The purpose of this study was to determine and correlate the neuromuscular and physiological indices with the performance of trained runners in distances of 800 m and 1500 m. Eleven athletes were evaluated in the following tests: 1) simulation of performances in 800 m and 1500 m; 2) determination of maximum oxygen consumption-VO2max; velocity at VO2max-vVO2max and of velocity at onset of blood lactate accumulation; 3) vertical jumps (Counter Movement Jump and Continuous Jump); 4) determination of time to exhaustion-Tlim; and 5) submaximal tests for identification of running economy, followed by a supramaximal test for determination of maximum accumulated oxygen deficit. vVO2max and Tlim were correlated with both distances. The CJ was correlated only to 800m. It is concluded that aerobic power is the main determinant of performance for the two distances, emphasizing that neuromuscular aspects influence the 800 m.
