Aging induces a step-like change in the motor ability structure of athletes

Figure 4. Statistically significant decrease in performance with increase in age. (A) and (B) show 100m, 400m, and 1500m run performance in speed and record times across nine age groups. The circle and the bar denote the mean and the mean ± standard deviation. Analysis of variance (ANOVA) demonstrates significant differences between all pairs of neighboring age groups in all three events, except only two pairs in the 1500m run.
