As one improves in the competitive arena through multiple repetitions, repetitive injuries begin to creep in. Balanced training, or crosstraining, may assist the health of the athlete, but may also overtrain the athlete. In addition, the effort spent to balance training takes away time and energy from training the sport. One might be healthier, but in second place. It is important to define health.
Health is the systems of the body working optimally.
Fitness, on the other hand, is the ability to perform a task. Using the Harvard step test to test the health of wheelchair bound individuals would be obviously wrong, yet we often use running to test the health of strength and power athletes, like football players. Drink water, don t smoke, wear a seat belt, avoid sugar, and keep your relationships healthy. Simple advice, but often ignored during the season. If your not using your seat belt, ignore discussions about creatine.
