How to Use a Hand Dynamometer to Measure Pulse Rate

Exercise raises the heart rate by increasing blood flow and muscle tension throughout various parts of the body. Pulse rates are especially influenced by isometric exercises, which involves the constricting of a muscle without extending the muscle. These exercises result in elevated blood pressure and heart rate, because the heart must generate more energy to maintain the tense, fixed position isometric exercises demand. Hand dynamometers measure grip strength and are useful tools in determining a pulse rate during isometric muscle constriction. Use one or more assistants to complete measurements, if necessary.

Instructions

• 1

  Squeeze a hand dynamometer with your dominant hand. Watch the gauge needle indicate how many pounds of pressure you are exerting. Hold the force of the squeeze once you reach the desired exertion.

• 2

  Time the squeeze for one full minute.

• 3

  Release your grip and check your pulse at the one-minute mark. The pulse reading will indicate your heart rate as a result of the isometric exercise.

• 4

  Repeat steps one through three -- each with a different grip strength -- to evaluate how your pulse reacts to different levels of exertion.
