While the question ‘do we need strength training in running?’ is not a question anymore, the question, ‘what kind of strength do we need there?’ is still unclear. That is why I would like to discuss this topic in a short description of the logic of strength exercise use in running. It is no secret that muscle strength is necessary in running to provide for the body’s ability to interact with the ground while your body moves from one support to the other. During support time gravity manifests itself as the body weight and muscles provide for its ability to interact with the ground. So…

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…

Stride frequency describes how often a runner changes support during running. Around 180 steps per minute the muscle–tendon system begins to contribute elastic energy, reducing muscular effort and improving efficiency. Here is the research behind this number and what it means for running technique.
