摘　　要：目的 观察利用短臂离心机开展前庭刺激训练6d对男性心血管功能、心率变异(HRV)性和前庭症状的影响。方法 12名男性被试者2人一组进行连续6d人体短臂离心机暴露,足水平2Gz,持续10min,复合每分钟向左或向右交替转头45°1次。记录实验前后被试者血压、心率等变化,并进行HRV性分析,同时进行前庭功能评价。结果 与训练前相比,短臂离心机前庭刺激训练6d后被试者前庭症状明显减轻,前庭症状评分显著降低(P<0.05);而被试者心率、舒张压、心脏泵血功能和HRV指标较训练前均无显著变化。结论 短臂离心机前庭刺激训练可显著增强前庭功能稳定性,但对心血管功能没有明显影响。AIM To investigate the effects of short-arm centrifuge combined with vestibular stimulation training on cardiovascular function, heart rate variability, and vestibular symptoms in males. METHODS Twelve male subjects were exposed to a short-arm centrifuge for 6 consecutive days at a foot level of 2 Gz for 10 minutes, turning their heads 45 degrees to the left or right every minute. The changes of blood pressure and heart rate before and after the experiment were recorded. The heart rate variability(HRV) was analyzed and the vestibular function was evaluated. RESULTS Compared with those in the pre-training period of exposure to compound vestibular stimulation by short-arm centrifuge, the subjects’ heart rate, diastolic blood pressure, low frequency power of heart rate variability and low frequency power/high frequency power did not reach significant levels. The scores of vestibular symptoms were significantly lower than those before the training of the short-arm arm centrifuge(P<0.05). CONCLUSION Short-arm centrifuge exposure to combined vestibular stimulation does not have much effect on cardiovascular system.
