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

Figure 2. The change in correlation coefficients. The age dependent changes of the correlation coefficient between the speed in 100m run and the speed in 400m run; and the correlation coefficient between the speed in 400m run and the speed in 1500m run are shown. The two correlation coefficients cross around the age of 50.
