| Objective:To discuss the effects of Tai Chi Chuan(TCC)on brain functional connection in middle-aged and elderly people by using near-infrared spectroscopy(NIRS)to collect the data of ordinary people and TCC practitioners.Methods:40 subjects took part in this study aged 50-60 years,22 ordinary people and 18 TCC practitioners.Using multichannel NIRS blood oxygen detection equipment to detect cerebral blood oxygen signal,which were analyzed in five frequency intervals by wavelet coherence(WCO)to evaluate differences.Results:(1)TCC group was significantly higher than ordinary people in the visual space/execution function(F=11.031,P=0.002),memory(F=6.630,P=0.014),total score(F=32,051,P=0.000).(2)TCC group in the LMC-LOC(F=4.333,P=0.045)?LMC-RMC(F=4.360,P=0.044)?LMC-RPFC(F=20.928,P=0.000)?LOC-RMC(F=5.372,P=0.027)?LOC-RPFC(F=31.040,P=0.000)?LPFC-RPFC(F=205.903,P=0.000)?LPFC-LMC(F=22.232,P=0.000)?LPFC-LOC(F=28.277,P=0.000)?LPFC-RMC(F=31.225,P=0.000)?LPFC-R0C(F?11.460,P =0.002)?RMC-RPFC(F =33.642,P =0.000)and ROC-RPF(F =10.169,P=0.003)was significantly higher than ordinary people in I;TCC group in the LPFC-RPFC(F=4.588,P=0.039)was significantly higher than ordinary people in II;TCC group in the LMC-LOC(F=5.608,P=0.024)?LMC-RMC(F=36.563,P=0.000)?LOC-RMC(F=4.163,P=0.049)?LOC-ROC(F=5,112,P=0.030)?LPFC-RPFC(F=49.647,P=0.000)and RMC-RPFC(F=9.961,P=0.003)was significantly higher than ordinary people in III;TCC group in the LMC-LOC(F=4.272,P=0.046)?LMC-RMC(F=28.999,P=0.000)?LOC-RMC(F=5.241,P=0.028)?LOC-ROC(F?12.667,P=0.001)?LPFC-RPFC(F=29.420,P=0.000)?LPFC-LMC(F=5.431,P=0.026)and RMC-RPFC(F=6.791,P=0.013)was significantly higher than ordinary people in IV;TCC group in the LMC-LOC(F=8.815,P=0.005)?LMC-RMC(F=38.244,P=0.000)?LOC-RMC(F=13.061,P=0.001)?LOC-ROC(F?12.667,P=0.001)?LPFC-RPFC(F=47.907,P?0.000)?LPFC-LMC(F?13.479,P=0.001)?LPFC-RMC(F=10.578,P=0.00· 003)?RMC-RPFC(F =10.603,P=0.003)and RMC-ROC(F=5.338,P =0.027)was significantly higher than ordinary people in V.(3)TCC movement state in the LPFC-RPFC(F=4.78,P=0.034)was significantly higher than TCC resting 3 state in I;TCC movement state in the LMC-LOC(F= 7.135,P = 0.01),LMC-RMC(F=6.293,P=0.016,LMC-ROC(F=7.639,P=0.008),LMC-RPFC(F?10.917,P ?0.002),LOC-RMC9 F =6.207,P =0.016),LOC-ROC(F =6.049,P =0.018),LOC-RPFC(F =4.599,P =0.037),LPFC-RPFC(F =4.415,P =0.041),LPFC-LMC(F=6.947,P=0.011),LPFC-LOC(F=7.978,P=0.007),LPFC-RMC(F?10.28,P=0.002),LPFC-ROC(F?10.860,P=0.002)?RMC-RPFC(F=4.822,P=0.033),RMC-ROC(F =4.822,P =0.033),ROC-RPFC(F =7.017,P =0.011)was significantly higher than TCC resting state in IV;TCC movement state in the LMC-LOC(F=7.455,P=0.009),LMC-RMC(F?7.786,P=0.008),LMC-ROC(F=7.563,P=0.008),LOC-RMC(F=4.94,P?0.031),LOC-RPFC(F=4.833,P =0.033),LPFC-LMC(F =13.255,P =0.001),LPFC-LOC(F =7.054,P=0.00l),LPFC-RMC(F =5.96,P =0.018),RMC-RPFC(F =5.009,P=0.030),ROC-RPFC(F?5.644,P=0.022)was significantly higher than TCC resting state in V.Conclusion:(1)TCC practitioners have a stronger cognitive function,such as spatial/executive function and memory,than ordinary people.(2)TCC can enhance brain functional connections in prefrontal cortex?motor cortex and occipital cortex.(3)TCC mainly affected brain functional connection by its important influence on the cardiac activity?neural activity and endothelial cell metabolic activity. |
