Sports performance is a specialty area within bio and neurofeedback. Just ask the Italian soccer players who did neurofeedback for peak performance leading up to their 2006 World Cup victory. The critical difference was the mental preparation via neurofeedback. The players learned to visualize their winning performance while maintaining a state of focused relaxation. In other words, they sharpened their Alpha-Theta brain waves and suddenly their game was unbeatable. Biofeedback taught them how to breathe efficiently, and how to balance their muscle action to prevent fatigue and burn out. You can employ the same strategies on the golf course or during the marathon.
