Responses to exercise Flashcards
Response
A shot term immediate effect of exercise on the body systems during a warm up or at the start of activity
Structural response
An anatomical change to a part of the body
Functional response
The effect of the structural response on performance
Long term adaptations to the heart
> Increased max heart rate (fitter myocardium)
Bradycardia (cardiac hypertrophy - increase CO, decreased RHR)
Increased blood supply to myocardium - efficiency
Long term adaptations to the blood vessels
> Increased elasticity - reduces blood pressure
Increased capillarisation at alveoli and skeletal muscle tissue
Long term adaptations to blood
> Greater tolerance to blood lactate levels
Increased blood volume and haemoglobin count
Increased blood flow to working muscles
Long term adaptations to respiratory system
> Increased breathing rate
Increased breathing depth
Increased gaseous exchange
Primary and secondary respiratory muscles (intercostal muscles and diaphragm) - increased strength
Responses of cardiorespiratory systems to a warm up
> Increased body temperature
Increased heart rate and stroke volume
Increased cardiac output
Increased breathing rate/depth
Capillaries dilate with oxygenated blood (improved gas exchange)
Increased blood pressure in arteries
Blood shunting
Increased venous return
