Sand doesn’t stick to volleyball players primarily due to the specific regulations and characteristics of the sand used in the sport.
The sand used in volleyball courts, especially in beach volleyball, is carefully selected and regulated to ensure player safety and optimal gameplay.
Here are some key factors contributing to why sand doesn’t stick to volleyball players:
Первый, the sand used in beach volleyball is specifically designed to not stick. It is sieved to a certain size, which prevents it from being too coarse or too fine. Coarse sand would scrape the players’ skin, while fine sand would create dust that would stick to their skin. The ideal sand size for beach volleyball is 0.5mm to 2mm.
Второй, the sand used in beach volleyball is also designed to have excellent drainage. This means that the water content of the sand is kept to a minimum. When water is present, sand grains tend to stick to each other and to our skin via tiny liquid bridges held together by surface tension. Однако, if the sand is dry, the sand grains will not stick to each other or to our skin.
Третий, volleyball players often take precautions to minimize sand sticking. They may apply sunscreen or moisturizers to create a barrier between their skin and the sand. Beach volleyball players often use a special towel to wipe themselves down during changeovers. This helps to remove any sand that has stuck to their skin.
Окончательно, the speed and agility of beach volleyball players also help to prevent sand from sticking to them. When players dive, they do so quickly and with a lot of force. This helps to knock the sand grains off their skin before they have a chance to stick.
As a result of all of these factors, sand doesn’t stick to beach volleyball players very much. This allows them to play the game without having to worry about sand getting in their eyes, mouth, or ears. It also helps to keep their skin clean and free of abrasions.
The science behind why sand doesn’t stick to volleyball players
The reasons why sand doesn’t stick to volleyball players can be attributed to a combination of factors, including the composition and size of the sand particles, the leveling and uniformity of the playing surface, the dryness of the sand, and the preparations made by the players themselves:
Sand Composition and Particle Size
The sand used in beach volleyball is specifically designed to not stick. It is sieved to a certain size, which prevents it from being too coarse or too fine.
Coarse sand would scrape the players’ skin, while fine sand would create dust that would stick to their skin. The ideal sand size for beach volleyball is 0.5mm to 2mm.
Leveling and Uniformity
The International Volleyball Federation (ФИВБ) sets guidelines to maintain the sand’s leveling and uniformity. This ensures a consistent playing surface and eliminates potential hazards that could cause injuries.
By keeping the sand free from rocks, ракушки, or other irregularities, the chances of sand sticking to the players are significantly reduced.
Dryness of the Sand
Volleyball players typically compete on dry sand courts, which have a lower moisture content compared to wet sand found on beaches. Dry sand particles are less likely to cling to the skin or clothing of players, as the absence of moisture inhibits the adhesion process.
Player Preparations and Equipment
Volleyball players take additional measures to minimize sand sticking. Applying sunscreen or moisturizers before the game creates a protective barrier between the skin and the sand, making it easier for any sand particles to slide off.
Some players also use specialized towels to brush off any sand that may accumulate during the game, ensuring they maintain a sand-free playing experience.
