proximity, and performance by using high school students and attempting to control for the effects of social comparison. Subjects (N=214) in Experiment 1 were randomly assigned to one of five goal-setting conditions: (a) short-term goals, (b) long-term goals, (c) short- plus long-term goals,(d) do-your-best goals, and (e) no goals. After a 3-week baseline period, subjects were tested once a week on the 3-minute sit-up over the course of the 10-week experimental period. Results indicated that the short- plus long-term group exhibited the greatest increase in performance although the short-term and long-term groups also displayed significant improvements. In Experiment 2, a short- plus long-term group was compared against a do-your-best group. Results again revealed a significant improvement in performance for the combination-goal group whereas the do-your-best group did not display any improvement.

Based on Vygotsky’s theory of cognitive development and its concept of zone of proximal development, this study examined how the skill level of a peer tutor affects the achievement motivation of novice learners and their performance in a swimming task. Gender differences were also explored. High school students (N = 48) were assigned in a 2 × 3 (Gender × Tutor skill level: novice vs. intermediate vs. skilled) factorial design. Participants were invited to observe a same-sex peer tutor, complete a self-efficacy questionnaire, train with their tutor for 8 minutes, and complete a goal involvement questionnaire. Results demonstrated that skilled tutors yielded the best swimming skills for boys, whereas skilled and intermediate tutors yielded better skills than did novice tutors for girls. The skilled tutor group led to higher self-efficacy for improvement and gave more demonstrations and verbal information than did the novice group. Male tutees adopted higher ego involvement goals and trained more physically, whereas female tutees adopted higher learning goals and received more demonstrations and verbal instructions. Results are discussed in relation to educational studies conducted in a Vygotskian perspective.

This study examined changes in multiple physical activity domains during the transition out of high school and psychosocial and environmental determinants of these changes.
A 1-year prospective study was designed. The baseline sample was composed of 244 last-year high school students (58.6% female) from Valencia, Spain. Follow-up rate was 46%. Physical activity and potential determinants were measured by the Global Physical Activity Questionnaire and other evaluated scales in 2 waves.
Total physical activity and active commuting (AC) decreased, respectively, by 21% and 36%, only in males. At time 1, access to car/motorbike (inverse), planning/psychosocial barriers (inverse), street connectivity (positive) and parental education (inverse) were significantly associated with AC (P < .05). Prospectively, the increase in distance to school/workplace was associated with AC decrease among males (P < .001). In both genders, there was a decrease in leisure-time physical activity (LTPA; –35% in males, –43% in females). At time 1, self-efficacy and social support were positive correlates of LTPA (P < .05). Social support decreases were associated with reductions in LTPA for males (P < .05).
Several psychosocial and environmental correlates of physical activity change were identified, and these are promising targets for interventions.

More than 1 million US high school students play football. Our objective was to compare the high school football injury profiles by school enrollment size during the 2013–2014 season.
Injury data were prospectively gathered on 1806 student athletes while participating in football practice or games by certified athletic trainers as standard of care for 20 high schools in the Atlanta Metropolitan area divided into small (<1600 students enrolled) or large (≥1600 students enrolled) over the 2013–2014 football season.
Smaller schools had a higher overall injury rate (79.9 injuries per 10,000 athletic exposures vs. 46.4 injuries per 10,000 athletic exposures; P < .001). In addition, smaller schools have a higher frequency of shoulder and elbow injuries (14.3% vs. 10.3%; P = .009 and 3.5% vs. 1.5%; P = .006, respectively) while larger schools have more hip/upper leg injuries (13.3% vs. 9.9%; P = .021). Lastly, smaller schools had a higher concussion distribution for offensive lineman (30.6% vs. 13.4%; P = .006) and a lower rate for defensive backs/safeties (9.2% vs. 25.4%; P = .008).
This study is the first to compare and show unique injury profiles for different high school sizes. An understanding of school specific injury patterns can help drive targeted preventative measures.

Physical activity (PA) declines as adolescents get older, and the motivational determinants of PA warrant further investigation. The purposes of this study were to investigate the amount of physical and sedentary activity that adolescents participated in across age, gender, and race, and to investigate adolescents’ attraction to PA and their perceived barriers and benefits across age, gender, and race.
High school students (N = 1163) aged between 13 and 16 years completed questionnaires on minutes and intensity of physical and sedentary activity, interests in physical activity, and perceived benefits and barriers to participating in PA.
A series of multivariate analyses of variance were conducted and followed up with discriminant function analysis. PA participation decreased in older females. In addition, fun of physical exertion was a primary attraction to PA for males more than females. Body image as an expected outcome of participating in PA contributed most to gender differences.
There is a need to determine why PA drops-off as females get older. Findings underscore the importance of structuring activities differently to sustain interest in male and female adolescents, and highlights motives of having a healthy body image, and making PA fun to enhance participation.

