Results Strong evidence was found for an inverse association between MF and total and central adiposity , and CVD and metabolic risk factors .
Strong evidence was also found for a positive association between MF and bone health and self-esteem .
Conclusion The findings of this review highlight the importance of developing MF in youth for a number of health-related benefits
Background Physical fitness during childhood and adolescence has been identified as an important determinant of current and future health status .
While research has traditionally focused on the association between cardio-respiratory fitness and health outcomes , the association between muscular fitness ( MF ) and health status has recently received increased attention .
Objective The aim of this systematic review and meta- analysis was to evaluate the potential physiological and psychological benefits associated with MF among children and adolescents .
Effects of resistance training on insulin sensitivity in overweight Latino adolescent males.
PURPOSE Insulin resistance is thought to be a core defect in the pathophysiology of obesity-related comorbidities in children , such as type 2 diabetes . Exercise training is known to improve insulin resistance and reduce the risk of type 2 diabetes in adults . However , very little is known regarding the effects of exercise on insulin resistance in youth . Therefore , we examined the effects of a 16-wk resistance training exercise intervention on insulin sensitivity in youth at high risk for developing type 2 diabetes . METHODS Twenty-two overweight Latino adolescent males were r and omly assigned to either a twice-per-week resistance training group ( RT=11 ) or a nonexercising control group ( C=11 ) for 16 wk . Strength was assessed by one-repetition maximum , body composition was quantified by dual-energy x-ray absorptiometry , and insulin sensitivity was determined by the frequently sample d intravenous glucose tolerance test with minimal modeling . RESULTS Significant increases in upper- and lower-body strength were observed in the RT compared with the C group . The RT group significantly increased insulin sensitivity compared with the C group ( P<0.05 ) , and this increase remained significant after adjustment for changes in total fat mass and total lean tissue mass ( P<0.05 ) . Compared with baseline values , insulin sensitivity increased 45.1+/-7.3 % in the RT group versus -0.9+/-12.9 % in controls ( P<0.01 ) . CONCLUSION A twice-per-week 16-wk resistance training program can significantly increase insulin sensitivity in overweight Latino adolescent males independent of changes in body composition
