focus on strategies that might have an application within jumps and be of interest for future research. Hypohydration Acute hypohydration can impact muscle strength, power, and endurance to varying degrees, as well as vertical jump ability ( Savoie et al., 2015 ). According to a recent meta

. 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

in “real-world” settings, with the best of performance (jump height) used for further analysis. 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

.g., Landin & Hebert, 1999 ) and two studies reported changes made to the vertical jumping kinematics of their relatively unskilled participants (e.g., Tod et al., 2009 ). Although Tod and colleagues were not concerned with the variability of their kinematic data, the effect of self-talk on the variability

., Ltd., Niigata, Japan). Subjects stood on the circular rubber mat (38-cm diameter) with the jumper line attached at the waists. Subject jumped vertically with maximal effort against the resistance of the jumper line and landed on the rubber mat. Vertical jump height was calculated with a traveling
