Acceleration of the thigh is the action of what muscles?
Iliopsoas and Rectus Femoris
Why is Rectus Femoris important when considering acceleration of the thigh?
Because sprinters can tear this off the anterior inferior spine where it originates. It comes off easily due to cartilaginous apophysis attachment.
Deceleration is accomplished by _____, which come across the hip joint and contract eccentrically (elongating).
Hamstring
Why is the Hamstring important when considering deceleration of the thigh?
Hamstrings are pulled by athletes who decelerate quickly or kick, pulling the muscle off the ischial tuberosity.
Heel Strike fires the _____ eccentrically contracting and lowering the foot to the ground.
_____ eccentrically contract to absorb energy as knee goes into 5 degrees flexion; this prevents the knee from buckling.
Dorsiflexors (Anterior Tibial group, Deep Fibular N.)
Quadriceps
Foot Strike: _____ contract to hold the body up. As center of mass moves forward, the _____ contract to push body ahead.
Abductors Plantar flexors (triceps surae: gastrocs, soleus, plantaris)
Toe Off: _____ concentrically contract to help the plantar-flexors push body ahead by elongating lower limb.
