Dagens #fsvoversigt:
The health benefits of muscular fitness for children and adolescents: a
systematic review and meta-analysis.
Sports Med. 2014 Sep;44(9):1209-23

Abstract
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.
METHODS: A systematic search of six electronic databases (PubMed, SPORTDiscus,
Scopus, EMBASE, PsycINFO and OVID MEDLINE) was performed on the 20th May, 2013.
Cross-sectional, longitudinal and experimental studies that quantitatively
examined the association between MF and potential health benefits among
children and adolescents were included. The search yielded 110 eligible
studies, encompassing six health outcomes (i.e., adiposity, bone health,
cardiovascular disease [CVD] and metabolic risk factors, musculoskeletal pain,
psychological health and cognitive ability). The percentage of studies
reporting statistically significant associations between MF and the outcome of
interest was used to determine the strength of the evidence for an association
and additional coding was conducted to account for risk of bias. Meta-analyses
were also performed to determine the pooled effect size if there were at least
three studies providing standardised coefficients.
RESULTS: Strong evidence was found for an inverse association between MF and
total and central adiposity, and CVD and metabolic risk factors. The pooled
effect size for the relationship between MF and adiposity was r = -0.25 (95% CI
-0.41 to -0.08). Strong evidence was also found for a positive association
between MF and bone health and self-esteem. The pooled effect size for the
relationship between MF and perceived sports competence was r = 0.39 (95% CI
0.34-0.45). The evidence for an association between MF and musculoskeletal pain
and cognitive ability was inconsistent/uncertain. Where evidence of an
association was found, the associations were generally low to moderate.
CONCLUSION: The findings of this review highlight the importance of developing
MF in youth for a number of health-related benefits.
