本研究是一项生理和心理联合实验，旨在确定热、噪音和体育活动共同影响下人体生理和心理功能的变化。在一个气候室中模拟了7种不同的实验情况，包括三个自变量的不同配置：热量（40°C）、噪音（98 dB）和体力消耗（最大吸氧量v02 max的30%）。监测5个心理变量（临界闪烁融合- cff、手颤、反应时间、主观气候评价和给定条件负荷的主观评价）和2个生理变量（心率和直肠温度）。结果表明，当施加多个实验变量时，CFF显著改变（增加）。这些变化与主观气候评价和给定条件负荷主观评价的显著变化相一致。精神运动功能（手震颤和反应时间）无明显变化。观察到的生理参数均未超过临界值。结果表明，CFF可作为一种心理物理负荷指标。
This study was a joint physiological and psychological experiment undertaken to determine changes in physiological and psychological human functions under the combined influence of heat, noise, and physical activity. Seven experimental situations were simulated in a climatic chamber with different configurations of three independent variables: heat (40 °C), noise (98 dB), and physical effort (30% of maximum volume of oxygen uptake-V02 max). Five psychological variables (critical flicker fusion-CFF, hand tremor, reaction time, subjective climate evaluation, and subjective evaluation of the given condition load) and two physiological variables (heart rate and rectal temperature) were monitored. Results indicate that CFF changed (increased) significantly when more than one experimental variable was applied. These changes coincided with significant changes in both subjective climate evaluation and subjective evaluation of a given condition load. There were no significant changes in psychomotor functions (hand tremor and reaction time). None of the observed physiological parameters were above the critical value. The results suggest that CFF can be treated as a psychophysical load indicator.
