In the literature neuromuscular exercise programs are often used for prevention in sport players. Literature lacks of perturbation exercises and its effects on peroneal's muscle strength, fatigue and individual's performance parameters. This study will investigate if it is possible to achieve improvements on peroneal eccentric strength, fatigue, dynamic balance and individual's performance with the exercises mainly based on side perturbations.
Chronic ankle instability is very common in adolescent female basketball players. In the literature neuromuscular exercise programs are often used for prevention in sport players that usually contains of strength and/or balance exercises. Perturbation exercises are oftenly used in sport players for returning the sport or prevention but literature lacks of its effects statistically. This study will investigate if it is possible to achieve improvements on peroneal eccentric strength, fatigue, dynamic balance and individual's performance with the exercises mainly based on side perturbations. Strength and fatigue evaluations will be made with Cybex dynanometer. Dynamic balance evaluations will be made with Y-Balance Tests. Individual's performance parameter evaluations will be made with vertical jump test, cross jump test and side hop test.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Neuromuscular Training+Basketball training | Experimental | After all participiants are evaluated, they will be divided randomly to two groups, which one group will be taking neuromuscular training+usual basketball training |
|
| Control group(Basketball training) | No Intervention | After all participiants are evaluated, they will be divided randomly to two groups, which one group will be taking just the usual basketball training and not any extra interventions. |

| Neuromuscular training | Other | Neuromuscular training is designed as 8 weeks and 2 times a week, and approximately 20 minutes per session for Neuromuscular training+usual basketball training group. Other group is only going to keep attending usual basketball training. Neuromuscular training consisted 3 exercises: First exercise is passing the ball to side to side on bosu with standing on one leg. 60-90 seconds on time, 30-60 seconds off time. 2 sets for both passing sides and bilaterally. Second exercise is standing on bosu unilaterally and while standing stabilized, switching basketball hand to hand as dribbling on the floor. Exercise will be on for 60-90 seconds and off for 30-60 seconds, 2 sets for each side Third exercise is jumping with one stance/leg, and landing with double stance while a therabant is attached to the belly and pulling with a minimum/medium force from one side. Changing legs after one jump, 6 times for both side is equal to 1 set of the exercise. It will be done 2 sets for both sides. |
| Measure | Description | Time Frame |
|---|---|---|
| Changes in Peroneal eccentric strength | Force will be evaluated with Cybex Humac NORM, as Nm/kg(Newton-meters/kg). At 30° /s speed, 3 trials will be made with submaximal force for participants to understand the movement. After trials 4 maximal strength repetition will be made. Highest repetition, and average of 4 repetition will be used for analysis. Before and after the intervention evaluation will be made. | 10 weeks |
| Changes in Peroneal endurance parameters | Endurance will be evaluated with Cybex Humac NORM, as Nm/kg(Newton-meters/kg). At 180° /s speed, 5 trials will be made with submaximal force for participants to understand the movement. After trials 20 maximal strength repetition will be made. Endurance is described as containing strength for a duration of time, it can be evaluted with Fatigue index/Endurance parameters will be evaluated with comparing last 10 repetion to first 10 repetion to assess the difference. Before and after the intervention evaluation will be made. | 10 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Changes in Dynamic Balance | It will be evaluated with Y Balance test to anterior, posteromedial, posterolateral sides. The distance will be recorded with cm's. Before and after the intervention evaluation will be made. | 10 weeks |
| Changes in Cross Hop Test |

After first evaluation groups are randomly assigned to 2 groups. Both groups keep attending basketball trainings. One group is just going to keep attending basketball trainings, one group is going to keep attending usual basketball trainings and going to receive neuromuscular training that will be added in warming up exercises

It will be evaluated through cross jumping 3 times on a 6 meter-line. The distance will be recorded wtih cm's. Before and after the intervention evaluation will be made. |
| 10 weeks |
| Changes in Vertical Jump Test | It will be evaluated with Takei Jumpmeter. The height of the jump will be recorded with Takei Jumpmetre with cm's. Before and after the intervention evaluation will be made. | 10 weeks |
| Changes in Side Hop Test | 2 lines with 30 cm distance will be placed. Players will complete 10 jumping from side to side without stepping on the lines. Unsuccessfull jumps will be excluded. The time will be recorded with chronometer. Before and after the intervention evaluation will be made. | 10 weeks |
