The purpose of this study was to evaluate the time course strength and power recovery after a single bout training designed with fast slow contraction velocities. Nineteen male subjects were randomly divided into 2 groups: slow-velocity (SV) group velocity (FV) group. Resistance protocols consisted 5 sets 12 repetition maximum (5 × 12RM) 50 seconds rest between minutes exercises. Contraction controlled by execution for each (SV-6 complete concentric eccentric phases FV-1.5 seconds). Leg Press 45° 1RM (LP 1RM), horizontal countermovement jump (HCMJ), right thigh circumference (TC) accessed in 6 distinct moments: base (1 week before exercise), 0 (immediately exercises), 24, 48, 72, 96 hours exercise protocol. SV FV presented significant LP decrements at 0, these still evident 24-48 postexercise. magnitude decline significantly (p < 0.05) higher FV. HCMJ but only 24-72 TC increments postexercise it continued up hours. increase In conclusion, protocol resulted greater decreases performance, when compared velocity. results lead us interpret that variable may exert direct influence on acute muscle generation capacity.
