At the edge of the pool, the athletes nervously and attentively make their final preparations. The sleek bodies shimmer in the pool lights, as if they were fish about to be thrown into the water, ready to swim in the ocean of competition.
However, there is one step in these preparations that is often unknown to outsiders – and that is the pre-race "shaving" ceremony. To the outside world, this may be an "unspeakable" secret for swimmers, but inside the swimming world, it is an open secret, a link that is both practical and essential.
Why do world-class swimmers not only need to hone their skills and improve their fitness through countless pool trips to and from major competitions, but also have to go through the unique preparation process of shaving before the competition?
Personal image and professionalism
In highly specialized sports such as swimming and diving, athletes' preparation goes far beyond training and physical conditioning.
On the eve of the competition, shaving their body hair became part of their routine, not only to reduce resistance in the water, but also to reflect their self-image, professionalism and seriousness towards the competition.
Among many sports, swimming and diving pay special attention to the appearance of athletes, which is closely related to the openness and spectacle of these sports.
The process of shaving body hair is simple, but it requires a high level of self-discipline on the part of the athlete. They usually choose to do this the night before or the morning of the day of the race.
This process includes not only leg and arm hair shaving, but also chest and armpit hair for male athletes. Female athletes are no exception, taking care of their body hair with more care to ensure they look their best when they compete.
In addition, after shaving body hair, athletes also use a variety of skin care products to reduce skin irritation and keep the skin smooth and healthy.
Not only do these products help them reduce the discomfort that can occur when shaving, but they also protect the skin from the chemicals in the pool water. This is especially important for athletes as they train and compete for long periods of time in the water, and the health of their skin is directly related to their performance and performance.
Athletes usually go through a series of preparations before shaving their body hair. They soak in warm water for a period of time to soften the hair, and then use a special shaving tool and shaving foam or gel to reduce skin damage.
The whole process is not only a maintenance of personal image, but also a preparation for the competition, reflecting the athlete's respect for their profession and the importance they attach to the competition.
In international competitions, athletes represent not only themselves, but also the entire country. Therefore, while keeping their personal image neat and generous, they are also showing the image of the country to the world.
This inside-out professionalism and sense of national pride make every athlete who appears on the stage become an ambassador for their country.
Scientific reduction of water resistance
In world-class swimming and diving competitions, body hair shaving is one of the ways in which every athlete is looking for ways to make themselves faster, taller and stronger.
Scientific studies have proven that shaving body hair can be effective in reducing an athlete's drag in the water, even if the reduction is very small, but in a top-level matchup, such details can often make the difference between victory and defeat.
Resistance is a central concept in fluid mechanics and affects the speed at which an object moves through a fluid. For swimmers, reduced drag means faster cutting of the current, resulting in higher swimming speeds.
As an athlete moves through the water, every inch of skin on the surface of the body rubs against the water, and this friction is one of the sources of resistance. Hair increases the roughness of the skin's surface, which increases friction with water. Therefore, shaving the body hair and smoothing the surface of the skin can reduce this resistance to some extent.
To achieve this, athletes take a variety of measures to ensure the smoothness of their skin. In addition to using a traditional razor to shave body hair, some athletes also use longer-term hair removal methods such as hair removal creams and laser hair removal to keep their skin smooth for a long time.
In addition, skin care after shaving body hair is equally important. Athletes use a variety of moisturizing and repairing skincare products to avoid razor scratches and dry skin, ensuring that the skin is kept in top condition.
This process is not just a physical operation, it also involves the scientific understanding and care of the athlete's skin. A professional sports medicine team will recommend the most suitable hair removal and skincare regimen based on the athlete's skin type. These protocols are designed to minimize skin damage while ensuring long-lasting and effective hair removal results.
Before the competition, the athletes undergo one last comprehensive hair removal treatment, which has almost become part of their pre-competition rituals.
Through this series of carefully prepared steps, the athletes are not only physically prepared to fight the water, but also mentally ready for the competition. They know that only by reducing resistance in all directions can they perform at their best in the race.
The athletes' outstanding performance in the competition is the result of countless training and preparations, and shaving body hair is just one part of it.
It's a small session, but it's a testament to the athletes' attention to detail and desire to win. At the edge of the pool, as they stood on the starting platform with fully dressed and smooth skin, every spectator could feel their preparation and sacrifice for victory.
The need to maintain water quality
In water sports such as swimming and diving, the athlete's interaction with the water is one of the key factors in competitive performance. Therefore, in addition to improving performance directly through technology and physical fitness, maintaining the water quality of the pool is also very important. This is not only about the health of the athletes, but also about the fairness and spectacle of the competition.
