Acute Study on Muscle Soreness, Damage, and Performance

November 16, 2020 updated by: Pharmanex

A Randomized, Double-blind, Placebo Controlled, Single-center Study to Determine the Effects of Pre-workout and Recovery Formulations on Soreness, Performance, Tolerance and Safety Outcomes in Healthy Adults Undergoing Training Program

The acute study will evaluate pre- and post-exercise ingestion of a multi-ingredient supplement in a randomized, double-blind, placebo-controlled, crossover design. Participants will complete one enrollment visit, in which they will sign a consent form and complete a health history questionnaire. Participants will complete two interventions, with three visits each (6 visits total), in which a treatment beverage (pre/post supplement, or non-caloric placebo) will be consumed within 30 minutes prior to exercise and within 15 minutes post-exercise, in random order. Total time from enrollment to completion will be at least 14 days. Testing visits will be separated by a minimum of 7 days of rest to allow for recovery and washout, based on a half-life of ≤8 hours for all ingredients present in the supplement.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
32

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Performance
Time Frame: baseline, 24 hours, 48 hours
Change from baseline on performance by measuring countermovement vertical jump height using a jump mat and associated velocity using a linear transducer.
baseline, 24 hours, 48 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Muscle soreness
Time Frame: baseline, 24 hours, 48 hours
Change from baseline on muscle soreness using visual analog scale (a horizontal 100 mm line where zero will represent no soreness and one-hundred will represent maximum amount of soreness. Participants will be asked to place a single vertical that represents their current soreness. The scale will be measured with a calibrated ruler with the higher numbers representing more soreness.)
baseline, 24 hours, 48 hours
Creatine Kinase
Time Frame: baseline, 24 hours, 48 hours
Change from baseline on muscle damage by measuring creatine kinase
baseline, 24 hours, 48 hours
