Exercise Calorie Calculator

The amount of calories burned during exercise depends on various factors such as your weight, activity type, intensity, and duration. This calculator helps you estimate the calories burned based on these factors.

What is MET?

MET (Task Metabolic Equivalent), is a measure of energy expenditure. One MET is equal to the energy used when sitting quietly. Higher MET values indicate more calories burned.

For example, walking at a moderate pace has a MET value of 3.5, while running at 8 mph has a MET value of 11.5.

Calories Burned Calculation

Calories burned during exercise are calculated using the MET value, your weight, and the duration of the activity. The formula takes into account the intensity of the exercise.

For example, a 70kg person walking at a moderate pace (MET 3.5) for 1 hour would burn approximately 245 calories (3.5 × 70 × 1 = 245 kcal).

Exercise Intensity

Exercise intensity affects the MET value and, consequently, the calories burned. Higher intensity activities burn more calories per minute than lower intensity activities.

• Low intensity: Activities that are easy to perform and don't cause significant increase in heart rate (e.g., slow walking, gentle stretching).
• Moderate intensity: Activities that cause noticeable increase in heart rate and breathing (e.g., brisk walking, light jogging).
• High intensity: Activities that cause significant increase in heart rate and breathing (e.g., running, swimming laps).
• Very high intensity: Activities that cause maximum heart rate and breathing (e.g., sprinting, high-intensity interval training).

Factors Affecting Calorie Burn

Several factors can influence the number of calories burned during exercise:

• Age: Younger individuals typically burn more calories due to higher metabolic rates.
• Weight: Heavier individuals burn more calories performing the same activity.
• Fitness level: More fit individuals may burn fewer calories doing the same activity due to increased efficiency.
• Environmental factors: Temperature, altitude, and terrain can affect calorie burn.

Limitations

This calculator provides general estimates based on general formulas and assumptions. Individual calorie burn can significantly vary based on fitness level, body composition, technical and environmental factors. The calculator does not account for all these variables.

• Individual variations: Results may vary significantly between individuals due to factors like metabolism, muscle mass, and exercise efficiency.
• Accuracy limitations: The calculator uses average MET values and may not account for variations in exercise technique or intensity.
• Afterburn effect: The calculator does not account for the additional calories burned after exercise (EPOC - Excess Post-exercise Oxygen Consumption).
