The Relationship Between Upper Extremity Explosive Power and Trunk Muscles in Volleyball Players
An observational study of Ultrasonography and Upper Extremity, run by Hacettepe University at 1 site in Turkey (Türkiye).
Trial summary
Volleyball is an interval sport involving consecutive aerobic and anaerobic loads. Strength training based on explosive movements can improve performance in the upper extremities. Strength performance has an important place in this sport. Trunk stabilization is defined as 'proximal stability for distal mobility'. Read more about this study

About this study
Official title: Voleybolcularda Üst Ekstremite Patlayıcı Güç Ile Gövde Kaslarının Arasındaki İlişkinin İncelenmesi
Volleyball is an interval sport involving consecutive aerobic and anaerobic loads. Strength training based on explosive movements can improve performance in the upper extremities. Strength performance has an important place in this sport. Trunk stabilization is defined as 'proximal stability for distal mobility'. Disorder in any segment of the kinetic chain model will affect the quality of movement in the lower and upper segments.The aim of this study is to examine the relationship between the morphological features of the transversus abdominis, lumbal multifidus (L4-5), internal external oblique muscles, and the anaerobic power of the upper extremity and shoulder girdle functionThis study was designed as a cross-sectional. They will consist of 30 volleyball players between 14-30 years of age. Muscle morphological features of the participants by ultrasound; explosive strength will be evaluated by Medicine Ball Throw test, functional evaluation will be evaluated by Closed Kinetic Chain Upper Extremity Endurance test.

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 13 Oct 2023. 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?

Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Aynur Demirel (+90 305 157 6168, aynur.demirel@hacettepe.edu.tr), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle morphology (time frame: 1 day). 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 13 Oct 2023.
