Figure 5. Linear decrease in performance with increase in age. (A) and (B) show the age-dependent linear decreases in speed and the linear increases in record times, respectively. The R2 values for the regression of the both variables on age are all high, but the regression of speed on age shows higher R2 values for all three events.
