| 内容記述 | There are evidences suggesting that endurance-trained athletes (ET) fail to maintain blood pressure responses to gravitational challenges such as head-up tilt, standing, or lower body negative pressure. The purpose of the present study was to examine whether gravitational intolerance in ET was due to a blunted carotid baroreceptor cardiac responsiveness. Eight ET females (long distance runners, 18.4±0.2 y.o.) and seven endurance-untrained females (UT 20.4±0.9 y.o.) participated in the experiment. Carotid baroreceptor-cardiac responses were estimated by using a neck chamber. R-R intervals were plotted against carotiddistending pressures and the response was analyzed by applying a four-parameter sigmoidal logistic function. The maximal gain of the curve in ET group was greater (P<0.05) than that of UT group, indicating increased baroreflex sensitivity. The centering point of the curve, an indicator of the operating point, was identical. There was a significant correlation between maximal 02 consumption and maximal gain (r=0.693, P<0.005). These results may suggest that attenuated baroreflex control of the heart rate in ET is not responsible for the mechanisms of the gravitational intolerance. |
