short term effects of exercise 1.4.1-1.4.4

Question 1

What are the short term effects of exercise on muscles

Answer 1

Lactic acid, oxygen debt, Muscle fatigue, muscle temp increase

Question 2

What is oxygen debt

Answer 2

the shortage of oxygen in the muscles which forms lactic acid

Question 3

What are the short term effects of exercise on cardio vascular system

Answer 3

Stroke volume increases, heart rate increases, cardiac output increases

Question 4

What is stroke volume

Answer 4

the amount of blood pumped from heart per beat

Question 5

what is cardiac output

Answer 5

the volume of blood pumped from the heart per min

Question 6

how do you calculate cardiac output

Answer 6

stroke volume * heart rate

Question 7

What are the short term effects of exercise on respiratory system?

Answer 7

Increase in tidal volume

Question 8

how does the cardiovascular system and respiratory system work together to allow physical activity

Answer 8

they help get oxygen to working muscles and remove CO2 from body
during exercise muscles need more oxygen in order to contract and they produce more CO2 waste
So tidal volume increases and heart rate increases to meet demands
