Core stability is contributed by muscle strength/endurance and neuromuscular control of the trunk. Maintaining or resuming an equilibrium position of the trunk after perturbation is essential for exercise. Many athletes carry out core muscle training to increase core stability for enhancing performance and reducing lower limb injuries. Once core stability can be effectively and appropriately estimated, the performance and the risk of injury in athletes can be predicted indirectly. However, there are many ways to evaluate core stability and they can be categorized into two types: strength/endurance of muscle and neuromuscular control of the trunk. In this article, different evaluation methods were evaluated. Strength and weakness of the training modes were also discussed.
