For example, how does calorie burn change as a function of slope? This equation gives you a value in watts, but that’s easy to convert to other units like calories per hour. That means that over a six-hour hiking day, he’d be burning 3,330 calories. Less active (rest day) Body weight (lbs.) M = 1.5 W + 2.0 (W + L)(L/W)2 + n(W + L)(1.5V2 + 0.35VG) You can vary the proportion of each by varying your speed and the amount of weight you carry.

Our rigorous coverage helps spark important debates about wellness and travel and adventure, and it provides readers an accessible gateway to new outdoor passions. Steps to calories calculator. A 120 pound (54.5kg) person will burn 2,091 in the same scenario. Essentially what this means is that total calorie burn while walking depends on both the distance that you walked and the speed at which you were walking. Doing the math shows us that rucking burns just under 2.5 times more calories than walking.

Calories burned backpacking with a 10lb load (per minute) = (7.3 x 81.65 x 3.5) ÷ 200 = 10.43Calories burned backpacking with a 10lb load (for 60 minutes) = 10.43 x 60 = 626. Imagine a whole spectrum of ways that humans can move while carrying weights. The idea of walking 10,000 steps per day - just under 5 miles for someone with an average stride length of 2.2-2.5 feet - has become a popular fitness goal around the world. Find more newsletters on our. For example, a 155-pound person burns approximately 232 calories walking at a moderate (3.5 mph) pace on a … My new book, Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance, with a foreword by Malcolm Gladwell, is now available.

For a person at 120lb, walking for a mile can help them burn up to 65 calories. The Hiking Calculator. Or a particularly light one? how to burn calories by walking with a weighted backpack.

You will, also, build muscle quicker which in turn will increase your metabolism which in turn will burn more calories. How much will you slow down on a prolonged climb or in sandy terrain if you maintain a roughly constant effort level? Sand is a little more complicated: its terrain factor is (1.5 + 1.3/V^2), meaning that it changes with hiking speed, so that the slower you go, the harder it gets. The sweet spot between walking too fast and supporting the pack for too long, in this sample case, is between 2 and 3 mph. However, the number of calories you burn will be dependent on your weight and how fast you are walking too so we can’t rely on time spent as the key. If you’re clipping along at 4 mph on a gravel path, then come to a section of ice (terrain factor 1.7), you’ll slow down by about 15 percent to 3.4 mph if you maintain the same energy output. You can find an activity’s MET on the chart above. Retrieved May 11, 2015, from the World Wide Web. At a 5-percent grade, you’d have to slow down to 2.9 mph.

But while walking uphill, your pack weight and your speed also contribute to the calories burned. Aerobics: Aerobics will burn calories more due to the intensity. A 200-pound (90.8kg) person will climbing hills with a 10-20lb load for 1 hour will burn 697 calories. A paved road has a terrain factor of 1.0; swamp has a terrain factor of 3.5. Here’s the calories-per-mile data for various terrains at three different speeds between 2 and 4 mph: You can see that bad terrain takes a disproportionately big toll at faster speeds. A task with a MET of 1 is roughly equal to a person’s energy expenditure from sitting still at room temperature not actively digesting food. Benefits of Walking with Weights A 200-pound (90.8kg) person climbing hills for an hour will burn 601 calories with no load, 620 calories with a 0-9lb load, 697 calories with a 10-20lb load, 792 calories with a 21-42lb load, and 859 calories with a 42lb+ load.

On one end is a super-heavy yoke carry or farmer’s walk: a trained weightlifter ca… Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance, our entire suite of free newsletters here, n: a “terrain factor” that adjusts the results for different surfaces (for example, a paved road has a terrain factor of 1.0, but a gravel road is 1.2, since it takes more calories to walk on a soft or uneven surface).
