The Claim
In children and adolescents aged 5–18 years, a higher body fat percentage is independently associated with lower relative handgrip strength, after adjustment for age, sex, pubertal stage, physical activity, and fat-free mass.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Children and adolescents with higher body fat tend to have lower handgrip strength relative to their body weight, even when accounting for age, sex, puberty, activity level, and lean body mass.
See the scientific wording
In children and adolescents aged 5–18 years, higher body fat percentage is independently associated with lower relative handgrip strength (handgrip strength divided by body weight), even after adjusting for age, sex, pubertal stage, physical activity, and fat-free mass, suggesting that excess adiposity may impair muscle function relative to body size.
Extra fat in the body releases chemicals that disrupt muscle function and cause fat to build up inside muscles, making them weaker for their size.
What the research says
1 studyKids and teens with more body fat tend to be weaker for their size, even if they have the same amount of muscle as others — meaning extra fat might make muscles work less efficiently.
