Abstract

This study investigated the associations between the running speeds corresponding to deflection points in biomechanical parameters and the speed at the anaerobic threshold. Fifteen male recreational runners participated, running on a treadmill with gradual speed increases until perceived exhaustion. The anaerobic threshold was measured using a spiroergometry device, and kinematic data were recorded by four inertial sensors on their shanks and trunk. Stepwise regression analysis indicated that the running speeds at the deflection points of angular velocity of thorax rotation and peak tibial acceleration were the most effective predictors of the speed at the anaerobic threshold (adjusted R² = 0.65). The running speed at a kinematic deflection point proves to be an effective predictor of anaerobic threshold speed, providing a valuable tool for tailoring training intensities.
