Document Summary
We talked about indirect support for the benefits of exercise, but when we look at the whys of this support, what does the direct evidence reveal: active animals have larger, heavier, healthier hearts. Larger does(cid:374)"t (cid:374)e(cid:272)essarily (cid:373)ea(cid:374) healthier (cid:271)e(cid:272)ause of fat, (cid:271)ut heavier a(cid:374)d larger means muscle. Increased left ventricle: active animals larger coronary arteries, active animals less plaque buildup in arteries, all of these same things hold true in humans. Improves blood lipid profile (increases hdl good cholesterol; decreases ldl (bad cholesterol; and decreases total) What other heart healthy benefits are provided by exercise: thinner blood, more plasma, hematocrit is reduced, ability to dissolve clots goes up and to form clots is less. Improved blood lipid profile (more hdl (good) and less ldl (bad)) Decreases total cholesterol: body fatness and heart workload go down, exercise lowers heart rate, blood pressure and work of heart, good stress outlet.
