Effectiveness of high-intensity interval training in increasing endurance in singles tennis

Abstract

The purpose of this article is to evaluate the effectiveness of high-intensity interval training in developing endurance and maintaining the playing capacity of tennis players, as well as to develop scientifically grounded recommendations for its application in the training process. Methods. The study used a systematic analysis to investigate the physiological mechanisms of high-intensity interval training on the bodies of athletes and to evaluate its effectiveness based on available experimental data. Methods of generalization and comparative analysis were applied to identify the most effective high-intensity interval training protocols, as well as to compare the results of using different approaches (HIIT, RST, IIT) in the training of tennis players and athletes in related sports. The synthesis method was employed to formulate practical recommendations for integrating high-intensity interval training. Results. It was determined that high-intensity interval training is a universal and effective tool for developing both aerobic and anaerobic endurance. The analysis of studies has shown that high-intensity interval training significantly increases VO₂peak and general endurance. Combining it with other methods, such as RST and IIT, allows for targeted improvement of qualities specific to tennis, including recovery speed and repeated sprint ability. It was concluded that the effectiveness of training depends on an integrated approach that considers the athlete's age, skill level, and individual characteristics. Conclusions. It is emphasized in the conclusions that high-intensity interval training is a fundamental component of modern physical training in tennis. Its value lies not only in its physiological impact but also in its ability to simulate game loads, which allows for an optimal combination of developing physical qualities with maintaining technical and tactical mastery. It makes it a key tool for coaches who seek to use training time as effectively as possible, as well as a holistic strategy for achieving the highest athletic results.
