The Claim
In children and adolescents aged 5–18 years, higher body fat percentage is associated with lower relative handgrip strength after adjustment for fat-free mass index.
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.
In children and adolescents aged 5–18, a higher percentage of body fat is linked to weaker handgrip strength even when accounting for muscle mass.
See the scientific wording
In children and adolescents aged 5–18 years, body fat percentage remains a negative predictor of relative handgrip strength even after adjusting for fat-free mass index, suggesting that adiposity may impair muscle performance beyond its effect on lean mass.
Extra body fat releases chemicals that disrupt muscle function and cause fat to build up inside muscles, making them less able to generate force even when muscle size is normal.
What the research says
1 studyEven when kids have the same amount of muscle as others, those with more body fat tend to have weaker hand strength. This suggests that extra fat might make muscles work less well, even if the muscle itself isn’t weaker.
