Foot Angular Range (Foot AR)
Foot Angular Range measures how much the heel moves up and down while pedaling.
- Looking at the right and left Foot AR values provides insight to left/right movement imbalances.
The Foot Angular Range is calculated by subtracting the angle of the foot at its lowest point from its highest point. This score is mainly used for characterizing an athlete’s pedaling. The bigger the Foot Angular Range, the higher the heels rise during the 9 - 12 o’clock phase, and the more that ankling occurs between 0 - 6 o’clock.
The up-to-down angular range of the foot (with the pedal as the vertex) along a pedaling stroke, in degrees. The lower the range, the easier it is for the leg to transfer power to the pedal.
Range: 0° - 90°
Foot Angular Range Q1 (Foot AR Q1)
Foot Angular Range (Q1) shows the foot angular range of the first quadrant of the pedaling cycle - 12 o’clock to 3 o’clock position.
- Looking at the right and left Foot AR (Q1) values provides insight to left/right movement imbalances.
A large FAR Q1 shows that the cyclist pushes down hard after the 12 o’clock position, creating a thrust around the 1 and 2 o’clock positions. By pushing down earlier near the 12 o’clock position, the cyclist minimizes the total angle the foot shifts between the 12 - 3 o’clock position.
Foot Angular Range (Q1) measures the range of angular movement that occurs between the 12 and 3 o’clock position. The higher the range, the longer the delay for the “push down” motion to start for the power phase.
Range: 0° - 90°
