Detailed explanation-1: -When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute (12 litres of air) when you are resting, up to about 40–60 times a minute (100 litres of air) during exercise.
Detailed explanation-2: -Findings discovered, obtaining a seated slumped posture significantly decreased lung capacity and expiratory flow. Sitting upright improved this along with a standing posture, allowing higher levels of lung capacity and healthier expiratory flow.
Detailed explanation-3: -During breathing at rest, this is accomplished by the coordinated activity of the diaphragm and inspiratory rib cage muscles.
