Context: Upper limb activities require a repetitive movement of the shoulder external rotator and abductor muscles. The malfunction of the proximal part of the upper limb kinetic chain tends to change the mechanics of the distal part and increase the risk of injuries. Objectives: To compare the normalized eccentric peak torque (NEPT) of the shoulder external rotator and abductor muscles among healthy athletes and those with tennis elbow and golfer’s elbow. Design: An experimental cross-sectional study. Setting: Isokinetic laboratory, Faculty of Physical Therapy, Cairo University. Participants: A total of 30 male athletes participated voluntarily in this study. Intervention: Participants were distributed into 3 groups: healthy group, tennis elbow group, and golfer’s elbow group. Main Outcome Measures: NEPT of shoulder abductors and external rotators. The Biodex Isokinetic Dynamometer was used to measure the variables of interest. Results: There was a significant increase in the NEPT of shoulder abductors and external rotators in healthy control group compared with both tennis elbow and golfer’s elbow groups at an angular velocity of 60°/s (P < .05). Moreover, there was a significant increase in the NEPT of shoulder external rotators and abductors at an angular velocity of 120°/s in healthy control group compared with tennis elbow group and in golfer’s elbow group compared with tennis elbow group (P < .05). Conclusion: Tennis elbow and golfer’s elbow are associated with decreased NEPT of shoulder external rotators and abductors compared with those of healthy athletes. This tends to decrease the external stability of the shoulder joint and put high stress on the distal joints of the upper kinetic chain.

Purpose: The landscape of physical education has shifted in the 30 years since Metzler and Freedman’s seminal study examining the demographics of physical education teacher education faculty. Changes in the structure of physical education and academia justify an updated investigation, with particular emphasis on the gender and institutional affiliation of faculty. Methods: An expanded and validated version of Metzler and Freedman’s survey was e-mailed to 908 physical education teacher education faculty from 505 U.S. institutions. A response rate of 46.21% was achieved. The data were analyzed using descriptive and inferential statistics to examine differences based on gender and institutional affiliation. Results: Gender salary disparities have decreased, whereas teaching experience and qualifications of faculty have increased. Corresponding increases in research productivity were notably evident. Discussion/Conclusion: Faculty members remain predominately European American, publication output has increased, more institutions are hiring nontenure-track faculty, and perceptions of support for physical education are lower than in 1985.

Purpose: This study assessed students’ levels and associations between recess enjoyment, positive affect, environmental factors, and activity preferences overall and as a function of gender and developmental level. Methods: An online survey was used to gather data from 464 students in Grades 4–8 from nine elementary schools in southwestern Ontario, Canada. Results: When the variance explained by gender and developmental level was controlled for in this study, both recess environment and activity preferences accounted for a significant portion of the variability related to affect and enjoyment of recess. Having equipment and space and preference for moderate-to-vigorous physical activity, organizing and playing games, and free time predicted both affect and enjoyment. Conclusion: These and other findings enable educators to progress in understanding how they might adjust approaches to recess to facilitate more enjoyment and positive affect in elementary school students especially by gender and developmental level.

Some older adults may not receive social connection due to social withdrawal, potentially resulting in loneliness. The purpose of this study was to examine relationships between social withdrawal and loneliness, in the context of sports participation. The authors hypothesized that individuals who are more shy and avoidant would be more lonely than those who are less shy and avoidant, and that those who are unsocial would not necessarily be more lonely. The authors also hypothesized individual sport participation would further exacerbate loneliness over group sport participation. Results from participants in the Huntsman Senior Games (n = 374) indicated that as shyness, avoidance, and unsociability increased, loneliness increased as well. Furthermore, shy athletes in group sports reported higher levels of loneliness than those in individual sports. Although the authors seek to prevent individuals from being lonely in later life, there may be instances where removing oneself from a group is beneficial for mental health.

