Abstract:

Twelve male subjects participated in two identical series to determine the value of exercising four hours daily at one-half Earth gravity simulated to prevent loss of exercise capacity and orthostatic tolerance when exposed to 14 days of simulated weightlessness. In one series four subjects exercised at half-gravity HGE subjects on treadmills mounted in a human centrifuge and four exercised on treadmills mounted on inclined planes in the other series the subjects switched exercise devices. Four subjects served as no- exercise controls throughout both series. Additional measurements included plasma volume and red cell mass, urinary sodium and potassium, and peripheral renin activity. The results are discussed in terms of their significance for long-range plans involving the use of artificial gravity as a countermeasure on space missions. Modified author abstract
