Abstract

The main muscle groups in the non-terminal straight line were gastrocnemius muscle, biceps femoris muscle, lateral femoris muscle and medial femoris muscle; The range of the main muscle groups during the entire cushioning and thrusting and extension phases is very stable. The cushioning phase is the gastrocnemius, biceps femoris, tibial anterior muscle, and lateral femoris; the thrusting and extension phases are the medial femoris, lateral femoris, and biceps femoris, Gastrocnemius; Rhythm has no significant difference in the MPF of each muscle group in the non-end-point straight and the end-point straight (P>0.05), and the MPF of each muscle group in the end-point straight has a downward trend.
