Eight subjects participated in one control and three rotation trials on a short-arm centrifuge such that the Gz levels at the feet were 0.5, 1.0, and 1.5 G. Trials consisted of 30 minutes of supine rest, 1 hour of rotation (or in the control, 30 additional minutes of rest and 30 minutes of standing), and a final 30-minute rest period. Measurements of heart rate, calf impedance, calf volume, and blood pressure support the findings that the highest G level is similar to standing and that the lower G levels fail to produce significant effects.
八名受试者在短臂离心机上参加了一次对照试验和三次旋转试验，使得脚部的Gz水平分别为0.5G、1.0G和1.5G。试验包括30分钟的仰卧休息、1小时的旋转（或者在对照试验中，额外30分钟的休息和30分钟的站立）以及最后的30分钟休息期。心率、小腿阻抗、小腿体积和血压的测量结果支持了以下发现：最高G水平与站立相似，而较低的G水平未能产生显著影响。
