Brief Summary

Multitasking (Dual Task) is a measurement method to evaluate cognitive ability to execute multiple functions at the same time. To perform this test, while participant/patient performing a main skill (for example, walking), a cognitive skill is added (for example, counting 7 backwards from 100) to measure how much the completion performance of the activity is affected. Frequently used multitasking trainings are known as counting back from 100 and asking mathematical equations during a physical skill. Multitasking skill is rarely used in sports-related training, and it is generally used in the form of counting 7 backwards from 100, counting months and counting 5-letter words while walking over obstacles. However, multitasking training methods described and applied in the literature are not specific to football skills. For this reason, limited tests defined and applied in other clinical and sportive fields may not be sufficient in football players who perform activities that require high performance. Therefore, aim of this study is to develop a dual-task assessment method, which includes the cognitive loads experienced by football players during training and matches, and also covers the basic skills of football. As a result of this study, a football-specific dual-task test will be created and the capacity of the athletes will be measured by applying this test to healthy athletes. Also, this test will be conducted on football players with recent knee injury history, who wish to return to sport, and to evaluate their dual-task capacity and to correlate it with kinesiophobia and other performance tests

Primary Outcome Measures

Name	Time	Method
Traditional dual task assessment	At the baseline	Players will dribble with the ball with and without cognitive task. As cognitive task, players would be asked to count down from 100, by 7.

Secondary Outcome Measures

Name	Time	Method
Juggling tests	At the baseline	Player will juggle the ball with both feet as much as he can, until the count of 25. Best of right and left foot will be recorded. For the second trial, player will juggle the ball in all of the following orders: chest-foot-head, head-left foot-right foot or foot-chest-head. Each correct trial scores as 1 point and total of 9 points can be taken.
Fast dribbling test	At the baseline	Player would dribble through an obstacle course as much as they can and the total time is recorded.
Long pass accuracy test	At the baseline	Player will be asked to long pass the ball in to a 2m-radius circle within a 10m by 10m square from 36 meters distance. 3 points is scored if ball falls within the circle and 1 points is scored if the ball falls within the square. Total of 5 repetitions is recorded.
Stroop test	At the baseline	There will be color names appearing on the computer screen written in different color (for example: word "yellow" written in blue) and player is asked to pick the name of the color. total time to correctly pick 10 names is measured and recorded.
Return to sport readiness	At the baseline	ACL-RSI (Anterior Cruciate Ligament - Return to Sports after Injury: the survey consists of 12 items that are graded on a visual analogue scale from 0 points (extremely negative psychological responses) to 100 points (no negative psychological responses). The results of the survey have been found to be strongly and significantly associated with return to sport.) scoring will be applied.
Simple and choice based reaction times	At the baseline	For simple reaction time, player is asked to press space bar as soon as he sees the x appeared on the box on the screen.; For choice based reaction times, there will be four boxes on the screen and player is asked to press the button (z, x, b and n buttons) related to the box in which the "x" symbol appeared.
Mental rotation task	At the baseline	there will be 3 shapes on the screen with one at the top and two at the bottom. One of the shapes on the bottom is the rotated version of the one at the top. The player will be asked to find the right one, as quickly as possible. Total number of right answers will be recorded.
Kinesiophobia measurement	At the baseline	Tampa scale of kinesiophobia (scale range from 17- 68, where 17 means no kinesiophobia, 68 means severe kinesiophobia, and score ± 37 indicates there is kinesiophobia.) and Fear of avoidance questionnaires (he questionnaire consists of 16 items in which a patient rates their agreement with each statement on a 7-point Likert scale. Where 0= completely disagree, 6=completely agree. There is a maximum score of 96. A higher score indicates more strongly held fear avoidance beliefs.) will be conducted.
Corsi task	At the baseline	From the 9 balls appearing on the screen, three of them will blink in random order. Player will be asked to click on them in the same order of blinking. For each correct trial, the number of blinking balls will increase until all of the balls are blinking. total number of right order will be recorded.
