BACKGROUND: Pacific Islanders experience an elevated risk of health conditions such as obesity and diabetes, which are related to a lack of physical activity (PA). However, little attention has been paid to understanding the determinants of PA and promoting PA among this racial/ethnic group in the United States. METHODS: We conducted focus group discussions with Tongan Americans, one of the major Pacific Islander groups in the United States, to gain a better understanding of their PA participation patterns, their barriers and facilitators, their attitudes toward PA, and their perceptions of how mobile technologies such as smartphones could help increase their PA levels...

BACKGROUND: LGBTQ+ (lesbian, gay, bisexual, transgender, queer, etc) persons are subject to elevated rates of chronic diseases and health concerns that can be addressed through regular participation in physical activity. However, LGBTQ+ adults experience unique challenges to engaging in physical activity. Subsequently, the aim of this study is to describe the dominant narratives related to the complex intersection of sexual orientation, gender identity, and physical activity. METHODS: A systematic search and scoping review of existing literature was conducted in June 2016...

OBJECTIVE: Muscular strength has been shown to inversely associate with mortality. The purpose of this study was to examine the association between muscular strength and residual-specific mortality among a national sample of US adults, which has yet to be investigated. Here, residual-specific mortality is identified as deaths not inclusive of the 9 leading causes of death as identified by the International Classification of Diseases, 10th revision. METHODS: Data from the 1999-2002 National Health and Nutrition Examination Survey were used (N = 2171 adults, aged 50-85 y)...

BACKGROUND: Poor adaptive learning behaviors (ie, distractibility, inattention, and disruption) are associated with behavior problems and underachievement in school, as well as indicating potential attention-deficit hyperactivity disorder. Strategies are needed to limit these behaviors. Physical activity (PA) has been suggested to improve behavior in school-aged children, but little is known about this relationship in preschoolers. This study examined the effects of a PA intervention on classroom behaviors in preschool-aged children...

BACKGROUND: Few studies have quantified cardiorespiratory fitness among individuals seeking bariatric surgery. Treadmill testing allows researchers to determine exercise capacity through metabolic equivalents. These findings can assist clinicians in understanding patients' capabilities to carry out various activities of daily living. The purpose of this study was to determine exercise tolerance and the variables associated with fitness, among individuals seeking bariatric surgery. METHODS: Bariatric surgery candidates completed submaximal treadmill testing and provided ratings of perceived exertion...
