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 .
Relationships between physical activity and physical capacity in adolescent females and bone mass in adulthood.
This study investigates whether physical activity and physical performance in adolescence are positively related to  adult bone mineral density ( BMD ) . In 1974 , physical activity , endurance , and muscular strength were measured in 204 r and omly selected female students , age 16.1 + /- 0.3 year ( range 15 - 17 years ) . Twenty years later , 36 of the women volunteered to undergo a measurement of their BMD . Women who were members in a sports club in adolescence had significantly higher adult BMD ( mean differences of 5 % to 17 % depending on site ) compared with subjects who were not engaged in a sports club . Furthermore , women with persistent weight-bearing activity in adulthood had significantly higher BMD compared with women who had stopped being active or had never been active . The differences ranged between 5 % and 19 % with the highest difference found in trochanter BMD . Stepwise regression analyses showed that membership in a sports club at baseline was a significant independent predictor of BMD in the total body , lumbar spine , legs , trochanter , and femoral neck , explaining 17 - 26 % of the variation in BMD . Change in body weight was a strong independent predictor of BMD of the total body and arms , explaining 8 % of the variation in both sites . In addition , running performance at baseline was an independent predictor of total body BMD , whereas the two-h and lift performance significantly predicted BMD of the total body , legs and trochanter . The hanging leg-lift and h and grip were both significant predictors of arm BMD . In conclusion , membership in a sports club and site-specific physical performance in adolescence together with the change in body weight were significantly associated with adult BMD in premenopausal women