Social support (SS) from parents and peers are key reinforcing factors in the Youth Physical Activity Promotion (YPAP) model. This study aims to identify the relative contribution of parental and peer SS on youth participation in moderate to vigorous physical activity (MVPA). Participants included 203 high school students (n = 125 girls; mean age 14.99 ± 1.55 years). MVPA was assessed by accelerometry. SS influences were evaluated using a well-established scale. Structural equation modeling measured (AMOS, Version 19) the relative fit of the YPAP models using both parental and peer SS. Parental SS had significant associations with both predisposing factors, enjoyment (β = .62, p < .01), and self-efficacy (β= .32, p < .01), as well a direct effect on MVPA (β = .30, p < .01). Peer SS had direct effect on MVPA (β = .33, p < .05), also significantly influenced levels of enjoyment (β = .47, p < .01) and self-efficacy (β = .67, p < .01). In both models self-efficacy mediated the influence on MVPA. The direct effects for parents and peers were similar. This demonstrates that both parental and peer social support exert a strong influence on adolescent MVPA.

Physical activity (PA), television time (TV), and sleep duration (SLP) are considered individual risk factors for adolescent obesity. Our aim was to investigate the concurrent influence of meeting PA, SLP, and TV recommendations on adolescent obesity utilizing 2011 Youth Risk Behavior Surveillance Survey (YRBSS) data.
Subjects included 9589 (4874 females) high school students. PA, SLP, and TV were categorized utilizing established national recommendations and youth were cross-tabulated into 1 of 8 groups based on meeting or not meeting each recommendation. Logistic models were used to examine the odds of obesity for each group. Results: Youth meeting the PA recommendation were not at increased odds of obesity, regardless of SLP or TV status. However, not meeting any single recommendation, in general, led to increased odds of not meeting the other two. In boys, 11.8% met all recommendations while 14.1% met 0 recommendations. In girls, only 5.0% met all recommendations while 17.8% met none.
Boys and girls not meeting any of the recommendations were 4.0 and 3.8 times more likely to be obese compared with their respective referent groups. Further research considering the simultaneous influence these risk factors may have on obesity and on one another is warranted.

This study sought to determine the relationships between the cognitive styles field dependence-independence and reflection-impulsivity and the acquisition of a gross motor skill in an unstructured learning environment. In reference to the first cognitive style construct, it was hypothesized that field-independent subjects perform better than field-dependent subjects because they provide organization when the material to be learned lacks structure, leading them to rely on their analyzing and restructuring ability. The second construct refers to cognitive inhibition required for response uncertainty tasks as well as motor impulse inhibition. Subjects (57 boys, 65 girls) were 13-year-old junior high school students. Several visual perceptual tests were administered and gymnastic performance scores were measured at pretest, during the learning session, and posttest. The hypothesis that field-independent subjects are more successful in an unstructured learning environment than field-dependent subjects was confirmed for boys only. The correlations between the reflection-impulsivity variables and gymnastic performance were generally low, and no support could be found for the hypothesis that reflective subjects are more successful in learning the skill than impulsive subjects.

The present investigation demonstrated cross-cultural support for convergent and discriminant validity of the Physical Self-Description Questionnaire (PSDQ) in a multitrait-multimethod analysis of relations with responses to the Physical Self-Perception Profile (PSPP). The sample, 1,041 Turkish university students in elective physical education courses from 10 Turkish universities, provided a test of the cross-cultural generalizability of responses to these two widely used English language instruments. In support of construct validity interpretations, matching PSDQ and PSPP factors were highly correlated. However, support for the PSPP was undermined by extremely high correlations among several of its factors, due in part to a substantial method effect associated with its idiosyncratic response scale. Results based on this study with Turkish university students largely replicate and extend the findings of Marsh et al. (1994) with Australian high school students. Based on psychometric, theoretical, cross-cultural, and practical considerations, the results support the use of the PSDQ in a wide variety of research and applied settings.

Background: Interventions promoting physical activity (PA) in youth have had limited success, in part because studies with methodological challenges have yielded an incomplete understanding of personal, social, and environmental influences on PA. This study described changes in these factors for subgroups of youth with initially high PA that decreased (Active-Decline) compared with children with initially low PA that decreased (Inactive-Decline) from fifth to ninth grades. Methods: Observational, prospective cohort design. Participants (n = 625) were fifth-grade children recruited in 2 school districts and followed from elementary to high school. Students and their parents responded to questionnaires to assess personal, social, and perceived physical environmental factors in the fifth (mean age = 10.5 [.5] y) and ninth (mean age = 14.7 [.6] y) grades. Analyses included a mixed-model 2-way repeated analysis of variances. Results: Children in the Active-Decline compared with those in the Inactive-Decline group showed a more favorable profile in 6 of 8 personal variables (perceived barriers, self-efficacy, self-schema, enjoyment, competence, and fitness motives) and 4 of 6 social variables (friend support, parent encouragement, parent support, and parent-reported support). Conclusions: The results suggest efforts to promote PA should target selected personal, social, and perceived environmental factors beginning before age 10 and continuing through adolescence.
