Purpose
The present study aimed to measure diving response, CO2 sensitivity and forced vital capacity in male and female breath-hold divers (BHDs), and to determine their effect on breath-hold diving performance.
Methods
This study included 8 non-divers (NDs, 4 males and 4 females) and 15 BHDs (7 males and 8 females). For NDs, diving response was measured during breath-holding with facial immersion, whereas for BHDs CO2 sensitivity was also measured.
Results
Compared to NDs, BHDs showed a prominent diving response. In BHDs, no statistically significant sex differences were observed in diving response and CO2 sensitivity. Furthermore, a positive correlation was found between performance and the % forced vital capacity in BHDs.
Conclusion
It was suggested that % forced vital capacity contributed more significantly to performance than diving response and CO2 sensitivity. Furthermore, the higher performance of male divers compared to female divers may be due to the % forced vital capacity rather than the diving response and CO2 sensitivity.

性别差异对屏气潜水表现的影响
目的
本研究旨在测量男性和女性屏气潜水员 (BHD) 的潜水反应、CO 2敏感性和用力肺活量,并确定它们对屏气潜水表现的影响。
方法
这项研究包括 8 名非潜水员(ND,4 名男性和 4 名女性)和 15 名 BHD(7 名男性和 8 名女性)。对于 ND,潜水反应是在面部浸入屏气期间测量的,而对于 BHD,CO 2敏感性也被测量。
结果
与 ND 相比,BHD 表现出突出的潜水反应。在 BHD 中,在潜水反应和 CO 2敏感性方面未观察到具有统计学意义的性别差异。此外,在 BHD 的表现和百分比用力肺活量之间发现了正相关。
结论
有人提出,用力肺活量百分比对表现的贡献比潜水反应和 CO 2敏感性更显着。此外,与女性潜水员相比,男性潜水员的更高表现可能是由于%用力肺活量而不是潜水反应和 CO 2敏感性。
