The physiological factors that relate to 5000 m running performance were studied in 36 male distance runners of three different groups (14 min, 15 min and 16-17 min). Subjects underwent a test to determine the relationships among 5000 m performance (average velocity of 5000 m : V_<5000>), aerobic power, and blood lactate accumulation. The liner relationship was found to exist between V_<5000> and aerobic power (r = 0.562, p < 0.001). Also the relationship was found to exist between V_<5000> and VOBLA (r = 0.867, p < 0.001). VOBLA appeared from 90 to 101% of V_<5000> at any groups and the average of each group was about 96%. To investigate whether this result can be useful for training or not, 12 subjects were performed to run with 90, 92.5 and 95% of V_<5000> by interval training method (5 × 4 minutes running with 90 second recovery). In the 90% of V_<5000> blood lactate was steady with 3.0 mM, and it appeared around 4.0 mM in the 92.5% velocity of V_<5000>. However, in the 95% of V_<5000> blood lactate was above 4.0 mM from initial stage and was gradually increased as the trial was passed. From these results, it was suggested that 92.5% of V_<5000> was optimal velocity to lead to VOBLA.
