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 .
Adiposity, aerobic fitness, muscle fitness, and markers of inflammation in children.
PURPOSE The purpose of this study was to describe levels of inflammation markers in Norwegian children and to examine the associations of adiposity , aerobic fitness , and muscle fitness with markers of inflammation . METHODS In 2005 - 2006 , 1467 nine-year-olds were r and omly selected from all regions in Norway . The participation rate was 89 % . The inflammatory markers evaluated included C-reactive protein ( CRP ) , leptin , adiponectin , plasminogen activator inhibitor-1 , tumor necrosis factor-α , hepatocyte growth factor , resistin , and interleukin-6 . We assessed muscular strength by measuring  explosive , isometric , and endurance strength . Aerobic fitness was measured directly during a maximal cycle ergometer test .  Adiposity was expressed as waist circumference ( WC ) . RESULTS The girls had significantly higher levels of CRP , leptin , adiponectin , and resistin and lower levels of tumor necrosis factor-α compared with the boys . We observed a grade d association of CRP and leptin levels across quintiles of WC , aerobic fitness , and muscle fitness ( P ≤ 0.001 for all participants ) . The regression analyses revealed that WC , aerobic fitness , and muscle fitness were independently associated with the CRP ( WC β = 0.158 , P < 0.001 ; aerobic fitness β = -0.190 , P < 0.001 ; muscle fitness β = -0.122 , P < 0.002 ) after adjustments for sex , age , Tanner pubertal stage , and the other independent variables . The same pattern was observed for leptin levels ( WC β = 0.406 , P < 0.001 ; aerobic fitness β = -0.298 , P < 0.001 ; muscle fitness β = -0.064 , P < 0.036 ) . CONCLUSIONS These data represent a reference material with respect to inflammatory markers . Our results show that adiposity , aerobic fitness , and muscle fitness were independently associated with the CRP and leptin levels
