大学生心泵功能现状特点及体育锻炼对策

CURRENT CHARACTERISTICS OF COLLEGE STUDENTS' HEART PUMP FUNCTION AND COUNTER-MEASURES THROUGH PHYSICAL EXERCISES

采用实验测试方法对１１２６名大学生８项心泵功能指标进行纵向对比，分析大学生心泵功能现状特点、发展趋势及与体育锻炼的关系。研究结果表明：１）目前在校四个年级男大学生心功能各项指标呈持续增长趋势，而高年级女大学生的心功能明显下降；２）入学时来自农村的大学生功能优于来自城市的大学生，而在大学高年级则呈相反趋势；３）将两次测试的心泵功能指标对比发现，入学时心泵功能水平男学生１９９５年比１９９１年要高，但大学四年级毕业时大多数指标１９９５年比１９９１年差；４）大学生心泵功能检测结果大多数指标显示大学生高年级有所下降。

The present study makes a longitudinal comparison based on 8 indices of heart pump function of 1 126 college students.The paper also analyses current characteristics and developmantal tendencies of college students' heart pump function which is relative to physical exercises.Results show that :1)All heat function indices of male college students present a continuous increaes while those of female ones of high. Grades present a significant decrease.2)At the enrolmant,heart function of countryside college students is beeter than that of city ones. But at high grades, the situation is opposite. 3) By the comparison between heart function indices of 1991 and thoes of 1995, we finds that the heart function level of male students at the enrolment is higher in 1995 than that in 1991 while most heart function indices while graduating from the college are lower in 1995 than those in 1991.4)The heart pump function of college students of high grades declines gradully. In the end, the paper puts forward countermeasures through physical exercises.
