AIM To investigate the effects of short-arm centrifuge combined with vestibular stimulation training on cardiovascular functions, 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.
