What this jumping rope calorie calculator does
This calculator estimates calories burned during jumping rope using the MET (Metabolic Equivalent of Task) formula - the gold standard used by exercise physiologists and the 2011 Compendium of Physical Activities. Enter your body weight and how long you exercised; the calculator multiplies the activity's MET value by your weight (kg) and time (hours) to estimate kcal burned. Higher intensity = higher MET = more calories burned per minute.
Intensity guide for accurate results
Pick the intensity that matches what you actually did - not what you wished you did. Each jumping rope intensity has a specific MET value from peer-reviewed research. If you alternated paces (e.g., interval training), pick the average. For more precise tracking, use a heart rate monitor and the Heart Rate Calorie Calculator on HisabWeb - it accounts for individual cardiovascular response, which the MET method approximates.
What is MET (Metabolic Equivalent)?
MET = the energy cost of an activity relative to sitting quietly. 1 MET ≈ 3.5 mL O2 per kg of body weight per minute, or approximately 1 kcal per kg per hour at rest. Sitting = 1 MET; walking slowly = ~2.5 MET; running fast = ~13 MET. The Compendium of Physical Activities (Ainsworth et al., 2011) catalogs 821 activities with their MET values from oxygen-consumption studies. Multiplying MET × weight × time gives a robust calorie estimate for adults.
Why body weight matters
Heavier bodies burn more calories doing the same activity - more mass to move means more energy. A 90 kg person burns ~29% more calories than a 70 kg person doing the same workout. The MET formula scales linearly with weight, so accurate weight input is critical. Tip: use your current weight, not your goal weight, for the most realistic estimate.
Accuracy & limitations
MET estimates typically come within ±15-20% of metabolic-cart-measured values for moderate-intensity activities. Sources of variability: individual VO2max, body composition (more muscle = higher BMR), exercise efficiency (trained athletes burn fewer calories at the same speed), terrain, equipment, and even temperature. For more precision, use a heart-rate-based estimate (Keytel formula) or a metabolic cart in a lab.
Frequently asked questions
Pound for pound, jump rope can burn slightly MORE calories than running at moderate pace (jumping at 120/min = MET 11.8 vs running 6 mph = MET 9.8). It's also more time-efficient and portable. The downside: harder on joints (high impact) and skill takes practice. 10 minutes of jump rope ≈ 20-25 minutes of moderate running for total calories.
About 175-260 kcal depending on weight and pace. A 70 kg person at moderate pace (MET 11.8) burns ~206 kcal in 15 minutes. At fast pace (MET 12.3) ~215 kcal. The exact number depends on your weight - heavier people burn more for the same workout.
Yes for beginners - try 30 seconds on, 30 seconds rest for 10 rounds (5 min total). As fitness builds, extend to 1-2 min sets with 30 sec rest, or do continuous 5-15 min sessions. Rest prevents form breakdown and lets you maintain a higher intensity per set - more total calories than dragging out a single long set.
