The Effect of Posture and Scapular Position on Performance Parameters in E-sport Players

The research aims to examine how shoulder proprioception, scapular position, physical activity levels and posture influence key performance factors such as visual reaction time, audiotory reaction time and hand-eye coordination. Various digital tools and tests will be utilized for assessment, including reaction time tests and hand-eye coordination evaluations conducted through HumanBenchmark and Audioreactiontime websites respectively, as well as posture analysis via mobile applications. Shoulder proprioception will be measured at specific flexion angles using a smartphone-based inclinometer, while scapular dyskinesis will be assessed through the lateral scapular sliding test. Additionally, participants' physical activity levels, assessed via the International Physical Activity Questionnaire (IPAQ), will be analyzed to determine potential correlations.
