目的:比较等张运动与等长运动对高血压患者的血脂及内皮素的影响,为高血压病运动处方的制定提供理论依据。方法:将45例老年高血压患者随机分成主要基线资料具有可比性的三组,A组采用等张练习,B组采用等长练习,C组采用等长练习+等张练习。观察运动训练16周后血脂及内皮素的变化。结果:A、B组对高血压患者的血脂有一定的改善作用,血浆内皮素降低(P<0.05);C组训练前后相比较,TC、LDL降低(P<0.05),TG显著降低(P<0.01),HDL则明显升高P<0.05),血浆内皮素显著下降(P<0.01)。结论:等张运动与等长运动相结合的全面康复训练方案可以有效改善高血压患者血脂及内皮素水平,有利于高血压病的康复,是高血压病运动处方的首选。
Objective: To compare the effects of isometric exercise and isometric exercise on the blood lipids and endothelin in hypertensive patients, and to provide a theoretical basis for the formulation of exercise prescriptions for hypertension. Methods: Forty-five elderly hypertensive patients were randomly divided into three groups with comparable baseline data. Group A used isometric exercises, Group B used equal length exercises, and Group C used isometric exercises with isotonic exercises. The changes of blood lipid and endothelin after 16 weeks of exercise training were observed. Results: Compared with before training, the levels of TC and LDL decreased (P <0.05) and the levels of TG decreased significantly in group A and B (P <0.05) <0.01), HDL was significantly increased P <0.05), plasma endothelin significantly decreased (P <0.01). Conclusion: A comprehensive rehabilitation training program combining isometric exercise with isometric exercise can effectively improve the level of blood lipids and endothelin in hypertensive patients and is beneficial to the rehabilitation of hypertension. It is the first choice of exercise prescription for hypertensive patients.
