increase in LVEDV
during exercise LVEDV increases....as contracting mus. pumps more blood to heart...left ventricle fills more completely, stretching it further, with the elastic recoil producing a more forceful contraction increasing SV..n decrease in LVESV.....Frank-Starling mechanism.....
in short der is increase in LVEDV N SV...
but a decrease in LVESV as heart is emptying more completely....
