To Whom It May Concern, Below is an abstract of my poster presentation, and please find the pdf of my poster attached. Thank you! *Kinematics Comparison of Squat (2D versus 3D analysis) for Asynchronous Laboratory – A Pilot Project* (Mia) Mianxin Huang and Leia B. Bagesteiro Bodyweight squats are a common exercise in athletic training and rehabilitation due to their biomechanical and neuromuscular similarities to fundamental movements in a variety of sports and their requirement of major joints and numerous muscle groups coordination. (Schoenfeld, 2010). Therefore, it is essential that kinesiology students, whose future careers often include athletic training and rehabilitation, learn how to analyze the kinematics of a squat. While three-dimensional (3D) movement analysis is considered the gold standard for motion capture (Chung, 2012), two-dimensional (2D) digital video analysis is more commonly chosen in education environments to provide hands-on experience. Some studies have investigated the differences between 2D and 3D analysis of squats (Escamilla et al., 2001; Krause et al., 2015; Schmitz et al., 2015). This study aims to compare 2D and 3D measurements of narrow-stance squat while enhancing learning by engaging students with hands-on experience using free, open-source software. Nine healthy 18 to 54-year-olds (6 females, 3 males) participated in this pilot project. Following proper COVID safety guidelines, 2D analysis was performed by undergraduate students at home while 3D analysis was performed in the gait laboratory at San Francisco State University. Statistical significance was found when comparing the differences between 2D and 3D measurements, except for hip flexion. The resulting angular and linear measurements from both 2D and 3D analyses aligned with previous research, suggesting that 2D digital video analysis is a feasible option for educational purposes despite the statistically significant differences. Stay safe, stay sane.
