DISCONTINUOUS TRAINING METHODS AND THEIR INFLUENCE ON LACTIC AND CARDIAC BEHAVIOR IN HIGH PERFORMANCE 400M RUNNERS

Abstract

Introduction: High-intensity interval training is widely used to improve anaerobic and cardiovascular capacity in prolonged speed events, thereby increasing lactate tolerance and improving buffer and oxidation capacity, which delays muscle fatigue during maximum efforts.Objective: The aim of this study was to determine how discontinuous training methods influence the lactate and cardiac components of 400m runners from the Ecuadorian national Paralympic team.Methodology: A pre-experimental study was conducted on a sample of seven high-performance athletes.Results: After applying for the t-Student test, a significance of < 0.05 was observed.Discussion: This demonstrates a positive impact on cardiac recovery and strengthening of the cardiovascular system, as well as significant lactate clearance due to appropriate adaptation to training. Conclusions: These findings confirm that discontinuous methods are effective for designing specific training programs for 400m athletes, especially in the special stage.
