Krachttraining verlaagt het vetpercentage van kinderen
Er was weliswaar een trend dat krachttraining de vetmassa verlaagde, maar dat effect was niet significant. Er was ook een trend dat krachttraining de vetvrije massa vergrootte, maar ook die was niet significant.
"Overall, this meta-analysis found a small, statistically significant effect of resistance training interventions on body fat percent and skinfolds, but no overall significant effect on body mass, BMI, fat free mass, fat mass, lean mass or waist circumference. While we can conclude that resistance training interventions have a small positive impact on some indicators of weight status, it is noted that this reflects only a small body of published work."
"With resistance training interventions offering potential benefits for youth with regards to weight status, it is imperative that more robust and quality studies should be conducted to further, and unequivocally, investigate the role resistance training may play in the treatment and prevention of obesity."
"Based on the findings of this meta-analysis, and in support of the conclusions of previous reviews, future studies should be designed as randomised controlled trials with large samples and include a treatment group with an isolated RT intervention."
"There should be careful consideration into appropriate intervention content and assessment methods. If validated, this type of intervention, as recommended by the UK and WHO physical activity guidelines, could ultimately have a positive impact on the prevalence of common obesity-related diseases, such as type 2 diabetes, cardiovascular disease and cancer, and improve the health of individuals not only during childhood but as they progress through life."
