$\underline{\huge{Answer:-}}$

Regular exercise causes an increase in the number of RBCs in the blood. As an adaptation to training, there's also an increase in plasma volume in the resting state. This volume expansion causes the hematocrit (the percentage of RBCs in blood) and hemoglobin levels to be lower than in non-athletes

Answer 2

Exercise can decrease the red blood cell mass by interavascular hemolysis mainly of senescent red blood cell, which is caused by mechanical rupture when RBC pass through capillaries in contracting muscles and by compression of red sells.
