It's a fun way to learn about your heart rate and how it changes during exercise. Results will be mixed.  Some people will have to hunt around for a good spot on their wrist.  Once you find it you might want to mark it to remember where it is. Good way to figure out your heart beats is to time for 15 seconds while you counted the heart beats.  Then multiplied by four to approximate our heart rate per minute. Average heart beats are 60-100 beats per minute for kids ages 10 to adults. Kids under 10 usually have a faster heart rate then adults. Now try to to do some jumping jacks for a couple minutes and then try this experiment again to see if you heart beats go up or down. What is the pulse rate? The pulse rate is a measurement of the heart rate, or the number of times the heart beats per minute. As the heart pushes blood through the arteries, the arteries expand and contract with the flow of the blood. Taking a pulse not only measures the heart rate, but also can indicate the following: - Heart rhythm - Strength of the pulse The normal pulse for healthy adults ranges from 60 to 100 beats per minute. The pulse rate may fluctuate and increase with exercise, illness, injury, and emotions. Females ages 12 and older, in general, tend to have faster heart rates than do males. Athletes, such as runners, who do a lot of cardiovascular conditioning, may have heart rates near 40 beats per minute and experience no problems. How to check your pulse As the heart forces blood through the arteries, you feel the beats by firmly pressing on the arteries, which are located close to the surface of the skin at certain points of the body. The pulse can be found on the side of the neck, on the inside of the elbow, or at the wrist. For most people, it is easiest to take the pulse at the wrist. If you use the lower neck, be sure not to press too hard, and never press on the pulses on both sides of the lower neck at the same time to prevent blocking blood flow to the brain. When taking your pulse: Using the first and second fingertips, press firmly but gently on the arteries until you feel a pulse. Let me know your results in the comments below.
