Heart Rate Recovery and Your Cardiovascular Health

There are a lot of numbers about ourselves that most people are aware of; cholesterol levels, blood pressure and resting heart rate. But there's a very important number many people have never heard of.

When you move quickly or do something that takes effort, how long does it take for you to recover? Does your heart rate return to normal quickly, or are you left panting and out of breath for several minutes?

When you exercise, your heart rate increases to meet the increased demand for oxygen and nutrients by the body's working muscles. After the exercise session, the heart rate gradually returns to its resting rate. The speed at which this occurs is known as heart rate recovery (HRR).

It's an important indicator of cardiovascular health, as it can provide insights into the efficiency of the cardiovascular system. A slow heart rate recovery can be an indication of underlying health problems. A study published in the New England Journal of Medicine found that a slower heart rate recovery was associated with a higher risk of death from all causes, including heart disease.

Several factors can affect heart rate recovery, including age, fitness level, and exercise intensity. Older individuals generally have a slower heart rate recovery than younger people. Additionally, those who are less fit tend to have slower heart rate recovery times than those who are physically active.

If you want to test yourself, three things can affect the results.

Avoid caffeine at least 12 hours before a test. Since caffeine stimulates the nervous system, it can take longer for you to recover.

Drink plenty of water. If you're dehydrated, your heart rate can increase more than normal. A lack of water can also slow down how quickly your heart rate recovers.

Get plenty of rest before the day you test. Fatigue can alter both your peak heart rate and the speed of your recovery.

Calculating heart rate recovery is a straightforward process. Start by using a good heart rate monitor. You'll need two numbers.

  1. Your peak heart rate during exercise. When you finish the most intense part of your workout, write down your heart rate.

  2. Rest for one minute, then recheck your heart rate.

Now some simple subtraction. The answer is heart rate recovery in beats per minute. Take your peak heart rate and subtract your heart rate after one minute. This is HRR Fast Phase.
