Calories Burned Karate at 85 kg — 876 kcal per Hour
Karate at 85 kg (187 lb) burns about 876 kcal per hour. That figure comes from the activity's MET value of 10.3 in the 2011 Compendium of Physical Activities, multiplied by body weight: 10.3 × 85 kg × 1 hour = 876 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.
Karate is the Okinawan art of striking: punches, kicks, knee strikes and blocks, practised as kata (set forms), kihon (basics) and kumite (sparring). A session moves between precise, repeated basics — the same punch thrown a hundred times — and the sharp, explosive exchanges of sparring. The basics build the technique; the sparring builds the fitness, because you must attack, defend and move at full speed against someone doing the same.
At 10.3 METs, karate is one of the highest-burning activities on this site, level with judo and competitive swimming strokes. An hour at this weight burns the figure on this page. That figure describes a full training session with sparring — a gentle kata-only class burns less, and a hard kumite session burns more, so the mix of the class matters as much as the art itself.
Calculate your own numbers
Use the calorie calculator to work out your own burn for karate 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 10.3 METs therefore uses 10.3 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 karate: 10.3
- Body weight: 85 kg (the midpoint of the 80-90 kg band, 176-198 lb)
- Duration: 1 hour
- Calculation: 10.3 × 85 × 1 = 876 kcal
For a 30-minute session the same calculation is 10.3 × 85 × 0.5 = 438 kcal. Nothing else is hidden in the maths — if your weight or duration changes, only those two numbers change.
Your numbers at 85 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 10.3 × 85 × 0.25 | 219 kcal |
| 30 minutes | 10.3 × 85 × 0.5 | 438 kcal |
| 45 minutes | 10.3 × 85 × 0.75 | 657 kcal |
| 60 minutes | 10.3 × 85 × 1 | 876 kcal |
| 90 minutes | 10.3 × 85 × 1.5 | 1313 kcal |
That is about 14.6 kcal per minute of karate at this weight. A short session still counts: even 15 minutes burns 219 kcal, and three 15-minute sessions across a day add up to the same 657 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 | 566 kcal | 283 kcal |
| 65 kg | 670 kcal | 335 kcal |
| 75 kg | 772 kcal | 386 kcal |
| 85 kg | 876 kcal | 438 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 karate compares
Here is karate against four other activities at the same 85 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 85 kg |
|---|---|---|
| Karate | 10.3 | 876 kcal |
| Soccer, competitive | 10.0 | 850 kcal |
| Jumping rope, moderate | 10.0 | 850 kcal |
| Swimming freestyle, vigorous | 9.8 | 833 kcal |
| Boxing | 12.8 | 1088 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 karate into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 876 kcal | 1752 kcal |
| 3 sessions | 1314 kcal | 2628 kcal |
| 5 sessions | 2190 kcal | 4380 kcal |
A typical karate class lasts 60 to 90 minutes: warm-up and stretching, basics in lines, kata practice, then pad work or sparring. A 60-minute class at this weight burns the figure on this page. Kicks are the most expensive techniques — a roundhouse kick uses the whole leg and hip — which is why classes with heavy kicking feel harder than classes built around hand techniques alone. At 10.3 METs, karate 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 karate alone takes about 35 minutes at 85 kg, and 1,000 kcal takes about 69 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 karate in practice:
Kata versus kumite: kumite (sparring) is far more intense than kata, because you react to a live opponent at full speed. Kata is controlled and rhythmic, and while it demands concentration and control, its energy cost per minute is lower. A class split evenly between the two sits in the middle.
Kicking volume: kicks cost more than punches: they move the whole leg, demand balance on one foot, and load the hips. A class with heavy kicking drills — roundhouse, front and side kicks in combination — burns more than a hand-technique class.
Pad work: hitting pads at full power is one of the hardest parts of karate training, because every strike is maximal and the holder keeps you moving. Ten minutes of hard pad work can leave you more tired than half an hour of kata.
Belt level: beginners waste energy with tense, inefficient movement and burn more per technique than black belts. As technique smooths out, the same punch costs less — but by then the training is harder and longer, so the hourly burn stays high.
Practical tips for this activity:
Warm up the hips thoroughly before kicking — leg swings and easy kicks first, full-power kicks only when you are warm, or the groin and hamstrings will remind you.
Keep your guard up even during basics; the habits you build in lines are the habits you keep in sparring.
Practise kata slowly before you practise it fast — speed without control is just flailing, and it is how knees and ankles get hurt.
Start with two classes a week: at 10.3 METs the legs and shoulders need recovery time, and the flexibility work deserves its own days too.
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 85 kg
At 85 kg you sit at the heavier end of the four weight bands on this site, and that shapes how the numbers feel in practice. Your absolute burn is the highest of the four bands — 876 kcal per hour here against 876 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 85 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. Karate's 10.3 METs is an average across kata, basics and sparring. A slow kata session burns far less; a hard kumite session burns more. The figure does not account for your fitness, your weight distribution between muscle and fat, or the style — some styles emphasise deep stances and power, others speed and light contact, and the energy cost differs. It also says nothing about impact on the joints from repeated kicking, or about the contact risk in sparring. Karate is a superb full-body workout, but anyone with a hip, knee or heart condition should start with a basics-and-kata class and get clearance before sparring. 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 karate burn per hour?
At this weight, about 876 kcal per hour, from 10.3 METs × weight × 1 hour. Thirty minutes burns about 438 kcal, 45 minutes about 657 kcal and 90 minutes about 1313 kcal. A kata-only class burns less than that average and a sparring-heavy class burns more — the mix of the session is what decides where you land.
Does karate burn more calories than taekwondo?
At the Compendium level they are rated identically: both karate and taekwondo are listed at 10.3 METs, so the hourly burn at the same weight is the same. In practice a kicking-heavy taekwondo class and a sparring-heavy karate class are equally demanding. Pick the art whose training you enjoy — the difference is in the style, not the calorie count.
Is karate good for weight loss?
It can help, but only as part of an overall calorie deficit. At this weight an hour of karate burns about 876 kcal, which is a substantial 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.
Does kata burn calories, or only sparring?
Kata does burn calories — it is continuous movement with deep stances, controlled breathing and full-body tension — but it burns less per minute than sparring, because there is no opponent forcing you to react at full speed. Think of kata as moderate work and kumite as vigorous work. Both belong in training; the kata builds the technique that makes the sparring possible.
Will karate make me flexible?
Yes, if you train for it. Karate demands hip mobility for kicks and hamstring flexibility for deep stances, and regular classes plus stretching improve both noticeably over months. Flexibility is a use-it-or-lose-it quality, so stretch after class when the muscles are warm, and do not force a stretch into pain — progress comes from consistency, not from pushing through a sharp pull.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men — consult a healthcare professional before a very-low-calorie diet.
