Soc 19: Short Term Effects of Exercise

Question 1

What are the short term effects on muscles?

Answer 1

Muscles fatigue as a result of anaerobic respiration and can cause cramps.
Lactic accumulation.

Question 2

What are the short term effects on the heart?

Answer 2

Heart rate increases (athletes tend to have lower resting heart rate and quicker recovery rate).
Stroke volume increases as a result of heart increasing in size, strength and thickness.
Cardiac output increases.

Question 3

What is cardiac output?

Answer 3

The amount of blood ejected from your heart per minute.
Stroke Volume x Heart Rate

Question 4

What is stroke volume?

Answer 4

The amount if blood pumped by the heart during each beat.
If it increases, heart rate will decrease.

Question 5

What is lactate accumulation?

Answer 5

When lactic acid gather in the muscles/blood due to increased work intensity.

Question 6
