Table 2 The means (±standard deviations) for the ratio of 40 km to 8 km of each kinematic variable. It is important to remember that these ratios involve kinematic data that were normalized to the running speed at the corresponding mile marker. This normalization process altered the direction of change, relative to the raw data that is presented in .
