Calories Burned Playing water polo at 65 kg — 650 kcal per Hour
Water polo at 65 kg (143 lb) burns about 650 kcal per hour. That figure comes from the activity's MET value of 10.0 in the 2011 Compendium of Physical Activities, multiplied by body weight: 10.0 × 65 kg × 1 hour = 650 kcal. This page works the numbers out in full — for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight — so you can plan sessions with real figures instead of guessing.
Water polo is handball played in deep water: swim, tread water, pass, shoot and wrestle for position, all without ever touching the bottom of the pool. There is no standing still in water polo — when you are not swimming, you are treading water with an eggbeater kick, and when you are not treading, you are fighting for position against an opponent who is trying to push you under. It is swimming, wrestling and ball skills at the same time.
At 10.0 METs, water polo is one of the highest-burning activities on this site, level with competitive soccer and just below judo. An hour at this weight burns the figure on this page. The water hides the effort — you do not sweat visibly and there is no impact — but the heart rate during a game is typically as high as in any land sport, and most players are exhausted after four quarters.
Calculate your own numbers
Use the calorie calculator to work out your own burn for playing water polo at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the running calorie calculator to see how this session fits into your total daily energy use.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575–1581):
Calories (kcal) = MET × body weight (kg) × duration (hours)
One MET is the energy you use sitting quietly at rest — about 1 kcal per kilogram of body weight per hour. An activity rated at 10.0 METs therefore uses 10.0 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here is the one recorded for this activity in the FitCalc activity data, taken from the Compendium.
Worked through for this page:
- MET for playing water polo: 10.0
- Body weight: 65 kg (the midpoint of the 60-70 kg band, 132-154 lb)
- Duration: 1 hour
- Calculation: 10.0 × 65 × 1 = 650 kcal
For a 30-minute session the same calculation is 10.0 × 65 × 0.5 = 325 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 65 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 10.0 × 65 × 0.25 | 162 kcal |
| 30 minutes | 10.0 × 65 × 0.5 | 325 kcal |
| 45 minutes | 10.0 × 65 × 0.75 | 488 kcal |
| 60 minutes | 10.0 × 65 × 1 | 650 kcal |
| 90 minutes | 10.0 × 65 × 1.5 | 975 kcal |
That is about 10.8 kcal per minute of playing water polo at this weight. A short session still counts: even 15 minutes burns 162 kcal, and three 15-minute sessions across a day add up to the same 488 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same — it describes the activity, not the person — but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 550 kcal | 275 kcal |
| 65 kg | 650 kcal | 325 kcal |
| 75 kg | 750 kcal | 375 kcal |
| 85 kg | 850 kcal | 425 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected — it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How playing water polo compares
Here is playing water polo against four other activities at the same 65 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 65 kg |
|---|---|---|
| Water polo | 10.0 | 650 kcal |
| Soccer, competitive | 10.0 | 650 kcal |
| Jumping rope, moderate | 10.0 | 650 kcal |
| Swimming freestyle, vigorous | 9.8 | 637 kcal |
| Running at 6 mph | 9.8 | 637 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week — one harder session, two easier ones — is usually more sustainable than doing the hardest activity every time.
Fitting playing water polo into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 650 kcal | 1300 kcal |
| 3 sessions | 975 kcal | 1950 kcal |
| 5 sessions | 1625 kcal | 3250 kcal |
A typical water polo session lasts 60 to 90 minutes: swimming warm-up, passing and shooting drills, then a scrimmage or match in four quarters with short breaks. A 60-minute session at this weight burns the figure on this page. The eggbeater kick — the alternating circular leg movement that holds you up — is the foundation skill, and until it is automatic, treading water alone is exhausting. At 10.0 METs, playing water polo counts as vigorous activity, so it contributes directly towards the widely used target of 150 minutes of moderate activity a week for adults. To burn 500 kcal from playing water polo alone takes about 47 minutes at 65 kg, and 1,000 kcal takes about 93 minutes — spread across the week, that is far more realistic than trying to do it in one session. Build up gradually — add 10% to your weekly total at most, and keep at least one rest day.
How to use the result
What changes the burn for playing water polo in practice:
Game versus drills: a real game burns more than a drills session, because the pace is set by the opposition and there is no slowing down when you are tired. Drills let you control the effort; a game does not.
Position: field players swim the length of the pool repeatedly and burn the most. Goalkeepers tread water and react, which is hard in a different way but involves less swimming, so their hourly burn is usually lower.
Eggbeater efficiency: beginners waste enormous energy treading water, because the eggbeater kick is not yet automatic. As the kick becomes efficient, treading costs less — but by then you are swimming more and playing harder, so the hourly burn stays high.
