Alpine skiing: How sensitive is race time to body weight?

Abstract

Alpine skiing, with its blend of speed, technique, and physical endurance, is a sport where every detail counts. Among these details, the weight of the skier plays a pivotal role in determining performance outcomes. Pravin's research [16] emphasized the significance of body mass in enhancing alpine skiing performance. Utilizing a 2D computational model, he embarked on a case study that hinted at the potential for reduced significantly race times with a modest increase in body mass. However, inherent limitations, such as the simplistic nature of the model and the absence of empirical measurement data, underscored the need for further investigation.

Building upon the work of Pravin [16], our recent investigation aims to delve deeper into the dynamics of skiing by examining the impact of air frictional forces and drag on speed and race times across different weight categories. Furthermore, we seek to explore how variations in weight affect the forces acting on the skier, the power required to navigate turns effectively, and how an increased mass will affect the strength requirements of a skier in a turn. By scrutinizing these factors, we aim to provide a useful understanding of the intricate relationship between body mass and skiing performance, offering useful insights for athletes, coaches, and sports scientists.

Therefore, the present proposal endeavors to propel this research forward by refining the computational model into the 3D framework. Additionally, to broaden the research scope, additional case studies and utilization of real-world measurement data were conducted through interaction with Robert Reid, who does research for the Norwegian Ski Federation. By incorporating these insights, the research aims to provide a comprehensive understanding of how body mass affects skiing performance, offering useful insights for athletes and coaches.
