摘要
本研究采用先进的ＳＴＩ（心脏收缩时间间期）测试系统及经典的乳酸测量方法，对３０名体育系男生在递增负荷运动时的ＳＴＩ值及血乳酸值做了测定及分析。首次发现用ＳＴＩ指标中的ＬＶＥＴ、ＰＥＰ／ＬＶＥＴ、Ｑ－Ｕ／ＬＶＥＴ、ＭＳＴ、ＥＭＬ等指标推测的无氧阈与乳酸无氧阈之间具有高度相关性（ｒ＝０．９３２５）．并把用ＳＴＩ指标推测的无氧阈命名为＂ＳＴＩ无氧阈＂。该测量方法结果可靠，重复性高，且简便无创。因此具有广阔的应用前景。
The result of this study showes that it is very high correlativity between Anaerobic Threshold (AT) from Hl and STI indexes(firstly named STI AT by us ).STI AT method is especially suitable for making beater-range AT examination because of its characteristics of simple use, easy repetition and accurate results.
