冬泳对泸州地区正常中老年人血压和血糖的影响

目的观察冬泳对泸州地区正常中老年人血压、脉搏、血糖的影响,探讨冬泳对预防高血压、预防糖尿病的一些作用机制。方法选择泸州地区47～70岁长期坚持冬泳者68人,分别测量水温为4℃～8℃入水前即刻、出水后即刻、出水后30min的收缩压、舒张压变化情况;分别于冬泳前及冬泳3个月后测定空腹血糖、餐后2h血糖,测定体重、腹围。结果冬泳者出水后即刻收缩压、舒张压较入水前即刻明显升高,脉搏明显加快,离水30min后血压渐恢复正常;冬泳3月后空腹血糖平均下降17.90%,餐后2h血糖平均下降13.27%;冬泳前冬泳者腰围为(85.75±7.47)cm,冬泳3月后腰围为(81.27±7.86)cm;冬泳前冬泳者体重指数为(25.36±3.63)(kg/m2),冬泳3月后为(24.24±2.72()kg/m2)。结论冬泳对维护正常人的血压可产生积极作用;冬泳可降低体重,亦有一定降低血糖的作用,可预防糖尿病;坚持冬泳可增强体质。

Objective To observe the effects of winter swimming on blood pressure, pulse, blood sugar for the normal middle and old of Luzhou area, discusses to prevent high blood pressure and diabetes action mechanism. Methods Choose 68 winter swimmers who are 47-70 years old. The water temperature was measured for the 4℃ -8℃ .They were measured the systolic and diastolic blood pressure into the water immediately before, immediately out off the water and out off the water after 30 minutes .Respectively, before winter swimming and winter swimming after 3 months fasting glucose, 2-hour postprandial blood glucose, body weight, and abdominal circumference were measured. Results Outing offthe water immediately, the swimmers whose systolic and diastolic blood pressure were significantly higher than before entering the water ,they have accelerated pulse.Outing off the water their blood pressure gradually returned to normal. After 3 months ,fasting glucose fell by an average 17.90%, 2-hour postprandial blood glucose decreased 13.27%.Before winter swimming , the waist sizes of swimmers were of （85.75±7.47） （cm）, after 3 months their waist sizes were of（81.27±7.86）; Before winter swimming, their weight index was of （25.36±3.63） （kg/m2）, and after March was of （24.24±2.72） （kg/m2）. Conclusion Winter swimming in regulating normal blood pressure has a positive effect, it can lower blood sugar, weight and prevent diabetes.
