muscular endurance since during the fight repetitive vigorous isometric actions with short recovery intervals between them are necessary. The measurement of isometric resistance may be more relevant for the evaluation of athletes than the maximum strength measurement. Therefore, in association with more a pronounced blood flow observed at intervals between isometric contractions as an adaptation to training, it is expected that Jiu-Jitsu athletes can benefit from NaHCO 3 supplementation, as this substance may contribute to the delay of fatigue ( Junior et al., 2015

voluntary isometric contraction exercise were reported ( Beretić et al., 2013 ). However, a vertical jump is deemed the movement most related to swimmer’s start performance ( Bishop et al., 2013 ; Zatsiorsky et al., 1979 ). It is well known that CMJ as well as squat jump (SJ) tests correspond to maximum muscle power produced by the knee extensors ( Bosco, 1999 ). Highly trained athletes produce maximum mechanical power output during jump squats using resistance of ~55% of 1RM of full squat strength ( Baker et al., 2001 ). It was also shown that muscle activation of the

A maximum voluntary isometric contraction (MVIC) was recorded for each participant by having them assume their squat stance with a barbell placed across their back and press into stationary pins for five seconds at 75% of their standing height. Design and Procedures All testing occurred in the same session. Participants were randomly assigned to either the belt or back squat for their
