Oxygen is an essential element for cell growth and energy. Since your lungs are the suppliers of oxygen for your body, it is important for your overall health that they are in good shape! Processed oxygen forms carbon dioxide, which is a waste gas that is disposed of when the lungs exhale. When you’re running, oxygen requirements of key muscle groups raise, which increases your lungs’ oxygen expanse and therefore builds the lung muscles. A recent study published in the American Journal of Respiratory and Critical Care Medicine confirmed that running just 3 times a week for 30 minutes on a regular basis can immensely improve asthma control and increase lung function and aerobic capacity.
