About this study

Official title: Sodium Bicarbonate Supplementation Promotes Changes in Performance, Muscle Activity and Strength of Individuals Trained During the Performance of Intermittent and Intense Task? Randomized, Double-blind, Crossover Trial

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sodium bicarbonateDietary supplement

    The subjects should ingest 0.3g.kg of sodium bicarbonate 90 minutes before the beginning of the protocol task.

  • Calcium carbonateDietary supplement

    The subjects should receive gelatinous capsules containing 0.3 g.kg -1 of Calcium Carbonate

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Electromyographic activity of the femoral quadriceps evaluated with electromyography equipment

    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.

    Measured: 60 minutes

  2. Peak torque assessed with isokinetic dynamometer equipment

    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.

    Measured: 60 minutes

Secondary outcomes (1)
  1. Lactate assessed with portable lactometer

    The lactate quantification will be performed before and after the test session characterized by 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 an interval of 1 minute between sets in an isokinetic dynamometer.

    Measured: 15 seconds

Questions about this trial

What is this clinical trial studying?

A study testing Sodium bicarbonate and Calcium carbonate in people with Sodium Bicarbonate and Alkalosis, Metabolic, run by University of Nove de Julho at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 17 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Marcelo M Kalytczak, PhD (55 11 981595139, marcelomkal@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Electromyographic activity of the femoral quadriceps evaluated with electromyography equipment (time frame: 60 minutes). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Oct 2019.
