N2 - The aim of this study was to examine whether measurement of peak anaerobic power (Wpeak) by force-velocity test using the arms or the legs influenced the performance obtained when the opposite muscle group was tested. Ten trained male throwers (age: 20.6±2; stature: 1.82±0.06 m; and body mass: 85.5 ± 17.2 kg) performed, on separate days, 2 Monark cycleergometer protocols comprising (a) arm cranking (A1) followed by a leg cycling (L2) force-velocity test (series A-L) and (b) a leg cycling (L1) followed by an arm cranking (A2) force-velocity test (series L-A). On each day, 8 minutes of seated rest separated the 2 force-velocity tests. Arterialized capillary blood was collected from the finger tips for blood lactate analysis at rest and at the end of each force-velocity test. Wpeak-A1 and W peak-A2 were similar (8.1 ± 1.7 and 8.6 ± 1.5 W·kg-1, respectively). Wpeak-L1 and W peak-L2 were 14.0 ± 3 and 13.4 ± 2.8 W·kg -1 (NS). Blood [La] increased significantly after each force-velocity test (p < 0.001), but peak blood [La] did not differ significantly between L1 (6.6 ± 1.2) and L2 (6.2 ± 1.4 mmol·L-1) or between A1 (7.2 ± 1.0) and A2 (7.4 ± 1.6 mmol·L -1). In this population, force-velocity tests performed using the legs or the arms did not induce a significant decrease in force-velocity determinations of peak anaerobic power performed subsequently with the opposite muscle group. In strength-trained athletes, the force-velocity approach can thus be used to measure the peak power output of both the legs and the arms in a single laboratory session, without adversely affecting estimates of an athlete's performance.
