The aim of this study was to investigate the effect of exercise-induced fatigue on vertical ground reaction force and loading rate during crossover landing. To do so, 15 healthy men participated in this study. Peak and landing values of ground reaction forces (GRFs), time to reach them and loading rate in participants before and after were extracted using Kistler force plate. Results showed that the amplitude of the second vertical peak in force (Fz2) (landing GRFs) reduced at toe contact with the ground but the amplitude of the fourth vertical peak in force (Fz4) (landing GRFs) increased at heel contact with the ground. In the fatigued conditions, subjects had faster time to peak of FZ4. Changing the components of GRF and the time to peak of faster to vertical GRF when contacting feet with your ground as a risk factor in the jump or landing. Therefore, providing strategies for preventing this risk factor can play a very important role. Thus, it is suggested that feedback due to changes in these biomechanical parameters complement the treatment and prevention of these risk factors in the activity and rehabilitation of therapists, physiotherapists and other groups.
