Skeletal coordinate data of various body parts were obtained from 12 university students as they threw darts using two stance types: the open stance and the closed stance. We then compared the relationship between throwing form and scoring performance.<br><br>Although the preferred stance varied among individuals, the closed stance resulted in higher scores overall. Additionally, high-scoring participants exhibited consistent arm positioning at the moment of release, maintaining an appropriate distance between the arm and torso throughout the throw. In contrast, lower-scoring participants tended to show greater variability in their release position, leading to unstable dart trajectories.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"602\" height=\"267\" src=\"https:\/\/www.comm.tcu.ac.jp\/masuda-lab\/wordpress\/wp-content\/uploads\/2025\/12\/image-1.png\" alt=\"\" class=\"wp-image-1904\" srcset=\"https:\/\/www.comm.tcu.ac.jp\/masuda-lab\/wordpress\/wp-content\/uploads\/2025\/12\/image-1.png 602w, https:\/\/www.comm.tcu.ac.jp\/masuda-lab\/wordpress\/wp-content\/uploads\/2025\/12\/image-1-300x133.png 300w\" sizes=\"auto, (max-width: 602px) 100vw, 602px\" \/><figcaption class=\"wp-element-caption\">Table 1.
