Effects of exercise
RED= Short term effects Blue= Long term effects
CV system:-
More nerve impulses to heart pacemaker increasing h/r
Adrenaline secretion = increased H/R
Nitric oxide secretion is stimulated by a drop in oxygen levels
dilating arteriole, which increases flow back to heart and
increases cardiac output
Diversion of blood flow to muscles
Increased no. of red blood cells
Hypertension of cardiac muscles
Lower H/R
Breathing rate increases
Tidal volume increases
Increased max breathing rate
Increased vital capacity
Increased muscles size
Increased no. of slow twitch fibres
