Results Physical activity was associated with numerous health benefits .
The dose-response relations observed in observational studies indicate that the more physical activity , the greater the health benefit .
Results from experimental studies indicate that even modest amounts of physical activity can have health benefits in high-risk youngsters ( e.g. , obese ) .
Vigorous intensity activities may provide even greater benefit .
Aerobic-based activities had the greatest health benefit , other than for bone health , in which case high-impact weight bearing activities were required .
Some of the health benefits can be achieved through an average of 30 minutes per day . [

Background The purpose was to : 1 ) perform a systematic review of studies examining the relation between physical activity , fitness , and health in school-aged children and youth , and 2 ) make recommendations based on the findings .
Active transportation to school over 2 years in relation to weight status and physical activity.
OBJECTIVE To prospect ively examine potential benefits of active commuting to school on measures of weight status and physical activity in a sample of youth . RESEARCH METHODS AND PROCEDURES A cohort of students from seven elementary schools was measured four times -- in the fall and spring of fourth grade ( N = 1083 ) and fifth grade ( N = 924 ) . Participants were classified as active ( walking , biking , or skateboarding to school almost every day for baseline analyses or at least 2 d/wk for analyses of consistent active commuting ) or non-active commuters to school . Accelerometers were used to measure physical activity . Height , weight , and skinfolds were objective ly assessed . RESULTS Boys who actively commuted to school had lower BMI ( p < 0.01 ) and skinfolds ( p < 0.05 ) than non-active commuters to school in the fourth grade . Active commuting to school over 2 years was not associated with BMI change or overweight status . DISCUSSION Walking and cycling to school may contribute to preventing excessive weight gain , or leaner children may walk or cycle to school
