    CBS-SM Determine if there are decrements in performance on functional tasks after long-duration spaceflight. Determine how changes in physiological function, exercise activity, and/or clinical data account for these decrements. An aggressive in-flight exercise program seems to be only partially effective in maintaining postflight aerobic capacity, and its effects on orthostatic tolerance are largely unknown. On the Russian space station Mir, cosmonauts and astronauts currently exercise for almost 2 hours daily during flight and use saline loading and anti- g garments.

The purpose of this study was to determine the effect of self-selected in-flight exercise on the cardiovascular responses to standing after spaceflight. Secondarily, we examined pre- and postflight stand test responses of a small number of crewmembers who performed extravehicular activities.

Thirty crewmembers performed self-selected in-flight exercise and maintained exercise logs to monitor their exercise intensity and duration.

A 10min stand test, preceded by at least 6 min of quiet supine rest, was completed 15 d before launch (PRE) and within four hours of landing (POST).

Johnson Space Center, [] Description: vi, 20 p.: ill. To date, there have been no space flight experiments that have specifically addressed the effect of exercise on postflight orthostatic responses. Previous studies have not controlled or reported pre- or in-flight exercise habits of Space Shuttle crew members.

To understand the effects of longer-duration spaceflight on baroreflex function, we measured R-R interval power spectra, antecubital vein plasma catecholamine levels, carotid baroreceptor-cardiac reflex responses, responses to Valsalva maneuvers, and orthostatic tolerance in 16 astronauts before and after shuttle missions lasting days.

During the day preflight period, five of the thirty-three Apollo crewmen had dental problems requiring treatment. One preflight and one postflight occurrence of pulpitis could have caused significant crewmember impairment if the pulpitis had occurred during a flight.

Effects on bone structure and function. Although exercise on Earth has improved calcium retention, 47 extensive use of the cycle ergometer and treadmill exercise in flight failed to eliminate postflight bone density losses. 21 Although phosphorous intakes were at or above daily requirements, inadequate dietary calcium intake may have contributed to in-flight bone loss because nutritional data Cited by: Some space flight missions have provided physiologic data, including cardiovascular data, from the spacefarers.

In fact, some missions have provided laboratories for systematic study of cardiovascular responses and adaptation to space flight.

However, the opportunity to obtain physiologic data from people in space is a rarity. It is important to remember that the population sample sizes are.

The arrhythmias occurred during effort tests, extravehicular activities (EVAs), lower body negative pressure sessions, and throughout the entire mission.

These included two consecutive PVCs in one astronaut during exercise and an episode of atrioventricular dissociation preceded by sinus bradycardia in two astronauts.
