November 21, 2020 updated by: HAhmed, Cairo University

Effect of Different Pre Application Time Intervals of Light Emitting Diode Therapy on Muscle

The purpose of this study is to determine the optimal time interval between light emitting diode application and exercise to improve fatigue resistance.The results of this study could be useful in planning a rehabilitation program in musculature disorders and also in athletic training.

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.

Detailed Description

  1. To determine the effect of light emitting diode applied 5 minutes before exercise on pain, rate of perceived exertion and maximum voluntary contraction.
  2. To determine the effect of light emitting diode applied 1 hour before exercise on pain, rate of perceived exertion and maximum voluntary contraction.
  3. To determine the effect of light emitting diode applied 5 hours before exercise on pain, rate of perceived exertion and maximum voluntary contraction.
  4. To determine the difference between light emitting diode applied 5 minutes,1 hour or 5 hours before exercise on pain, rate of perceived exertion and maximum voluntary contraction.

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.
