A new analysis has revealed that cycling is up to four times more efficient than walking for improving aerobic fitness. The findings, published in a health forum, suggest that while both activities offer health benefits, cycling allows individuals to reach the necessary training threshold with less technical difficulty.
To achieve an aerobic training effect—improving oxygen uptake and utilisation in the muscles—individuals need to work at 70 to 90% of their maximal aerobic capacity. For a five-mile distance, this would require cycling fast or walking at an unusually high pace. Experts note that walking at such a speed is difficult without practice, whereas cycling makes it easier to reach the threshold.
However, the benefits are activity-specific. Aerobic power improvement primarily affects the quadriceps in cycling and the plantar flexors in walking. Therefore, cycling training does not enhance walking performance, and vice versa. Neither exercise confers fitness advantages for other activities.
For general heart health, both activities at easy intensity can reduce bad cholesterol, increase good cholesterol, and lower blood pressure without needing to reach training thresholds. Walking five miles may expend more energy than cycling five miles on flat terrain, offering greater weight control benefits. Additionally, walking carries lower risks of road traffic accidents, making it potentially better for those seeking health improvements without increased fitness.
