The purpose of this study was to identify the variability threshold determined by different parameters and the Conconi Threshold (HRDP) in a 20 m Shuttle Run Test, describing the
concordance between these aerobic indexes. The subjects consisted of professional soccer players. The 20 m shuttle run test was used.The criteria for determining the heart rate variability threshold (HRVT) were the breaking of linearity SD1; breaking of linearity in SD1/SD2; first stage in the curve decrease in which the difference between the SD1 in two consecutive stages is less than 1 ms; breaking of linearity HFpeak x HFms². The HRDP was determined by the breaking of linearity in the heart rate curve. All criteria of HRVT demonstrated a moderately significant correlation with HRDP (r=0.73). However, only the HRVTSD1 presented concordance with HRDP (bias=0.24 km·h-1,P=0.245).The main finding of this study was the demonstration of association between the non-invasive determination of anaerobic threshold in a field test as well as the evidence of agreement between the method HRVTSD1 with the HRDP in soccer players.
