Running Gait Flashcards
how does stance phase (support) of running gait differ to that of walking gait
one foot or the other, never both
how does swing phase (recovery) of running gait differ to that of walking gait
one foot is off the ground, sometimes both - double swing or float phase
what happens to the base of gait as running speed increases
it narrows - sometimes called runners varus
what affect will greater speed have
- greater hip flexion
- greater knee flexion
- greater anterior trunk lean
- greater proportion of float duration
- reduced support phase
runners tend to fall into one of 3 types of foot strike
- heel striker
- mid-foot striker
- forefoot striker
impact forces in running gait:
* contact phase
* late midstance into propulsion
* compressive force
- contact phase: 2 x BW
- late midstance into propulsion: 3 x BW
- compressive force: upto 10 x BW
