Find out what happens to your heart when you do physical activities!

Heart rates are calculated beats per minute (bpm). Your regular resting heart rate (when you are not doing any physical activities) should range between 60 to 100 bpm.
a) What happens to your heart rate when you exercise?
b) Do you think different types of exercise will affect your heart rate differently?
c) Use this table to calculate your heart rate. (Pulse)

a) When you exercise, your heart rate increases to provide your muscles with the oxygen and nutrients they need to function properly. The increase in heart rate is a normal response to physical activity, as the body tries to meet the increased demand for energy.

b) Yes, different types of exercise can affect your heart rate differently. For example, aerobic exercises like running or cycling can cause a greater increase in heart rate than resistance exercises like weightlifting. This is because aerobic exercises require more oxygen to be delivered to the muscles, which requires a higher heart rate to pump more blood.

c) To calculate your heart rate using the table, you need to count the number of beats in 10 seconds for each activity and then multiply that number by 6 to get the beats per minute. For example, if you count 15 beats in 10 seconds while walking, your heart rate would be 90 bpm (15 x 6). If you count 20 beats in 10 seconds while jumping, your heart rate would be 120 bpm (20 x 6).

Answer:

a) What happens to your heart rate when you exercise?

Well, when you exercise, your muscles breakdown glucose to release energy to carry out the exercise. The heart rate increases, pumping more blood to those muscles to supply them with enough glucose and oxygen.

b) Do you think different types of exercise will affect your heart rate differently?

Yes it will because, different exercises require different energy levels from the muscles. The heart rate of a girl walking won't be the same as when she is running.
