Calories Burned Kayaking at 85 kg — 425 kcal per Hour
Kayaking at 85 kg (176–198 lb) burns about 425 kcal per hour. That figure comes from the activity's MET value of 5 in the 2011 Compendium of Physical Activities, multiplied by body weight: 5 × 85 kg × 1 hour = 425 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.
Kayaking is a seated paddling sport: the paddler sits low in a closed or open boat, drives a double-bladed paddle alternately on each side, and steers with the stroke itself. The work falls mainly on the shoulders, arms and core, with the legs bracing the boat, and the effort rises sharply against wind, current or waves. The Compendium rates kayaking at 5.0 METs, a moderate intensity, the same as stand-up paddleboarding.
It suits people who enjoy being on the water and want upper-body exercise that feels like exploring rather than training. It is low impact, but the shoulders do most of the work, so beginners should start with short outings and build up. The headline number to remember is 425 kcal per hour at 85 kg, or about 212 kcal for a 30-minute session. Everything below is an estimate: MET values are population averages, and your own burn will vary with fitness, technique and conditions. That does not make the numbers useless — it makes them a planning tool, and a good one, as long as you treat them as approximate.
Calculate your own numbers
Use the Calorie calculator to work out your own burn for kayaking 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 Maintenance 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 5 METs therefore uses 5 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, 5, is the one recorded for kayaking in the FitCalc activity data, taken from the 2011 Compendium.
Worked through for this page:
- MET for kayaking: 5
- Body weight: 85 kg (the midpoint of the 80-90 kg band, 176–198 lb)
- Duration: 1 hour
- Calculation: 5 × 85 × 1 = 425 kcal
For a 30-minute session the same calculation is 5 × 85 × 0.5 = 212 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 | 5 × 85 × 0.25 | 106 kcal |
| 30 minutes | 5 × 85 × 0.5 | 212 kcal |
| 45 minutes | 5 × 85 × 0.75 | 319 kcal |
| 60 minutes | 5 × 85 × 1 | 425 kcal |
| 90 minutes | 5 × 85 × 1.5 | 638 kcal |
That is about 7.1 kcal per minute of kayaking at this weight. A short session still counts: even 15 minutes burns 106 kcal, and three 15-minute sessions across a day add up to the same 319 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 | 275 kcal | 138 kcal |
| 65 kg | 325 kcal | 162 kcal |
| 75 kg | 375 kcal | 188 kcal |
| 85 kg | 425 kcal | 212 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 kayaking compares
Here is kayaking against four other activities at the same 85 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 85 kg |
|---|---|---|
| kayaking | 5 | 425 kcal |
| stand-up paddleboarding | 5 | 425 kcal |
| swimming freestyle at a moderate effort | 5.8 | 493 kcal |
| cycling at a leisurely pace (under 10 mph) | 4 | 340 kcal |
| canoeing | 4 | 340 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 kayaking into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 424 kcal | 850 kcal |
| 3 sessions | 636 kcal | 1275 kcal |
| 5 sessions | 1060 kcal | 2125 kcal |
At 5 METs, kayaking counts as moderate-intensity activity, so it counts towards the widely used adult activity target of 150 minutes of moderate activity a week. Five 30-minute sessions a week would meet that target entirely and burn about 1060 kcal a week at 85 kg. Because the intensity is moderate, it can be done most days, and it pairs well with one harder weekly session for variety.
How to use the result
Learn the basic forward stroke before worrying about speed: rotate the torso with each stroke and keep the arms relatively straight, letting the core do the work instead of the shoulders alone. Always wear a personal flotation device, check the weather and water conditions before launching, and tell someone your route on open water. Start with flat, sheltered water for 30 to 45 minutes and build up to longer trips. 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 relaxed day trip often runs two to four hours with breaks, so the total burn for the day can be substantial even at a moderate pace.
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. It also cannot tell you whether the activity is safe for you: if you have a heart condition, joint problems, asthma or any other health concern, check with a healthcare professional before starting a new, intense activity. Use the calorie figure as a planning estimate, and judge the activity by how you feel doing it and whether you keep doing it.
The 5.0 MET figure is an average for kayaking, but the real cost depends on the water: paddling into a headwind or against a current costs far more than drifting downstream, and surf or choppy water adds balance work that the formula does not capture. The figure also says nothing about the shoulders — kayaking is a repetitive overhead-style activity, and poor technique is the usual cause of shoulder soreness — or about water safety, which is a separate matter from fitness.
Frequently asked questions
How many calories do I burn kayaking for 30 minutes at 85 kg?
About 212 kcal. The maths is 5 METs × 85 kg × 0.5 hours = 212 kcal. That is an estimate from the Compendium average — your real burn depends on your fitness, your pace and the conditions. If you weigh more or less than 85 kg, use the weight table above to read your own figure.
Is kayaking good for weight loss?
It can help, but only as part of an overall calorie deficit. At 85 kg, an hour of kayaking burns about 425 kcal, which is a solid contribution, but weight loss still comes from the total balance of food and activity across the week, not from one session. 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.
How does kayaking compare with stand-up paddleboarding?
At 85 kg, kayaking burns about 425 kcal per hour against 425 kcal for stand-up paddleboarding. The two are rated identically by this measure — both 5 METs — so they burn the same estimated calories at the same weight. The difference between them is the kind of activity, not the energy cost. The best choice is usually the one you will actually do several times a week — consistency matters more than a small difference in the hourly rate.
Does the calorie burn change if I weigh more or less than 85 kg?
Yes, directly. Calories = MET × weight in kg × hours, so the burn scales with body weight. At 85 kg the same hour of kayaking burns about 425 kcal; at 85 kg it burns about 425 kcal. The MET value itself does not change with weight — it describes the intensity of the activity.
How accurate is the 5 MET value for kayaking?
It is a population average from the 2011 Compendium of Physical Activities (Ainsworth et al.), which compiled measured energy costs across published studies. The Compendium lists an exact entry for this activity, so the value is not a substitute for a different activity. Individuals still vary by roughly 10–20% around the average because of fitness, body composition, technique and conditions. Treat 425 kcal per hour as a planning estimate, not a precise measurement of your own body.
Is kayaking mainly an upper-body workout?
Mostly, yes. The arms, shoulders and core do the paddling, while the legs brace the boat and help with rotation. That is why kayaking pairs well with a leg-focused activity such as walking, cycling or squats across the week. The calorie figure on this page — about 425 kcal per hour at 85 kg — reflects the whole-body cost, but the muscles that feel it most afterwards are the shoulders and the core.
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.
