Activity 2: Pulse Lab

Directions for prepping to do the lab:
1.Decide where you are going to find your pulse. Remember, the best places to find your pulse are on your neck and your wrist. Pick wherever is easiest to feel your pulse.
Measuring your Resting Heart Rate
2. Make sure you are in a comfortable position, find your pulse, and count how many times your heart beats in 15 seconds. Set a timer on your watch or phone.
3. Now it’s time for a little math. Remember that your heart rate is how many times your heart beats in 1 minute, or 60 seconds. You counted for 15 seconds so you’ll need to multiply the number you came up with by 4. For example, let’s say you counted 25 beats in 15 seconds:
25 beats x 4 = 100 beat per minute (bpm)
Your resting heart rate would be 100 bpm.

Now we are ready to begin the lab.
