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，但关于饮食和运动变化对心血管危险因素的影响的信息很少。本研究旨在探讨在立位状态下，膳食能量来源和运动能量消耗的变化是否会影响血浆瘦素浓度和血流动力学。训练组的总能量消耗高于正常对照组。血清瘦素水平与BMI高度相关。训练组血浆瘦素浓度和脂肪含量下降，活动度增加，血压迅速恢复，心率加快；饮食均衡摄入和体力活动增加等生活方式的改变降低了青少年血浆瘦素水平，改善了立位状态下的血流动力学。

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.
