Abstract
Core strengthening for stabilization and injury prevention focuses on improving muscle endurance, in contrast core training for strength and power is used to enhance the transfer of energy from the core to the extremities. The primary goal of functional training is to transfer the "improvements" in strength achieved in one movement to enhancing the performance of another movement by affecting the entire neuromuscular system.
Performing movements on unstable surfaces, typical for functional strenght training, can enhance balance, coordination, increase stability of the core, and may aid in preventing injurie. Functional strength training and Core strength training also should serve as a supplement to traditional strength training, not as a replacement.
