July 23, 2015 updated by: Funda DEMIRTURK, Tokat Gaziosmanpasa University

Investigation Of Muscle-Tendon Unit By Ultrasound After Static And Dynamic Stretching

The purpose of this study is to investigate the acute effects of two different types of muscle stretching (static and dynamic) on muscle-tendon unit of gastrocnemius muscle by ultrasound and to follow how long the stretching effects are sustained.

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.

Detailed Description

Muscle stretching is a very common practice applied in warm-up process in order to enhance performance in sports and to prevent or decrease the risk of sports injury. Muscle stretching is also used for therapeutic purposes in many clinical conditions.

It is generally performed in either static or dynamic manner. Muscle is brought to its lengthened position and is held at that point for a certain period of time in static stretching (SS). In dynamic stretching (DS), however, active movements of muscle take the joint through the range of motion and creates a stretch, but the muscle is not held in the end position.

Although recent studies suggest that static stretching has adverse effects on performance, reduces maximal muscle force and is not successful in preventing non-contact injuries, as believed so; and the dynamic type therefore gaining popularity; it is reported that flexibility and range of motion can be improved by stretching as a consequence of the decrement in muscle stiffness. However, the effects of stretching depend on the type, duration and timing of stretching and there is still debate over which prescription provides the best results in terms of flexibility, power, performance or injury protection. And what happens to the viscoelastic properties of a muscle when it is stretched statically or dynamically is still not well documented. Ultrasound seems to be a good option as it offers an objective and a non-invasive way to expose the alteration in muscles and tendons due to stretching.

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

18 years to 30 years (Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.

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
muscle-tendon unit length
Time Frame: before stretching exercises and just after the stretching exercises and 5, 15 and 30 minutes after stretching
change in muscle tendon unit property with static and dynamic exercises will be followed by ultrasound before, right after and 5, 15 and 30 minutes after the stretching exercises
before stretching exercises and just after the stretching exercises and 5, 15 and 30 minutes after stretching
pennation angle
Time Frame: before stretching exercises and just after the stretching exercises and 5, 15 and 30 minutes after stretching
change in pennation angle of the gastrocnemius muscle with static and dynamic exercises will be followed by ultrasound before, right after and 5, 15 and 30 minutes after the stretching exercises

muscle thickness
Time Frame: before stretching exercises and just after the stretching exercises and 5, 15 and 30 minutes after stretching
change in muscle thickness of the gastrocnemius muscle with static and dynamic exercises will be followed by ultrasound before, right after and 5, 15 and 30 minutes after the stretching exercises
before stretching exercises and just after the stretching exercises and 5, 15 and 30 minutes after stretching

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

Time Frame: before stretching exercises and just after the stretching exercises and 5, 15 and 30 minutes after stretching
change in range of ankle dorsiflexion with static and dynamic exercises will be followed by ultrasound before, right after and 5, 15 and 30 minutes after the stretching exercises
