Physical Exertion While Cycling Outperforms Walking by a Fourfold Margin, According to a Biomechanics Specialist's Insights
In today's fast-paced world, commuting to work can often be a challenge. However, for many, the solution lies in the humble bicycle. This simple yet ingenious invention offers a range of benefits that make it an attractive choice for daily transportation.
One of the key advantages of cycling is its energy efficiency. Compared to walking, a bicycle can cover the same five-kilometre commute in just 15 minutes, a significant time-saving advantage. But it's not just about speed; the energy efficiency of cycling is also unparalleled. It's estimated that cycling is at least four times more energy-efficient than walking and eight times more efficient than running. This is due to the bicycle's ability to reduce energy loss from impact and eliminate stop-start braking action, as well as its biomechanics that save energy compared to walking or running.
The biomechanics of cycling are a key factor in its energy efficiency. Unlike walking or running, where feet collide with the ground, causing energy loss, bicycles use rolling contact instead of collision, reducing energy loss. Moreover, the biomechanics of cycling allow for a smaller, circular motion of legs compared to walking or running, transferring human power to forward motion more efficiently.
The low-impact nature of cycling is another significant advantage. As a low-impact activity, cycling significantly reduces stress on weight-bearing joints like knees and hips compared to running or walking. This lowers the risk of overuse injuries and joint soreness. The biomechanics of cycling also allow for better control of joint angles through equipment setup, such as adjusting crank length, which reduces excessive hip and knee flexion at the top of the pedal stroke, enhancing comfort, and preventing injury.
Cycling also promotes higher cadence and cardiovascular efficiency. Shorter cranks and bike positioning promote a higher pedal cadence that shifts stress from muscular to cardiovascular systems, helping conserve leg muscle fatigue while boosting cardiovascular capacity. This is different from the muscular strength focus of running.
The biomechanics of cycling make it a biomechanical work of art that works in partnership with the physiology, turning raw muscle power into efficient motion. This is a testament to the meticulous study of biomechanics experts like Professor Anthony Blazevich, Professor of Biomechanics at Edith Cowan University.
However, it's important to note that on very steep hills (over 15% gradient), walking or climbing becomes more effective than cycling due to the struggle of legs to generate enough force. Nevertheless, the benefits of cycling far outweigh this minor drawback, making it an attractive choice for many commuters.
In conclusion, the biomechanical advantages of cycling stem from its smooth, low-impact mechanism, ability to finely tune joint angles and posture, improved muscular and cardiovascular efficiency, and enhanced injury prevention compared to the repetitive impact and joint stress in walking or running. This makes cycling one of the most energy-efficient forms of transport ever invented.