Water temperature: cold water raises the energy cost slightly, because the body works to stay warm, and it also makes the muscles stiffer. Warm water is kinder on the muscles but can feel more tiring over a long session.
Practical tips for this activity:
Learn the eggbeater kick before anything else — it is the skill that makes the rest of the game possible, and it takes weeks to become automatic.
Practise treading water with your hands out of the water; if you can stay up with just your legs, you have the foundation for passing and shooting.
Wear a proper water polo cap with ear guards — ears are the most commonly injured body part in the sport, and the cap exists for a reason.
Start with two sessions a week: at 10.0 METs the shoulders and legs need recovery, and the eggbeater kick alone is enough to make beginners sore.
Use the numbers on this page to set realistic expectations rather than to chase a daily total. If you are tracking food as well, add the session's calories to your total daily energy expenditure for that day, and remember that the figure is an estimate with roughly 10–20% uncertainty. Do not eat back every calorie the calculator shows: activity trackers and MET estimates both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest — 300–500 kcal a day is a common, sustainable range — and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
A note at 65 kg
At 65 kg you sit in the middle of the four weight bands on this site, and that shapes how the numbers feel in practice. Your absolute burn is between the lightest and heaviest bands — 650 kcal per hour here against 850 kcal at 85 kg — but your burn per kilogram of body weight is identical, because the MET formula is linear: every kilogram costs the same. In practical terms that means duration and frequency matter more for you than for a heavier person doing the same activity if you are lighter, and less if you are heavier. Two 45-minute sessions will usually serve you better than one 90-minute session, because you accumulate the same total with less fatigue in each outing, and you are less likely to run into the joint and muscle soreness that long sessions cause. If you are tracking weight loss, remember that a smaller body also means a smaller total daily expenditure, so a 300–500 kcal deficit is a larger share of your day than it is for someone heavier — keep the deficit at the modest end of that range and let the activity do its work over weeks, not days.
What the number does NOT tell you
The MET formula is honest about what it measures and silent about the rest. It does not account for your fitness level: a fit person burns fewer calories doing the same activity than an unfit person, because their body is more efficient. It does not account for body composition — two people at 65 kg with different amounts of muscle and fat will burn slightly different amounts. It does not include the afterburn (excess post-exercise oxygen consumption) that follows hard sessions, it does not measure strength, flexibility or balance gained, and it says nothing about how the activity affects your appetite, sleep or mood. Water polo's 10.0 METs assumes a normal session of drills and game play. A gentle passing session burns less; a full match burns more. The figure does not account for your swimming fitness, your eggbeater efficiency, or your position — goalkeepers burn less than field players. It also says nothing about the sport's physical demands: shoulders take a beating from throwing, ears from contact, and the water hides dehydration, so players often drink far less than they need. Water polo is a superb full-body workout with no impact, but anyone with a shoulder or heart condition should get clearance and build up gradually before playing a full match. Use the calorie figure as a planning estimate, and judge the activity by how you feel doing it and whether you keep doing it.
Frequently asked questions
How many calories does water polo burn per hour?
At this weight, about 650 kcal per hour, from 10.0 METs × weight × 1 hour. Thirty minutes burns about 325 kcal, 45 minutes about 488 kcal and 90 minutes about 975 kcal. A full match sits at the top of that range and a gentle drills session at the bottom — the mix of the session is what decides the real figure.
Is water polo good for weight loss?
It can help, but only as part of an overall calorie deficit. At this weight an hour of water polo burns about 650 kcal, which is a large contribution — but weight loss comes from the total balance of food and activity across the week. Aim for a gradual loss of 0.5–1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
Do I need to be a strong swimmer to play water polo?
You need to be a confident swimmer, yes. You must be able to swim the length of the pool repeatedly and tread water for long periods without touching the bottom. You do not need to be a fast swimmer — the eggbeater kick and ball skills matter more than freestyle speed — but if you cannot yet swim 200 metres comfortably, build that first and add water polo later.
Why is water polo so tiring if there is no running?
Because you never get to stand still. Treading water is continuous work for the legs, swimming is continuous work for the arms and legs, and wrestling for position adds bursts of maximal effort on top. The water also hides the sweat, so players often do not realise how hard they are working until the fourth quarter, when the legs simply stop responding.
Does water polo build upper-body strength?
Yes — throwing, passing and wrestling for position build the shoulders, chest and arms, while the eggbeater kick builds the legs. It is one of the most complete full-body workouts in any sport, with the added advantage of zero impact on the joints. The shoulders do take a heavy load, so warm them up properly and build throwing volume gradually.
