Most fighters, to one degree or another, have experienced times of physical overexertion. They have overworked themselves in training by pushing their body past it’s limit. On one hand, this is an essential component to, not just elite boxers, but any athlete because “pushing yourself” is what creates progress. Stepping out of your comfort zone opens doors in and out of the ring. From a purely physical perspective we can say that whenever you perform an activity that your body is not familiar with, when you repetitively use the same muscles for extended periods at high intensity or perform any sudden, jerky motions or severe contractions you are going to feel the after-effects. This usually comes in the form of muscle soreness, fatigue and joint pain which all affect your workouts and ability to perform. Unfortunately, you can only do so much to prevent this from happening. Obviously, you have to be sure you’re warming up properly and are executing correct boxing technique or adhering to good form in all exercise/activity. This alone will help lessen the chance of injury, but when it comes right down to it, if you’re not leaving the gym feeling fatigued or sore in some way… you’re doing something wrong. However, when it reaches extreme levels, something else has to be done to aid in the recovery and enhance the recuperative ability of those muscles.
