Abstract : During 'submaximum' loading tests of 20-30 min duration at simulated altitude (312 mm. Hg), on the tilt table, during acceleration (2.5 + Gz), and during exercise (17 mkp/sec) at sea level and at moderate simulated altitude (578 mm. Hg), heart rates were significantly lower for highly trained athletes, 20-25 percent, than in non-athletes. In maximum tolerance tests, however, there was found only a significant difference between the two groups for maximum oxygen uptake at physical exercise, but no indication was seen for a positive cross-adaption effect of physical exercise training on the other stressors. Statistical analysis of the correlation between heart rate responses to the different stressors and the corresponding tolerances proved negligible relationships only; whereas heart rates were always highly dependent on sea level VO2 max(r = -0.61 to -0.83). The results do not support the idea of an improvement of human tolerance to environmental extremes by physical exercise training. (Author)
