Title Locomotion while load-carrying in reduced gravities
Bibliographic information Oct. 1996, Vol.67, No.10, Section 1, p.940-946. Illus. 9 ref.
Abstract Six subjects ran or walked underwater on a treadmill in simulated reduced-gravity levels while carrying a range of loads. Energy expenditure, calculated from measured oxygen consumption, was positively correlated with gravity-level, speed of movement and load size. The data are used to project that individuals in average physical condition will be able to walk for 8h on the moon while carrying up to 170% of their bodymass without undue fatigue, and on Mars with up to 50% of their body mass. Implications for the design of portable life support systems are discussed.
