Tennis MET values vary by intensity: doubles (general) = 6.0, singles (recreational) = 7.3, singles (competitive) = 9.0-12.0. Metabolic cost scales with body mass and playing time.
kcal = MET × body_mass(kg) × duration(hours)In a typical match, actual rally time is only 20-30% of total elapsed time. However, recovery periods between points still elevate metabolic rate above resting. Use total court time, not just rally time, for calorie estimates.

75 kg player in a casual singles match with moderate rallying.
→ ~548 kcal
70 kg competitive club player in an intense match.
→ ~1,050 kcal
Doubles tennis has significantly less court coverage and lower intensity (MET ~6.0 vs 7.3-10+). Always specify match format for accurate estimates.
Subtract extended rest periods (changeover conversations, rain delays). Use actual on-court active time for MET calculations.
Estimate energy expenditure from tennis based on match intensity and playing duration. Tennis burns between 400-700+ kcal per hour depending on singles vs doubles, competitive intensity, and player weight.
