MAKE ME BEATMAKE ME BEATHeart rate after exercise

What is the changes of your breath after you playing badminton?

Start this experiment when you are at normal condition.

Clip the pulse sensor on your finger.

Connect the pulse sensor to data logger.

Start the data logger to obtain the graph about 3 minute.

Running for a few minutes as warming up.

Data logger was started while you are running and obtain a 3 minutes graph.

Observed the changes of graph.

What do you observe after you run? How will your heart rate change? What is the pattern of your graph? What are the relation between your heart rate

with the exercise you have done? What affects your heart rate when you are in

relax state?

My breathing become faster. Increase after exercise. Always at the high level but constant. Heart rate will increase when exercise is carry

out. Talking, thinking, laughing, moving, etc…

• Adventured activities such as bungee jumping and kayak increase our heart rate.

Doctor will use stethoscope to listen to our heart beat. What do you think about our heart rate when we are sick?
