Racket sport calories:
badminton, tennis and table tennis compared

Three racket sports, three very different bills

For a 70 kg player, an hour of table tennis burns about 280 kcal, social badminton about 315 kcal, competitive badminton about 490 kcal and singles tennis about 560 kcal. All three look like light activity from the sideline, yet the repeated sprints, lunges and changes of direction add up quickly.

The ranking comes down to court size, rally length and how much of the hour is actual play. Table tennis is played in a small area with short movements, badminton demands quick bursts and big reaches, and tennis combines long sprints with hard hitting, plus the changeovers and rests that the rules build in.

The numbers below use MET values from the Compendium of Physical Activities. A calculator for each sport applies them to your weight and time.

The formula and MET values by sport

Worked example: a doubles tennis session

A 75 kg player books the court for two hours on a Sunday morning. Between sets, a water break and a long chat, about 90 minutes is real play, and the format is doubles.

The same 90 minutes of singles at 8.0 MET would give 900 kcal, a third higher, because singles means covering the whole court alone.

Badminton: social games versus club play

Badminton gets underrated. A relaxed game with friends, at about 4.5 MET, is gentle but steady. Club-level singles with fast smashes and recoveries reach about 7.0 MET, which is close to a jog at 7 to 8 km/h.

Take a 70 kg player in a competitive 45-minute singles session: 7.0 × 70 × 0.75 = 367.5, about 368 kcal. The same player in a relaxed 45-minute doubles game at 4.5 MET burns about 236 kcal.

• Singles uses the full court and burns noticeably more than doubles.
• Longer rallies increase the average MET; many short rallies with pauses to fetch the shuttle reduce it.
• A 40-minute game at a hall with a shuttle break every few minutes may be only 30 minutes of play.
• Indoor courts are warm, so sweat rates are high, but sweat is not calories.

Table tennis and tennis details

Table tennis, at about 4.0 MET, is the lightest of the three but has hidden merits: it trains reaction time, hand-eye coordination and agility with very little impact. At 70 kg a 90-minute club session still burns about 420 kcal.

Tennis spans the widest range. A casual rally with a friend might sit near 5 MET, while hard singles reaches 8.0 or more. The Compendium's 7.3 MET for general play suits a typical mixed-level match. Because points are short and rests frequent, wearable heart-rate averages often look lower than the court effort feels.

Estimating a real evening session

Take an evening of badminton with friends. You play three games to 21 points, each lasting about 12 minutes, with two-minute breaks, plus a ten-minute warm-up and a few shuttle changes. Actual play is about 36 minutes, or 0.6 hour. For a 70 kg player at the competitive value of 7.0 MET, that is 7.0 × 70 × 0.6 = 294 kcal. At the social value of 4.5 MET it is 4.5 × 70 × 0.6 = 189 kcal.

Counting the full 90 minutes at the competitive rate would give 735 kcal, more than twice as much, so the time you put in matters more than any other input. Keeping a quick note of each game's start and end time on your phone is enough to fix it.

The same method works for tennis sets and table tennis matches. Count the games and rallies, subtract changeovers and long pauses, and treat warm-up as light activity at about 3 to 4 MET.

Racket sports also load the shoulder, elbow and wrist. A proper warm-up, appropriate grip size and a gradual increase in weekly playing time reduce the risk of overuse problems such as tennis elbow.

A final note on level of play. MET tables assume a certain standard, and beginners often work less than they feel, since rallies are shorter and more points are lost quickly. As skill improves, rallies lengthen and players move more efficiently but also play harder, which pushes intensity up. A regular player who moves from social to league standard over a year may find their average MET rising from about 4.5 to about 6.5 for the same hour on court.

Making the estimate realistic

MET values assume continuous play at the stated level. Real sessions have breaks, shuttle retrieval, ball collection, scoring and conversation. A fair rule is to count 70 to 80% of the booked time as play unless you are in a tight league format.

• Record time from first serve to last point, not including warm-up chatter.
• If you play doubles, use the doubles figure even if you cover a lot of ground on your side.
• Drills and coaching sessions are often higher than matches because there are fewer pauses.
• Add a short warm-up with 5 minutes of easy jogging and shoulder mobility to protect joints.

Racket sports are tough on shoulders, wrists and knees. People with joint problems, heart disease or high blood pressure should check with a clinician and build up gradually.
