About this study
Official title: Effects of Dynamic Stretching Exercise Training on Muscle Tendon Unit
The purpose of this study is to investigate the effects of a 5-week dynamic stretching exercise training on muscle-tendon unit of gastrocnemius muscle.
Read the detailed description
Muscle stretching is a common practice applied in warm-up process 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. The effects of stretching depend on the type, duration and timing of stretching. However, the acute and chronic effects of a stretching can be different in the same muscle.
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. Dynamic type is reported to improve flexibility and range of motion better. But there is still debate over which prescription provides the best results in terms of flexibility, power, performance or injury protection. And the answer to the question what happens to the viscoelastic properties of a muscle when it is stretched dynamically for some period of time has not been clearly established.
This study is planned to investigate the effect of a 5-week dynamic stretching exercise training on muscle tendon unit of gastrocnemius muscle. The effects of the training program will be assessed by ultrasound.

|---|---|---|
| dynamic stretching exercise | Experimental | This group will perform dynamic stretching exercise to their left side gastrocnemius muscles for 5 weeks (5 days a week, 3 sets of exercise a day, each set including 5 repetitions of dynamic stretching lasting 45 seconds) Receives: Other: stretching exercise |
| control | No intervention | this group will not perform any stretching exercises for 5 weeks |

The record says: finished, as of the sponsor's last update on 8 Nov 2016. 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 Turkey (Türkiye). 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. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
muscle-tendon unit length (time frame: at the end of 5 weeks of training). The study lists 3 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 8 Nov 2016.
