The answer to this question is “yes,” according to results of a study in 306 youngsters aged 9 to 17 years, which showed a link between increased after-school time spent outdoors and a boost in moderate-to-vigorous physical activity and its related health benefits.
The answer to this question is “yes,” according to a study in 306 youngsters aged 9 to 17 years, which showed a link between increased after-school time spent outdoors and a boost in moderate-to-vigorous physical activity and its related health benefits.
The study was conducted in the winter and spring terms of the 2008-2009 academic school year. Participants completed a questionnaire about how much time they spent outdoors after school during a 7-day period and wore waist-mounted accelerometers for a similar length of time to determine their activity level. Among all participants, 17% reported spending no time outdoors after school; 44% said they spent some time outdoors; and 39% reported spending most or all after-school time outdoors.
Moderate-to-vigorous physical activity increased along with the amount of time reported spent outdoors, and sedentary activity decreased commensurately. In addition, youngsters who spent most or all after-school time outdoors had greater cardiorespiratory fitness, although investigators saw no differences across the groups in overweight/obesity or blood pressure levels (Schaefer L, et al. J Pediatr. 2014;165:516-521).
