How We Calculate Calories Burned for Racquetball in Rockford
Our calculator uses the standard MET (Metabolic Equivalent of Task) formula with a local climate adjustment for Rockford:
Calories = MET × Weight (kg) × Duration (hrs) × Climate Factor
= 7 × Weight (kg) × Duration (hrs) × 1.03
The MET value of 7 for racquetball is sourced from the Compendium of Physical Activities. The climate factor of 1.03 accounts for Rockford's average temperature of 53°F. Research shows that exercising in non-neutral temperatures increases energy expenditure as the body works to maintain its core temperature.
Racquetball is an indoor sport played in an enclosed court where the ball can be played off all four walls, ceiling, and floor. The enclosed space means the ball stays in play longer, resulting in more continuous movement and higher calorie burn than many other racket sports. Players must constantly sprint, lunge, twist, and dive to return shots from unpredictable angles. A typical game involves intense bursts of activity that build anaerobic fitness, agility, and hand-eye coordination.
