Vol. 25, no. 2 (2024), pp. 81-89.The main objective of the research was to determine the impact of different forms of hypoxia (acute and intermittent) on the performance of performance swimmers. We realised pre and post-tests in 50-meter freestyle swimming speed (T1), counted the number of breaths taken during 50-meter freestyle swimming (T2), and measured the maximum underwater distance covered in one breath (T3). The study was conducted on a sample of n = 12 performance swimmers (4 females and 8 males), with the average age of 15.75 years, average body weight of 56.2 kg, and average body height of 172.5 cm. The testing was preceded by a 10-minute warm-up and a 400-meter swim using any stroke, followed by two repetitions of a 15-meter sprint and a 35-meter easy swim. The experiment involving hypoxic conditions was carried out over a 3-week period / 21 days in February and March 2024. The participants were randomly assigned to three groups: RG1 underwent hypoxic controlled swimming training, RG2 underwent intermittent simulated hypoxic training using the ’AltitudeTechPortable 2020’ hypoxic generator, and RG3 served as a control group without any experimental intervention. The results indicate that the most significant average improvement in T1 was achieved by RG2 (+5.3%), in T2 by RG1 (+35.7%), and in T3 by RG1 (+14.3%). Based on the results, we may conclude that for performance swimmers, acute hypoxia in normoxic conditions, incorporated into swimming training in individual periods of 3 weeks and lasting 10-15 minutes per training session after warm-ups, appears to be most effective, especially when combined with intermittent hypoxia as implemented in this study, particularly for improving performance in the shortest 50-meter disciplines.enCC BY Creative Commons Attribution 4.0.
