Calories Burned Jumping rope at a slow pace at 55 kg — 484 kcal per Hour

calories burned jumping rope at a slow pace 55kg — the short answer is 484 kcal per hour. That figure is for a 55 kg (121 lb) person jumping rope at a slow pace at the intensity the 2011 Compendium of Physical Activities assigns to it, and this page works the number out in full so you can check it, scale it to any session length, and see how it compares with other activities at the same body weight.

The headline number is an estimate, not a measurement of your body. Two people of the same weight doing the same activity for the same hour will burn different amounts, because fitness, technique, temperature, and how hard they actually push all move the real figure. What the formula gives you is a fair, standardised comparison — the same method researchers use when they rank activities by energy cost — and that is exactly what it is useful for: comparing options, planning a week, and setting a realistic expectation before you start.

Jumping rope at a slow pace is the gentle way into one of the most efficient exercises there is. The jumps are low, the rhythm is relaxed — roughly one bounce per step, with both feet leaving the ground together — and the rope turns slowly enough that you can hold a conversation between jumps. It is the pace for beginners, for warm-ups, and for anyone coming back to exercise after time away.

Slow does not mean easy. Even at a slow pace, jumping rope is 8.8 METs — vigorous exercise by any classification — because every jump is a small plyometric effort from the calves, and the arms, shoulders and core work continuously to keep the rope turning. The low impact of small jumps keeps it joint-friendly, but the cardiovascular demand is real from the first minute.

Work out your own number

Use the calorie calculator to get your own daily figure: it combines your basal metabolic rate with your activity level and your goal, so a single activity session slots into a full-day picture instead of floating on its own. If you want the activity alone at your exact weight rather than the 55 kg worked example on this page, the running calorie calculator takes any weight and duration and applies the same MET method. Both tools show their working, and both label their results as estimates.

The formula, shown and cited

The calculation comes from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8):1575–1581), which assigns every activity a MET value — a multiple of your resting metabolic rate. One MET is the energy you use sitting quietly. The formula is:

Calories per hour = MET × body weight (kg)

For this page the MET value for jumping rope at a slow pace is 8.8, which makes it a vigorous-intensity activity by the usual classification (under 3 METs is light, 3 to 6 is moderate, above 6 is vigorous). The worked example uses the midpoint of the 50-60 kg band, 55 kg:

8.8 MET × 55 kg = 484 kcal per hour

For any other duration, multiply by the hours: calories = MET × weight (kg) × hours. A 30-minute session is half the hourly figure, a 90-minute session is one and a half times it, and the table below does that arithmetic for the common session lengths so you do not have to.

Your numbers at 55 kg

Session length Calculation Calories burned
15 minutes 8.8 × 55 × 0.25 121 kcal
30 minutes 8.8 × 55 × 0.50 242 kcal
45 minutes 8.8 × 55 × 0.75 363 kcal
60 minutes 8.8 × 55 × 1.00 484 kcal
90 minutes 8.8 × 55 × 1.50 726 kcal
120 minutes 8.8 × 55 × 2.00 968 kcal

A useful way to read the table is backwards: to burn roughly 500 kcal from jumping rope at a slow pace alone at 55 kg you would need about 62 minutes. Three one-hour sessions a week come to about 1,452 kcal a week from this activity, and five 45-minute sessions come to about 1,815 kcal a week. Those weekly totals are the numbers that matter for weight management, because a single session is a small fraction of a week's energy balance — consistency across weeks is what moves body weight, not one heroic session.

Note also that the table scales linearly with weight. A heavier person burns more doing the same activity for the same time, because there is more body to move; a lighter person burns less. That is not a judgement about fitness — it is physics, and it is why every calories-burned figure on this site states the weight it was calculated at. If you weigh 10 kg more than the 55 kg example, add roughly 88 kcal per hour; 10 kg less, subtract the same.

How the number changes with body weight

Weight band Midpoint kcal per hour kcal per 30 minutes
50-60 kg 55 kg (121 lb) 484 242
60-70 kg 65 kg (143 lb) 572 286
70-80 kg 75 kg (165 lb) 660 330
80-90 kg 85 kg (187 lb) 748 374

The band table is the quickest way to find your own figure without doing the multiplication. Find the band your weight falls in, take its midpoint, and read across: that is the hourly burn the Compendium method gives for jumping rope at a slow pace at your weight. If you sit on a boundary — exactly 60, 70 or 80 kg — either neighbouring band is a fair estimate, and the difference between them is small: at 8.8 METs, each 10 kg of body weight is worth about 88 kcal an hour, so a few kilograms either way changes the result by only a handful of calories.

