Abstract

Objective: The aim of this study was to investigate scuba diving induced exercise response in novice divers as required in open water scuba diving certification. Methods: Maximal cardiopulmonary exercise test (CPET) was performed in 30 novice divers before and within 24 hours after a standard scuba diving open water certification diving protocol of four open water dives. Results: A significant increase in maximal oxygen consumption (VO2max) in mL·kg-1·min-1 after scuba diving training [25.84 (6.0) vs. 27.04 (7.0)] (p<0.05) suggestive of an increase in exercise performance. Ventilatory drive (VE/VCO2) also showed a significant increase 27.95 (2.7) vs. 30.07 (5.3). Ventilatory anaerobic threshold (VAT), blood pressure and lung function parameters showed no significant differences with open water scuba diving certification training. Conclusion: In novice divers, repeated training exposure during open water scuba diving certification results in increased cardiorespiratory fitness. Although further corroborating studies are needed, this would suggest that recreational scuba diving may be an option for exercise promotion in the future.

娱乐性水肺潜水对马来西亚新手心肺功能的影响

目的：本研究旨在调查开放水域水肺潜水证书要求的新手水肺潜水诱导的运动反应。方法：对30名新手潜水员进行最大心肺运动测试（CPET），测试时间为4次公开水域潜水的标准水肺潜水公开水域认证潜水协议之前和之后的24小时内。结果：水肺潜水训练后最大耗氧量（VO2max）显著增加（单位：mL·kg-1·min-1）[25.84（6.0）vs.27.04（7.0）]（p<0.05），提示运动成绩提高。通气驱动（VE/VCO2）也显示出显著增加27.95（2.7）比30.07（5.3）。通气无氧阈值（VAT）、血压和肺功能参数与开放水域水肺潜水认证训练没有显著差异。结论：对于新手潜水员来说，在公开水域水肺潜水认证期间重复训练暴露会提高心肺健康。尽管还需要进一步的确证研究，但这表明娱乐性水肺潜水可能是未来促进锻炼的一种选择。
