The calories burned by heart rate calculator helps individuals track their energy expenditure during physical activities by monitoring their heart rate.
A 30-year-old woman weighing 65kg, who maintains an average heart rate of 140 BPM during a 45-minute cycling session. The calculator use these parameters to estimate her caloric burn, considering both her aerobic effort and basal metabolic rate.
Calories Burned by Heart Rate Calculator
| Age | Weight (kg) | Gender | Heart Rate (BPM) | Duration (min) | Calories Burned |
|---|---|---|---|---|---|
| 25 | 70 | Male | 140 | 30 | 325 |
| 35 | 65 | Female | 150 | 45 | 412 |
| 45 | 80 | Male | 130 | 60 | 589 |
| 30 | 58 | Female | 145 | 40 | 334 |
Calories Burned by Heart Rate Calculation Formula
The formula used for calculating calories burned through heart rate monitoring is:
Men:
Calories = [(Age × 0.2017) + (Weight × 0.09036) + (Heart Rate × 0.6309) - 55.0969] × Time / 4.184Women:
Calories = [(Age × 0.074) + (Weight × 0.05741) + (Heart Rate × 0.4472) - 20.4022] × Time / 4.184Let’s calculate for a 35-year-old male weighing 80kg, exercising for 30 minutes with an average heart rate of 145 BPM:
Calories = [(35 × 0.2017) + (80 × 0.09036) + (145 × 0.6309) - 55.0969] × 30 / 4.184
= [7.0595 + 7.2288 + 91.4805 - 55.0969] × 30 / 4.184
= 50.6719 × 30 / 4.184
≈ 363 caloriesHow to Calculate Calories Burned by Heart Rate?
The process involves these essential steps:
- Determine Your Maximum Heart Rate (MHR): 220 – Age, A 40-year-old: 220 – 40 = 180 BPM
- Monitor Your Average Heart Rate during exercise using a fitness tracker or heart rate monitor.
- Calculate Your Heart Rate Reserve (HRR): MHR – Resting Heart Rate, If MHR = 180 and RHR = 70: 180 – 70 = 110
- Apply the Calorie Calculation Formula using your specific parameters.
A 28-year-old woman weighing 62kg with a resting heart rate of 65 BPM, exercises for 40 minutes, maintaining an average heart rate of 135 BPM:
MHR = 220 - 28 = 192 BPM
HRR = 192 - 65 = 127 BPM
Calories = [(28 × 0.074) + (62 × 0.05741) + (135 × 0.4472) - 20.4022] × 40 / 4.184
≈ 289 caloriesHow Many Calories Does 150 BPM Burn?
For a 30-minute workout at 150 BPM:
- Average male (75kg): Approximately 400-450 calories
- Average female (60kg): Approximately 300-350 calories
This heart rate typically represents moderate to vigorous exercise intensity, falling within 70-85% of maximum heart rate for most adults.
Is Heart Rate Calories Accurate?
Heart rate-based calorie calculations are generally 80-85% accurate when proper parameters are used.
Factors affecting accuracy include:
- Fitness Level: More fit individuals burn fewer calories at the same heart rate.
- Environmental Conditions: Temperature and humidity affect heart rate.
- Medication: Some medications can influence heart rate.
- Stress Levels: Emotional stress can elevate heart rate without corresponding caloric burn.
