The main reasons why the Chinese swimming team wears down jackets are as follows:
Maintain body temperature: Before swimming competitions, athletes need to warm up well to get their bodies in tip-top shape. However, athletes usually have to wait in the swimming pool for a while from the time the warm-up is completed until the competition officially begins. The ambient temperature around the pool is usually much cooler than the water in the pool, and wearing a down jacket can effectively prevent the athlete's body temperature from dissipating heat too quickly to maintain the muscle temperature during the warm-up.
Reduce muscle viscosity: Wearing a down jacket to maintain muscle temperature during warm-up can reduce muscle viscosity. Muscle viscosity refers to the resistance caused by friction between muscle fibers, muscles, or muscle groups when muscles contract or are elongated. Reducing muscle viscosity is beneficial for improving athlete performance in competition.
Improved performance: Wearing a down jacket to maintain body temperature and reduce muscle stickiness can make athletes perform better in competition. When the body is kept within a suitable temperature range, the athlete's muscles are able to contract and relax more flexibly, increasing the speed and efficiency of swimming.
Lightweight and comfortable: The down jacket is light and soft, and it will not affect other warm-up exercises after wearing. Compared to other heavy coats, down jackets are lighter and more comfortable, making it easier for athletes to carry out various preparation activities.
Team image: As the representative of the Chinese swimming team, the athletes' attire in the competition also represents the image and honor of the country. Wearing a uniform down jacket can enhance the cohesion and image of the team, and show the unity and self-confidence of the Chinese swimming team.
Psychological effect of warmth: In addition to the physiological warmth effect, wearing a down jacket can also bring a psychological comfort and encouragement to athletes. When facing a tense competition, a familiar down jacket may make an athlete feel more at ease and confident.
To sum up, the main reasons why the Chinese swimming team wears down jackets are to maintain body temperature, reduce muscle viscosity, improve competition performance, be light and comfortable, enhance team image and keep warm psychological effects. Together, these reasons support athletes to perform at their best in competition.
