TABLE 1.
K-means clustering variables definitions.
| Variables | Definitions |
|---|---|
| Kinetic measures | |
| Braking RFD (N/s) | Difference in newtons from the end of braking to the start of braking divided by the duration of the braking phase |
| Braking net impulse (N.s) | Impulse above system weight during braking phase |
| Propulsive net impulse (N.s) | Impulse above system weight during propulsive phase |
| Peak relative propulsive power (W/kg) | Peak power during propulsive phase divided by kg of subject mass |
| Kinematic measures | |
| Braking phase (s) | Duration of braking phase |
| Propulsive phase (s) | Duration of propulsive phase |
| Max hip flexion (degrees) a | Max flexion angle between pelvis and femur during loading phase |
| Max knee flexion (degrees) a | Max flexion angle between femur and tibia during loading phase |
| Max ankle flexion (degrees) a | Max flexion angle between tibia and foot during loading phase |
| Dynamic valgus (degrees) a | Measure of knee deviation from the leg Plane, which is defined using the positions of hip and ankle joint centers and the pelvis anterior direction |
a
Markerless Motion Capture variables are from the start of the movement to the pelvis reaching minimum height; Force plate variables are described in Figure 1.
