INTRODUCTION
The objective of this study was to observe the differences in the biodynamic responses of male and female crewmembers during a simulated Soyuz spacecraft (short-duration flights) impact landing.
METHODS
There were 16 volunteers (8 men and 8 women) recruited to sit in a pseudo-supine position and be exposed to several impact acceleration pulses. The acceleration peaks ranged from 7.7 to 11.8 g with a duration of around 50 ms. Acceleration responses from the drop platform and seat, and at the volunteers' head, shoulder, chest, and ilium were measured.
RESULTS
Results indicated that there were significant gender-based differences in the peak acceleration measured from volunteers' shoulders and iliums. The peak decelerations measured at the head and ilium were relatively higher than those measured at other levels on the seat.
DISCUSSION
It was recommended that more attention be focused on the sex differences of biodynamic responses of crews in the study of new protective designs for space capsule and personal life support equipment.
引言
本研究的目的是观察男性和女性机组人员在模拟联盟号飞船（短期飞行）撞击着陆过程中的生物动力学反应差异。
方法
招募了16名志愿者（8名男性和8名女性），让他们以假仰卧姿势暴露于几个冲击加速度脉冲中。加速度峰值范围为7.7至11.8g，持续时间约为50毫秒。测量了下降平台和座椅以及志愿者头部、肩部、胸部和髂骨处的加速度响应。
结果
结果表明，从志愿者肩部和髂骨测量的峰值加速度存在显著的性别差异。在头部和髂骨处测量的峰值减速度相对高于在座椅其他位置测量的值。
讨论
建议在研究太空舱和个人生命支持设备的新防护设计时，更多地关注机组人员生物动力学反应的性别差异。
