Estimate calories and kilojoules burned practising kendo, the Japanese martial art of swordsmanship fought with bamboo swords (shinai) and protective armour (bogu), based on your body weight, training drill, and session length. This calculator uses three kendo-specific MET tiers drawn directly from the Sports section of the 2024 Adult Compendium of Physical Activities — kihon-keiko basic technique practice, kirikaeshi repetitive striking drills, and kakari-geiko all-out attack drills. This page is separate from MegaCalcOnline's general Martial Arts Calorie Calculator, which uses broader novice/moderate-training MET buckets covering styles such as judo, karate, kickboxing, taekwondo and Muay Thai — the MET codes used here are kendo-specific and don't overlap with that page.
Kendo calorie burn is estimated with calories = MET × body weight (kg) × duration (hours), using three kendo-specific MET values from the Sports section of the 2024 Adult Compendium of Physical Activities: kihon-keiko style, moderate intensity (MET 6.5), kirikaeshi style, high intensity (MET 9.6), and kakari-geiko style, very high intensity (MET 11.3). A 70 kg practitioner over a 45-minute session burns around 341 kcal (about 1,428 kJ) doing kihon-keiko, around 504 kcal (about 2,109 kJ) doing kirikaeshi, and around 593 kcal (about 2,482 kJ) doing kakari-geiko. All three MET values are literature-supported figures in the Compendium, none flagged as estimated.

The calculation uses a MET (Metabolic Equivalent of Task) value for your kendo drill, your body weight, and how long you trained. This calculator uses three MET tiers taken directly from the Sports section of the 2024 Adult Compendium of Physical Activities — kihon-keiko style, moderate intensity (code 15444, MET 6.5), kirikaeshi style, high intensity (code 15445, MET 9.6), and kakari-geiko style, very high intensity (code 15446, MET 11.3). Because kendo sessions and drills are usually measured in minutes rather than hours, the calculator takes your minutes input and converts it to hours (hours = minutes ÷ 60) before applying the formula.
| Kendo Drill | MET | Calories (70 kg, 45 min) | Kilojoules |
|---|---|---|---|
| Kihon-keiko style, moderate intensity | 6.5 | 341 kcal | 1,428 kJ |
| Kirikaeshi style, high intensity | 9.6 | 504 kcal | 2,109 kJ |
| Kakari-geiko style, very high intensity | 11.3 | 593 kcal | 2,482 kJ |
Kendo — literally "the way of the sword" — is a modern Japanese martial art descended from traditional swordsmanship, practised as a full-contact sport in which two competitors strike designated target areas using a shinai, a sword-shaped weapon made from four bamboo slats bound together. Practitioners wear bogu, a set of protective armour comprising a helmet with a metal grille (men), padded gloves (kote), a chest and abdomen protector (dō), and a waist and hip guard (tare), which allows full-speed strikes to be delivered and received safely. Kendo places heavy emphasis on posture, footwork, timing and a disciplined, ritualised approach to training, alongside the physical demands of repeated explosive strikes and rapid forward-and-back movement.
Kihon-keiko is fundamentals practice — footwork, stance, grip and basic strikes (men, kote, dō) drilled at a controlled, moderate pace, usually without a resisting opponent applying full pressure. It's the technical backbone of every class and typically opens a session once the warm-up is done. Kirikaeshi steps the pace up considerably: a practitioner advances on a partner delivering a fast, continuous sequence of diagonal strikes to the men (head) target while moving forward, then retreats while striking again, repeating the sequence for a sustained, high-intensity burst that also builds wrist and shoulder conditioning. Kakari-geiko is the most demanding of the three — an all-out attack drill in which one practitioner attacks continuously and explosively for a short, exhausting interval (often 30 to 60 seconds at a time) against a senior partner who receives the strikes and controls the pace, pushing the attacking practitioner close to their physical limit before a brief recovery and repeat.
The table below holds the drill constant at kirikaeshi, high intensity (MET 9.6) for a 45-minute session, so you can see how much body weight alone changes the total.
| Body Weight | MET | Calories (45 min) | Kilojoules |
|---|---|---|---|
| 55 kg | 9.6 | 396 kcal | 1,657 kJ |
| 65 kg | 9.6 | 468 kcal | 1,958 kJ |
| 75 kg | 9.6 | 540 kcal | 2,259 kJ |
| 85 kg | 9.6 | 612 kcal | 2,561 kJ |
| 95 kg | 9.6 | 684 kcal | 2,862 kJ |
Kihon-keiko blocks, kirikaeshi drills and kakari-geiko intervals all run to different lengths within a class. Here body weight is fixed at 70 kg while session length and drill both change, so you can compare how much a longer session and a harder drill each add to the total.
| Session Length | Kihon-keiko (MET 6.5) | Kirikaeshi (MET 9.6) | Kakari-geiko (MET 11.3) |
|---|---|---|---|
| 15 minutes | 114 kcal / 476 kJ | 168 kcal / 703 kJ | 198 kcal / 827 kJ |
| 30 minutes | 228 kcal / 952 kJ | 336 kcal / 1,406 kJ | 396 kcal / 1,655 kJ |
| 45 minutes | 341 kcal / 1,428 kJ | 504 kcal / 2,109 kJ | 593 kcal / 2,482 kJ |
| 60 minutes | 455 kcal / 1,904 kJ | 672 kcal / 2,812 kJ | 791 kcal / 3,310 kJ |
Australian nutrition panels list energy in kilojoules, not calories, so it's worth converting your session total into the same unit your food packaging uses. Multiply your calorie figure by 4.184 to get kilojoules. A 70 kg practitioner doing a 45-minute kakari-geiko session burns about 593 kcal, which is roughly 2,482 kJ — a useful figure to weigh up against the energy value of a post-training meal or recovery snack.
