usefulness as a vertical-jump performance metric. Although RSImod was shown to be related to force and power characteristics of the unloaded CMJ, such as rate of force development ( r  = .56–.66), peak force ( r  = .37–.50), and peak power ( r  = .47–.69), 4 that study only included “gross” measures of CMJ

young male soccer players (aged 16 y), reporting better improvements in vertical jumping performance in LPJT group (Δ9.4% and 8.4% for squat jump [SJ] and CMJ, respectively, in LPJT group; Δ4.6% and 5% for the SJ and CMJ in UPJT group, respectively). Recently, Coratella et al 14 studied the effects of

separated by 40 min or undertook vertical jumps and a 400-m sprint. Each of these sessions was undertaken twice. The body mass reductions averaged 0.8 and 1.3 kg in the 50/200-m sessions over a 2-hr period, and averaged 0.5 and 1.1 kg over 45 min in the 400 m and vertical jump session. These reductions are

-Sensor 2; BTS Bioengineering, Brooklyn, NY). As described previously, participants started the movement standing upright with hands on their hips, and after a verbal cue, descended into a squat (countermovement) prior to performing a maximal effort vertical jump. Participants performed 3 maximal efforts

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

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

., 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
