N/A Functional ankle instability. Intervention 1: In the experimental group, athletes have performed Wii Fit Plus games including balance training games (e.g. Soccer heading, Ski slalom, Tight rope walk, Table tilt), and strengthening exercises (e.g. Single leg extension, Sideways leg lift, Single leg twist, Rowing squat). In balance training games the athlete stands on the Wii balance board and maintains his balance by shifting his weight during the games. In strengthening games, the athlete stands on the board, and in each game during the specific movements, he must limit the gravity point movements to earn more points. Intervention 2: In the control group, athletes have performed conventional exercises including plantar flexion, dorsiflexion, inversion, and eversion movements with Thera-Band and exercising with the balance board. Training with Thera-Band is performed in three sets with ten repetitions for each movement and is performed in the first, second, third, and fourth weeks, with red, green, blue, and black, respectively. To determine Thera-Band resistance during the ankle movements, 70% of leg length is considered as Thera-Band length, for each athlete. The athletes stand on the balance board and move the front edge against the floor then move the board back, in the first week. During exercise, the board should not touch the floor. In the second week, they move the left and right edges against the floor, and in the last two weeks, circular movements are performed. (they continue the movement for 15 seconds; rest for 10 seconds; repeat this trend 10 times).