How many calories does kendo burn?
It depends on the drill and session length. Using this calculator's three tiers for a 70 kg practitioner over a 45-minute session: kihon-keiko, moderate intensity (MET 6.5) burns about 341 kcal (1,428 kJ), kirikaeshi, high intensity (MET 9.6) burns about 504 kcal (2,109 kJ), and kakari-geiko, very high intensity (MET 11.3) burns about 593 kcal (2,482 kJ). Lighter or heavier practitioners, and shorter or longer sessions, will see proportionally lower or higher totals, so enter your own weight and session length above for a personalised estimate.
How is calories burned kendo calculated?
The calculator multiplies a MET (Metabolic Equivalent of Task) value for your kendo drill by your body weight in kilograms and your session duration in hours: calories = MET × body weight (kg) × duration (hours). Because kendo sessions are usually measured in minutes, the calculator takes your minutes input and divides by 60 before running the formula. The three MET values used — 6.5 for kihon-keiko style, moderate intensity (code 15444), 9.6 for kirikaeshi style, high intensity (code 15445), and 11.3 for kakari-geiko style, very high intensity (code 15446) — come directly from the Sports section of the 2024 Adult Compendium of Physical Activities. The kilocalorie result is then multiplied by 4.184 to give the equivalent figure in kilojoules, the unit used on Australian food labels.
What's the difference between kihon-keiko, kirikaeshi and kakari-geiko?
All three are recognised kendo training drills, but they load the body very differently. Kihon-keiko is basic technique practice — footwork, posture and fundamental strikes performed at a controlled, moderate pace, usually the foundation of any class. Kirikaeshi is a repetitive striking drill where a practitioner delivers a fast sequence of diagonal strikes (men-uchi) while advancing and retreating with a partner, raising the pace to a high-intensity effort. Kakari-geiko is an all-out attack drill in which one practitioner attacks continuously and explosively for a short, exhausting burst while a senior partner receives the strikes, making it the most physically demanding of the three, at very high intensity.
Does body weight affect how many calories kendo burns?
Yes. Because calories equal MET multiplied by body weight in kilograms multiplied by duration in hours, body weight is a direct multiplier in the formula. At the kirikaeshi tier (MET 9.6) for a 45-minute session, a 95 kg practitioner burns roughly 684 kcal compared with about 396 kcal for a 55 kg practitioner completing the identical drill for the identical time.
What are the limitations of this calorie estimate?
This calculator uses three published, literature-supported MET values multiplied by your body weight and session time, which gives a solid population-level estimate rather than a personalised one. It doesn't account for your individual fitness level, technique or skill, how much of a real class was spent in low-intensity instruction versus drilling, or the extra load of sparring (jigeiko) or grading. It also can't measure your actual heart rate or effort during a session. Use the result as a reasonable planning figure, and choose whichever of the three drill tiers best matches how your session actually felt.
Is kendo a good workout?
Yes, particularly once drills move beyond basic technique practice. All three MET values used on this page sit at moderate intensity or above, and both kirikaeshi (MET 9.6) and kakari-geiko (MET 11.3) rate as vigorous-intensity exercise, comparable to running or a hard interval session, once the repetitive striking, explosive footwork and sustained cardiovascular demand are factored in. Even kihon-keiko at MET 6.5 is genuine moderate-to-vigorous activity, meaning a typical kendo class delivers a real cardio and full-body workout alongside its technical and disciplinary demands.
How does this Kendo Calculator differ from the site's Martial Arts Calorie Calculator?
They cover different ground on purpose. Our Martial Arts Calorie Calculator uses two broad, pace-based MET values (novice/practice at MET 5.3, and a moderate training pace at MET 10.3) that combine several striking and grappling styles — judo, karate, kickboxing, taekwondo and Muay Thai — into a single general-purpose estimate. This Kendo Calculator instead uses three kendo-specific MET codes from the Compendium's Sports section (6.5, 9.6 and 11.3) tied to named kendo drills — kihon-keiko, kirikaeshi and kakari-geiko — so if you specifically practise kendo, this page gives a more precise, drill-matched estimate than the general martial arts tool.
What does a typical kendo class involve?
A typical kendo class usually opens with a warm-up and solo footwork or swinging practice (suburi), followed by kihon-keiko to drill fundamental strikes and posture. Students then pair up in bogu (men, kote, dō & tare) for drills such as kirikaeshi and, in more advanced sessions, kakari-geiko or free sparring (jigeiko), before a formal, disciplined close. Because a single class moves through several of these stages, your actual energy expenditure over a full session will usually sit somewhere between the calculator's three individual drill tiers rather than matching just one of them for the whole class.
