                          - Light (Casual play): Gentle rallying, minimal running
 
                          - Moderate (Average play): Regular rallying, some running and jumping
                          - High (Intense play): Fast-paced game with lots of running, jumping, and quick movements

                Understanding the Results
                The calculator provides two results:
                
                    - Estimated Calories Burned: Total calories burned based on your inputs
 
                    - Estimated Calories Burned Per Hour: Your calorie burn rate if you maintained the same intensity for an hour
 
                
                
                Factors Affecting Calorie Burn
                Your actual calorie burn may vary based on:
                
                    - Your skill level and playing style
 
                    - Surface type (hard court vs. grass)
 
                    - Weather conditions
 
                    - Rest periods during play
 
                    - Individual metabolic rate
 
                
                
                Example
                For a 70 kg person who plays badminton for 60 minutes at a moderate intensity:
                Calories burned = 5.0 METs × 70 kg × (60/60) hours = 350 calories
