International Tennis Federation (ITF), Women's Tennis Association (WTA), and Association of Tennis Professionals (ATP) Expert Group Statement on Nutrition in High-Performance Tennis. Current Evidence to Inform Practical Recommendations and Guide Future Research. International Journal of Sport Nutrition and Exercise Metabolism 2025 Aug 21:1-38. doi: 10.1123/ijsnem.2025-0001.1526-484X (print)1543-2742 (online)10.1123/ijsnem.2025-0001http://hdl.handle.net/2263/104455The sport of tennis involves unique nutritional demands for the physical and technical aspects of match play and training, as well as the nutritional challenges associated with extensive travel and a lengthy competition calendar. An expert group assembled by The International Tennis Federation, the Women's Tennis Association, and the Association of Tennis Professionals has produced a scientific review of current evidence to inform practical recommendations for high-performance tennis. The narrative summary considers the diversity within the tennis community, including male and female players, youth players, and wheelchair players. The Expert Group Statement addresses nine specific topics: (a) introduction to tennis; (b) physiological characteristics of tennis training and match play; (c) training nutrition; (d) body composition, low energy availability, and relative energy deficiency in sport; (e) match-day nutrition; (f) dietary supplements for tennis performance; (g) environmental and travel issues; (h) nutrition guidelines during periods of illness and injury rehabilitation; and (i) special population groups. The statement advocates for an evidence-based approach to nutrition in high-performance tennis and emphasizes a "food first" philosophy, prioritizing food over supplements to meet nutrient requirements effectively. In recognition of the benefits of sound nutrition, strategies in supporting health and performance over a player's career, academies, national federations, and international organizations are encouraged to engage professionals with appropriate nutrition-related qualifications and professional registrations to support players effectively.en© 2025 Human Kinetics, Inc.Dietary guidelinesFood firstHydrationPerformanceRacket sportsArticle
