The purpose of this study was to examine the accuracy of heart rate as a new method to determine anaerobic threshold. Anaerobic threshold determined by heart rate(HR) was compared with those determined by lactate(LT) or ventilation variables(VT) in laboratory and field tests. The subjects of 16 long distance rurmers whose average age, height and weight were 18.9±1.39years, 172.7 ± 4.76cm and 65.7 ± 4.97kg respectively were examined to determine their LT, VT in laboratory test and HRDP in 5km · 10km field test. The following results were obtained. Oxygen consumption at LT, VT and HRDP lab test were 70.1 ± 5.00 ml/kg/min(88.8 of VO₂max), 68.3 ± 4.5m1/kg/min(86.3% of VO₂max), 72.9 ± 4.6m1/kg/min(89.3% of VO₂max). There were no differences among the results. Heart rate at LT, VT and HRDP in lab test were 178.7 ± 5.00bpm, 171.1 ± 6.95bpm and 180.3 ± 4.94bpm respectively. There were no differences among the results. VO₂ at HRDP in lab test showed high correlation at with VO₂ at LT and VT in lab test(r--0.66 r=0.64 respectively. p$lt;0.05). HRHRDP in field test showed high correlation with HR at HRDP in lab test(r=0.87, p$lt;0.01). Running time at HRDP in field test showed high correlation with, mathematical prediction time and actual running time of 5km, 10km(r=0.88 r=0.82 respectively, p$lt;0.001, p$lt;0.01). The results suggested that the HRDP was a useful method to determine AT of athletes in the field.
