About this study
The aim of this study is to investigate the effects of exercises performed with stroboscopic glasses-recently gaining popularity in sports-on cognitive function, physical performance, and postural stability, which are among the key skills in athletic performance.
The originality of the study lies in being the first to examine the effects of stroboscopic glasses-based exercises on basketball players.

Control groupOther
Also called Exercise training under normal visual conditions
Active Comparator: Control group The exercise program to be implemented within the scope of the study is the SHRed (Sports Injury Prevention for the Lower Extremity, focusing on musculoskeletal and head-related injuries) neuromuscular training program. The program will be administered over six weeks, with two sessions per week.
The control group will perform the exercises under normal visual conditions. The exercise program to be implemented within the scope of the study is the SHRed (Sports Injury Prevention for the Lower Extremity, focusing on musculoskeletal and head-related injuries) neuromuscular training program. The program will be administered over six weeks, with two sessions per week. Previous research has shown that the SHRed injury prevention neuromuscular training program reduces ankle and knee injuries in youth basketball players by 36% [35]. The program consists of balance, agility, strength, and aerobic exercises.

What is being measured
The primary outcome is the main question the study is designed to answer.
Cognitive function
It is planned to conduct the assessment using the Central Nervous System Vital Signs test battery. The Central Nervous System Vital Signs is a computer-based neurocognitive test battery with established validity and reliability, and is utilized in 66 countries.
Measured: Day 1, after the 6 weeks and after the 4 weeks
Secondary outcomes (5)
Static Postural stability
Postural stability will be assessed statically using the GYKO inertial sensor. The GYKO inertial sensor system (dimensions: 50 × 70 × 20 mm, weight: 35 g; Microgate, Bolzano, Italy) includes a three-dimensional accelerometer, gyroscope, and magnetometer, enabling data acquisition at a sampling frequency of 500 Hz (full-scale range: 8 g).
Measured: Day 1, after the 6 weeks and after the 4 weeks
Dynamic Postural stability
Dynamic postural stability will be assessed using the Lower Extremity Y Balance Test, which is employed to evaluate dynamic balance, mobility, and neuromuscular control.
Measured: Day 1, after the 6 weeks and after the 4 weeks
Change of direction ability
In the assessment of physical performance, change of direction ability, reactive agility, and jumping performance will be evaluated. The change-of-direction (COD) ability will be assessed using the V-Cut Test. The V-Cut Test is a valid and reliable COD assessment for young basketball players (ICC = 0.92) [26].
In this test, athletes perform a 25-meter sprint incorporating a 45° change of direction every 5 meters. The total completion time of the test is recorded.
Measured: Day 1, after the 6 weeks and after the 4 weeks
Reactive agility
In the assessment of physical performance, change of direction ability, reactive agility, and jumping performance will be evaluated. Reactive agility assess Y shaped test. The Y-Shaped Agility Test will be administered to evaluate reactive agility performance. This test is specifically designed to represent the change-of-direction movements and running patterns frequently encountered in basketball [29]. The protocol consists of a 5-meter straight sprint followed by a 45° change of direction to either the left or right side, followed by another 5-meter sprint. Athletes begin from a stationary position 30 cm behind the starting line, and timing is initiated once the first photocell gate is crossed. After completing the initial 5-meter sprint, the athlete changes direction to the predetermined side (left or right) and sprints an additional 5 meters. The timing is stopped when the athlete passes through the second photocell gate.
Measured: Day 1, after the 6 weeks and after the 4 weeks
Jumping Performance
In the assessment of physical performance, change of direction ability, reactive agility, and jumping performance will be evaluated. Jump performance will be assessed using the My Jump Lab application.
Athletes will perform one familiarization trial at submaximal effort, followed by a 1-minute rest period, and then complete three vertical jumps.
The validity and reliability of the My Jump Lab application have been previously demonstrated.
Measured: Day 1, after the 6 weeks and after the 4 weeks
