Responses to Exercise Flashcards
1
Q
what is a response
A
a short term physiological function change that the body makes (e.g. heart rate, breathing rate, sweating)
2
Q
what is an adaptation
A
a long term anatomical structure change that the body makes (e.g. increased muscle size)
3
Q
what are some muscular responses to exercise
A
- increased blood supply
- increased pliability
- increased muscle temperature
- micro-tears
- lactate/lactic acid
4
Q
why is there an increase in blood supply
A
- increased demand for oxygen and glucose
- removal of waste products
- vasodilation (blood vessels widen)
5
Q
why is there an increase in body temperature
A
respiration is exothermic; produces heat in the muscle
6
Q
why is there increased pliability
A
- greater flexibility reduces risk of injury
- allows greater range of movement
7
Q
why is lactic acid produced
A
- its a by-product of anaerobic activity
- ## produced by the lactate system (high intensity activity)
