1. What is the Bicycling Calories Equation?

The bicycling calories equation estimates energy expenditure based on distance cycled, speed, MET value, and body weight. It provides a scientifically validated method to calculate calories burned during cycling activities.

2. How Does the Calculator Work?

The calculator uses the bicycling calories equation:

Where:

• \( Distance \) — Distance cycled in kilometers
• \( Speed \) — Average cycling speed in km/h
• \( MET \) — Metabolic equivalent of task (cycling intensity)
• \( Weight \) — Body weight in kilograms
• 60 — Converts hours to minutes
• 3.5 — Oxygen consumption at rest (mL/kg/min)
• 200 — Conversion factor to kcal

Explanation: The equation calculates time spent cycling from distance and speed, then applies standard metabolic calculations based on intensity (MET) and body weight.

3. Importance of Calorie Calculation

Details: Accurate calorie estimation helps with weight management, training planning, and understanding energy expenditure during exercise.

4. Using the Calculator

Tips: Enter distance in km, speed in km/h, appropriate MET value (default 7.5 for moderate cycling), and weight in kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for cycling?
A: Light cycling (10-12 km/h): 4-6 MET; Moderate (15-20 km/h): 7-10 MET; Vigorous (>20 km/h): 10-16 MET.

Q2: How accurate is this calculation?
A: It provides a good estimate (±10-20%) for steady-state cycling. Actual calories may vary based on terrain, wind, and bike efficiency.

Q3: Should I use my gross or net weight?
A: Use your total body weight. The calculation already accounts for basal metabolic rate through the MET value.

Q4: Does this account for hills or resistance?
A: No, for hilly terrain use a higher MET value to compensate for increased effort.

Q5: Can I use this for stationary biking?
A: Yes, but ensure you use accurate distance/speed measurements from your stationary bike's computer.
