The Claim
In children and adolescents aged 5–18 years, absolute handgrip strength is higher in individuals with overweight or obesity than in those with normal weight, and this difference is attributable to greater fat-free mass and body size rather than enhanced muscle function.
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 overweight or obesity have stronger handgrips than those with normal weight, but this is because they have more muscle and larger bodies, not because their muscles are stronger.
See the scientific wording
In children and adolescents aged 5–18 years, absolute handgrip strength is higher in those with overweight or obesity compared to normal-weight peers, but this difference is explained by greater fat-free mass and body size, not improved muscle function.
Children with more body fat have larger muscles because they are bigger, but their muscles are weaker for their size because fat builds up inside the muscles and inflammation slows down how well the muscles work. This means they can grip harder simply because they have more muscle tissue, not because their muscles are stronger.
What the research says
1 studyOverweight kids may squeeze harder with their hands because they’re bigger and have more muscle, but their muscles aren’t actually stronger for their size—in fact, more body fat is linked to weaker muscles when you account for muscle size.
