Abstract:
Swimming is a widely practiced exercise in modern society, where there is a heightened interest in health. The exceptional benefits of swimming are well-known, yet the issue of water quality management inevitably arises due to its nature as an aquatic exercise. Several studies reported that chlorine disinfectants commonly used in swimming pool water disinfection could degrade into toxic disinfection by-products (DBPs) and suggested that the DBPs might induce respiratory disorders, including asthma. Conversely, there were also reports that the DBPs had no significant effects on respiratory conditions. In this study, we investigated the influence of swimming exercise and DBPs on asthma. The decomposition products had little effect on the number of T cells in various immune organs. However, swimming exercise was found to increase the cell count in proportion to the exercise duration. Nevertheless, there were no significant changes in other immune cells and the secretion of asthma-related cytokines. These findings indicate that the effects of swimming pool DBPs on respiratory conditions during swimming exercise are either negligible or absent, and instead, the immunological benefits gained through consistent swimming exercise outweigh any potential drawbacks.
摘要:
游泳是现代社会普遍实行的一项运动,对健康的兴趣越来越高。游泳的好处是众所周知的,然而,水质管理问题不可避免地出现,因为它是一项水上活动。一些研究报告说,游泳池水消毒中常用的氯消毒剂可以降解为有毒的消毒副产物(DBPs),并表明DBPs可能会引起呼吸系统疾病,包括哮喘.相反,还有报道称,DBPs对呼吸系统疾病没有显著影响.在这项研究中,我们研究了游泳运动和DBPs对哮喘的影响。分解产品对各类免疫器官中T细胞数目影响较小。然而,发现游泳运动与运动持续时间成比例地增加细胞计数。然而,其他免疫细胞和哮喘相关细胞因子的分泌均无明显变化.这些发现表明,在游泳运动期间,游泳池DBPs对呼吸状况的影响可以忽略不计或不存在,相反,通过持续的游泳运动获得的免疫益处超过了任何潜在的缺点。
