Abstract

This paper reports the quantitative evaluation of the H-reflex exhibited by parabolic flight with exposure to micro and high-gravity. With respect to previous findings in parabolic flights and short-term space missions, the analysis focused on reflex activity in weightlessness. The aim of this study was to investigate the effect of gravity on H-reflex and motor evoked potentials (MEP) in soleus muscle (SOL) during parabolic flight.

摘要

本文报告了在抛物线飞行中暴露于微重力和高重力环境下对H反射的定量评估。关于之前在抛物线飞行和短期太空任务中的研究结果,分析聚焦于失重状态下的反射活动。本研究的目的是调查抛物线飞行期间重力对比目鱼肌(SOL)中H反射和运动诱发电位(MEP)的影响。
