About this study
Official title: The Effects of Progressive Core Stabilization Training on Anaerobic Performance in Elite Athletes: A Randomized Controlled Trial.
The studies in the literature have not sufficiently investigated the effects of core stabilization training on anaerobic performance. Therefore, this study was planned to comparatively investigate effects of progressive core stabilization training applied to elite athletes on anaerobic capacity, anaerobic performance, and fatigue.
Read the detailed description
In taekwondo, weightlifting, badminton, and volleyball sports branches, strong relationships between sports performance, anaerobic strength and fatigue parameters have been also shown. It is clear of the necessity of developing anaerobic capacity using various exercises in these elite athletes. However, the studies conducted to date have not sufficiently investigated the effects of core stabilization training on anaerobic performance and fatigue with more objective methods and enough sample sizes. This study was planned to comparatively investigate effects of progressive core stabilization training applied to elite athletes on anaerobic capacity, anaerobic performance, and fatigue.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Progressive Core Stabilization TrainingOther
The Progressive Core Stabilization Training was applied to study group as a group exercise with 5-10 athletes which was planned in the form of 3 days/week for a total of 9 weeks and 27 sessions. A session consisted of warm-up, core stabilization (30-40 min.), and cool-down exercises. During the training period, exercise volume, degree of difficulty, additional weight, and level of instability (contralateral limb movements and reduction of the support surface, etc.) for each exercise were incrementally increased in four steps.
Standard Core Strengthening ExercisesOther
The athletes included in the CG performed only Standard Core Strengthening Exercises which is the first phase of the Progressive Core Stabilization Training on fixed surfaces (i.e. without pads and balls, with a flat floor and a bench) for 3 days/week and totally 9-week.

Questions about this trial
What is this clinical trial studying?
A study testing Progressive Core Stabilization Training and Standard Core Strengthening Exercises in people with Athlete, run by Gulsah Bargi at 1 site in Turkey (Türkiye).
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 18 Sep 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?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?
anaerobic peak power (time frame: Baseline and after 9-week training). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06042374, which also lists 3 linked publications.
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 18 Sep 2023.
