Effects of age and experience on physical activity accumulation during kin-ball.

摘要

In 2008, the U.S. Department of Health & Human Services (USDHHS) released a document titled Physical Activity Guidelines for Americans (USDHHS, 2008). These guidelines suggest that children accrue at least 60 min or more of physical activity daily (most of which should be either moderate- or vigorous-intensity aerobic physical activity) and adults achieve at least 150 min/week of moderate-intensity (or 75 min/week of vigorous-intensity) aerobic physical activity.Concurrent with these recommendations, increasing emphasis has been placed on the development of comprehensive school physical activity programs that encompass physical activity programming before, during, and after the school day (National Association for Sport and Physical Education, 2003). Even the federal government passed legislation (PL 108-265) that requires all districts with federally funded school meal programs to develop and implement wellness policies.

As an executive summary, the following key points are notable.
