摘要

背景:运动性支气管收缩(EIB)是优秀运动员的常见问题。EIB发展的经典途径包括渗透和热理论以及气道上皮损伤的存在,局部失水是EIB的主要触发因素。本研究旨在探讨全身水化对肺功能的影响,并确定它是否可以逆转脱水引起的肺功能改变。材料和方法:本随访研究在无哮喘和/或特应性反应史的职业自行车运动员中进行。记录所有参与者的人体测量特征,并确定训练年龄。此外,肺功能测试和特异性标志物,如分数呼出一氧化氮(FeNO)和免疫球蛋白E (IgE)进行测量。所有的运动员都进行了身体成分分析和心肺运动测试(CPET)。CPET结束后,分别于第3、5、10、15、30分钟进行肺活量测定。本研究分为水化前后两个阶段。与CPET前的肺活量测定结果相比,CPET后一秒钟用力呼气量(FEV1)下降≥10%和/或最大轻度呼气流量(MEF25-75)≥20%的骑行者,在15-20天内重复测试,并按照补水说明进行。结果:100名男性自行车运动员(n = 100)参加了a阶段。运动后,所有肺量指标均下降(p < 0.001)。在B期,水化后,在所有比较中,肺活量值的变化均显著低于A期(p < 0.001)。结论:本研究结果提示职业自行车运动员对呼吸功能有不利影响。此外,我们发现全身水合作用对骑自行车者的肺活量测定有积极作用。特别值得关注的是小气道,它们似乎单独受到影响,或与FEV1的减少联合受到影响。我们的数据表明,水合作用后肺功能得到改善。

Effect of Hydration on Pulmonary Function and Development of Exercise-Induced Bronchoconstriction among Professional Male Cyclists.

Background: Exercise-induced bronchoconstriction (EIB) is a common problem in elite athletes. Classical pathways in the development of EIB include the osmotic and thermal theory as well as the presence of epithelial injury in the airway, with local water loss being the main trigger of EIB. This study aimed to investigate the effects of systemic hydration on pulmonary function and to establish whether it can reverse dehydration-induced alterations in pulmonary function.

Materials and methods: This follow-up study was performed among professional cyclists, without a history of asthma and/or atopy. Anthropometric characteristics were recorded for all participants, and the training age was determined. In addition, pulmonary function tests and specific markers such as fractional exhaled nitric oxide (FeNO) and immunoglobulin E (IgE) were measured. All the athletes underwent body composition analysis and cardiopulmonary exercise testing (CPET). After CPET, spirometry was followed at the 3rd, 5th, 10th, 15th, and 30th min. This study was divided into two phases: before and after hydration. Cyclists, who experienced a decrease in Forced Expiratory Volume in one second (FEV1) ≥ 10% and/or Maximal Mild-Expiratory Flow Rate (MEF25-75) ≥ 20% after CPET in relation to the results of the spirometry before CPET, repeated the test in 15-20 days, following instructions for hydration.

Results: One hundred male cyclists (n = 100) participated in Phase A. After exercise, there was a decrease in all spirometric parameters (p < 0.001). In Phase B, after hydration, in all comparisons, the changes in spirometric values were significantly lower than those in Phase A (p < 0.001).

Conclusions: The findings of this study suggest that professional cyclists have non-beneficial effects on respiratory function. Additionally, we found that systemic hydration has a positive effect on spirometry in cyclists. Of particular interest are small airways, which appear to be affected independently or in combination with the decrease in FEV1. Our data suggest that pulmonary function improves systemic after hydration.
