BACKGROUND Compared with visual torque-onset-detection (TOD), threshold-based TOD produces onset bias, which increases with lower torques or rates of torque development (RTD). PURPOSE To compare the effects of differential TOD-bias on common contractile parameters in two torque-disparate groups. METHODS Fifteen boys and 12 men performed maximal, explosive, isometric knee-extensions. Torque and EMG were recorded for each contraction. Best contractions were selected by peak torque (MVC) and… CONTINUE READING
