Mechanical and neuromuscular benefits arise during ballistic stretch-shortening cycle muscle activation, yet resistance training regimens are typically non-ballistic, and in contrast to ballistic movement, require a concentric deceleration phase.Twelve healthy males performed a unilateral, six repetition maximum non-ballistic elbow flexion-extension task during; (i) rapid shortening (RS), (ii) stretch-shortening cycle (SSC) and (iii) a 2-s eccentric and 2-s concentric control (C).A load cell and shaft encoder recorded respectively force and velocity. Surface electromyographic root mean square amplitude (EMG RMS ) was recorded in the biceps and triceps brachii, and is reported as the relative (%) difference, normalised to control (C).The average lengthening and shortening velocity of SSC (0.57±0.03ms −1 ; 0.43±0.02ms −1 ) was significantly greater than RS (0.22±0.01ms −1 ; 0.35±0.01ms −1 ), and C (0.17±0.00ms −1 , 0.20±0.00ms −1 ). Peak eccentric force was increased (P<0.0001) and in the first 5% of concentric movement during SSC, in the first and last repetitions respectively (194.7±8.4N, 164.1±7.5N) when compared to RS (163.3±8.9N, 152.4±7.5N) and C (155.9±8.5N, 152.2±8.7N). Eccentric EMG RMS in the biceps brachii was significantly increased during the first three and final repetitions of SSC (31.9±10.9%, 46.7±12.4, 69.3±13.6%, 92.0±16.4%), and the third and last repetitions of RS (35.9±7.4%, 50.3±10.9%), compared to C (0.00%, 15.8±4.0%, 23.7±4.1%, 39.2±8.6%).In the current study, eccentric limb velocity potentiated eccentric and concentric force, concentric velocity, and eccentric EMG amplitude during non-ballistic exercise.
