摘要

摘要目的:研究在实验室条件下,水对照试验中克服2000 m距离的时间与x -法测定的厌氧阈值之间的相关性。材料和方法:包括收集和分析克服2000米距离所取得的时间和x法确定的无氧阈值,与每个参与者的个人能量和心率相关。2018年至2021年期间,来自保加利亚国家队的五名优秀男子赛艇运动员接受了审查。为了通过x法确定无氧阈值,我们使用了最大肺活量测定试验中每20秒记录一次的分钟肺通气和心率数据,并随强度的增加而增加。测试是在概念II划船机和测量肺通气和心率的设备上进行的。结果:皮尔逊系数r = .457(= .05)表明,克服2000m距离的时间与x法测定的无氧阈值下记录的心率之间存在中等相关性。结论:x法测定无氧阈值是一种控制训练过程的相关方法,对判定赛艇运动员的功能状态具有预测价值。与传统气体分析仪的成本相比,其优点是使用的诊断设备的成本显着降低。

CORRELATION BETWEEN CONTROL TEST TIMES RELATED TO THE ANAEROBIC THRESHOLD DETERMINED BY THE X-METHOD IN ROWERS
ABSTRACT Aim: The aim of the study is to investigate the correlation between the times for overcoming the distance of 2000 m achieved in control tests on the water and the anaerobic threshold determined by the X-method in laboratory conditions. Material and Methods: Includes collection and analysis of the times achieved in overcoming the distance of 2000 m and the anaerobic threshold determined by the X-method, related to the individual ergometric power and heart rate for each participant. Five elite rowers from the National Team of Bulgaria, men, for the period from 2018 to 2021 were examined. To determine the anaerobic threshold by the X-method, we used the data from minute pulmonary ventilation and heart rate recorded every 20 s during the maximum spiroergometric test with increasing intensity. The test was performed on a Concept II rowing machine and equipment measuring pulmonary ventilation and heart rate. Results: The Pearson coefficient r = .457 ( = .05) shows a moderate correlation between the times for overcoming the distance of 2000 m, and the heart rate recorded at the anaerobic threshold determined by the X-method. Conclusion: The X-method for determining the anaerobic threshold is an relevant method in the control of the training process and has prognostic value in determining the functional status of rowers. An advantage is the significantly lower cost of the used diagnostic equipment compared to the cost of a conventional gas analyzer.
