Four Times More Efficient Than Walking? Why Cycling Becomes a "Sustainable Health Habit"

When thinking "I need to exercise," many people first consider walking or running. No special equipment is needed, and you can start as soon as you step out of your house. Walking is good for your health, and running seems to build even more stamina. But what about cycling?

Cycling is often seen more as a means of transportation than exercise. Commuting, shopping, getting to the station, or taking kids to and from places—it's so integrated into our daily lives that we might overlook its benefits.

An article by Anthony Blazevich, a biomechanics expert at Edith Cowan University, introduced by the British newspaper The Independent, explains the efficiency of cycling in a very understandable way. In conclusion, cycling can be at least four times more energy-efficient than walking and about eight times more than running.

This doesn't mean "cycling is too easy to be exercise." Quite the opposite. Because it feels easy, it's easier to continue for longer periods. Because it's easier to continue, it integrates well into a health routine. The true value of cycling lies precisely in this "efficiency."

The Overwhelming Practicality of Cycling for a 5km Commute

For example, let's say your workplace is 5km from home. You can't use a car, and there's no convenient bus route.

Walking might take about an hour. Running would be quicker, but you might sweat and need a change of clothes or a shower. However, with a bicycle, you could potentially arrive in 15 to 20 minutes without having to push yourself to the limit.

This is where the wonder of cycling lies. The distance is long, yet it doesn't feel as tough. It's faster than walking and less physically taxing than running. It's not just because "it has wheels, so it's fast"; it's because the human body's mechanics align well with the structure of a bicycle.

When walking, we swing our legs forward with each step, land on the ground, support our body, and then take the next step. In running, these movements are more pronounced, and the impact upon landing increases. This means energy is used not only to move forward but also to move the legs, absorb the ground's impact, and control the body's vertical motion.

In contrast, the movement of the legs on a bicycle is closer to a circular motion. Instead of swinging the thighs and calves widely, you pedal at a steady rhythm. The body is supported by the saddle, and the feet don't slam against the ground. Much of the energy is smoothly converted into forward motion.

Walking and Running Movements Have "Small Brakes"

Walking and running are natural movements for humans. However, from an efficiency standpoint, there are unexpected losses.

At the moment the foot lands in front of the body, it touches the ground slightly ahead of the body's center of gravity. As a result, for a brief moment, a force acts like a brake on the body. We decelerate each time and then accelerate again with the next movement.

Of course, we don't usually notice this, but when walking or running long distances, we tire partly because we repeat this small deceleration and re-acceleration thousands of times.

Bicycles solve this problem with wheels. The tires roll along the ground instead of hitting it, resulting in less energy loss from impact and smoother motion. Human muscle power is converted into smooth forward movement through the mechanism of wheels.

In this sense, bicycles are not just vehicles. They are devices that amplify human physical abilities and machines that use muscle power efficiently.

Gears Keep Muscles Working "Just Right"

Another major advantage of bicycles is their gears.

Human muscles have a characteristic where they find it difficult to exert force when trying to contract quickly. The reason full-speed sprints can't be sustained for long is not only due to cardiovascular function but also because muscles themselves aren't suited to working at high speeds continuously.

Bicycle gears compensate for this weakness. Even if speed increases, switching to a heavier gear means you don't have to pedal excessively fast. On hills, using a lighter gear allows you to climb gradually without exerting a lot of force at once. This means it's easier to adjust to a range where muscles can work relatively efficiently.

This is an advantage that walking or running doesn't have. While you can change your stride or pace, it's difficult to mechanically adjust the load as you can with a bicycle. Bicycles allow for fine-tuning of exercise intensity to match the body, making them accessible for beginners, those lacking confidence in their fitness, and those training.

"Efficiency" Does Not Mean "No Exercise"

It's important not to misunderstand that just because cycling is efficient, it doesn't mean it has low health benefits.

Efficiency means less energy is needed to cover the same distance. However, by increasing the pace, riding uphill, using heavier gears, or extending ride time, cycling can become a sufficiently intense exercise.

In fact, because it puts less impact on the knees and ankles, many find it easier to continue than running. The saddle supports your weight, allowing you to strengthen your cardiovascular system while reducing joint strain. For those who want to start exercising but find running tough, or feel walking isn't enough, cycling can be a practical choice.

Organizations like the World Health Organization and the U.S. Centers for Disease Control and Prevention recommend about 150 minutes of moderate-intensity aerobic exercise per week for adult health maintenance. Cycling to work or for errands can help meet this goal in daily life.

For example, cycling to work for 15 minutes one way, five days a week, totals 150 minutes. You don't need to set aside separate time to go to the gym; the commute itself becomes exercise. This "integration of life and exercise" is a strength of cycling.

However, Cycling Isn't Always the Best Option

Of course, bicycles have their weaknesses too.

