The purpose of this study was to identify an optimal load for the knee extension exercise done with Impulse (Newnan, GA). Forty-one women and twenty-nine men made six laboratory visits, including two familiarization sessions of the knee extension exercise and four real workout sessions which entailed four 30-second exercise sets, separated by 120-second rests, against four different loads (0Kg, 3.41Kg, 5.68Kg, 7.95Kg). A Latin Squares design was used to counterbalance the sequence of the sets. Average force (AF), peak force (PF), total work (TW), Impulse value, and the number of knee extension repetitions were each analyzed with a 2 (gender) x 4 (load) ANOVA, with repeated measures for load. Alpha = 0.05 denoted statistical significance. Tukey test or Tukey-Kramer approach served as post-hoc analysis. Results showed AF, PF, TW, and Impulse value rose with increasing loads. A load of 7.95Kg was the optimal load which collectively had the highest AF, PF, TW, and Impulse value.
