摘要
间歇性高原暴露可改善运动员的有氧运动表现和血液参数。各种各样的低氧设备和模拟高原训练模型需要对其效果进行详细的研究,以达到最佳效果。这项研究的目的是调查在海平面条件下进行为期四周的训练营的效果,并结合在运动员夜间睡眠期间由缺氧机提供的常压缺氧。选取保加利亚国家队赛艇运动员16名,年龄17.13±0.83岁,分为对照组(n=8)和实验组(n=8),进行为期四周的缺氧治疗。在训练营开始和结束时,测量人体测量和血液学数据。在概念II划船测力仪上进行了次极限测试,并确定了体力工作能力和无氧阈值。结果表明:1)训练营结束后,有氧运动成绩在组内组间均无明显变化;2)训练营结束时,实验组血红蛋白浓度(156.25±4.11 vs 162.75±4.11 g/L, p<0.01)、红细胞计数(5.26±0.13 vs 5.49±0.10 g/L, p<0.01)升高有统计学意义。令人鼓舞的结果是,实验组的血携氧能力增加了,但这并没有导致工作能力的增加。进一步的研究应该提供在寻找最佳的低氧训练参数,不仅允许血红蛋白浓度的上升,而且血液流变学性质的保存。
Application of hypoxicators in the rowers’ training
Intermittent altitude exposure leads to improvements in aerobic performance and blood parameters of athletes. The variety of hypoxic devices and simulated altitude training models requires a detailed study of their effects to achieve the best results. The aim of this study was to investigate the effect of a four-week training camp at sea level conditions, combined with normobaric hypoxia, provided by hypoxicators during the night's sleep of the athletes. Sixteen rowers of the Bulgarian national team (17.13±0.83 years old) were divided into a control group (n=8) and an experimental group (n=8) subjected to hypoxia for a period of four weeks. At the beginning and end of the training camp, anthropometric and hematological data were measured. A submaximal test on the Concept II rowing ergometer was performed, and the physical work capacity and anaerobic threshold were determined. The results showed: 1) a lack of significant changes in the aerobic performance after training camp, both within and between groups; 2) at the end of the training camp in the experimental group a statistically significant increase in hemoglobin concentration (156.25±4.11 vs 162.75±4.11 g/L, p<0.01) and erythrocyte count (5.26±0.13 vs 5.49±0.10 g/L, p<0.01) was observed. The encouraging results regarding the higher increase in blood oxygen-carrying capacity in the experimental group did not lead to an increased working capacity. Further research should be provided in the search for optimal hypoxic training parameters, allowing not only a rise in hemoglobin concentration, but also the preservation of blood rheological properties.
