Optimizing Pedal Frequency for Cycling: A Scientific Approach

Optimizing Pedal Frequency for Cycling: A Scientific Approach

1. What is Pedal Frequency ?

Pedal frequency refers to the number of times the bicycle pedal rotates per minute on one side, measured in RMMP (Revolutions Per Minute). Research has shown that the optimal pedal frequency range is between 90 and 100 revolutions per minute. In this range, the torque on the leg joints and muscle tension are minimized, resulting in the least energy loss. When the pedal frequency is too low, the legs require more force to push the pedals, which makes cycling harder. Long-term low pedal frequency can lead to the accumulation of lactic acid, causing post-exercise soreness. On the other hand, if the pedal frequency is too high, the pedaling speed becomes too fast, causing rapid breathing and increased strain on the cardiovascular system.

More importantly, both low and high pedal frequencies can cause injuries, especially to the cartilage of the knee joints. Once knee cartilage is worn, it is difficult to recover and is irreversible. Therefore, maintaining an optimal pedal frequency allows for maximum energy output and ensures efficient cycling with minimal effort.

2. How to Measure Your Pedal Frequency?

During cycling, you can use a cadence meter to accurately measure your pedal frequency. If you do not have a cadence meter, you can use a bike odometer, smartwatch, or other timing devices to count the number of rotations of one pedal in one minute. After measuring your pedal frequency, compare it with the optimal range of 90 to 100 RPM:

  • If your pedal frequency is lower than this range, try increasing your pedal rotations per minute.
  • If your pedal frequency is too high, decrease your pedal rotations per minute.
  • If your pedal frequency is already in the optimal range, great! Keep it up.

3. How to Improve and Train Your Pedal Frequency?

A smooth and efficient pedal frequency is key to becoming an excellent cyclist. When seated on the saddle, the upper body remains steady, while the legs move rapidly and smoothly, without unnecessary movement or bouncing. This is the ideal state of an efficient pedal frequency, which requires constant training to achieve. Here are some tips to improve your pedal frequency:

  1. Choose a Suitable Gear Ratio
    Selecting a smaller gear ratio can make pedaling easier and reduce the resistance that impacts pedal frequency.

  2. Adjust Saddle Height
    Lower your saddle by 3-5mm to reduce the bouncing and rocking of the body when pedaling at high frequencies. Once your body adapts to the higher cadence, gradually adjust the saddle back to its original height, focusing on pulling the pedal back at the lowest point to eliminate dead spots in the pedal stroke.

  3. Use Clipless Pedals and Shoes
    Using clipless pedals and shoes ensures more precise and stable pedal strokes, improving your cadence training efficiency.

  4. High Cadence Training
    During each ride, dedicate a few minutes to high-cadence training. Try pedaling at maximum effort for one minute, resting for one minute, and repeat for 3 to 5 sets. This will help reinforce muscle memory and allow your body to gradually adapt to a higher cadence.

With continuous training, your body will adapt to a higher pedal frequency, leading to greater overall cycling efficiency.

Conclusion

Pedal frequency is a crucial factor influencing cycling efficiency and health. By maintaining an optimal pedal frequency, you can improve performance and reduce the risk of injury. Through measurement and training, every cyclist can find their ideal pedal frequency and use effective training methods to gradually improve it, ultimately achieving better cycling performance.
