Heart Rate Calorie Burn Calculator (VO2max Unknown)

Calculate Your Calorie Burn

Estimate your exercise calorie burn based on heart rate, age, gender, and weight without needing your VO2max. Perfect for tracking fitness and optimizing workouts, this tool helps you understand energy expenditure efficiently.

Formula:

The formulas used are widely recognized for estimating calorie expenditure based on heart rate, age, weight, and exercise duration, adapted from research on energy expenditure:

For Men: Calorie Burn = ((-55.0969 + (0.6309 × HR) + (0.1988 × W) + (0.2017 × A)) / 4.184) × D

For Women: Calorie Burn = ((-20.4022 + (0.4472 × HR) + (0.1263 × W) + (0.074 × A)) / 4.184) × D

Where:

  • HR = Average Heart Rate (beats per minute)
  • W = Weight (kilograms)
  • A = Age (years)
  • D = Exercise Duration (minutes)
  • 4.184 = Conversion factor (from Joules to Calories, based on standard assumptions)
