“…Aerobic ability (VO2max) is the greatest aerobic exercise ability that a person has which is determined by the amount of oxygen that can enter the heart, respiration, and hemohydro-lymphatic or transport O2 and, CO2 nutrients every minute What is meant by Vo2Max is the maximum degree of aerobic metabolism in dynamic physical activity that a person can achieve (Gumantan & Fahrizqi, 2020). Higher pressure can release maximum secretions and increase oxygen saturation, but on the one hand, high pressure allows decreased oxygen saturation, trauma, hypoxemia, bronchospasm and anxiety (Suparti, 2019).
