In this assignment, you will be measuring Heart Rate at rest (while sitting), and while performing different activities (standing and walking for 5 minutes + 1 more activity of your choice).
Introduction - What is the connection between the circulatory and respiratory systems, and muscle contraction?
Prediction - What do you think will happen with Heart Rate with increasing intensity of activity?
Procedure - Pulse rate can be measured at different sites throughout the body where there is an artery located near the skin. A pulse is caused by the pumping of blood through the arteries by the heart. Heart rate can be measured through the pulse, and can be used to inform athletes as they train, and doctors who monitor their patient's health. In this experiment, various positions and exercises will be tested to determine how they affect the heart rate.
Find your pulse by placing your index and middle finger on your wrist below your thumb (where the radial artery is). Do not squeeze, but use a gentle touch. You can set a timer for 30 seconds and count the number of beats. You have to multiply the number by 2 to get BPM (Beats per minute).
Ex - For 25 beats in 30s: 25x2 = 50 BPM
In this experiment, you will measure your resting heart rate, your heart rate following activity, and the recovery of your heart rate after that activity for 10 minutes. Here are the steps:
Walk around continuously for 5 minutes, then measure your heart rate while sitting down. Record in the results section below. Continue to measure your heart rate while sitting down each minute for 10 minutes.
Complete an exercise of your choice, then measure your heart rate while sitting down. Record in the results section below. Continue to measure your heart rate while sitting down each minute for 10 minutes.
Choices may include - pushups (3 sets of 10, for example), situps (3 sets of 10-15), jumping jacks (3-5 sets of 60 seconds), jogging on spot (3-5 sets of 60 seconds), walking up and down stairs.
You may rest in between sets for 30-60 seconds. Just make sure to measure heart rate right away after the final set.
