Certified Personal Trainer (NSCA) Practice Exam

What represents a correct body position on a stationary bicycle?

1. With the ball of the foot on the upward pedal, the knee is above the height of the hips

2. With the heel of the foot on the downward pedal, the leg is straight

3. With the heel of the foot on the upward pedal, the knee is even with the height of the hips

4. With the ball of the foot on the downward pedal, the leg is straight

The correct answer is: With the heel of the foot on the downward pedal, the leg is straight

When using a stationary bicycle, proper body positioning is crucial for both efficiency and to prevent injury. The most appropriate position occurs when the heel of the foot is on the downward pedal, and the leg is straight. This position allows for optimal power transfer during the pedal stroke and promotes proper biomechanics. Having the leg straight at the lowest point of the pedal stroke ensures that the knee is not overextended and aligns with the natural range of motion. This alignment minimizes strain on the knee joint and allows for effective engagement of the quadriceps and hamstrings throughout the cycling motion. It also helps maintain a balanced posture over the pedals, encouraging overall stability while cycling. The other options present positions that could cause potential discomfort or risk of injury. For example, if the knee is positioned above the height of the hips, it could lead to excessive strain on the joints. Similarly, having the ball of the foot on the downward pedal can compromise stability and overall pedaling efficiency, as it shifts the weight distribution in a less effective manner. Thus, the proper technique of having the heel on the downward pedal while keeping the leg straight ensures that the cyclist is positioned to utilize their strength effectively and safely.
