Fatigue-related changes in running technique and mechanical variables after a maximal incremental test in recreational runners: a cross-sectional study

Understanding the changes in running mechanics caused by fatigue is essential to assess its impact on athletic performance. Changes in running biomechanics after constant speed conditions are well documented, but the adaptive responses after a maximal incremental test are unknown. We compared the spatiotemporal, joint kinematics, elastic mechanism and external work parameters before and after a maximal incremental treadmill test.
