Core Stabilization Training in Elite Athletes

Study Overview
=================
Brief Summary
-----------------
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.

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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Study group<br>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. | Other: Progressive Core Stabilization Training<br>* 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.<br>|
| Sham Comparator: Control group<br>The athletes included in the CG performed only Standard Core Strengthening Exercises. | Other: Standard Core Strengthening Exercises<br>* 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.<br>|

| anaerobic mean power | The power will be evaluated using anaerobic endurance test (a 30-second Wingate Anaerobic Power Test) applied on a bicycle ergometer. | Baseline and after 9-week training | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| squat jump power | It will be evaluated the squat jump test. | Baseline and after 9-week training | 
| active jump power | It will be evaluated the active jump test. | Baseline and after 9-week training | 
| fatigue index | The percent of fatigue will be evaluated using anaerobic endurance test (a 30-second Wingate Anaerobic Power Test) applied on a bicycle ergometer. | Baseline and after 9-week training |
