Breath-hold divers compete with regard to depth, time and/or distance. The present observations were carried out on athletes performing static apnea where they perform one breath-hold for as long a duration as possible with the body and face immersed in water. Heart rate was measured on eight competitors participating in the Swedish Championship in static apnea 2001, both during the competition and during a separate training session using the Polar NV system. The duration of apneas during the competition ranged from 3 minutes 27 seconds to 5 minutes 33 seconds. The divers exhibited significantly faster heart rates prior to and during the first 90 seconds of apnea in connection with competition, than during training. One subject experienced a loss of motor control during the competition. We suggest that mental stress in humans, caused here by a competitive situation, leads to an increase in the heart rate during apnea.
屏气潜水者在深度、时间和/或距离方面展开竞争。目前的观察是针对进行静态屏气的运动员开展的，他们将身体和面部浸入水中，尽可能长时间地进行一次屏气。使用 Polar NV 系统，在 2001 年瑞典静态屏气锦标赛的八名参赛选手比赛期间以及单独的训练环节中测量了心率。比赛期间屏气的持续时间从 3 分 27 秒到 5 分 33 秒不等。与训练期间相比，潜水者在比赛期间屏气前 90 秒以及屏气过程中心率明显更快。一名受试者在比赛期间出现了运动控制丧失的情况。我们认为，在此处由竞争情境导致的人类精神压力会使屏气期间心率增加。
