Breathing Muscles

Of all the vital muscles necessary for optimal endurance, perhaps the most important one is the diaphragm. This breathing muscle is located on top of our abdomen and under our lungs. The large, flat muscle allows us to breathe by pulling in oxygenated air and expelling unwanted carbon dioxide. In well-trained endurance athletes, the breathing mechanism may be the weak link in good performance. In this case, less air enters the lungs and the blood does not receive the proper amount of oxygen. Moreover, poor exhalation does not eliminate the necessary amount of carbon dioxide, which can also reduce endurance.

All athletes can incorporate the actions of normal breathing into their training program—not necessarily during training, but most especially during rest or down time. This can help recovery and actually help repair muscle and other imbalances.
