Heart Rate Calculator

The heart rate is measured by applying gentle pressure to any part of the body where the artery is close to the skin and pulsations can be felt. The radial region of the wrist is the most convenient area (radial heart rate). Other places to look for heart rates include the side of the neck (carotid heart rate), the groyne (femoral heart rate), and the side of the feet (plantar heart rate) (Posterior tibial artery heart rate).

You are sweating if your heart rate is too high. Take it easy! If your heart rate is too low and the intensity feels "light" to "moderate," you should push yourself to exercise more vigorously, especially if you're attempting to lose weight. A maximal exercise test (value can be entered into the calculator directly) or an age-predicted formula can be used to calculate HRmax.

There are two formulas that are currently in use:

HRmax = (220 – age) (which is reported to be simpler to use).

The Karvonen formula, which calculates results as a function of heart rate reserve (HRR) and maximum heart rate, is frequently used for this purpose (HRmax).

HRR = HRmax - HR rest

Where,

HRR be the heart rate reserve

HRrest is the resting HR of the individual

HR range is calculated as follows:

HRR= (HRR x desired training intensity) + HRest

HRmax (THRmax) is calculated as follows:

HRmax= (desired training intensity) x (HRmax)

Maximum and Target Heart Rates as a Function of Age
The desired heart rate zones for various ages are shown in this table. 220 minus your age is your maximal heart rate.

Age	Target HR Zone 50-85%	Average Maximum Heart Rate, 100%
20 years	100-170 beats per minute (bpm)	200 bpm
30 years	95-162 bpm	190 bpm
35 years	93-157 bpm	185 bpm
40 years	90-153 bpm	180 bpm
45 years	88-149 bpm	175 bpm
50 years	85-145 bpm	170 bpm
55 years	83-140 bpm	165 bpm
60 years	80-136 bpm	160 bpm
65 years	78-132 bpm	155 bpm
70 years	75-128 bpm	150 bpm

Methods to count the pulse rate at the wrist

• Turn the hand so that the palm is facing up.
• Just below the thumb, place your index and middle fingers.
• Apply mild pressure to the wrist bone with your index and second fingers.
• Using a watch or clock to count the pulse for 30 seconds and multiply the result by two.

Heart Rate Calculation Examples

1. To calculate the heart rate reserve for a 40-year-old with a resting HR of 71bpm with the training intensity is 41-58%.

Solution:

Given that,

Age is 40 years

HRrest is 71bpm

The training intensity is 41-58%

Formula used to calculate the problem:

HRR = HRmax - HR rest and HRmax = (220 – age)

Heart Rate Reserve(HRR) = [(220 – 40) – 71] 

Heart Rate Reserve(HRR) = [180 – 71]

HRR = 109bpm

HRR= (HRR x desired training intensity) + HRest

HHR = 109 * 0.41 + 71

HHR = 109 * 0.41 + 71 and  109 * 0.58 + 71 

HHR = 44.69 + 71= 115.7 bpm and  63.22 + 71 = 134.22 bpm

HRR = HRmax - HR rest

HHR = 116 – 134bpm

1. Mention the formula to calculate heart rate reserve.

The Karvonen formula, which calculates results as a function of heart rate reserve (HRR) and maximum heart rate, is frequently used for this purpose (HRmax).

HRR = HRmax - HR rest

Where, HRR is the heart rate reserve

2. How can you figure out your heart rate?

Place two fingers between the bone and the nerve above your radial artery, which is on the thumb side of your wrist, to check your pulse. Count the number of beats in 15 seconds when you feel your pulse. Calculate your beats per minute by multiplying this amount by four.

3. What is the best way to count the pulse rate at the wrist?

1. Turn the hand so that the palm is facing up.
2. Just below the thumb, place your index and middle fingers.
3. Apply mild pressure to the wrist bone with your index and second fingers.
4. Using a watch or clock, count the pulse for 30 seconds and multiply the result by two.
