As an expert in the field of sports physiology and exercise science, I've spent a considerable amount of time studying the intricacies of cycling and its impact on the human body. The question of the "best cadence" for cycling is a nuanced one, as it can vary greatly depending on a multitude of factors, including the cyclist's fitness level, the type of cycling being performed (e.g., road cycling, mountain biking, track cycling), and the specific goals of the cyclist (e.g., speed, endurance, recovery).

Step 1: Understanding Cadence in Cycling
Cadence, in the context of cycling, refers to the number of revolutions per minute (RPM) that a cyclist makes with their crankset. It is a critical component of cycling efficiency and performance. The optimal cadence can be influenced by several physiological and biomechanical factors.

Step 2: Physiological Considerations
When examining the physiological aspects, it's important to consider the balance between the aerobic and anaerobic energy systems. Higher cadences tend to engage the aerobic system more, which is more sustainable for longer rides. Lower cadences can lead to greater reliance on the anaerobic system, which can produce more power but is not sustainable for as long.

Step 3: Biomechanical Factors
Biomechanically, a higher cadence can reduce the force exerted on each pedal stroke, which can decrease the risk of injury and muscle fatigue. However, it requires a higher level of technical skill and cardiovascular fitness.

Step 4: Research Findings
Research has shown that there is an optimal range for cadence that minimizes energy expenditure and muscle fatigue. For instance, one study using an electromyogram (EMG) to measure the electrical activity of cycling-specific muscles found that a cadence of 80-90 RPM had significantly lower EMG activity than 70 RPM or 100 RPM, suggesting it is a more efficient pedaling rate in terms of muscle effort. However, the same study found that the lowest amount of oxygen was used when pedaling at 60-70 RPM, which is significantly less than at 80-100 RPM, indicating a more efficient use of aerobic energy.

Step 5: Practical Application
In practice, the best cadence for an individual cyclist will depend on their personal fitness, the terrain, and the duration of the ride. For long distance cycling, a lower cadence may be more comfortable and sustainable. For sprinting or climbing, a higher cadence can be beneficial for generating quick bursts of speed.

Step 6: Individualizing Cadence
It's crucial for cyclists to experiment with different cadences to find what feels most efficient and comfortable for them. This can be done through training, using heart rate monitors, and power meters to get a better understanding of how their body responds to different RPMs.

Step 7: Conclusion
In conclusion, while research provides some guidance, the best cadence is highly individual and depends on the cyclist's specific goals and conditions. It's about finding a balance that optimizes efficiency, power, and comfort for the task at hand.

Measuring the electrical activity of cycling specific muscles, called an electromyogram (EMG), they found 80-90 rpm had significantly lower EMG activity than any other cadence (70rpm, 100rpm) [3]. However, the lowest amount of oxygen was used when pedalling at 60-70rpm, significantly less than 80-100rpm [3].May 14, 2008read more >>
