What are some long-term effects of physical training on the blood?
a. increased production of red blood cells and greater oxygen carrying capacity
b. causes a significant decrease in plasma volume called "Runner's Anemia"
c. decrease capacity for thermoregulation and greater chance of overheating
d. decreased stroke volume and cardiac output due to greater plasma volume
Answer: a. increased production of red blood cells and greater oxygen carrying capacity
One very considerable long-term effect of physical training on the blood is an increased production of red blood cells and resultant increase in oxygen carrying capacity. The plasma volume also increases significantly and thus, actually improves thermoregulation, minimizing the chance of overheating.
