Optimizing the Performance of Junior Middle-Distance Swimmers: Interactions Between Metabolic Conditioning, Respiratory Training, and Sports Recovery

The rapid evolution of international performances and methodological transformations in sports science require reconsidering traditional training models, predominantly oriented towards the development of aerobic capacity, adapted to the current requirements of the competition. This paper analyzes the theoretical and applicative foundations of an innovative methodological model, intended for junior swimmers specializing in 200 and 400 m events, based on the harmonization of mixed metabolic training, with respiratory muscle training and modern sports recovery strategies. The analysis of the specialized literature highlights the determining role of VO₂max, anaerobic threshold, lactate tolerance, ventilatory efficiency and post-exertional recovery, in optimizing sports performance. The absence of unitary experimental models that integrate these components into a coherent training strategy for junior middle-distance swimmers is identified. Therefore, this paper proposes an interdisciplinary perspective on contemporary swimming training, which is oriented towards the development of superior metabolic adaptations, increasing functional efficiency and the sports recovery process.
