## All about heart rate

Whether after a good gym session, an exciting event, or a jump scare while watching a good horror movie, we often become aware of our heartbeat — especially when it becomes faster than usual. Our heart rate is one of the essential measurements in determining our overall health, but what exactly is it?

**The heart rate is a measurement of how many times your heart beats (contracts) per minute (bpm).** Experts believe that healthy adults' normal **resting heart rate is 60 to 100 beats per minute.**

- A lower
*resting*heart rate is associated with reduced odds of heart attacks. - A higher
*resting*heart rate could indicate lower physical fitness and higher blood pressure. - A
*resting*heart rate lower than 60 or higher than 100 bpm counts as an**irregular heartbeat**, and should be addressed by a medical professional. 👩⚕️

## Calories burned based on heart rate

By now, you're probably wondering **how heart rate is related to calories burned** and where exercise comes into play. When exercising (or doing any intense physical activity), your heart beats faster to supply extra oxygen to your muscles under tension. Since we **expend approximately five calories for every liter of oxygen consumed,** the increased oxygen consumption leads to more burned calories. Therefore, although a higher **resting heart** rate isn't optimal, **increasing heart rate during exercising may lead to more excellent fitness.** If you're wondering what should be your target heart rate during various types of exercises, don't forget to check out our target heart rate calculator

🙋 If you're interested in indicators of your cardiorespiratory fitness, you can determine your maximum rate of oxygen consumption (your VO_{2} max) during an intense exercise at your local sports medicine facilities.

## How do you calculate calories burned based on heart rate?

Formulas that you can utilize to calculate calories burned according to heart rate differ depending on the gender and whether VO_{2} max is known or not.

**If VO _{2} max is unknown,** the following formulas would apply:

**Women:**

`CB = T * (0.4472*H - 0.1263*W + 0.074*A - 20.4022) / 4.184`

**Men:**

`CB = T * (0.6309*H + 0.1988*W + 0.2017*A - 55.0969) / 4.184`

Where:

`CB`

is the**number of calories burned**;`T`

is the**duration of exercise**in minutes;`H`

is**your average heart rate**in beats per minute;`W`

is**your****weight**in kilograms; and`A`

is**your age**in years.

**If your VO _{2} max is known,** the following formulas would apply:

**Women:**

`CB = T * (0.45*H + 0.380*V + 0.103*W + 0.274*A - 59.3954) / 4.184`

**Men:**

`CB = T * (0.634*H + 0.404*V + 0.394*W + 0.271*A - 95.7735) / 4.184`

Where:

`CB`

is the**number of calories burned**;`T`

is the**duration of exercise**in minutes;`H`

is your**average heart rate**in beats per minute;`V`

is your**maximum rate of oxygen consumption**, VO_{2}max, in ml/kg/min;`W`

is**your weight**in kilograms; and`A`

is**your age**in years.

## FAQ

### How do I calculate VO2 max?

To measure your VO_{2} max, use the following formula:

`VO₂max = 15.3 * (MHR / RHR)`

where:

`MHR`

is your maximum heart rate (equal to`220 − your age`

); and`RHR`

is your resting heart rate.

For example, if you're 20 years old, you have a `MHR`

of `200`

. If your `RHR`

is `80`

, your VO_{2} max would be approximately `15.3 × (200/80) ≈ 38.25`

. You can get a more accurate measure of VO_{2} max at your local sports medicine facilities.

### How do I calculate my heart rate?

To check your heart rate, **gently press the pointer and middle finger on your opposite wrist, below the thumb,** where you feel your pulse. Then you should **count the number of beats** for 15 seconds and multiply that number by four to determine your heart rate.

### Does high heart rate during a workout burn more calories?

In general, the **higher your heart rate is** during exercising, **the more calories you burn per minute.** You can also calculate calories burned according to your heart rate, where during a high-intensity exercise, there is a correlation between heart rate and calories burned.

### What is a normal resting heartrate?

Healthy adults' normal **resting heart rate is 60 to100 beats per minute.**
