Ski Jumping Kinematic Determination of the Aerial Phase

Hazel Scarlett

Finding a general approach to identify the airborne phase of ski jumping during which the athlete is in a constant gliding condition, often known as the "stable flying" phase, was the goal of this study. Instead of focusing on the athlete's actions, the physical point mass of the aerial portion of ski jumping was examined. In four distinct hill sizes, a thorough data collection using a Differential Global Navigation Satellite System (dGNSS) was conducted. 19 competitors with performance levels ranging from junior to world cup performed a total of 93 leaps, which were all measured.

We suggest a general technique based on our analysis that determines the stable flying based on steady independent of hill size and athlete performance level, glide aerodynamic circumstances.

The state known as stable gliding occurs when the Lift-To-Drag ratio (LD ratio) changes at a pace that falls within a small bandwidth that is denoted by a threshold. Regardless of the magnitude of the slope or the research's performance level, was equal to 0.01 s-1 for this study employing dGNSS. We contend that the methodology and algorithm suggested determining the beginning and end of a steady glide (stable flight) could be used in future studies as a general definition and help clarify the communication of results as well as enable more accurate comparisons between studies. The absolute value may change when measured with other sensors, but we believe that this is unlikely to affect the significance of the results.
