The race, however, is a sport that is practiced even in difficult weather conditions or extreme running, for example, with high temperatures in the desert, it runs in the ice of the North Pole or the South Pole. According to Prof. Fulvio Massini, professor of Athletics at the Faculty of Medicine, University of Florence, you can run with the cold but on certain conditions. "It starts, first, by analyzing the physiological responses of the body to cold" - says Prof. Massini in the pages of benessere.com - adding that "the low outside temperature does get less blood to the skin surface to hold it all 'internal body. Also they can be felt shivers: synchronous and involuntary muscle contractions, which are designed to increase the body heat. In a cold environment, also, it may appear the phenomenon of "goose bumps" or "horripilation" which consists in the erection of the skin and hair, to limit the exchange surface between body and outer calorie ".
"Having said this" - continues Prof. Massini - "you need to give advice so that you can know how to train in cold conditions: first of all we see those who tolerate the cold better. A thin layer of subcutaneous fat allows you to better withstand low temperatures. Runners generally tend, rightly, to be leaner possible. Who will take part in a competition on the ice it will be good that is present in slight overweight. Too much fat would create other problems, in relation to stroke, a very small layer of fat will protect the internal organs. Women, scientists say, tolerate the cold just like men, so the cold is not, for them, a contraindication to run. "
Another very important thing is clothing: one of the greatest dangers can be made to be held on clothing wet with sweat. The head must be covered by a warm hat to take off when no longer needed if n'avverta. Ears: captain also Italy in those days when it seems hard that your ears may become broken; hat must therefore also cover the ears, or you can wear a hat and a para-ears. The trunk must be covered by a short-sleeved shirt, thermal, and a sweater or long-sleeved shirt pretty heavy, always heat. If it gets really cold and the wind blows a lot, it can be worn over a jacket always material with the characteristics described above. With the passage of kilometers, if not windy, the jacket can be removed and tied at the waist.
The legs will be covered by a long tights, always in thermal material. The feet are instead covered with a nice pair of socks rather thick. They are preferred long socks to keep covered the calves. Before moving socks is recommended to prepare the foot with the balm to ensure a good blood circulation. The hands should be covered with light gloves to take off in the event of excessive heat. Situation that will be difficult if you'll run the poles north or south. Who runs faster will cover less, especially in the race. During the latter, a thermal shirt with short sleeves with a long-sleeved top and a pair of shorts will be more than enough. Socks must then necessarily cover the calf. Undershirt social will be the last garment to wear and will aim more decorative than protective. Those who runs at slower pace, in the race, will be covered as indicated earlier. Who suffering intestinal or digestive problems, can be worn over the tights a pair of shorts or even, in the case "extreme" a belt of the type "Gibaud". On the snow you can run well with normal running shoes equipped with tread accentuated. Excellent for this purpose shoes Trial.
"Thinking about how they train at night and then stop to stretch before you get in the car" - said Prof. Massini - "to them it must be said not to be taking the cold in vain, but to go, as soon as possible, in a dry, get changed and after stretching. When it is cold you should not run workouts with acceleration and deceleration. "
