Answer 22

60 seconds

Question 23

Factors that may affect resting heart rate

Answer 23

Digestion
Mental activity 
Environmental temperature 
Biological rhythms 
Body position 
Cardio fitness

Question 24

When measuring a pulse during exercise how long do you count?

Answer 24

6 seconds

Question 25

When measuring a pulse for only 6 seconds during exercise how do you calculate the HR?

Answer 25

Add a zero,, if you counted 12 beats adding a zero you give you 120 bps, or multiple by 10 which will also give you 120
