Asymmetries in lean mass, balance, and stability in 12-year-old female soccer (football) players: a cross-sectional study

While lean mass and landing performance were symmetrical, the anterior reach asymmetry may reflect early neuromuscular differences. These results suggest that asymmetries in young female players may begin to emerge in select functional domains, even in the absence of structural or kinetic differences. Ongoing monitoring during adolescence may help clarify how training exposure and development influence these patterns.
