台阶试验质疑

Inquiry on Sidestep Test

台阶试验是一项由BROHA建立的用以评价机体对强体力负荷的适应能力和身体机能的恢复能力的运动负荷试验,研究表明:台阶试验指数与运动耐力和最大耗氧量之间无高度相关,因此,不能对心血管系统功能作出准确评价;台阶试验指数只能够对受试者的状况作出好与不好的评价,而不能作出精确评价;台阶试验指数不能有效反映以最大耗氧量、最大心输出量为代表的心脏功能增龄性变化规律及其性别差异。鉴于以上原因,台阶试验作为心血管系统功能评价的运动负荷试验尚待进一步研究。

Sidestep is developed by BROHA.The purpose is to estimate the capacity of body to adjust and recover from maximal exercise load.The result shows that the sidestep index is not highly correlated with maximal oxygen uptake,thus cannot give a very precise estimate of cardiovascular fitness.Secondly,sidestep index can only make evaluation on good or poor condition for subjects,cannot give a accurate evaluation.Thirdly,sidestep index cannot reflect the age and gender related changing of maximal oxygen uptake and cardiac output.Based on above situation,much more research should be made before sidestep test become a valuable measurement of cardiovascular fitness.
