The physiological factors that relate to marathon running performance were studied in 24 marathoners of three different categories (Elite Runners, Good Runners and Slow Runners). Oxygen uptake at average marathon speed (AMS) was significantly correlated (r = 0.93) to performance in the marathoners. This showed a significant difference in the three categories. Also, this data indicate that marathon performance of sub 2: 30 (ER) and sub 3 : 00 (GR) need respectively above 54 ml/kg/min and 45 ml/kg/min during the race. It was suggested that these differences at AMS were dependent on the difference VO_2/kg at 2.5 mM and 3.0 mM (r^2 = 82〜84%) in three categories. The two factors that contribute to VO_2/kg at 2.5 mM and 3.0 mM are: VO_2 max/kg (r = 0.83〜0.88) and average weekly distance (r = 0.64〜0.66). VO2/kg at fixed blood lactate concentration of 2.5 mM, 3.0 mM and 4.0 mM were significantly correlated to AMS (r=0.80〜0.82). There were no differences in the three categories in delta speed and V0_2/kg while increasing from 2.5 mM to 4.0 mM, which means the aerobic-anaerobic transition. The delta values were 20.8〜24.6 m/min in speed and 4.7〜5.6 ml/kg/min in V0_2. From these results, it is indicated that marathon running performance correlates closely to V0_2/ kg at AMS and velocity and V0_2/kg at fixed blood lactate concentration of 2.5 mM, 3.0 mM and 4.0 mM, which shows a significant difference in ER, GR and SR.
