Q:What is a "Heart Rate" and how does it affect my exercise regime? Heart Rate is defined as the number of times your heart beats per minute, otherwise expressed as BPM. A change in heart rate can vary as the body's requirements for oxygen fluctuates during activities like exercise, or sleep. It is monitored by medical professionals and by individuals (such as athletes) who look t it to achieve maximum efficiency in their training.
Q: How do I find my heart rate?
One can measure their heart rate by finding the pulse of their body. The pulse can be measured at any point on the body where an artery's pulsation is felt through the surface by applying pressure with your index and middle fingers. The thumb should not be used for measuring heart rate, as its strong internal pulse may interfere with your measurements. Your pulse is lower when you are at rest and increases when you exercise (because more oxygen-rich blood is needed by the body when you exercise).
Q: But wait, whats a "Target Heart Rate" and why do I need to reach it?
By exercising in your target heart rate zone, you gain the most benefits and lessen your risks. Usually, this is when your exercise heart rate (pulse) is 60 to 80 percent of your maximum heart rate. In some cases, depending on your physical condition, your doctor or health care provider may decrease your "target heart rate zone" to begin with 50%.
How to Figure Out Your Target Heart Rate:
220 minus your age = Your maximum heart rate
Maximum heart rate x 0.5 = Low end of your target heart-rate range
Maximum heart rate x 0.75 = High end of your target heart-rate range
Heart Rate Calculator:
Mayo Clinic's Heart Rate Calculator
Understanding the Numbers:
Target heart rates are based on age. They are usually expressed as a range, such as 120 to 166 beats per minute. The lower number of a target heart rate zone, here 120, is half of the fasted BMP's that a typical person your age should have during aerobic activity. The higher number is three-quarters of the fastest heart rate that typical person your age should have during aerobic activity. If your body has adjusted and you've been exercising for a few months, you may be able to reach for the higher end of your target heart rate zone. The Maximum Heart Rate is the highest 'safe' exercising heart rate for your age.
Some Tips about Exercising in your Target Heart Rate Zone:
- Exercising about 87% of your maximum heart rate increases both cardiovascular and orthopedic risk and does not add any benefits. Keep it within a safe and healthy range, overloading your heart will just cause damage.
- To check your heart rate while exercising, stop for a minute and check your 10-second pulse. If your pulse is below your target zone, you may need to increase your rate of exercise and likewise, vice-versa.
- It's not completely necessary to exercise at your target heart rate. Moderate amounts of aerobic activity such as walking can also improve your health through lowering your risk for heart and blood vessel disease. Heart rate is just a reliable way for you to assess the intensity of your workout.
-When beginning an exercise program, you will want to spend time gradually building up to a level that is within your target heart rate zone, especially if you are just beginning a regular exercise regime.
***Remember -- No matter what your health status is, it's always a good idea to consult your doctor and ask what an appropriate target heart-rate is for you you.
