Start and Acceleration error: 90 degrees knee angle of front leg not achieved. What is the cause?

Start and Acceleration error: 90 degrees knee angle of front leg not achieved. What is the cause?

• A. Hips too high or low.
• B. Arms too light.
• C. Foot too far forward.
• D. Back knee too straight.

Answer: (A)

The front knee reaching about 90 degrees depends on the height and angle of your hips relative to the leg. If the hips sit too high, you’re more upright, and the front leg can’t flex enough to land at a 90-degree knee bend. If the hips are too low, the chest/torso position changes in a way that also prevents the front knee from hitting that 90-degree angle. So hip position controls this angle during start and acceleration. The other options don’t directly set the front knee angle: arm intensity affects propulsion and balance, foot position affects load and stability, and the back knee’s straightness relates to the rear leg, not the front knee angle.
