intro

Question 1

difference between a response and an adaptation

Answer 1

responses = acute effect
adaptations = chronic effect

Question 2

difference between exercise and PA

Answer 2

exercise = planned for, voluntary activation of skeletal muscle for recreational, sporting or occupational activities
- can modulate components (intensity, duration, reps, sets, etc)

PA = any type of activity - standing, walking, not planned for

Question 3

what are the major systems involved in exercise

Answer 3

NS, skeletal muscle, CV, lungs, neuroendocrine/metabolism

Question 4

do muscle contractions disrupt homeostasis or allostasis and how

Answer 4

homoestasis
- heat dissipation during exercise = homeostatic response
- CO2 and metabolic by products are removed

Question 5

what is allostasis

Answer 5

stress specific adaptations that maintain homeostasis
- anticpatory response (happens before activity to prepare)
- occurs via production of mediators (increasing HR, BP, break down of fat and glycogen, etc

Question 6

difference between homeostasis and allostasis

Answer 6

homeostasis
- Our body fights against destructive changes
- feedback mechanism

allostasis
- our body loves constructive changes
- feed forward mechanism

Question 7

why are muscles considered service organs

Answer 7

• permit continued exercise
• blunt challenge to homeostasis
• facilitate allostasis
