By Greg Wells PhD and Jessica Caterini BSc
The "core" is a common term used to refer to the middle section of the body between the lower part of the rib cage and the hips. There are 29 muscles in this area including the pelvis, spine, lower back, hips and trunk. Core muscles maintain body stability and transfer power from the legs to the upper body and vice-versa. Core strength training improves overall body functional power, balance, posture and may help reduce the risk of injury. By understanding and applying the science related to the core muscle stability and strength, you can develop more effective running mechanics and avoid lower back pain and other physical challenges.
