Inertial measurement units (IMUs) show promise in addressing the prevailing research problems due to their numerous advantages. This study aims to explore the key technical characteristics of the take-off and landing phases in snowboard halfpipe to analyse the key factors that affect the take-off quality and landing stability of athletes at different sport levels.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      The study used an IMU-based motion capture system combined with high-speed video recording (\n                      <jats:italic>via<\/jats:italic>\n                      Xsens and Fastcam Mini WX100 high-speed cameras) to collect kinematic data from halfpipe snowboarders during their movement process.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The elite athletes reached the vertical position at approximately 50% of the normalized take-off phase, compared with approximately 60% in novice athletes. The overall speeds achieved by the elite athletes were greater than those of the novice athletes.
