Is crutches a must for cross-country races?

How do you see if you need to bring a stick in cross-country race?

1. Look at the altitude map of the track, the difference between the lowest and highest is more than 600 meters;

2. The climbing interval between two CP points exceeds 600 meters;

The tip of cross-country walking stick is generally made of high-strength tungsten steel alloy, which has strong puncture ability. For safety reasons, the following details should be paid attention to in daily use.

When you consciously feel that the walking stick will interfere with other athletes, please put away your walking stick, especially in places where there are many people at the start and start.

When running, you can hold your hand in the middle of the crutch when not in use. Of course, out of courtesy, the tip of the cane faces forward so as not to affect the runners behind.

When the tip of the stick falls, avoid the gap. There will be gaps in the terrain, such as paths, rock slopes, bridges, etc. Otherwise, the stick is easy to break and get hurt.

Don't pull people with a stick. Off-road terrain is more complicated. If you pull someone with a stick, the person who is pulled will not use too much force, which will easily lead to the danger of missing.

In addition, because the tip of most crutches is tungsten-cobalt alloy, which can break tempered glass, the Civil Aviation Administration stipulates that they cannot be carried with them and can only be hauled.

Labor-saving In the cross-country process, all the strength originally comes from the legs. If both hands can also generate forward force through the cross-country walking stick, the pressure on the legs and knees can be effectively shared, and the correct use of the cross-country walking stick can effectively save about 22% of energy consumption.

In the process of balancing cross-country running, some sections are too rugged to grasp the balance. Cross-country crutches can provide an additional 1-2 fulcrums to help coordinate the body to maintain balance.

At present, most crutches for cross-country running on the market are mainly folding sticks in order to reduce weight and facilitate storage. Unlike traditional crutches used in mountaineering, it is a tedious thing to adjust crutches in cross-country running that emphasizes speed. We need to choose the length of the cane from the beginning, such as walking. Stability and support are the main factors in climbing, and auxiliary climbing is the main factor in cross-country running.

When standing on the flat ground, the user's arm naturally droops, and then he can lift his arm to form an included angle of 90. At this point, the tip of the stick just touches the ground, so it can exert force, which is the best length of the stick.

According to the formula summarized by market science, the height of walking stick 1 is -55cm. For example, the height of 177 can be selected from 120cm and 125cm. Because the most important function of cross-country is uphill, it is suggested to choose the length of 120cm.
