Figure 1. Performing Nordic Hamstring exercise while using an incline platform. Each figure shows ICL50 (a), ICL30 (b), ICH50 (c), and ICH30 (d). The knee joint angle and trunk angle compared to the arbitrary horizontal line are shown in each figure. Note: Thin and trunk angles compared to the ground differ among subjects because of the difference in subjects’ length of foot and tibia while the difference was very small.
