Abstract
The purpose of this study was to examine the excess postexercise oxygen consumption (EPOC) and peak blood lactate (PBL) response of sprinters to exhaustive treadmill running, maximal isokinetic performance, and free sprinting. Ten university sprinters (age, 24.8 years; height, 178.9 cm; weight 74.9 kg) performed a 2‐minute, individualized anaerobic speed test (AST), a five repetition set on a isokinetic power master ergometer (APM) and 5 and 10 repetition free sprint sets (FS5 and FS10). Protocols consisted of 5‐second maximal repetitions and 10‐second active recovery. Expired gases were analyzed by a Cosmed K2 system during all performances. Results indicated a relationship of r = 0.87 between corrected EPOC and PBL during the four experimental protocols. Tukey's post hoc comparison statistics revealed significant difference (p ≤ 0.05) between both the values of EPOC and PBL for AST (15.16 L, 14.8 mmol · L−1) when compared with the APM (11.38 L, 12.7 mmol· L−1), FS,o (9.88 L, 11.6 mmol L−1), and the FS5 ...
