  4. b) Muscular functions: 1-Gluteus Maximus: Prevent jack-knifing of hip i.e. excessive hip flexion) and anterior pelvic tilt. 2-Quadriceps: In Early stance prevent jack-knifing of knee. In Late stance: eccentrically to control knee flexion degree 3-Hamstring: In stance: Support back of knee against extension moment of GRFV. In swing: *Assist knee flexion in IS. *Decelerates tibial shank in TS

  5. 4-Ankle dorsi flexors: In Stance*control forefoot lowering. *After forefoot contacts floor- pull tibia forward over foot. In Swing phase: *lift toe up so prevent toes from dragging on ground. *functionally shorten swinging limb. 5-Calf muscles: controls dorsi flexion degree ecentrically in MS and TS. Then contract concentrically to planter flex ankle joint in PS G. Medius: in mid stance to prevent contra-lateral (swinging) hip from dipping greater than 5 – 80

  6. It worth noting that at most joints, the motion occurring during the concentric contraction continues after the contraction ceases. For example the hip continues to extends long after beak activities of gluteus maximus and hamstrings, thus the chief function of the lower extremity during locomotion are to slow one motion and to provide an initial burst or pull, in the opposite direction.
