大学生运动负荷心输出量和适宜运动量

Testing College Students′Cardiac Output Under Workload and Determining Optimal Amounts of Exercise for Them

为了观察大学生心脏的泵血功能,作者对133名男女大学生用心阻抗微分波法进行了踏车连续负荷无创伤性心输出量测定。根据测定结果,提出了男女大学生的适宜运动负荷量,以指导在实际锻炼中合理地安排运动强度和密度。

The cardiac pumping function in 133 male and female college students was observed by testingtheir non-invasive cardiac outputs by means of impedance cardiography while they worked on a bi-cycle ergometer continuously for acertain period of time. On the basis of the results achieved inthe test, optimal amounts of exercise were determined for students of both sexes so that they couldadjust the intensity and frequency of their training properly.
