Q How quickly could a human theoretically sprint?
A Bryan Heiderscheit, professor in the department of orthopedics and rehabilitation at the University of Wisconsin-Madison:
The current world record for running rate is kept by Jamaican Olympic champion Usain Bolt at about 28 miles per hour, and it’s hard to imagine running quicker.
However, some individuals have theorized that it could be possible for humans to operate as fast as 40 miles per hour under ideal circumstances and circumstances. This rate is a theoretical limitation as to what might be potential — diverging from many tests and the force-producing capabilities of people’ lower legs — but it has never been detected.
When speaking about attaining a rate of 40 miles per hour, it’s only in terms of running on level ground. We’re not talking about running mountains or down hills, or under circumstances on a treadmill which might be more challenging to perform. The perfect circumstances require no wind or air resistance, no concerns about fatigue-related issues along with the other physiological factors that might play a role.
As a result, the odds of reaching 40 miles per hour is very slim.
Several factors are associated with how fast somebody can operate, which is why only one person has ever run 28 miles per hour. The period of your lower leg bones relative to your general leg, the period of your foot bones or the place where your leg and its tendon attach to a ankle joint may play a role in running speed.
And these variables can’t be changed by you. You can’t train your bones to be more. You can’t instruct your muscle to attach closer to a joint.
However, you may change how your muscles work and how much power they create to improve your running speed.
