Conclusion A prospect i ve negative association was observed between muscular fitness in childhood/adolescence and adiposity and cardiometabolic parameters in later life , together with a positive association for bone health .
There is inconclusive evidence for low back pain benefits
Background No previous systematic review has quantitatively examined the association between muscular fitness during childhood and adolescence and health parameters later in life .
Objective The aim was to systematic ally review and meta-analyze the current evidence for a prospect i ve association between muscular fitness in childhood and adolescence and future health status .
Childhood cardiorespiratory fitness, muscular fitness and adult measures of glucose homeostasis.
OBJECTIVES To assess whether childhood cardiorespiratory fitness ( CRF ) and muscular fitness phenotypes ( strength , power , endurance ) predict adult glucose homeostasis measures . DESIGN Prospect i ve longitudinal study . METHODS Study examining participants who had physical fitness measured in childhood ( aged 7 - 15 years ) and who attended follow-up clinics approximately 20 years later  and provided  a fasting blood sample which was tested for glucose and insulin . Physical fitness measurements included muscular strength ( right and left grip , shoulder flexion , shoulder and leg extension ) , power ( st and ing long jump distance ) and endurance ( number of push-ups in 30s ) , and CRF ( 1.6 km run duration ) . In adulthood , fasting glucose and insulin levels were used to derive glucose homeostasis measures of insulin resistance ( HOMA2-IR ) and beta cell function ( HOMA2-β ) . RESULTS A st and ard deviation increase in childhood CRF or muscular strength ( males ) was associated with fasting glucose ( CRF : β=-0.06mmol/L ) , fasting insulin ( CRF : β=-0.73mU/L ; strength : β=-0.40mU/L ) , HOMA2-IR ( CRF : β=-0.06 ; strength : β=-0.05 ) and HOMA2-β ( CRF : β=-3.06 % ; strength : β=-2.62 % ) in adulthood , independent of the alternative fitness phenotype ( all p<0.01 ) . Adjustment for childhood waist circumference reduced the effect by 17 - 35 % for CRF and 0 - 15 % for muscular strength ( males ) and statistical significance remained for all associations expect between CRF , fasting glucose and HOMA2-β ( p>0.06 ) . CONCLUSIONS CRF and muscular fitness in childhood were inversely associated with measures of fasting insulin , insulin resistance and beta cell function in adulthood . Childhood CRF and muscular fitness could both be potential independent targets for strategies to help reduce the development of adverse glucose homeostasis
