Question

1) Should your resting pulse rate be higher or lower than your post-exercise pulse rate?

2) Should your rate of respiration (breathing) before exercise be greater or lesser than the rate of respiration directly after exercising?

For #1, I think the answer should be "lower"

For #2, I think the answer should be "lesser"

Answer 1

1. Normal pulse rate of an adult is 60 - 100 beats/minute. So when a peson is exercising the heart beats faster.But post exercise resting heart rate will be low because heart muscles will be stronger and will be able to pumb more blood per beat. So the answer is "lower"

2. The normal respiration of an aduly is 12- 20 breats per minute.Whe n you start doing exercise our breathing rate increases in order to bring more oxygen in to lungs and pump more oxygen to blood and muscles. So the answer is "lesser"