In this process, body hair is shaved not only to reduce personal resistance, but also to reduce the possible negative impact on water quality.
If the shedding hair is not removed in time, it will spread in the water, which not only ruins the beauty of the pool, but more importantly, they will be swept into the circulating filtration system.
Once these hairs clog the filtration system, it can affect the water circulation and purification process, resulting in poor water quality. The deterioration of water quality will not only affect the physical health of the athletes, but also the quality of the competition, as the unclear water will reduce the visibility of the underwater action, affecting the judgment of the referee and the viewing experience of the spectators.
Furthermore, the oil and other tiny particulate matter in the hair in the water can become a medium for bacteria and microorganisms that, once multiplied, can greatly increase the risk of mutual infection among athletes.
Especially during intense competitions and high-intensity training, an athlete's immune system may be affected, and they are more susceptible to infections. Therefore, reducing hair loss by shaving body hair is a very important preventive measure to protect the health of athletes and ensure the smooth running of the competition.
The auxiliary role of the swimming cap
In sports such as swimming and diving, which require extreme speed and precision, athletes not only improve their competition through daily training, but also reduce resistance in the water in various ways.
Among them, the use of swimming caps is an effective method. Swimming caps can not only compress the hair, reduce water resistance, but also prevent hair loss to a certain extent, which plays a key role in maintaining the cleanliness of the pool water quality.
The design of the swimming cap takes into account the principles of fluid mechanics, allowing it to fit snugly into the shape of the athlete's head, thereby reducing the drag created by the flow of water on the head. This design is suitable not only for athletes with long hair, but also for athletes with short hair, as it is able to wrap all the hair tightly, reducing the turbulence of water between the hairs, thus reducing resistance.
In addition, the high-quality swimming cap material is also elastic, which ensures that athletes with different head shapes can find the right size, and the hat is neither too tight and uncomfortable, nor too loose and falling off in the water.
Although a swimming cap is able to reduce water resistance and prevent hair loss to a great extent, it is not a complete substitute for shaving body hair. Shaving body hair is a more fundamental method that directly reduces the friction of the water when it comes into contact with the body by removing the hair from the surface of the body.
This method is particularly useful for top athletes who are extremely sensitive to performance, as even the slightest difference in drag can affect the final outcome of a race at a high level.
To minimize water resistance, athletes often resort to a combination of methods, including but not limited to shaving body hair, wearing a swimming cap, and using specially designed competition uniforms.
Together, these measures help athletes reach higher speeds in the water. In practice, athletes carefully check that the cap is worn correctly to ensure that it covers the entire head tightly and that the rest of the body is prepared accordingly.
International norms and health and safety
The International Swimming Federation (FINA), the highest governing body for global swimming competitions, has formulated a series of regulations designed to protect athletes' health, ensure the fairness of competitions and ensure the safety of water quality.
These regulations are extremely strict on the water quality of the competition, covering many aspects such as the chemical composition, physical properties and hygienic status of the water. Specifically, water quality monitoring includes key indicators such as the pH of the water, the chlorine content, and the total number of bacteria, which are directly related to the health of athletes and the fairness of the competition.
In order to meet these international norms, swimming venues must invest a lot of manpower and material resources to maintain water quality. First of all, a professional water quality management team will conduct a comprehensive test of the pool water on a regular basis using advanced testing equipment to ensure that all indicators meet the strict standards of FINA.
This includes not only regular daily inspections, but also special pre-race testing to ensure the stability of water quality during the competition.
In addition to relying on modern technical equipment, swimming pools need to take a variety of measures to maintain water quality.
For example, the use of automated chemical delivery systems to adjust the pH and chlorine content of the water, the use of high-efficiency filtration systems to remove bacteria and particulates from the water, and the regular replacement of pool water to ensure that the water is fresh and clean.
Athletes' personal hygiene habits also play a crucial role in this set of measures. By shaving body hair, athletes can not only reduce drag in the water and improve their performance, but more importantly, effectively prevent hair from falling out and entering the water, reducing water pollution.
This seemingly simple personal hygiene habit is actually a positive response to international competition norms, reflecting the importance that athletes attach to the fairness of the competition and public health and safety.
In addition, shaving body hair also helps to reduce the attachment of bacteria and microorganisms to the skin, which reduces the risk of bacteria entering the water. This is especially important for public pools that are used in groups, as it can effectively reduce the possibility of cross-contamination and protect the health and safety of all those who use the pool.
These individual athletes' practices, combined with professional water quality management at swimming venues, form a comprehensive water quality protection mechanism. This not only ensures that athletes can train and compete in a healthy and safe environment, but also ensures that spectators can enjoy high-quality, fair and just competitions.
