Purpose The purpose of this study is to find out the effect of Thera-Band exercise on cardiovascular autonomic nerve system activity with the Heart Rate Variability Power Spectral Analysis(HRV PSA) by using “The Biopac and Program”. Methods The old men were divided into two groups, Thera-Band exercise group(EG, n=13) and control group(CG, n=8). They participated in pre-test and after 8 weeks’ Thera-Band exercise. The Biopac System Test conducted for 5 minutes. Results: Heart Rate(HR) significantly effected after Thera-Band exercise. But no significant changes in CG. R-wave significantly effected after Thera-Band exercise. But no significant changes in CG. The present observations provide new
information(PS form) on the contribution of the cardiovascular autonomic function from Power Spectral Analysis(PSA) to the exercise responses. High frequency(HF, 0.15-0.4Hz), as the marker of parasympathetic nerve activity tone, is the distributed power 10-15~10-17. Low frequency(LF, 0.04-0.15Hz), as the marker of sympathetic nerve activity tone, is distributed power 10-12~10-10. The common frequency doma- in(0.135-0.3Hz) of PSN․SN, as the marker of parasympathetic and sympathetic nerve activity tone. is the distributed power 10-16~10-11. Conclusion From the discussions above results, we can conclude that Thera-Band exercise in old men induce the effect of autonomic nerve activity. These results are associated with increased and decreased HR and R-wave after Thera-Band exercise. Finally, in order to Normalized for the Power Spectrum, the further experimental work is needed to under-stand the possible mechanistic link between the cardiovascular autonomic function and the exercise responses. |
