Avaliação do consumo hídrico e do conhecimento sobre hidratação em jogadores de Beach Tennis

Abstract

This study investigates the importance of hydration for the health and performance of athletes, with an emphasis on Beach Tennis players, highlighting the role of water in nutrient transport and thermal regulation. Dehydration is presented as a factor that impairs physiological functions, especially in hot climates, where there is greater loss of body fluids. In Beach Tennis, a sport played on sand courts under high sun exposure, adequate water configuration is essential to prevent symptoms such as dizziness, cramps and loss of performance. This situation justifies the need to educate athletes on more effective hydration practices, including the use of isotonic drinks that, in addition to providing fluids, provide essential electrolytes for thermoregulation and adequate muscle function. The objective of the study was to evaluate water consumption and the level of knowledge about hydration among Beach Tennis players at an arena in João Pessoa - PB, according to the guidelines recommended by the American College of Sports Medicine. The sample consisted of 20 amateur players of both sexes and aged between 20 and 51 years old, and was obtained from questionnaires on water intake before, during and after training. An analysis showed that, although 80% of the participants consumed the recommended amount of liquids before training, 30% still had a lower than ideal intake during sports practice. The lack of formal guidance on hydration, reported by 65% of the players, reflects a lack of awareness about the need for continuous water regulation, especially in outdoor activities and in hot environments. In addition, it was found that 45% of the participants confirmed the importance of drinking liquids before feeling thirsty, although many still opt for conventional drinks, such as soft drinks and alcohol, which can aggravate dehydration. The study proposes that continuous education practices on adequate water intake, combined with regular monitoring of water loss, are essential to optimize sports performance and preserve the health of Beach Tennis players. This study suggests that implementing preventive strategies, such as formal guidance on hydration, can improve athletes' awareness and water habits, promoting safer and healthier sports practice.
