Table 3 significances (p < 0.05) between muscle forces of different split squats with different step lengths (55%, 70% and 85% of participant’s leg length) and tibial angles (60°, 75° and 90° tibial angle relative to ground)

  1. Quadriceps (quad), including m. vastus lateralis (vl), m vastus intermedius (vi), m. vastus medialis (vm) and M. rectus femoris (rf); Hamstrings (ham) including m. biceps femoris short head (bs), m. biceps femoris long head (bl), m. semimembranosus (sm) and m. semitendinosus (st); m. gluteus maximus muscles (glut), including three different parts, the lateral part (lp), the intermedial part (ip), and the medial part (mp) were examined. Interactions were observed between mp of the front limb and vi, sm, st, lp, ip and mp of the rear limb
