An Ohio State University study found evidence that suggests that runners who lack deep core muscle strength are more susceptible to low back pain. The supposition is that if those deep core muscles aren’t being activated enough then the superficial core muscles such as the abdominals will help to compensate. When the superficial muscles are forced to pick up the slack during running they are more likely to tire out prematurely. Overall, when the deep core is weak the rest of the body will compensate, this puts more pressure on the spine and the likelihood of developing chronic low pain increases. Researchers suggest using static core exercises to activate and strengthen the deep core muscles.
