Description
OBJECTIVES:
The success of the Apollo program overall, and the lunar landing missions specifically, was dependent upon the ability of the astronauts to engage in long and strenuous hours of extravehicular activity (EVA). Although it was expected that reduced gravity would make some tasks less difficult, it was noted that reduced suit mobility and the complexity of the mission timeline indicated that metabolic activity would exceed resting levels for extended periods of time. Because the type and extent of physiological dysfunction that could result from habitability in a zero-G environment had not yet been established, appropriate physiological tests were performed within Apollo program constraints to ascertain whether the physiological response of the crewmen to exercise was altered as a result of space flight. The objective of this investigation, performed during the Apollo 7-11 and 14-17 missions, was to evaluate the physiological response to exercise pre- and postflight in order to assure the success of lunar surface extravehicular activity (EVA).
