| 内容記述 | The effect of six months of moderately intense aerobic training on 60-deg head-up tilt tolerance was assessed before and after 6 hrs of water-immersion deconditioning by comparing the orthostatic and fluid-electrolyte-endocrine responses of five male subjects before and after these tests. It was found that six months of training has no significant effect on 60-deg head-up tilt tolerance. Thus, during pretraining, the water immersion tilt-tolerance was found to decrease from about 74 min before to 34 min after water immersion, while during posttraining, water immersion tilt tolerance decreased from 74 min to 44 min. Fluid-electrolyte-endocrine responses were also essentially the same during all four tilts. Plasma volume decreased by 9.0 to 12.6 percent; plasma sodium and osmotic concentrations were unchanged; and serum protein and plasma renin activity increased. |
