Effect of Life Style Modification on the Cardiovascular Risk Factors in Young People

虽然众所周知，年轻人的生活方式，如运动和饮食对健康很重要，但关于饮食和运动改变对心血管风险因素的影响的信息很少。本研究旨在探讨饮食能量来源的改变和运动介导的能量消耗是否影响直立状态时血浆瘦素浓度和血流动力学。训练组总能量消耗明显高于正常对照组。血清瘦素浓度与BMI之间存在高度相关性。训练组血浆瘦素浓度和脂肪量下降，活动量增加，血压恢复，心率加快。生活方式的改变，包括平衡饮食摄入和增加体力活动，降低了年轻人的血浆瘦素浓度，改善了直立状态时的血流动力学。

Although it is known that life style such as exercise and diet in the young people is important for health, little information is available on the effects on the cardiovascular risk factors of changes in Diet and exercise. This study was designed to investigate whether change in dietary energy sources and exercise-mediated energy expenditure affect plasma leptin concentration and hemodynamics during orthostatic state.Total energy consumption in training group more increased than in normal controls. There was a highly correlation between serum leptin concentration and BMI. Plasma leptin concentrations and fat mass decreased as well as increased activity in training group, blood pressure recovered and heart rate increased very promptly.The changes in life style consisting of balanced intake of diet and increased physical activity reduced plasma leptin concentrations in young people and improved the hemodynamics during orthostatic state.
