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 .
Kinametic variables Ratio of km 40:8 Direction of change
Stride length 1.013 (.038) * 1.3% increase
Contact time 1.131 (.131) * 13.1% increase
Peak knee flexion during support .968 (.095) * 3.2% decrease
Peak hip extension during swing .721 (2.816) * 27.9% decrease
Peak knee flexion during swing 1.043 (.101)* 4.3% increase
Peak hip flexion during swing 1.074 (.183) * 7.4% increase
Significantly greater than Pre.
