BENEFICIAL KINETIC ADAPTATIONS AFTER ENDURANCE TRAINING
Keywords: running adaptation, endurance training, iliotibial band, patellofemoral contact force
AbstractEndurance training produces adaptations in running kinetics, although it does not produce changes in kinematics. We performed a prospective study of 23 runners who joined established marathon training teams. Each was tested in their first month of training and again two weeks prior to their marathon. The approximate time between tests was three months. Four peak ground reaction forces were reduced significantly after the training: lateral (15.4%), acceleration (7.10%), vertical (2.1%) and the normalized resultant (2.1%). Kinetic variables associated with iliotibial band injuries and anterior knee pain also had significant reductions. Peak hip adduction moments were reduced by 6.0%, peak patellofemoral contact force was reduced by 7.6%.
