The study design was a single-group repeated measures design. Nineteen individuals meeting the inclusion criteria were included. The assessments were conducted individually in a quiet environment, isolated from other athletes and external factors. Athletes were instructed to refrain from intense exercise and training, avoid caffeine consumption, and attend the assessment in sportswear within the last 24 hours. Upon arrival for the assessments, athletes were seated to rest while demographic information was collected. Each test was explained verbally and visually, and participants were allowed to perform a trial. A crossover design method was used in the study, with the order of tests (hands on hips or hands free) determined randomly. Retest measurements were conducted 24 hours after the initial test at the same time of day. The tests performed are described below.

The Y Balance Test (YBT) is a shortened version of the Star Excursion Balance Test. It assesses reach distances in three directions: anterior, posteromedial, and posterolateral

The Reactive Balance Test (RBT) incorporates the YBT setup with an LED light system connected to a smartphone application. For RBT, LED lights were placed at 80% of the participants' maximum reach distance in the anterior, posteromedial, and posterolateral directions of the YBT setup (ReactionX).

While the athlete was in a supine position on a mat, the distance between the ASIS (anterior superior iliac spine) and the medial malleolus was measured on both the right and left sides using a measuring tape. The lower extremity length was used to calculate the YBT composite score
