Someone please point me in the right direction with attempting this task, any help is much appreciated
Write a discussion summarizing and explaining changes in energy physiology and metabolism of the body to deal with the needs of the body at rest, during and after exercise.

Hi, to push you off the cliff [NOT literally! ] look up ALL the following and expand on them:-
AT REST:
1. Heart rate and breathing rate controlled by parasympathetic tone and
modulating influence of cardiac centre and respiratory centre in medulla oblongata
2. Oxygen dissociation curve (sigmoid in shape) ensures base-level saturation with O2 in lungs and release of O2 in tissues.
3. Glycogenesis prevails together with fat deposition - anabolism greater
EXERCISE:
1. increased sympathetic activity -----> Release of adrenaline (alpha + beta effects) and noradrenaline (mainly alpha) ------->
+ve chronotropic effect -----> tahycardia
+ve inotropic effect -------> increased stroke volume
2. Muscle arterioles dilate by action of beta2 adrenoceptors
3. Tachypnoea + deeper ventilation ----- > greater O2 transfer
4. O2 dissociatiion curve shifts to right (Bohr shift) due to rise in CO2 levels -----> more O2 released in tissues
5. More catabolic activity - glycogenolysis prevails
