三个月太极拳训练对中年人和老年人心率变异度、血脂肪以及内容摘要：

low frequency power • The spectral peaks ( Hz): total power Measurement (3) • The normalized highfrequency power ( highfrequency power / total power ) : vagal activity • The normalized lowfrequency power ( lowfrequency power / total power ) : sympathetic activity • The low /highfrequency power ratio : sympathovagal balance Measurement (4) • Biochemistry assays: total cholesterol (TC), HDLcholesterol (HDLC), low density lipoproteincholesterol (LDLC), triglyceride (TG), fasting blood sugar (FBS), uric acid (UA) • Immunoenzymometric assays: tumor necrosis factorα (TNFα), Interferonγ (INFγ） Statistics (1) • Descriptive statistics: median (25% —75%). • The MannWhitney rank sum test . • The Wilcoxon signed rank test. • p was considered statistically significant. Statistics (2) • The percentage change were calculated by using the following formula: •  =[(after before )(before )]100 Results • Table 1.
