Martial Arts Calories Calculator
Calculate calories burned during martial arts training including karate, judo, boxing, MMA, and Brazilian Jiu-Jitsu by session duration and intensity.
How martial arts calorie burn is calculated:
Calorie burn during exercise is estimated using MET values (Metabolic Equivalent of Task). One MET equals the energy your body burns at rest. Higher MET values mean more intense activity.
The formula:
Calories = MET × Body weight (kg) × Duration (hours)
MET values by martial art and intensity:
| Activity | MET (moderate) | MET (vigorous) |
|---|---|---|
| Karate / Taekwondo | 5.0 | 10.0 |
| Judo / Wrestling | 6.0 | 10.0 |
| Boxing (sparring) | 6.0 | 12.0 |
| Boxing (heavy bag) | 5.5 | 9.0 |
| Brazilian Jiu-Jitsu | 5.0 | 8.0 |
| MMA (training) | 6.0 | 10.0 |
| Muay Thai | 6.0 | 11.0 |
| Tai Chi | 3.0 | 5.0 |
| Krav Maga | 6.0 | 10.5 |
Worked example:
A 75 kg person doing vigorous boxing sparring for 60 minutes:
- Calories = 12.0 × 75 × 1.0 = 900 calories
The same person doing moderate Tai Chi for 60 minutes:
- Calories = 3.0 × 75 × 1.0 = 225 calories
Typical session calorie ranges (150 lb / 68 kg person, 1 hour):
- Tai Chi class: 200–350 cal
- BJJ or karate class: 350–700 cal
- Boxing sparring or MMA training: 500–850 cal
- Intense Muay Thai session: 600–900 cal
Factors that increase burn:
- Higher bodyweight burns more total calories
- Sparring burns 30–50% more than drills or forms
- Grappling arts (BJJ, judo, wrestling) are full-body sustained effort
- Hot environments increase heart rate but not necessarily calorie burn
Recovery note: High-intensity martial arts sessions create an “afterburn” effect (EPOC) — your metabolism stays elevated for 12–24 hours after intense sparring or rolling. The calculator shows session calories only.
