Initial responses of the cardiovascular and respiratory systems to exercise?
Wiki User
∙ 13y ago
Cardiovascular changes:
· Heart rate increases partly due to demand of the exercise plus partly due to the anticipation of exercise (cause: adrenaline associated with the anticipation of physical exercise think of standing at the blocks before a 100m race)
Respiratory response
· Increased breathing rate
· Increase in tidal volume
· Pulmonary ventilation therefore increases
· Intercostal muscles
· Valsalva manoeuvre
Its pretty darn easy to so try a little bit harder!

Why is there an initial rapid increase in respiration rate during exercise?
Your body requires more oxygen when it's performing exercise, and as a result, you will take more breaths per minute to satisfy the increased oxygen demands. Oxygen is needed to efficiently convert glucose to ATP (your body's cellular energy source), and exercise certainly requires added energy.
