中长跑运动对体内离子浓度变化结果分析

通过对大学生中、长跑前后体内K+ 、Na+ 、Ca+三种离子浓度变化的分析 ,找到了大学生中长跑运动前后体内离子变化的一般规律 。

By analyzing the change of ion density of k +、Na + and Ca + in the body of college students, the general law of ion's change has been discovered before and after the middle-long run, it offers us the guiding theory for the future teaching and training.
