| According to some correlation researches, we had found that Tai-chi softball can take good effect in improving middle-aged women bodies' function indicators, but the research results didn't turn out to be identical. In order to obtain a further confirmation about Tai-chi softball's effect in fitness, this paper studied the great effect of playing Tai-chi softball on middle-aged women lipids and physiological indicators.This paper enlisted 29 middle-aged women volunteers as an object of study, with normal cardiopulmonary ability and without disability who are not diseased seriously and don't often participate in sports exercise. They were divided into two groups: 46-55y and 56-65y. Subjects practices Tai-chi softball following the specially-assigned person in the morning and 40~50minutes a day, above 5 days a week, for 3 mouths. Then serum triglyceride(TG), total cholesterol(TC), low-density lipoprotein cholesterol(LDL-C) and high-density lipoprotein cholesterol(HDL-C) blood lipid indicators, and heart rate, blood pressure, vital capacity, the grip force etc some physiological indicators above were assayed before and after the training.Results:1) After Tai-chi softball training, 46-55y and 56-65y subjects serum TG and TC were very significantly decreased (P<0.01); HDL-C increased (P<0.01); the 46-55y group, LDL-C showed significance decreased (P<0.05), while 56-65y group, LDL-C decreased (P<0.01).2) After Tai-chi softball training, 46-55y group, subjects in a quiet pre-exercise heart rate decreased more (P<0.05), while the 56-65y group, subjects and exercise earlier there was a significant difference (P<0.01). Two subjects groups, systolic blood pressure, diastolic blood pressure in comparison with the previous exercise was significantly lower (P<0.01); vital capacity in comparison with the previous exercise very significance increase (P<0.01). 3) After Tai-chi softball training, the grip force and back edge, 46-55y and 56-65y groups, subjects in the 56-65y group, only the right-hand grip and back strength increased (P<0.05). Compared with 3 months ago, 46-55y and 56-65y groups, subjects movement and reaction time when the very significant decrease (P<0.01). Acoustic response of the two groups compared with the previous exercise significant difference (P<0.05), while the two light reaction time and exercise earlier there was a significant difference (P<0.01). Health station bent and stork stand, more than before exercise very significant increase (P<0.01).This study showed that Tai-chi softball may effectively reduce TG, TC, LDL-C, raise HDL-C, to improve the situation of middle-aged women blood lipid; to reduce heart rate, blood pressure, enhance vital capacity; It would have a certain role to raise the strength of middle-aged women force, agility, flexibility and other physical fitness. Tai-chi softball is a favorable fitness item.
