Determining Your Training Heart Rate
It is important to accurately determine your individual training heart rate before you begin any exercise program. This number is a critical component in understanding the intensity in which your heart is working while you exercise. It begins by calculating your maximum heart rate (MHR). The formula is 220 minus your age.
For example, if you were 35, your maximum heart rate would be 220-35= 185 beats per minute.
The next step is to determine your heart rate reserve by utilizing the Karvonen Formula. Begin by taking your resting heart rate in the morning before rising from bed. Take your pulse for one minute with the first beat starting with 0.
Now you must determine the intensity in which you should be working out to maximize your exercise and reach your goals. For most people the range is 50%-85% of your heart rate reserve.
Beginner or low fitness level= 50%-60%
Average fitness level= 65%-75%
High fitness level= 75%-85%
With all of these components in place you are now ready to determine your training heart rate using the formula.
MHR-resting heart rate X intensity +resting heart rate= Training Rate
For Example:
Beth is 35 years old and has a resting heart rate of 72. Her intensity level is 65%-75% of her maximum heart rate.
220-35= 185 (MHR) 185- 72 X .65 + 72=145 185-72 X .75 + 72= 156
With this new knowledge, Beth should be training within the range of 145-156 beats per minute.
Training rates are only guides and should be accompanied by perceived exertion rates to accurately measure how hard you are working. Consult a professional personal trainer for more information on how to utilize your training heart rate for your own workout program.
