The purpose of this study was to describe an electromyogram (EMG) pattern during a submaximal eccentric task in 7 subjects adapted to high-force chronic eccentric exercise and 6 subjects naive to eccentric exercise. The EMG in all subjects was quantified during identical submaximal (200 W) eccentric and concentric cycle ergometry tasks. The EMG of the eccentrically adapted subjects was decreased (p < 0.05) compared to the eccentrically naive subjects, in duration, amplitude, and intensity as evidenced by a decreased EMG during the pedal cycle. This decrease may be one component of the protective effect that results from progressively increasing repeated bouts of eccentric muscle work. Clients and patients transitioning to rigorous overload training should become adapted to high eccentric loads and forces to avoid injury and a potential delay in their strength and conditioning training regimens.
