Are we consuming too many calories? For Futura, nutritionist Arnaud Cocaul details the relevance of the calorie calculation system. Indeed, it can be counterproductive by focusing our attention on the wrong side of the problem.

The 17e stage of the Tour de France 2021 looks like an impossible challenge. From the 70e kilometer begins a slow ascent to Bagnères-de-Luchon, before a series of three passes at an altitude of more than 1,500 meters, with barely one or two kilometers of flat between each ascent, to finish with a finish of 16 kilometers at 8.7% slope. And no time to rest: the next day, the Col du Tourmalet and its 2.115 meters await the runners at 94e kilometer.

With these 21 stages and 23 days of racing, the Tour de France is definitely not a piece of fun. And not to falter in the middle of an ascent, it is better to have taken a Crystals and amorphous solids

For more than 20 years, John Eric Goff, researcher in sports physiology at the University of Lynchburg in the United States go through each stage of the Tour with a fine-tooth comb. By analyzing the relief and the speed having a direction and an intensity is represented by a vector, the speed vector. Relative speed is the speed of one body relative to another or relative to a benchmark. “Data-image =” https://cdn.futura-sciences.com/buildsv6/images/midioriginal/3/1/ 9 / 319daf63f4_77541_leibniz-dp.jpg “data-url =” https://www.futura-sciences.com/sciences/definitions/physique-vitesse-324/ “data-more =” Read the definition “>speed runners, he manages to predict the time of arrival with devilish precision. But above all he amused himself by calculating the number of calories spent by a runner over the entire 2020 race.

The power of a microwave in your legs

« A normal cyclist produces around 250 to 300 watts d’energy in 20 minutes », Explains the researcher. Tour professionals can go up to 400 watts, or even 1,000 watts during a steep climb. ” It’s about the power of a microwave “, Compares John Eric Goff on the site The Conversation. But all this energy is unfortunately not used to move the bike forward, due to the resistance of the’air and wheel friction. Taking these “losses” into account, the average cyclist must produce an effort of 325 watts continuously over the 80 hours of the race (remember that an average cyclist does not produce more than 300 watts over 20 minutes).

The Tour de France. Verdict: 120.649 calories, or about 5,745 calories per step. This corresponds to a total of around 220 Big Macs at 550 calories, or 431 pain au chocolat at 280 calories. ” For some stages, like the 17e of the 2021 route, energy expenditure can climb to 8,000 calories, adds the researcher. During the three weeks of the race, a runner will burn around 40 kilos of fat. »

Energy bars and fruit jellies

The problem is that runners are more of a weakling type, so as not to overload themselves with extra pounds. The winner of the Tour 2020, the Slovenian Tadej Pogačar, weighs only 66 kilos.
