A comparative study of using professional cameras and smartphone cameras in analyzing some biomechanical variables in freestyle swimming

Abstract

The research addresses the importance of using professional cameras and smartphone cameras in analyzing performance in freestyle swimming. The research objective revolves around comparing the effectiveness of these two types of cameras in analyzing some biomechanical variables of freestyle swimming, aiding in understanding the impact of each type of camera on the accuracy of analysis and research results. The main problem highlighted is the scarcity of evaluative studies comparing professional cameras and smartphone cameras in analyzing swimmers' performance, leading to a lack of precise understanding of the technology's impact on swimming training development. The research relies on a descriptive methodology, utilizing a questionnaire as a data collection tool. Additionally, the research identifies a set of biomechanical variables analyzed using the cameras. Results indicate that professional cameras outperform in the accuracy of analyzing certain biomechanical variables in both close and distant shots, provided suitable lenses are used. As for motion capture, results significantly converge, provided motion stabilization mode is activated in smartphones. Smartphone cameras excel at analyzing variables underwater. The research emphasizes the importance of continuing research to evaluate the use of cameras in other sports and raising awareness among coaches and athletes about effectively using available tools to enhance athletic performance.
