Influence of oxygen concentrate inhalation on performance in swimming underwater / Martin Pupiš, Zuzana Pupišová, Ratko Pavlović. -- © 2016, Univerzitet u Travniku. All rights reserved.The aim of the present study was to analyze the influence of oxygen concentrate inhalation on underwater swimming performance in students from the Department of Physical Education and Sports in BanskáBystrica. The test group consisted of 17 students (9 males: age = 21.14± 1.78 years, height= 176.4± 6.3 cm, weight= 66.2 ± 8.7 kg, and 8 women: age = 20.98± 1.54 years, height= 169.2± 4.2 cm, weight= 60.6± 4.5 kg). The test group carried out the testing over two consecutive days, where their task was to inhale oxygen concentrate/placebo for 2 minutes after a 5-minute collective warm-up and 500 meters of swimming. Subsequently, the role of the test group was to swim the maximum distance underwater with one inspiration and simultaneously push off the edge of the pool. Paired-Samples T-test (t, a = 0.05) was used to establish the significance of differences between the distance of underwater swimming after oxygen concentrate inhalation and distance after the application of the placebo. Cohen’s coefficient “d” was used for the calculation of effect size. Statistical analysis was realized with software IBM® SPSS® Statistics V19. The test results showed the average individual differences between oxygen and placebo of 6.89% (2.3 meters). Statistical analysis proved that the difference between the distance after oxygen concentrate inhalation and after the application of the placebo was significant (t(16) =10.101, p < 0.05, d = 2.45 – large effect).
