The Impact of FIFA 11+ on Isokinetic Muscle Strength and Balance

Study Overview
=================
Brief Summary
-----------------
FIFA 11+ program; It consists of simple, easily remembered, and time-consuming, sport-specific exercises underlying fair play. Although the FIFA 11+ program is a well-established warm-up protocol for injury prevention among football players, the performance improvement aspect of the program is not often discussed in the literature. The study's objective is to investigate the efficacy of the FIFA 11+ program on sports performance parameters such as dynamic balance, isokinetic muscle strength performance in adolescent amateur male football players.

Detailed Description
-----------------
This study was planned in a randomized controlled experimental type. The footballers of a team from an amateur league will be included in the research. All participants will be tested at baseline and 9 weeks after baseline. The participants will be submitted to the following testing procedures: dynamic balance (Star Excursion Balance Test), muscle strength assessment (Isokinetic assessment). After the baseline measurements will be completed, the control group members will be advised to continue their regular warm-up program. This program consists of jogging and stretching exercises. The experimental group will complete the FIFA 11+ training, which consisted of six different types of running exercises; six exercises with three levels of increasing difficulty to improve the participants' strength, agility, core stability, eccentric control, etc.; and advanced running exercises, such as running across the pitch, bounding, planting, cutting. The FIFA 11+ will be applied to the experimental group 3 times a week for 9 weeks. The control group's warm-up duration will be matched to the experimental group's duration (20-25 min). This routine workout will perform 3 times a week for 9 weeks. At the end of 9 weeks, the evaluations will be repeated (Star Excursion Balance Test, Isokinetic assessment).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Isokinetic assessment | When assessing the football players in terms of strengths, frequently use isokinetic systems . Computer aided muscle-testing dynamometers are utilized for measuring muscle force and this provides us with an assessment of muscles and group of muscle in an isokinetic manner. Isokinetic muscle testing is conducted with a stable speed of angular motion yet variable resistance. | Baseline |

| balance assessment | Dynamic postural control will be measured with the Star Excursion Balance Test (SEBT), which will be applied with a system of 8 lines. The foot will be placed in the center of the testing system to be bisected equally in the medial-lateral anteroposterior planes. SEBT is made up of 8 directions: anterior, anterolateral, lateral, posterolateral, posterior, posteromedial, medial, and anteromedial. | Baseline |
