Running economy (RE) at an intensity above the lactate threshold (LT) is reported to be the most important aerobic capacity for estimating 1,500-m running performance. The reason that the RE at intensity better reflects the energy metabolism during a 1,500-m run, is that it is performed above the LT intensity running. This study clarified the relationship between an 800-m run, which is performed above the LT intensity, and aerobic capacities, including the RE measured at intensities below and above the LT. This study included 12 well-trained male middle-distance runners (800-m velocity: 25.5 ± 0.5 km·h −1 , LT intensity: 79.7 ± 5.1% maximal oxygen uptake [V ・ O2max]). Both the RE of below and above the LT intensity were calculated at 65%V ・ O2max (RE 65 ) and 90%V ・ O2max (RE90). The 800-m velocity was not related to the V ・ O2max or the LT intensity (r = -0.16 and -0.10, respectively). This velocity correlated with both RE90 and RE65, with the correlation coefficient being higher for RE90 (r = -0.80 vs -0.75). Furthermore, the coefficient of determination for the 800-m velocity determined from V ・ O2max, LT intensity and RE90 was higher than that determined from V ・ O2max, LT intensity and RE65(R 2 = 0.522 vs 0.428, P = 0.03 vs 0.06). Based on these results, we concluded that the RE at an intensity above the LT might be better than other aerobic capacities for estimating the 800-m running performance, and more than 50% of this performance can be explained by V ・ O2max, LT intensity and RE at an intensity above the LT.

Running economy (RE), which is evaluated at an exercise intensity below the lactate threshold (LT), is recognized as the most important physiological variable for estimating running performance. However, middle-and long-distance athletes run above LT intensity during their competitive events. This study elucidates the relation between 1,500-m running performance and physiological variables, including RE measured at intensities below and above the LT. The study included 34 male distance runners (1,500-m velocity: 22.2 ± 0.8 km·h −1 , equivalent to race times of 4′03″2 ± 8″5). RE was calculated at four running velocities selected to provide intensities of 90%LT and 95%LT below LT (REbLT) and 105%LT and 110%LT above LT (REaLT). RE was determined from aerobic energy metabolism, calculated from oxygen uptake and the respiratory exchange ratio, combined with anaerobic energy metabolism, calculated from the change in blood lactate concentration. Results show that the 1,500-m velocity was not related to maximal oxygen uptake (V ・ O 2 max) or LT intensity (r = 0.19 and 0.10, respectively). This velocity correlated with both REaLT and REbLT, with the correlation coefficient being higher for REaLT (r = −0.65 and −0.71 vs −0.56 and −0.58). Furthermore, the coefficient of determination for 1,500-m velocity determined from V ・ O 2 max, LT intensity and REaLT was higher than that determined from V ・ O 2 max, LT intensity and REbLT (R 2 = 0.603 and 0.640 vs 0.415 and 0.543). These results suggest that RE measured at an intensity above LT intensity may be better than other physiological variables for estimating 1,500-m running performance.