Purpose: To examine the test–retest reliability of student-administered (SA) health-related fitness tests in school settings and to compare indices of reliability with those taken by trained research-assistants. Methods: Participants (n = 86; age: 13.43 [0.33] y) were divided into 2 groups, SA (n = 45, girls = 26) or research-assistant administered (RA; n = 41, girls = 21). The SA group had their measures taken by 8 students (age: 15.59 [0.56] y, girls = 4), and the RA group had their measures taken by 8 research-assistants (age: 21.21 [1.38], girls = 5). Tests were administered twice by both groups, 1 week apart. Tests included body mass index, handgrip strength, standing broad jump, isometric plank hold, 90° push-up, 4 × 10-m shuttle run, back-saver sit and reach, and blood pressure. Results: Intraclass correlation coefficients for SA (≥.797) and RA (≥.866) groups were high, and the observed systematic error (Bland–Altman plot) between test 1 and test 2 was close to 0 for all tests. The coefficient of variation was less than 10% for all tests in the SA group, aside from the 90° push-up (24.3%). The SA group had a marginally lower combined mean coefficient of variation across all tests (6.5%) in comparison with the RA group (6.8%). Conclusion: This study demonstrates that, following familiarization training, SA health-related fitness tests in school-based physical education programs can be considered reliable.

Integrating the Student-Athlete Climate Study conceptual framework with critical race and intersectionality theories, I examine racial differences in the perceived effects of college on life skill development among college sportswomen. I use nationally representative data from the NCAA’s 2006 Growth, Opportunity, Aspirations, and Learning of Students in College (GOALS) survey to examine whether team and/or campus climate mediate racial differences. I find small, but statistically significant differences whereby sportswomen of color report less positive effects of college on leadership, teamwork, time management, and work ethic compared to white sportswomen, but more positive effects of college on their understanding of people of other races. Campus climate, but not team climate, partially mediates racial differences in the perceived effects of college on leadership, teamwork, time management, and work ethic.

This study compared salivary and serum concentrations of testosterone and cortisol at rest and in response to intense multitask exercise in boys and men. Early morning saliva and venous blood samples were obtained before and 15 minutes after exercise from 30 competitive swimmers (15 boys, age 14.3 [1.9] y; 15 men, age 21.7 [3.1] y). Exercise included a swim-bench maximal strength task and an all-out 200-m swim, followed by a high-intensity interval swimming protocol (5 × 100 m, 5 × 50 m, and 5 × 25 m). At baseline, fasting testosterone (but not cortisol) concentration was higher in men than boys in serum and saliva (P < .05). Salivary and serum cortisol increased postexercise, with a greater increase in men compared with boys (men: 226% and 242%; boys: 78% and 64%, respectively; group by time interaction, P < .05). Testosterone was reduced postexercise in serum but not in saliva (men: −14.7% and 0.1%; boys: −33.9% and −4.5%, respectively, fluid by time interaction, P < .01). Serum and salivary cortisol (but not testosterone), preexercise and postexercise values were strongly correlated in both men and boys (r = .79 and .82, respectively; P < .01). In summary, early morning high-intensity exercise results in a decrease in testosterone in serum, but not saliva, and an increase in cortisol irrespective of the fluid used, in both boys and men. When examining immediate postexercise changes, the lack of correlation in testosterone between saliva and serum suggests that saliva may not be an appropriate fluid to examine changes in testosterone. The high correlation observed between serum and saliva for cortisol indicates that, in both boys and men, saliva may be used to monitor the immediate cortisol response to exercise.

Purpose: To address the obesity epidemic and promote children’s health; several health organizations recommend that schools develop comprehensive programs designed to promote physical activity and health behavior. Given a lack of empirical investigation, the authors sought to understand how physical education programs are perceived within such initiatives. Methods: A case study was conducted to acquire insights of key stakeholders (N = 67) in a school nationally recognized for promoting physical activity and health. Data were collected using formal interviews, informal interviews, observations, and document analysis. Data were analyzed utilizing grounded theory and constant comparison. Results: Physical education was viewed positively by stakeholders; however, physical educators felt marginalized within the school infrastructure. Systemic barriers to program quality included lack of leadership, feelings of marginalization, and insufficient funding and collaboration. Discussion: Findings raise concerns about the difficulty of sustaining a high-quality physical education program even in a school recognized for significant support of physical activity.
