| 摘 要： | 通过10名体育专业健康男性大学生在Jacger程控跑台上分别进行有累进递增负荷与无累进递增负荷，并在实验中测定各档跑速时的相应心率(HR)和血乳酸值(NLa)。结果无累进递增负荷的AT值明显推迟出现；进一步研究发现采用无累进递增负荷测定的AT值更能科学地反映机体的实际水平，能对评价运动员有氧耐力水平和指导运动训练提供更科学的依据。

| Abstract: | By making ten health male athletic majors run on the programme-controlled jacger running platform with a progressive increasing load and with an unprogressive increasing load respectively,we have detemined the corresponding HR and HLa of the runners at various speeds.As a result,the apearance of AT in running with an unprogressive increasing load is abviously later than that in running with a progressive increasing load.Further analysis shows that the AT determined in the method of unprogressive increasing load is a more scientfic reflection of the real level of the body and gives a more scientific basis for estimating an athlet's aerobic endurance and for guiding sports training. |
