Document Summary

Difference with blood pressure response b/w arm and leg workout. As intensity increases, both diastolic and systolic pressures are higher in arm work vs leg. This is related to the radius of the vasculature, the diameter of the vessels in the upper limbs compared to the lower limbs. Smaller muscles have smaller vasculature- reduction in radius and see increase in blood pressure- with smaller diameter of vessels, need greater pressures to maintain the same blood flow as leg. People who have heart problems (coronary heart disease) have reduction in diameter of vessels. Have intermittent isometric contraction when shovelling and have more heart problems when doing this. People who are hypertensive also have to be careful when doing sports with arms (e. g. rowing) review: visocity: Becoming dehydrated and loosing water from blood volume (from plasma) meaning concentration of hb relative to whole blood will increase.
