Better Breathing Brings Peak Performance Effective breathing can make a measurable difference in Martial Arts performance and in many other endeavors we undertake. Regular deep breathing can allow the development of greater stamina, strength and mobility as well as greater mental focus, all of which are hallmarks of excellence in Martial Arts. The exhalation (breathing out) must be emphasized in order to stimulate the parasympathetic nervous system to slow the heartbeat, lower the blood pressure and lower the pulse rate. When focus is placed on the exhalation and the abs are contracted with the breath, a feeling of centeredness is developed which improves balance and coordination. Correct abdominal breathing of this kind also serves to reduce stress and clear the lungs to make room for more oxygen to be taken up on the subsequent inhalation (breathing in). Better breathing while exercising will burn more calories and encourage the development of a lean physique.
