Biomechanical analysis of SFMA squat movements, including events, phases, and discrete metrics.
Metric | Data Type | Description |
---|---|---|
Initiation | Int | the start of the squat |
Descent Start | Int | the start of downward movement |
Bottom | Int | the instant of maximum squat depth |
Bottom1 | Int | the first instance of maximum squat depth |
Ascent Start | Int | the start of upward movement |
End | Int | the end of the movement |
Phase | Stage | Start | End | Event or Phase |
---|---|---|---|---|
Preparation | Setup | Initiation | Descent Start | Phase |
Descent | Eccentric | Descent Start | Bottom | Phase |
Ascent | Concentric | Bottom | End | Phase |
Metric | Data Type | Units | Description |
---|---|---|---|
Depth | Float | meters | Vertical displacement of pelvis from start to bottom |
Maximum Trunk Angle | Float | degrees | Maximum trunk angle relative to vertical |
