Cycling Caloriie

1. Enter your "Exercise Time", "Distance", "Bicycle Speed", "Slope (%)", and "Weight".
2. The "Calories Burned" and "Fat Burned" will be displayed.

1. Basic Concept

Calories burned are calculated by "Exercise Intensity × Weight × Time". The formula is:

Calories Burned (kcal) = METs × Weight(kg) × Exercise Time(h)

• METs (Metabolic Equivalent of Task): 1 at rest, varies with exercise intensity
• Weight: in kg
• Time: in hours (divide minutes by 60)

2. METs Reference for Cycling

As a guideline, METs values are determined by speed as follows:

3. Calculation Example

• Weight: 60kg
• Pace: 16-19 km/h (6.0 METs)
• Time: 1 hour

6.0 × 60 × 1 = 360 kcal

4. Considering Slope

Energy expenditure changes with uphill/downhill riding. A simple method is to "adjust METs by slope":

• Uphill: Add +4% × slope(%) to METs (e.g., 5% uphill → +20%)
• Downhill: Subtract -3% × slope(%) from METs (with minimum limit)

5. For More Accurate Calculations

To consider speed, slope, and wind resistance, "physical calculations" can be used.

This involves calculating required power and converting it to "metabolic energy = calories burned" using human efficiency (about 20-25%). However, the formulas are complex, so it's typically handled by apps or cycling computers.

Summary

• Simplest method: METs × Weight × Time
• With slope: Apply slope adjustment to METs
• Advanced method: Use physical models (power calculations)

Would you like me to prepare web calculator code that automatically calculates calories based on "weight, speed, time, and slope" inputs?
