Regardless of the sport or skill, it is essential to have correct biomechanical positioning, or postural control, in order to maximize energy transfer. Correct postural control requires a strong, stable core. A strong and stable core allows one to transfer energy effectively as well as reduce undue stress. An unstable or weak core, on the other hand, will not allow for optimal force or energy production and will ultimately require compensations in other areas to make up for the lack of force production. Therefore, it is important for practitioners, physical educators, and coaches to understand the injury implications associated with a weak core, the benefits of having a strong and stable core, and how to implement a core-conditioning program that will help to reduce injury and perhaps enhance performance.
