Available in PDF, EPUB and Kindle. Book excerpt: The purpose for this 30-day bed-rest study was to investigate the effects of short-term, high-intensity isotonic and isokinetic exercise training on maintenance of aerobic work capacity (peak oxygen uptake); muscular strength and endurance; and orthostatic tolerance, equilibrium, and gait. Other data were collected on muscle atrophy, bone mineralization and density, endocrine analyses of vasoactivity and fluid-electrolyte balance, muscle intermediary metabolism, and performance and mood of the subjects. Nineteen men (32-42 yr) were allocated into three groups: no-exercise control (peak oxygen uptake and isokinetic tests once/wk, N = 5), isotonic exercise training (electronic Quinton ergometer, supine, N = 7), and isokinetic exercise training (electronic Lido ergometer, supine, N = 7). The exercise training regimens were conducted near peak levels for 30 min in the morning and 30 min in the afternoon 5 d/wk. The protocol consisted of a 7-d ambulatory control period during which the subjects equilibrated on the standardized diet, 30 d of 6 degrees head-down bed rest, and a final 4.5 d of ambulatory recovery. Their diet consisted of commonly available fresh and frozen foods; mean caloric consumption of 2,678 +/- SE 75 kcal/d (control), 2,833 +/- SE 82 kcal/day (isotonic), and 2,890 +/- SE 75 kcal/d (isokinetic) resulted in mean weight losses during bed rest of 1.01 kg, 0.85 kg, and 0.0 kg, respectively. The results indicated that: (1) The subjects maintained a relatively stable mood, high morale, and high esprit de corps throughout the study. Scores improved in nearly all performance and mood tests in almost all the subjects. Isotonic training, as opposed to isokinetic exercise training, was associated with decreasing levels of psychological tension, concentration, and motivation, and with improvement in the quality of sleep. (2) Peak oxygen uptake was maintained during bed rest with isotonic exercise training; it was not maintained as well with isokinetic ( -9.0%) or no-exercise ( -18.2%) training. If a 9% reduction in aerobic power is acceptable, isokinetic exercise training could be used for maintenance of strength, endurance, and the reduced aerobic capacity in astronauts during flight. (3) In general, there were few decreases in strength or endurance of arm or leg muscles during bed rest, in spite of reduction in size (atrophy) of some leg muscles. (4) There was no effect of isotonic or isokinetic exercise training on orthostasis, because tilt-table tolerances were reduced similarly from 42-53 min to 30-34 min in the three groups following bed rest. (5) Bed rest resulted in significant decreases of postural stability and self-selected step length, stride length, and walking velocity, which were not influenced by either exercise training regimen. Pre-bed-rest responses were restored by the fourth day of recovery.
