The effects of the selective 5HT1A agonist 8-OH-DPAT were assessed on the play behavior of juvenile rats. When both rats of the test pair were comparably motivated to play, the only significant effect of 8-OH-DPAT was for play to be reduced at higher doses. When there was a baseline asymmetry in playful solicitation due to a differential motivation to play and only one rat of the pair was treated, low doses of 8-OH-DPAT resulted in a collapse of asymmetry in playful solicitations. It did not matter whether the rat that was treated initially accounted for more nape contacts or fewer …
Presence Of Observers Increases One Repetition Maximum In College-Age Males And Females, Steven C. Baker, Alan P. Jung, John K. Petrella
Presence Of Observers Increases One Repetition Maximum In College-Age Males And Females, Steven C. Baker, Alan P. Jung, John K. Petrella
International Journal of Exercise Science
Purpose: To determine if the presence of observers affects muscular strength performance in college-age males and females. Methods: Twenty-five women and 24 men participated in the study. Two counter-balanced trials were performed in which participants completed 1-RM tests in bench press and leg press. During one trial, two members of the opposite gender observed the 1-RM tests. During the other trial there were no observers, other than the tester. Results: 1-RM for females increased 3.4±0.8 lbs on bench press (p<.001) and increased 9.2±3.8 lbs on leg press (p=.025) when observers were present. 1-RM for males increased 4.2±1.1 lbs on bench press (p=.001) and increased 18.8±5.2 lbs on leg press (p=.002) with observers present. There was no difference in the percent increase in 1-RM between males and females for either leg press (p=.71) or bench press (p=.08). Conclusion: College-age males and females lifted more weight during a 1-RM test when observers were present.

This article describes the importance of promoting children’s discretionary-time physical activity (DTPA) in connection with the rising international obesity epidemic. School based recess is highlighted as exemplar of an opportunity for children to obtain more DTPA. Brief review of the extant research focused on efforts to increase children’s recess physical activity (RPA) is provided. Literature from the field of sports psychology that has established a strong foundation of evidence regarding factors that increase youth motivation in various physical domain contexts will guide the proposed expansion to theoretical examination of predictors of youth DTPA. Three relevant motivation theory frameworks will be …

School physical education (PE) not only offers and promotes health-related physical activity, but also encompasses the promotion and development of perceptions of mental health (USDHHS, 2010). It has been suggested that health-related quality of life (HRQOL) can predict future health, monitor children’s psychosocial health, and identify those most at risk or in need of support at an early stage. Assessing physical activity (PA) and health-related quality of life have become major issues in pediatric public health and also serve as a major goal of Health people 2020 (USDHHS, 2010). Research including assessment of theory-based mediators of health-related outcomes is needed …

Sources Of Self-Efficacy In Distance Runners, Ashley Ann Samson
LSU Doctoral Dissertations
Self-efficacy theory (Bandura, 1997) asserts that people will be more likely to engage in behaviors that they believe they can successfully perform and avoid behaviors in which they feel that they will be unsuccessful. Researchers have concluded that individuals with high levels of self-efficacy are more likely to pursue challenging goals, cope with pain, and persevere through setbacks, while those with low self-efficacy avoid challenges and tend to give up when confronted with obstacles (Llewellyn, Sanchez, Asghar, & Jones, 2008). Endurance sport, particularly distance running, is a domain in which being able to cope with pain and persevere through setbacks …
