Study Notes

Changes occur in motion requirements and timing of activity as locomotion speed increases.
Running requires eccentric muscle activity to absorb impact forces and generate power.
Muscle activity is greater and onset timing is sooner in running compared to walking.
Gluteus maximus maintains the same output and timing in both walking and running.
Gluteus medius output amplitude increases with running speed.
Hip flexors propel the hip into flexion during the initial swing phase.
Adductor muscle activity is different in running compared to walking.
Adductors work eccentrically to stabilize the body during midstance and midswing in running.
Hip adductors are active throughout the entire running gait cycle.
Hamstrings' primary function during running occurs at the hip.
