What is the competition standard in nordic combined?

In ski jumping, in order to increase the jumping distance, we should choose a long ski, the length is generally × 1.46, and there are three grooves at the bottom of the ski. The maximum width of the snowboard is 1 1.5 cm. According to the athlete's height and weight. Ski poles are not allowed for ski jumping.

Cross-country competition techniques can be freely adopted, including freestyle or traditional techniques, and there are also such differences in snowboarding. The difference between traditional plate and free plate mainly lies in structure and length:

Free disk: The bottom of the free disk is smooth and generally coated with wax. The smooth plane makes the resistance of athletes less. For freestyle cross-country snowboarding, the length of the snowboard should be extended from 10 to 15 cm according to your height, but at the same time, the hardness (tension) of the snowboard should be considered to adapt to your weight. The right ideal weight is usually marked on the snowboard.

Traditional board: the traditional board has a certain tension, and the whole board body includes climbing board and skateboard. The length of the snowboard is the height plus 30 cm. Similarly, the tension of the snowboard should be commensurate with the weight. This can be measured by standing on a snowboard and measuring the gap between the bottom of the snowboard and the ground. Measure the distance between the heel and every two marks on the snowboard. A piece of paper can be added to the crack, and the tension of the whole plate is up to standard.

Freestyle ski shoes: the upper should be higher than the ankle, forming a certain support. At the same time, make sure that your ankles can move freely and that you can stand on the snowboard in the best posture at any time.

Traditional ski shoes: Ski with traditional shoes with lower uppers. Footsteps are supportive, and ankles can move greatly, which is conducive to the display of skiing movements. Multifunctional ski shoes: Due to the limitation of the project, you can also choose multifunctional shoes, which are suitable for both freestyle and traditional technical requirements.

The choice of ski poles is varied, so it is necessary to choose the appropriate length for specific competitions according to local conditions. Ski clothes should ensure that the body can move freely, not too tight. Ski clothes are elastic, windproof and moisture-proof, easy to maintain and washable. Ski gloves should feel tight when worn.
