It is easy to overlook the importance of core strength for runners. It is common to focus on building strong leg and calf muscles without realizing that tremendous running gains are possible through increased core strength. The “core” is generally defined as abdominal muscles, back muscles and the muscles around the pelvis and hips. Training these muscles helps to ensure a proper, strong running form and reduce injuries.
Many studies have shown the dramatic effect that core strength can have on running. In one study, runners were split into two groups: a core strength training group and a non-core strength training group. Over the course of four weeks, the groups trained together; however, the core strength group worked on developing their abdominal and back muscles after each run.
After four weeks, the study’s authors compared the 800 meter times of the participants before the training and after the training. The core strength group improved their 800 meter times by 13 seconds on average. The non-core strength group improved their 800 meter times by 7 seconds on average.
Studies like this should give all runners the motivation to make the effort to do post-run situps and crunches. Taking time for these exercises will improve your times in the long run.
