Tart cherry (TC) supplementation can improve exercise recovery and performance; and may also improve sleep duration and quality. This study investigated the use and knowledge of TC supplementation by athletes of all competitive levels. Eighty participants (52.5% elite (international, national, professional), 47.5% sub-elite (semi-professional, state/regional, county level, club level, recreational)) completed an online questionnaire investigating their attitudes towards and use of TC supplementation. Overall, 22.6% of participants were using or had previously used TC supplements, and 12.5% of participants planned to used TC supplements. Improved recovery (71.4%), sleep (32.1%) and immunity and general health (32.1%) were the most frequently indicated goals by respondents using TC supplements. In total, 32.1% of respondents were supplemented with TC chronically, 39.3% acutely and 28.6% used a combination of chronic and acute supplementation. The majority of those employing TC supplementation chronically used TC either over 2–3 days (37.0%) or continuously (37.0%). The most popular TC pre- and post-loading period was one day (34.3% and 41.5%, respectively). There were no significant differences between elite and sub-elite athletes in any parameters assessed (p > 0.05). TC supplementation is not widely used by the athletes surveyed, and athletes using TC supplements showed poor awareness of an evidence-led dosing strategy, regardless of competitive level.

精英运动员和亚精英运动员对T樱桃补充剂的使用，做法和态度

酸樱桃（TC）补充剂可以改善运动恢复和性能；并且还可以改善睡眠时间和质量。这项研究调查了各个竞技水平的运动员对TC补充的使用和知识。80名参与者（52.5％的精英（国际，国家，专业），47.5％的次要精英（半职业，州/地区，县级，俱乐部级，娱乐性））完成了在线调查问卷，调查了他们对TC补充的态度和使用情况。总体而言，有22.6％的参与者正在使用或曾经使用过TC补充剂，而12.5％的参与者计划使用过TC补充剂。使用TC补充剂的受访者最常指出的目标是，改善康复（71.4％），睡眠（32.1％）和免疫力以及整体健康（32.1％）。总共32个。1％的被调查者长期补充了TC，39.3％的被紧急补充了，而28.6％的人则联合使用了慢性和急性补充。大多数使用TC补充剂的人长期使用TC的时间为2-3天（37.0％）或连续使用（37.0％）。最受欢迎的TC加载前和加载后时间是一天（分别为34.3％和41.5％）。在评估的任何参数上，精英运动员和亚精英运动员之间没有显着差异（p > 0.05）。被调查的运动员并未广泛使用TC补充剂，使用TC补充剂的运动员对循证剂量策略的认识不足，无论其竞技水平如何。
