1. Applied Biomechanics GAIT ANALYSIS

2. If we analyze the gait what plane is the person walking? Looking at the right leg, we can label each part of the gait along with phases. Footstrike Eccentric Stance/Support Isometric Toe Off Concentric Swing Concentric Footstrike Eccentric

7.  Running has different phases than walking does  Footstrike Phase  Toe off Phase  Swing Phase  Stance/Support Phase  Floating Phase  Bracket where you think these phases are and label the phase along with the phase that is generated during the motion (eccentric, concentric, isometric) RUNNING

9.  Stride length increases w/speed  Stride frequency increases w/speed  Swing phase longer when running  Stance phase longer when walking  Airborne during running; one point of contact maintained when walking WALKING VS. RUNNING