How jumping rope at a slow pace compares at 55 kg

Activity MET kcal per hour kcal per 30 minutes
Jumping rope at a slow pace 8.8 484 242
Running at 5 mph 8.3 457 228
Cycling, moderate effort 8.0 440 220
Rowing, vigorous effort 8.5 468 234
Running at 6 mph 9.8 539 270

The comparison is the honest way to choose between activities. A higher MET is not automatically better: an activity you enjoy and repeat three times a week beats a harder one you quit after a fortnight, and joint-friendly options matter more than raw burn for anyone with knees or a back that complain. Use the table to see the trade-offs — for example, swapping a lower-MET activity for a higher one for the same 30 minutes — and then choose on enjoyment and sustainability, not on the biggest number.

How to use the result

Start with one- to three-minute intervals with a minute of rest between them, and build the total time over weeks rather than trying to jump continuously for twenty minutes on day one. Jump on a forgiving surface — a wooden floor, a gym mat or grass — rather than concrete, wear supportive shoes, and keep the jumps low: an inch off the ground is enough, and higher jumps only tire the calves faster.

Size the rope properly: stand on its middle and the handles should reach your armpits. A rope that is too long catches on your feet; one that is too short forces you to hunch. Keep your elbows close to your body, turn the rope with your wrists rather than your whole arms, and land softly on the balls of your feet with knees slightly bent.

For weight loss, the activity calories sit on top of your daily food intake, and the safe frame is a deficit of roughly 300–500 kcal a day, aiming for 0.5–1% of body weight per week. Never let the activity numbers talk you into eating far less: the safety floors are 1,200 kcal a day for women and 1,500 kcal a day for men, and any intake below those needs medical supervision. A 484-kcal session does not "earn" an extra meal of the same size, either — the body compensates, appetite rises after hard sessions, and the deficit that matters is the weekly average, not a single day's maths.

What the number does NOT tell you

MET values are population averages, and the error on any single person is real. The Compendium value was measured on a sample of adults, not on you, and it assumes a standard intensity. If you push harder than the standard, you burn more; if you coast, you burn less. Heart-rate monitors and power meters estimate the same thing from different signals and disagree with each other by 10 to 20% on a good day, so treat every figure — including this page's — as accurate to roughly that band, not to the single calorie.

The figure also counts gross energy, which includes the calories you would have burned sitting still during that hour anyway. The extra burn above rest is the gross figure minus your resting rate for that hour (roughly 55 kcal for a 55 kg person at 1 MET), so the net cost of an hour of jumping rope at a slow pace is about 429 kcal, not 484. That distinction matters when you add activity calories to a daily total that already includes your resting metabolism — counting gross calories on top of a full BMR double-counts the resting hour.

The MET value assumes continuous jumping at a slow pace. Real sessions include rests, tangles and missed jumps, and every stop pulls the average down — a session of three-minute intervals with rests burns less per minute than the table suggests, even though it is the right way to train. Skill matters too: an experienced jumper is more efficient and burns slightly less for the same rope speed than a beginner who jumps higher and stiffer.

Finally, the formula knows nothing about your body composition, fitness, or health. Muscle burns more than fat at rest, trained people are more efficient at a familiar activity (and therefore burn slightly less for the same work), and illness, heat, altitude, and medication all shift the real number. If you have a medical condition, are pregnant, or take medication that affects heart rate or metabolism, treat this page as background information and talk to a clinician before building a training or weight-loss plan around it.

Frequently asked questions

How many calories do I burn jumping rope slowly for 30 minutes at 55 kg?

About 242 kcal if the jumping were continuous. In practice most people jump in intervals, so a realistic 30-minute session with rests comes to less — a useful rule is to count only the minutes you are actually jumping. Ten minutes of continuous slow jumping at 55 kg burns about 81 kcal.

Is slow jumping rope good for beginners?

Yes — it is the best way to start. The pace is forgiving, the jumps are low, and you can stop and restart whenever you need to. Start with one-minute intervals, focus on rhythm rather than speed, and build up over several weeks. If you have knee, ankle or foot problems, check with a clinician first, and jump on a soft surface.

How does slow jumping rope compare with running?

Slow jumping rope at 8.8 METs burns slightly more per minute than running at 5 mph (8.3 METs) and slightly less than running at 6 mph (9.8 METs). At 55 kg, an hour of slow rope is 484 kcal against 457 kcal for running at 5 mph. The practical difference is that rope work is done in one spot and is harder on the calves, while running is easier to sustain for longer.

Is jumping rope bad for your knees?

It can be, if done badly. High jumps on concrete with stiff legs are hard on the knees and ankles. Low jumps on a forgiving surface, with soft landings on the balls of the feet and slightly bent knees, are much kinder. People with existing knee problems should get advice from a clinician before starting, and should stop if a joint hurts sharply rather than just feeling tired.

How many calories does 10 minutes of slow jumping rope burn?

At 55 kg, about 81 kcal of continuous jumping. That is a lot for ten minutes, which is why rope work is so time-efficient — but it is also why most people cannot jump continuously for ten minutes when they start. Three sets of three minutes with rests between them is a realistic first target, and it still burns roughly 73 kcal of jumping time.
