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 .
Muscular strength in male adolescents and premature death: cohort study of one million participants
Objectives To explore the extent to which muscular strength in adolescence is associated with all cause and cause specific premature mortality ( < 55 years ) . Design Prospect i ve cohort study . Setting Sweden . Participants 1 142 599 Swedish male adolescents aged 16 - 19 years were followed over a period of 24 years . Main outcome measures Baseline examinations included  knee extension , h and grip , and elbow flexion strength tests  , as well as measures of  diastolic and systolic blood pressure and body mass index . Cox regression was used to estimate hazard ratios for mortality according to muscular strength categories ( tenths ) . Results During a median follow-up period of 24 years , 26 145 participants died . Suicide was a more frequent cause of death in young adulthood ( 22.3 % ) than was cardiovascular diseases ( 7.8 % ) or cancer ( 14.9 % ) . High muscular strength in adolescence , as assessed by knee extension and h and grip tests , was associated with a 20 - 35 % lower risk of premature mortality due to any cause or cardiovascular disease , independently of body mass index or blood pressure ; no association was observed with mortality due to cancer . Stronger adolescents had a 20 - 30 % lower risk of death from suicide and were 15 - 65 % less likely to have any psychiatric diagnosis ( such as schizophrenia and mood disorders ) . Adolescents in the lowest tenth of muscular strength showed by far the highest risk of mortality for different causes . All cause mortality rates ( per 100 000 person years ) ranged between 122.3 and 86.9 for the weakest and strongest adolescents ; corresponding figures were 9.5 and 5.6 for mortality due to cardiovascular diseases and 24.6 and 16.9 for mortality due to suicide . Conclusions Low muscular strength in adolescents is an emerging risk factor for major causes of death in young adulthood , such as suicide and cardiovascular diseases . The effect size observed for all cause mortality was equivalent to that for well established risk factors such as elevated body mass index or blood pressure
