Downhill running, DOMS, and eccentric training

Downhill running, DOMS, and eccentric training

Here we’ll discuss the significance of eccentric contractions during downhill running and its contribution to DOMS (delayed onset muscle soreness). We will also look at the effectiveness of eccentric training as part of a strength or rehabilitation training program. Most of you will be familiar with the paradoxical muscle soreness resulted from running downhill felt a few days following a training session. During a descent, the body’s running biomechanics significantly changes to facilitate a new landing pattern which acts to counteract downhill acceleration. In doing so, the quadriceps muscles in particular undergo a greater degree of eccentric muscle contraction which aids in neutralising the accelerative force component. (adsbygoogle = window.adsbygoogle || []).push({}); What is an eccentric contraction? Although ‘contraction’ would suggest something shortening, in muscle physiology it describes the production of tension. Tension in a muscle can be produced under 3 scenarios: Muscle shortening = concentric muscle contraction Muscle lengthening = eccentric muscle contraction Muscle remaining same length =...
