Due to proprioceptor/sensory stimulation
Continued release of hormones
Action of muscle pump
3
Q
C) continued high HR:
A
Due to maximal workloads which continue to stress anaerobic systems
Producing lactic acid and CO2 which stimulate chemoreceptors
4
Q
D) steady rate and…
A
Some recovery of oxygen debt
5
Q
E) rapid recovery due to…
A
Cessation of proprioceptive stimuli
6
Q
F) slow recovery…
A
Clearance of metabolites (lactic acid)
Heat loss, hence muscle cooling
General body systems returning to pre-exercise levels
