improvement in various physical parameters in more recent players compared to those in previous decades (eg, RBs in 2000 had higher scores in bench press, power, and vertical jump by 11%, 9%, and 7.7%, respectively, than those in 1987 43 ). Furthermore, programs display improved strength and power performance

. Planning such types of training during the weeks before the competitive season’s start might also permit to get the most out of it as it has been shown that vertical jump height peaks a few weeks after NMES training in athletes. 9 , 33 Also of importance is the ∼16% lower jump height we found with NMES

A rapid countermovement was conducted by the participants descending until the knee angle reached approximately 90°, followed immediately by a vertical jump. Participants were instructed to jump as high as

Although Tod and colleagues were not concerned with the variability of their kinematic data, the effect of self-talk on the variability