As noted in the original article, on very steep inclines, walking may be more efficient. On slopes with a gradient exceeding 15%, it's easier to exert force by firmly pushing against the ground with your feet than by pedaling in a circular motion. In situations like mountain paths or stairs, walking is more rational than cycling.

Additionally, while cycling downhill requires almost no effort, walking or running downhill means absorbing impact with each step. On particularly steep descents, the strain on the knees increases. From an efficiency standpoint, cycling is often advantageous even downhill.

However, in real-world cities, efficiency isn't the only consideration. Traffic volume, road width, the presence of bike lanes, rain or snow, parking, theft risk, and the preparation of helmets and lights all matter. Continuing to cycle involves not just physical issues but environmental ones too.

It's easy to say "cycling is good for health," but if there aren't safe roads for everyone to ride on, it won't become a habit. Efforts from individuals and urban planning perspectives are needed.

On Social Media, Voices of "I Understand" and "But Safety Is a Concern"

Looking at reactions on social media and online forums to this topic, there is not just simple praise but also quite realistic perceptions.

On Facebook, content like "cycling is an energy-efficient means of transportation" is shared through posts by The Independent and The Conversation. However, as far as can be confirmed, it seems to be quietly shared among those interested in cycling rather than causing a large buzz.

 

On Reddit, a post introducing an article on the same theme was received with comments like "combining walking, cycling, and swimming makes exercise enjoyable and less likely to lead to burnout." This is a very practical reaction. Instead of seeing cycling as the absolute, it suggests combining multiple exercises according to lifestyle and mood. As a health habit, this approach is more sustainable.

On the other hand, whenever cycling is discussed on social media, concerns about safety almost always arise. Fears of riding on the road, being cautious of pedestrians on sidewalks, the dangers of rainy days, low visibility at night, and the need for helmets and lights are common. These voices don't deny the health benefits of cycling. Rather, they highlight the social issue of needing a safe environment to use bicycles comfortably.

In summary, the reaction on social media is that "many people agree with the efficiency of cycling, but whether it can be continued depends on road conditions and safety measures."

Walking and Running Also Have Their Value

Just because cycling is efficient doesn't mean the value of walking or running decreases.

Walking is the easiest exercise to start. All you need are shoes. You can walk while enjoying the scenery, take a detour while shopping, or step outside during lunch breaks. Its light load makes it easy to incorporate regardless of age or fitness level.

Running provides strong cardiovascular stimulation in a short time. It offers a great sense of achievement and enjoyment in competition and record-setting. The feeling of speed with just your body is a different allure from cycling.

Cycling lies in between. You can go faster and farther than walking, with less impact than running. It serves as both a means of transportation and exercise. You can adjust the load to be light or heavy. That's why it's easy to incorporate into daily life.

What's important is not deciding which is the best, but choosing an exercise that fits into your life and can be continued without strain.

Tips for Making Cycling a Health Habit

If you're starting cycling, there's no need to ride long distances from the beginning. Start with a 10-minute ride to the store or station. Once you're used to it, you can extend the distance by going to a slightly farther supermarket, riding to a park on weekends, or cycling part of your commute.

For safety, lights, reflectors, helmets, and brake checks are essential. Especially at night or on rainy days, you can't assume you're visible to others. It's important to make your presence known to those around you.

When considering it as exercise, don't just coast on a gear that's too light; aim for a pace where you're slightly out of breath. A level where you can talk but not sing is a guideline for moderate-intensity exercise. Hills and headwinds can also be seen as natural resistance.

However, don't overdo it. If you experience knee or back pain, your saddle height or posture might not be right. While cycling can be a gentle exercise for the body, a poor position can cause strain. For long-term continuation, adjustments to fit your body size are essential.

From "Tool for Transportation" to "Health Infrastructure"

What makes this article interesting is that it views cycling not just as a health method but as a collaboration between the human body and machinery.

Wheels reduce impact. Pedals convert leg movement into circular motion. Gears adjust muscle function. The saddle supports body weight, enabling long-distance travel. Bicycles are designed to compensate for human weaknesses and bring out strengths.

That's why cycling tends to become "exercise that continues" rather than "exercise that requires effort." Instead of riding with determination, you're naturally moving your body while commuting. In health-building, this naturalness is a significant advantage.

The problem for modern people isn't just lack of exercise. It's not having time to exercise, not continuing once started, and avoiding overly tiring exercise. Cycling has the potential to address several of these issues simultaneously.

Of course, cycling isn't suitable for everyone. The choice depends on where you live, your fitness level, weather, road conditions, and family environment. Still, when going somewhere slightly beyond walking distance, it's worth considering "how about cycling" before using a car or train.

Walking, running, and cycling all contribute to health. However, cycling has unique attractions: "fast," "can go far," "less joint impact," and "easy to integrate into life."

Cycling is not just a means of transportation. It's a smart, accessible health infrastructure that assists the human body.
