Although it is known that alterations in grip strength occur under a number of conditions, little is known about relationships between grip strength and sexual arousal. This relationship was investigated in 30 healthy heterosexual males, who viewed both erotic and nonerotic videos. A questionnaire was used to assess the extent of sexual arousal. The grip strengths of both hands were measured with a five-position (P1-P5) dynamometer, before and after watching the videos. After watching the erotic video, there was a statistically significant reduction in grip strength for the P2 position, with nonsignificant overall reductions in grip strength for all other positions tested. No such effect was observed in control tests. The results indicate that during sexual arousal, the neural system is likely to reduce the output to muscles not directly related to sexual function, presumably to enhance the physiological responses of sexual arousal.
尽管已知握力在多种情况下会发生变化，但对于握力与性唤起之间的关系却知之甚少。在30名健康的异性恋男性中对这种关系进行了研究，他们观看了色情和非色情视频。使用问卷来评估性唤起的程度。在观看视频前后，用五位（P1 - P5）测力计测量双手的握力。观看色情视频后，P2位置的握力有统计学上的显著降低，而测试的所有其他位置的握力总体降低不显著。在对照测试中未观察到这种效应。结果表明，在性唤起期间，神经系统可能会减少对与性功能无直接关系的肌肉的输出，大概是为了增强性唤起的生理反应。
