Why is it important to train both Expiratory and Inspiratory muscles?
Breathing consists of moving the oxygen from the environment into the lungs, circulate it throughout the body, and removing carbon dioxide out. This process is called gas exchange. Inspiration results from enlarging the thoracic cavity and lowering the intrathoracic pressure to intake air. Exhalation occurs when relaxing the inspiratory muscles and the chest springs back forcing the air out of your lungs. During normal daily activities, you breathe at ease and the respiratory muscles do not experience hard work, hence blood flow to the peripheral muscles is normal. To give you a better idea, at rest a person breathes around 12 liters of air per minute, but during heavy exercise this can rise to over 150 liters per minute, and in elite athletes, this can go as high as 220 liters. When performing an exercise or an intense activity, the work of breathing increases making the respiratory muscles work harder. This causes fatigue and can reduce the blood flow, which limits physical performan
