摘要：Salisbury T, Baptista RR, Fei J, Susin F, Russomano T. Physiological Aspects of Walking in Simulated Hypogravity. JEPonline 2015;18(2):13-24. The purpose of this study was to compare the differences in gait between land (1G), Lunar (Lunar G), and Martian (Mars G) based ambulation. Nine subjects (mean age = 24.2 ± 3.4; weight = 69.88 ± 14.65kg; height = 163.22 ± 7.8cm; 5 male and 4 female) were placed in a Body Suspension Device (BSD) and had baseline oxygen consumption (VO2) measured along with measures of comfort, pain, and exertion. Then, the BSD was engaged and the subjects underwent 10 min of walking at a self-selected speed in a simulated Mars G or Lunar G environment. The findings demonstrate that as gravity is decreased, self-selected walking speed decreases. However, there was no significant difference in relative and absolute VO2 between Lunar G and Mars G. The experiment will be repeated using a lower body positive pressure device that will enable the comparison of results.
