Many runners try to control how high their foot travels without realizing what actually determines it. This article explains why foot height is a…

One second in one hundred years raises a difficult question. In a century of technological and scientific progress, sprinting has barely improved.

Runners struggle to improve speed because the traditional speed formula is incomplete. Without accounting for this key element, cadence and stride length cannot explain or produce speed.

Andre De Grasse’s plateau exposes a recurring flaw in sprint training: isolated physical qualities rise, yet speed remains unchanged. His case highlights the deeper mechanism most approaches overlook.

At just 17, Gout Gout runs with stride lengths rivaling Usain Bolt. Yet he lacks the power base of elite sprinters. This paradox raises new questions about what really drives performance in sprinting.

Runners often confuse stride length with range of motion. One measures movement; the other enables it. Knowing the difference changes how you run.

Usain Bolt could run 100m in 9.11 seconds. Given his constitution, genetics and his running technique he has what it takes and then some.

Whatever your current running speed is, you can run faster immediately by simply changing just one thing. Nothing else will give you the same result.

In general, better balance translates to higher precision of movement regardless of sport, but how does our balance affect our speed?

What is muscle elasticity? If you were to stretch a muscle you would see it shrink back a bit. In plain words, it’s a natural ability to recover to original form upon the removal of the force initially applied. In physical activity it is the ability of muscles to perform work, specifically, to contract rapidly after and immediately prior to extension. A human body is a mix of physics, geometry, psychology and all that good stuff, so we should not talk about muscles and their function as separate from the whole. Muscles are a part of our entire system, and…
