We aimed to evaluate the internal consistency and factor structure of Functional Movement Screen (FMSTM) in youth athletes quantify differences between individual task score at different stages maturation. FMSTM anthropometric variables were measured 144 (96 female, 48 male). Biological maturation was categorised as before- (<-0.5 years), at- (−0.49–0.50 years) after- peak height velocity [PHV] (>0.51 years). Internal poor (Cronbach's alpha; 0.53, ±90% confidence limit 0.10; ordinal alpha 0.6, ±0.09). Principle component analysis extracted two components, representing 47% total variance. Tasks loading highest on 1 required stability, while those 2 favoured mobility. "Likely" decrements tasks observed before-PHV. In-line lunge (effect size limit; −0.47, ±0.49), hurdle step (−0.38, trunk stability push-up (−0.51, ±0.45), lower compared with at-PHV rotatory (−0.44, ±0.37) than after-PHV. Boys' scored "most likely", higher (0.73, ±0.28) push-up, girls "likely" shoulder mobility (0.46, ±0.29). In our population, is not uni-dimensional, thus should be avoided. Clear affects tasks.
