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 . [

Effects of school-based aerobic exercise on blood pressure in adolescent girls at risk for hypertension.
OBJECTIVES This study evaluated the effects of aerobic exercise physical education on blood pressure in high-risk , predominantly African-American , adolescent girls . METHODS Ninth- grade girls ( n = 99 ) with blood pressure above the 67th percentile were r and omized to 1 semester of aerobic exercise classes or st and ard physical education classes . RESULT The study was completed by 88 girls . At posttest , only members of the aerobic exercise group increased their estimated cardiorespiratory fitness . The aerobic exercise group had a greater decrease in systolic blood pressure than the st and ard physical education group ( P < .03 ) . CONCLUSIONS Aerobic exercise physical education is a feasible and effective health promotion strategy for high-risk adolescent girls
