The Claim
In children and adolescents aged 5–18 years, pubertal stage is an independent predictor of handgrip strength, with handgrip strength increasing significantly across pubertal stages after adjustment for body composition and physical activity.
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 teenagers aged 5 to 18, handgrip strength increases as they progress through puberty, even when accounting for differences in body size and physical activity levels.
See the scientific wording
In children and adolescents aged 5–18 years, pubertal stage is a strong independent predictor of handgrip strength, with strength increasing significantly through puberty, even after adjusting for body composition and physical activity.
As children enter puberty, their bodies produce more sex hormones, which cause muscles to grow larger and stronger by making more protein inside muscle cells. These hormones also improve how well the brain sends signals to muscles, making each muscle contraction more powerful. This happens even if the child’s body size or activity level stays the same.
What the research says
1 studyAs kids grow through puberty, their hand strength gets stronger — not just because they get bigger or exercise more, but because their bodies are changing naturally. This study found that puberty itself is a key reason for stronger hands, even when accounting for how much muscle or fat they have.
