Nutrition and doping issues are rarely studied in the sport of tennis. The aims of this investigation were to determine knowledge on doping (KD) and knowledge on sport nutrition (KSN), and corresponding socio-demographic-, sport-, and sport-nutrition- and doping-factors among an international sample of high-level tennis players of both sexes (43 females; 22 years old on average). In the first phase of the investigation, the KSN and KD questionnaires were studied for their reliability and validity. The consumption of NS is found to be very high, with almost of all the females and 80% of the males using NS at least occasionally. The athletes showed a low tendency regarding future doping usage, although most of them are convinced that doping does exist in tennis. Since athletes declared that their coaches are their main source of information about NS and doping, future studies should investigate what coaches actually know about such problems. KSN has been found to be protective against potential doping behavior in the future. Males are found to be more prone to doping than females. Therefore, in order to prevent doping behavior in tennis we strongly suggest intensive educational programs on sports nutrition and doping-related problems. Key PointsThe incidence of nutritional supplementation use among the tennis players is found to be very high, especially among the females.Although most of the subjects are of the opinion that the doping behavior is present in tennis circuit, we have found a low tendency regarding future doping usage, and high levels of athletes' trust in their coaches with regard to nutritional supplementation and doping.There are indices that the knowledge about nutrition is protective factor against potential doping behavior. It clearly reinforces the need to include a wide educational program on sports nutrition in tennis, but also in other sports.
营养与兴奋剂问题在网球运动中很少被研究。本研究旨在确定国际高水平男女网球运动员（43 名女性；平均年龄 22 岁）对兴奋剂（KD）和运动营养（KSN）的知识，以及相应的社会人口统计学、运动学、运动营养和兴奋剂因素。在研究的第一阶段，对 KSN 和 KD 问卷进行了可靠性和有效性研究。发现 NS 的消耗量非常高，几乎所有女性和 80%的男性都至少偶尔使用 NS。运动员对未来使用兴奋剂的倾向较低，尽管他们大多数人都相信兴奋剂确实存在于网球运动中。由于运动员表示他们的教练是他们获取关于 NS 和兴奋剂信息的主要来源，因此未来的研究应该调查教练对这些问题的实际了解情况。KSN 被发现对未来潜在的兴奋剂行为具有保护作用。男性比女性更容易出现兴奋剂行为。因此，为了防止网球中的兴奋剂行为，我们强烈建议对运动营养和与兴奋剂相关的问题进行强化教育计划。
网球运动员使用营养补充剂的发生率非常高，尤其是女性。
尽管大多数研究对象认为兴奋剂行为存在于网球巡回赛中，但我们发现未来使用兴奋剂的倾向较低，运动员对教练在营养补充和兴奋剂方面的信任度很高。
有迹象表明，营养知识是对潜在兴奋剂行为的保护因素。这清楚地强调了在网球运动中以及其他运动中纳入广泛的运动营养教育计划的必要性。
