This simple excercise is FOUR TIMES more efficient than walking

You stand at your front door, faced with a tiring three miles trek to work. But you don’t have a car and no bus roads. You can throw it out for an hour or jump on your bike and come in just 15 minutes to barely break a sweat. Select the second.

Millions of people make the same choice. It is estimated that there are more than a billion bicycles in the world. Riding a bike represents one of the most energy -saving transportation forms ever invented so far and allows people to travel faster and farther away while using less energy than walking or running. He’s reporting the conversation.

But why does pedal turning feel much easier than hitting the sidewalk? The answer lies in the elegant biomechanics of how our bodies interact with these two -wheeled wonders, London for London announces a new £ 2.2 billion tunnel under Thames with a free service bus for bicycle drivers.

A great simple machine

In your heart, a bicycle is great simple: two wheels (therefore “two cycles)), pedals that transmit from a chain to the rear wheel and the gears that allow us to fine -tune our efforts. However, this simplicity masks an engineering masterpiece that perfectly completes human physiology.

When we walk or run, we are actually moving in a controlled manner by catching ourselves at every step. Our legs should be swing on large springs and remove our heavy limbs against gravity at every step. This swinging movement alone consumes a lot of energy. Imagine: How tiring would it be to shake your arms continuously for an hour?

With a bike, your legs pass through a much smaller, circular movement. Instead of shaking your entire leg weight at any step, you rotate your thighs and calves from a compact pedal turning cycle. Energy saving is immediately noticed.

However, real productivity gains are due to how bicycles transfer manpower to action. When you walk or run, each footprint contains a mini concasion on the floor. You can hear this as the buckle of your shoe against the road and you can feel it as vibrations passing through your body. After this is sent from your muscles and joints, it is literally dispersed energy and heat.

Walking and running also includes another source of inefficiency: at each step, you brake yourself a little before pushing forward. As your foot descends in front of your body, it creates a backward force that slows you instantly. Later, your muscles should work hard to overcome this self -imposed braking and accelerate you again.

Kiss the way

Bicycles use one of the great inventions of the world to solve these problems – wheels.

Instead of a collision, you get rolling contact – kissing the road surface slightly before lifting each part of the tire. Little energy is lost to the effect. And since the wheel turns smoothly, there is no stopping acting action because the force moves perfectly to the ground. The force from your pedal turning turns into a direct movement.

However, bicycles also help our muscles work in the best way. Human muscles have a basic limitation: the faster they narrow, the weak they become and they consume more energy.

This is the famous relationship between muscles. And so it sounds much more difficult than sprint, running or walking – your muscles work close to speed limits and become less efficient at every step.

Bicycle gears solve this problem for us. You can go to a higher gear, so that your muscles do not need to work faster while the bike accelerates. Your muscles may remain at sweet points for both force production and energy cost. It is like being a personal assistant that constantly adjusts your workload to keep you in the highest performance zone.

Walking sometimes wins

But bicycles are not always superior.

More than about 15% Gradian struggles to produce enough power from the circular pedal -turning movement to lift you and the bike to the hill on the very upright hills (so you rise to 1.5 meters at every 10 meters). We can produce more power by pushing our legs directly, so walking (or climbing) becomes more effective.

Even if the roads were built, we would not pedal the Mount Everest.

This is not the case for Downhills. While riding a bike downhill becomes increasingly easier (in the end it does not require any energy), it becomes difficult to walk on the steep slopes.

When Gradian exceeds about 10% (falls one meter for every ten meters distance), each hill down, creates shocking effects that dismantle energy and emphasize your joints. Walking and running downhill is not always as easy as we expect.

Not just a transport device

The numbers speak for themselves. Cycling can be at least four times more than walking and eight times more efficient than running. This efficiency is due to minimizing three main energy drainage: limb movement, floor effect and muscle speed limitations.

Next time you go to the bike in the morning when you pass the pedestrians effortlessly, take a minute to appreciate the biomechanical art work below you. Your bike is not only a transport device, but a perfect advanced machine that works jointly with your physiology and transforms your raw muscle strength into a productive movement.
