Explanation:
Detailed explanation-1: -During exercise the increased demand for oxygen is met by increasing muscle blood flow (Laughlin et al., 2012) and by improved O2 unloading from Hb achieved by decreasing Hb-O2 affinity (Mairbäurl, 1994).
Detailed explanation-2: -During exercise, your muscles are hard at work. Your breathing and heart rate increase, pulling more oxygen into the bloodstream. As you exercise, the oxygen that reaches your muscles converts available glucose into ATP, providing your body with the energy it needs to complete your workout.
Detailed explanation-3: -Exercise training can increase total Hb and red cell mass, which enhances oxygen-carrying capacity.
