The benefits of swimming have been extensively assessed. However, swimming pools contain chlorine and other irritating chemicals that may induce contact dermatitis. To evaluate the effect of a swimming training session on transepidermal water loss (TWEL) in swimmers compared to football players, elite swimmers and football players were invited to participate (58 athletes) in the study, where TEWL was measured before, immediately after, and 30 min after a 2 h training session. The probe was held on the dorsum of the hand, volar forearm, and on the antecubital flexure for 1 min. The volar forearm, antecubital flexure, and hand dorsum showed a significant increase in TEWL in swimmers in both measurements after training compared to baseline ( < 0.001). In football players, an increase in TEWL was observed on the hands' dorsum between baseline and after training measurements. The variations on TEWL levels before and immediately after the training session were higher among swimmers on the volar forearm ( = 0.002) and antecubital flexure ( = 0.019). Our findings support the effect of the training environment-swimming pool versus outdoor sports-on the skin barrier function, with an increase of transepidermal water loss immediately after exercise. Exposure to a swimming pool environment in a 2 h training session may lead to changes in skin barrier function.
游泳的益处已经得到了广泛的评估。然而，游泳池中含有氯和其他刺激性化学物质，可能会引起接触性皮炎。为了评估游泳训练对游泳运动员和足球运动员经表皮水分流失（TEWL）的影响，邀请了 58 名运动员（精英游泳运动员和足球运动员）参与研究，在 2 小时训练前后和 30 分钟后测量 TEWL。探头在手背、前臂掌侧和肘前窝保持 1 分钟。与基线相比，游泳运动员在训练后的两次测量中，前臂掌侧、肘前窝和手背的 TEWL 均显著增加（<0.001）。在足球运动员中，在手背的 TEWL 从基线到训练后测量之间增加。在训练前后，游泳运动员在前臂掌侧（=0.002）和肘前窝（=0.019）的 TEWL 水平变化更高。我们的研究结果支持训练环境——游泳池与户外运动——对皮肤屏障功能的影响，运动后立即增加经表皮水分流失。在 2 小时的训练中暴露在游泳池环境中可能会导致皮肤屏障功能的变化。
