Aging induces a step-like change in the motor ability structure of athletes
Figure 1. The change in loading patterns. (A) shows the factor loadings for the first and the second principal components (PCs) and proportions of variance explained by the PCs. Colors are assigned to loadings ≥ 0.5. Four different colors indicate four categories classified according to the loading pattern. (B) shows how each factor loading changes as the age increases. Flipping occurs around the age of 50.
