How is cross-country skiing developing?

19 In the 1950s, when the traditional skiing style of two poles was really established, with the rapid progress of top athletes, the development speed of this sport exceeded any other endurance training (such as running or swimming). Snowboarding is more technical, and athletes begin to learn physiology and how to train their bodies to prepare for the competition. However, skating skills have also developed almost simultaneously.

In the 65438+60' s, machines for laying slideways (or ski slopes) appeared. Previously, the army (that is, hundreds of soldiers using skis) was responsible for compacting and preparing the track for the competition. Because skiing has only two prepared slots, skiers can only keep their legs parallel and take turns pedaling, and nothing else can be done. At this time, however, Finnish policeman Pauli Si Tong began to do experiments, leaving only one leg in the groove and the other leg for pushing things. Of course, one leg will soon get tired and have to be replaced. This method is called "Si Tong step" or "semi-skating". When skiers (especially those who have been trained in long-distance running and have good leg strength) begin to test these new technologies on the slide after using the new machine to compact it, they find that the two legs can advance faster by taking turns, which can reach 10%, which leads to skating and skiing.

1924, cross-country skiing was listed as the first Winter Olympics. Men have 10km (including 1992), 15km (including 1924), 30km (including 1956) and 50km (including 1924). Women's 5km (including 1964),10km (including 1952),15km (including 1984) and 30km (including 1992).
