Spectators who love swimming competitions will find a problem, whether it is summer or winter, swimmers come out in thick down jackets, which seems to be out of place with their surroundings and the sport. This made everyone around me feel very strange. So, why do swimmers wear down jackets?
In response to this problem, we can first understand the characteristics and functions of down jackets. Down jackets are generally made of duck down or goose down as filling, which is light in weight and soft in texture, and can fix more air than other clothing materials, and has good cold and warm performance.
Returning to the sport of swimming, it is a full-body sport in which all the muscles of the body need to be involved. Before the start of the competition, athletes need to do enough warm-up exercises to prevent muscle strains and improve flexibility. It is important to note that warm-up exercises do not fully acclimatize the athlete's body to the water temperature. There is always a certain gap between the temperature of the water and the body temperature, and it is easy to feel uncomfortable when entering the water. At the same time, at lower water temperatures, the core temperature of the human body drops, and the flexibility and strength of the muscles are affected. At this time, the role of the down jacket can be reflected.
Wearing a down jacket can help athletes effectively maintain their body temperature and avoid muscle stiffness caused by low water temperature, which can affect the normal performance of the game. At the same time, down jackets play an important role in reducing heat loss for athletes, helping them to better adapt to low temperatures. In addition, the lightweight down jacket does not burden the athlete with weight, and it is very soft and comfortable to wear, which will not affect the athlete's movement at all.
In addition to warmth, down jackets also have excellent moisture absorption properties, which can help athletes keep their bodies dry and reduce physical discomfort caused by sweat soaking, so as to maintain optimal competitive condition.
In short, athletes wear down jackets when they play in order to better adapt to the competition environment, maintain the temperature of their bodies, and participate in the competition in good competitive condition. This practice has become a routine operation in swimming competitions and has been widely used and recognized. With the continuous progress of science and technology, it is believed that more excellent equipment and technologies will emerge in the future to provide better support and protection for athletes.
