Abstract

Swimming activities, particularly the 400-meter freestyle competition, have become a fertile area for research in the field of sports training physiology due to the event's demand for endurance-speed as a key performance quality. The importance of this research lies in developing a scientifically grounded training program that incorporates key physiological indicators—such as heart rate and blood oxygen saturation—to enhance vital capacity, physical efficiency, and turnaround time in the 400-meter freestyle. The research problem stems from the limited use of training methods that consider functional variables, especially those that help assess the physical strain experienced by athletes during training, which is essential for regulating training loads and preventing injury. The objective of the study is to create a training program aimed at improving performance in the 400-meter freestyle through monitoring oxygen deficiency and heart rate. The findings concluded that the applied approach effectively improved athletes’ endurance-speed tolerance and overall performance in the 400-meter freestyle. The researchers recommend using supportive medical devices, such as Alaxometer, to help accurately determine training intensity for athletes.
