AIM To explore the effect of progressive 3D roller training on stability of vestibular function and cardiovascular regulation in men.
METHODS Twelve healthy male volunteers with poor vestibular stability were trained by using the progressive 3D roller training program once a day for six days. The vestibular function and cardiovascular regulation of the subjects were evaluated by electric swivel chair before and after training. The changes of vestibular function grading, Graybiel motion sickness score, blood pressures, heart rates and heart rate variability were observed during the above processes.
RESULTS Compared with the data before training, the Graybiel motion sickness scores of subjects after six days of 3D roller training decreased significantly (P<0.05). And the qualification rate of vestibular function increased from 66.7% before training to 91.7%. Before training, the subjects’ systolic and diastolic blood pressures increased significantly after the electric swivel chair test (P<0.05). LFn during the test of electric swivel chair was significantly lower than that before the test and LFn after the test was significantly higher than that during the test (P<0.05). HFn during the test was significantly higher than that before the test and HFn after the test was significantly lower than that during the test (P<0.05). After training, the blood pressures and heart rates of the subjects did not change significantly. LFn after the test was significantly higher than that before and during the tests (P<0.05), HFn after the test was significantly lower than that before and during the tests (P<0.05) and LF/HF after the test was significantly higher than that during the tests before and after training (P<0.05).
CONCLUSION Progressive 3D roller training can improve vestibular stability and enhance cardiovascular regulation in men.
