Stride length, hip, knee and ankle angles were compared during barefoot and shod running on a treadmill at two speeds. Nine well-trained (1500m time: 3min: 59.80s +/- 14.7 s) male (22 +/- 3 years; 73 +/- 9 kg; 1.79 +/- 0.4 m) middle distance (800 m - 5,000 m) runners performed 2 minutes of running at 3.05 m.s(-1) and 4.72 m.s(-1) on an treadmill. This approach allowed continuous measurement of lower extremity kinematic data and calculation of stride length. Statistical analysis using a 2X2 factorial ANOVA revealed speed to have a main effect on stride length and hip angle and footwear to have a main effect on hip angle. There was a significant speed*footwear interaction for knee and ankle angles. Compared to shod running at the lower speed (3.05 m.s(-1)), well trained runners have greater hip, knee and ankle angles when running barefoot. Runners undertake a high volume (similar to 75%) of training at lower intensities and therefore knowledge of how barefoot running alters running kinematics at low and high speeds may be useful to the runner.
