Effect of Eight Weeks of 11+ Training on Functional Movement Screening Test Scores in Female Futsal Players

Extended Abstract


Introduction
ollowing the encouragement of the general public in a community to increase participation in sports activities, unfortunately, the number of people at risk of injury has increased [1]. One of the important priorities of the society is to have healthy and energetic youth and capable and efficient human resources, F which can lead to productivity and reduction of medical expenses and frequent absences from work [2]. Epidemiological studies have shown that one sixth of all injuries observed by physicians occur during sports activities and the rate of injuries has increased following an increase in participation in sports activities [3], where the lower limbs including knee and ankle joints have had the most injuries [4]. Screening is performed to prevent injury as well as to improve implementation strategies [8].
Functional Movement Screen (FMS) method includes seven movement tests that have the ability to identify limitations and changes in normal movement patterns. These tests are designed to interact between postural chain mobility and the stability required to perform functional and essential movements [9]. One of the core stability trainings is the 11+ exercise program, which include strength exercises and core stability exercises suitable for muscle strength and dynamic and static balance at three levels, which have recently been considered by FIFA [12]. The aim of this study was to investigate the effect of an 8-week 11+ exercise program on the FMS scores in female futsal players.

Methods
This is a quasi-experimental study. Study population consists of all female futsal players in Isfahan, Iran. Of these, 48 were selected using a convenience sampling method and assigned into two groups of exercise and control. First, a demographic form was completed by the subjects, which includes personal information such as height, weight, age, playing history, activity per week, and history of injury or illness. After obtaining written consent, all subjects meeting entry criteria (no history of injury or surgery in the past 6 months) were evaluated by FMS tests before and after intervention. In order to evaluate the scores of FMS, a special kit consisting of a FMS board with 56 inch (calibrated 43 inch) length, 6 inch width, and 2 inch height; graded long rod with a length of 48 inches, two short rods with a length of 25 inches, an elastic band, and data collection forms were used [7]. The FMS tests included: Deep Squat, hurdle step, in-line lunge, active straight-leg raise, trunk stability push-up, quadruped rotary stability, and shoulder mobility. The protocol of 11+ exercise program had three parts according to the guidelines of FIFA Medical Assessment and Research Center.

Conclusion
The 11+ exercise program can improve the scores of deep squat, hurdle step, and in-line lunge tests in FMS method in female futsal players, and can affect their overall FMS scores. It can be used as a modality by coaches, corrective exercise specialists, and physical education teachers to reduce and prevent sports injuries in female futsal players. It can identify poor movement patterns and improve performance.
