简要总结
The aim of this study was to verify if sodium bicarbonate (NaHCO3) suplementation promotes changes in the performance, muscular activity and strength of individuals trained during the intermittent and intense task . Twelve trained adult men will participate in this randomized, double-blind, crossover clinical trial. Each participant should receive two types of intervention with a 14-day interval between conditions: alkalosis (ALK) in which gelatinous capsules containing 0.3 g.kg -1 of NaHCO 3 and placebo (PLA) are administered, in which 0.3 g.kg-1 of Calcium Carbonate (CaCO3). The following results will be considered: electromyographic activity (EMG) of the quadriceps muscle, peak torque, pH, lactate, and perception of effort, recovery and pain questionnaires, which will be collected during intermittent and high intensity DI protocol. ANOVA of repeated measures will be used to verify possible differences between groups.

结局指标
主要结局
Electromyographic activity of the femoral quadriceps evaluated with electromyography equipment
时间窗: 60 minutes
The electromyographic activity will be obtained during the execution of 10 series composed of ten repetitions of extension (concentric phase) and flexion (eccentric phase) of the knee joint, at an angular velocity of 120os-1 (radians per second), with interval of 1 minute interval between sets in an isokinetic dynamometer.
Peak torque assessed with isokinetic dynamometer equipment
时间窗: 60 minutes
The peak torque will be obtained during the execution of 10 series composed of ten repetitions of extension (concentric phase) and flexion (eccentric phase) of the knee joint, at an angular velocity of 120os-1 (radians per second), with interval of 1 minute interval between sets.
次要结局
- Lactate assessed with portable lactometer(15 seconds)
