Abstract

This paper measured the EMGFT of youth soccer players with the methods of determination EMGFT of Matsumoto.Aim to testify the stability of determination of EMGFT with the method non-invasive.To discuss the relationship between EMGFT and LAT,VAT,HRT in increments load,then analyze and evaluate the feasibility of the method of measure AT.Methods:Incremental load test to determine LAT,VAT,HRT;EMG threshold determined experimentally EMGFT.Results:EMGFT were 151.08±10.52W,153.56±12.93W,respectively in the stability of EMGFT trial.There was a highly significant correlation(r=0.95,P<0.001).A paired t-test indicated that there was no statistically significant difference in the two trial(P>0.05).EMGFT,LAT,VAT and HRT during trial were 2481±463 ml/min,2507±501 ml/min,2580±474 ml/min and 2610±517 ml/min as VO2 for parameter,respectively.There were a highly significant correlation between VO2 at EMGFT and VO2 at LAT(r=0.97,P<0.001),VAT(r=0.91,P<0.001),HRT(r=0.76,P<0.05).EMGFT,LAT,VAT and HRT during trial were 157±20W,158±20W,162±21W and 162±26W as watt for parameter,respectively.There was a highly significant correlation between watt at EMGFT and watt at LAT(r=0.96,P<0.001),VAT(r=0.93,P<0.001),HRT(r=0.71,P<0.05).Conclusion:By the use of the method of EMGFT which by Matsumoto invented,it indicates that the method may determinate EMGFT and very efficiency and stabilization.These data suggest that there were a highly significant correlation between VO2 or watt at EMGFT and VO2 or watt at LAT、VAT、HRT,and its order is EMGFT →LAT→VAT.These data indicate the method of determination EMGFT use to the determination of AT.It is a non-invasive simple and easy.The method of HRT was instability,it indicates that HRT not suitable to measure AT.
