Application of breathhold in sports training of 10-12 year old children as a way to increase their functional endurance

Statement of the problem. The article describes an alternative and affordable method of hypoxic training through holding the breath on inhalation and exhalation, as a tool for developing endurance. The relevance of the topic is in the absence of a method that develops endurance and hypoxic characteristics with a sparing effect on heart rate (HR) and availability in use. Research methodology (materials and methods). Using hypoxic tests of Stange and Genchi (holding the breath on the inhale and exhale by the stopwatch), as markers that determine the development of endurance, we arranged the experiment. We divided 24 young men of volleyball players aged 10-12 into two groups, experimental and control, 12 people in each group with a uniform level of sports fitness. The arithmetic mean of indices in the introductory Stange samples in the control group and in the Genchi samples showed 1 minute 8 seconds and 31 seconds, respectively. In the experimental group, there were 48 seconds in the Barbell samples and 25 seconds in the Genchi samples, confirming the uniformity of training in the development of endurance. The experiment lasted three months, during which time the experimental group underwent breathing exercises on inhalation and exhalation, regulated by the time of 20 and 7 seconds, maximum in the corridor of execution, and the control group trained in the normal mode. At the end of the experiment, samples were taken, similar to the introductory ones. The average result of the breath holding time in the control group changed by 4 seconds in the Genchi and Stange samples, in relation to their own results, and the results of the experimental group in relation to their own results increased by 1 minute 13 seconds in the Stange sample and by 23 seconds in the Genchi sample. The values of the samples are detailed in Table. Research results. As a result of the study, the experimental group exceeded the control group in the samples with breath-holding during inhalation (Stange) by 47 seconds and breath-holding during exhalation (Genchi) by 31 seconds. This practically confirms the significance of hypoxic training with regulated breath holding to develop endurance. Conclusion. The experiment proves the effectiveness of alternative hypoxic training with regulated breath holding during inhalation and exhalation and contributes to the further study of the tool, which is available for material and technical use.
