PURPOSE: To evaluate the effects of neck upright stability training on autonomic nervous activities of the middle aged and elderly women.
METHODS: We recruited 60 active female subjects from a senior club without past history of major neck injuries. The subjects were randomly assigned into two groups, experimental and control. Thirty two subjects, 16 of each group, finished a 4-week training program. The experimental group practiced neck upright stability training for four weeks, 3 times a week, and the control group did a control exercise. Resting heart rate variability (HRV) was measured for 5 minutes in a supine position by WG-MD-ANSA-01 (Tatung Co., Taipei, Taiwan) before and after the training program. Data were reduced and represented as percentages of change, which were tested by the independent t test (Spss12.0). Thealevel was set at 0.05 and p < 0.05 was considered to be statistically significant.
RESULTS: No significant difference in demographic data was noted between two groups. The ANA parameters include TP, VLFp, LFp, HFp, RRI, LF:HF, LFnu % and HFnu %. Significant differences between two groups were found only in percentages of change in LFp.
CONCLUSION: Neck upright stability training may increase the autonomic nervous activity of the middle- aged and elderly women, especially on SNA (sympathetic nervous activity). Clinical significance shall be studied further.Key words: HRV, ANA, Neck training.
