There was some evidence that school-based physical activity interventions had a positive impact on four of the nine outcome measures .
Specifically positive effects were observed for duration of physical activity , television viewing , VO2 max , and blood cholesterol .
Generally , school-based interventions had little effect on physical activity rates , systolic and diastolic blood pressure , BMI , and pulse rate .
At a minimum , a combination of printed educational material s and changes to the school curriculum that promote physical activity result ed in positive effects .
Few changes in outcomes were observed in this up date with the exception of blood cholesterol and physical activity rates .
For example blood cholesterol was no longer positively impacted upon by school-based physical activity interventions .
The evidence suggests the ongoing implementation of school-based physical activity interventions at this time , given the positive effects on behavior and one physical health status measure .
BACKGROUND The World Health Organization ( WHO ) estimates that 1.9 million deaths worldwide are attributable to physical inactivity and at least 2.6 million deaths are a result of being overweight or obese .
In addition , WHO estimates that physical inactivity causes 10 % to 16 % of cases each of breast cancer , colon , and rectal cancers as well as type 2 diabetes , and 22 % of coronary heart disease and the burden of these and other chronic diseases has rapidly increased in recent decades .
OBJECTIVES The purpose of this systematic review was to summarize the evidence of the effectiveness of school-based interventions in promoting physical activity and fitness in children and adolescents .
The Impact of a 12-Week Resistance Training Program on Strength, Body Composition, and Self-Concept of Hispanic Adolescents
Velez , A , Golem , DL , and Are nt , SM . The impact of a 12-week resistance training program on strength , body composition , and self-concept of Hispanic adolescents . J Strength Cond Res 24(4 ) : 1065 - 1073 , 2010-Current evidence suggests that a resistance training program may be physically and psychologically beneficial for adolescents . The purpose of this study was to examine the effects of a structured resistance training program on strength , body composition , and self-concept in normal and overweight Hispanic adolescents . Male and female participants ( n = 28 ; 16.1 ± 0.2 y ; 164.5 ± 1.4 cm ; 63.3 ± 2.5 kg ; 20.0 ± 1.7 % body fat [ BF ] ) were recruited from a predominantly Hispanic high school . Prior to the 12-week program , strength , body composition , and self-concept were assessed . Subjects were r and omly assigned to a control group ( CON ; n = 15 ) or to a resistance training group ( RT ; n = 13 ) that participated in supervised strength training 3 days/week . All measures were repeated at the end of the 12-week program . RT had significantly greater strength increases for bench press ( p < 0.001 ) , seated row ( p = 0.002 ) , shoulder press ( p < 0.001 ) , and squats ( p = 0.002 ) . RT had significant reductions in % BF ( p = 0.001 ) , whereas CON had slightly increased % BF . RT had an increase in condition/stamina competence ( p = 0.008 ) , attractive body adequacy ( p = 0.017 ) , and global self-worth ( p = 0.013 ) from pretest to posttest , whereas no change was observed for CON . In conclusion , resistance training result ed in significant physiological and psychological improvements in Hispanic adolescents compared to typical school-based activities . These findings indicate that resistance training can be incorporated into the activities of Hispanic adolescents to promote improved health and fitness
