No Change in Executive Function or Stress Hormones Following a Bout of Moderate Treadmill Exercise in Preadolescent Children.

Several studies suggest that acute bouts of exercise improve executive function in preadolescent children. However, the mechanisms underlying these effects are not completely understood. Specifically, no studies have examined the relationship between the stress hormone response to exercise and improvements in executive function in preadolescent children.

Aerobic Fitness Markers Associated with Post-Paddling Breath-hold Capacity in Competitive Surfers.

Competitive surfing is a growing sport with evolving performance and safety demands. One particular challenge surfers face is the need to endure long breath-holds following bouts of surf paddling. The purpose of this study was to examine the association between aerobic fitness markers, such as VO and ventilatory thresholds, and post-paddling breath-hold capacity in competitive surfers.

Feasibility of Integrating Physical Activity Into Early Education Learning Standards on Preschooler's Physical Activity Levels.

Background: For a health behavior intervention to be sustainable within preschool centers, the intervention should be implemented by classroom teachers. Unfortunately, teachers are constrained by demands such as meeting early childhood education standards. Therefore, the purpose of this pilot study was to examine the feasibility and preliminary efficacy of integrating a health behavior intervention into early education learning standards on physical activity (PA), diet, and sleep (PADS) behavior of preschoolers.

Effect of a culturally-tailored mother-daughter physical activity intervention on pre-adolescent African-American girls' physical activity levels.

Positive parent-child attachment can be determined by opportunities for the child to interact with his/her parent and can influence a child's physical activity (PA) behavior. Therefore, an intervention that provides children and their parent more time to interact positively could impact children's PA. We examined the efficacy of a 12-week mother-daughter intervention on African-American girls' PA levels.

Associations among physical activity, screen time, and sleep in low socioeconomic status urban girls.

Insufficient sleep is associated with higher risk of poor health outcomes in low socioeconomic status (SES) urban elementary age girls. Decreased physical activity (PA) and increased screen time may be associated with poor sleep. This study examined if PA and screen time are associated with sleep in girls from a low SES urban community.

Objective Analysis of Preschoolers' Physical Activity Patterns During Free Playtime.

Background: The purpose of this study was to examine the temporal patterns of preschoolers' physical activity (PA) levels during a typical outdoor free playtime.

Methods: Baseline playtime accelerometer counts (4.3 ± 0.
