Objective biomechanical indicators: assessing symmetry of knee joint angle changes in barbell squat exercise for athlete technical efficiency

Abstract

The indicators of symmetry in angle changes within the knee joints during the execution of the barbell squat exercise serve as objective biomechanical metrics for assessing an athlete's technical proficiency. These indicators play a critical role in evaluating the athlete's movement patterns and biomechanical alignment during the squat exercise, offering valuable insights into their technical proficiency and areas for potential improvement. Through the analysis of knee joint angle symmetry, coaches and sports scientists can assess the quality of the athlete's movements, detect any asymmetries or imbalances, and customize training programs to optimize technical efficiency and mitigate injury risks. The primary goal of our research is to investigate the indicators of symmetry of the angle changes in the knee joints during the performance of the barbell squat exercise as a valid method for assessing the indicators of technique effectiveness.
