Objective of the study was to rate and analyze combined functionality benefits of the Russian Snorkel New Breath breathing trainer applied on a systemic basis in a junior swimmers’ training system.
Methods and structure of the study. We sampled for the Russian Snorkel New Breath breathing trainer application model testing experiment the 15-18 year-old swimmers (n=17) qualified CMS and MS and split them up into Experimental (EG, n=8) and Reference (RG, n=9) Groups. The groups were trained twice a day for two weeks to increase their aerobic capacities, with the EG using the Russian Snorkel New Breath breathing trainer for 25% of the total training time, and RG trained traditionally. The group progresses were rated by the pre- versus post-experimental 6x100m breaststroke tests, with the average interval times and post-swimming 10s heart rate recovery time fixed.
The multisided effects of the Russian Snorkel New Breath breathing trainer application model were rated by multifunctional computerized ESTECK Test System (MULTISCANPRO™) to produce the following test rates: II - integral index, CI - cardiac index, CO - cardiac output, SV - stroke volume, HR - heart rate, LF / HF - autonomous nervous system frequency index; and SI - Stress Index. The test data were statistically processed using standard nonparametric criteria, with Z criterion used to rate significance of the test data differences.
Results and conclusions. The Russian Snorkel New Breath breathing trainer assisted training model was tested beneficial for the skilled junior swimmers as verified by the EG progress in the combined functionality tests with the simultaneous drops in the physiological costs for the muscular workloads in the trainings. The EG that used the Russian Snorkel New Breath breathing trainer on a systemic basis was tested with significant improvements in the circulatory system performance with growth in the functioning efficiency test rates – particularly in the autonomous nervous system regulation functions and psycho-functional status (stress controls) on the whole.
