Purpose: To identify the effect of allometric scaling on the relationship between running efficiency ( R-Eff) and middle- distance-running performance according to performance level. Methods: Thirteen male recreational middle- distance runners ( mean SD age 33.3 +/- 8.4 y, body mass 76.4 +/- 8.6 kg, maximal oxygen uptake [ VO2max] 52.8 +/- 4.6 mL kg- 1 min- 1; G1) and 13 male high- level middle- distance runners ( age 25.5 4.2 y, body mass 62.8 2.7 kg, VO2max 70.4 +/- 1.9 mL . kg- 1 . min- 1; G2) performed a continuous incremental test to volitional exhaustion to determine VO2max and a 6- min submaximal running test at 70% of VO2max to assess REff. Results: Significant correlation between REff and performance were found for both groups; however, the strongest correlations were observed in recreational runners, especially when using the allometric exponent ( respectively for G1, nonallometric vs allometric scaling: r =.80 vs r =.86; and for G2, nonallometric vs allometric scaling: r =.55 vs r =.50). Conclusion: These results indicate that an allometric normalization may improve endurance- performance prediction from REff values in recreational, but not in elite, runners.
