“…The principal topic in Snowboard research is "Sport injuries", which contains data about all snowboard modalities, including Slopestyle (2,3). The biomechanical approach about characteristics of snowboard related with human movement models, is a relevant topic in the literature (1,(4)(5)(6)(7). Sociological and Psychological research is another frequent study field (8)(9)(10).…”

Background. Despite the increasing popularity of the snowboard, there is not scientific literature for sport performance indicators in this sport. Objectives. To analyze the effects of jump difficulty on the final performance during snowboarding-slopestyle competition. Methods. All competition sequences (n=214) from the 2014 Winter Olympic Games were analyzed. Of these, 123 were from the men´s competition and 91 were from the women´s competition. The interaction between the final score and number of rotations was calculated using regression models with quadratic or linear equations. All analyses were performed separately for women and men. Results. Quadratic regression had better R 2 and mean absolute errors than linear regression. Linear and quadratic regressions showed that the number of rotations significantly predicts final score in men. However, in the women´s competition, the curve of quadratic regression was almost identical to that from the linear regression. Conclusion. These results have identified the importance of evaluating the jump difficulty versus its efficacy. Athletes and coaches have to weigh pros and cons of increasing the difficulty of jumps or improve jumps that are already fluent in order to master them.

In this paper, an energy pumping mechanism for locomotion is analysed. The pumping is accomplished by exerting forces perpendicular to the direction of motion. The paper attempts to demonstrate an interesting application of the classical mechanics to two sporting events: a person skating in a half pipe and a person travelling on a level surface on a skateboard. The equations of motion based on simplified mechanical models are derived using the Lagrange mechanics. The energy-pumping phenomenon is revealed through numerical simulations with simple pumping actions. The result presented in this paper can be used as an interesting class project in undergraduate mechanics or physics courses. It also motivates potential new applications of energy pumping in many engineering fields.

“…The static and dynamic responses of snowboards are covered by Brooks 2 and Buffington et al, 12 where data are given for a number of static and dynamic tests. The static tests consist of bending and torsional investigations for a number of restraint conditions.…”

“…Results were presented for the first two or three natural frequencies and mode shapes in both bending and torsion. Buffington et al 12 examined eight snowboards and found the first bending mode to be 2.0-3.0 Hz with a damping ratio between 0.04 and 0.07 and the first torsional mode was at about 12.0 Hz with a damping ratio of 0.015.…”

In this work, a model of a rider and snowboard is presented. The snowboard is modelled as two rigid one-dimensional sections connected by a frictionless pin-joint linked by a torsional stiffness and the rider by a mass at a fixed height above the snowboard, which can move longitudinally. The model is simplified to allow the fundamental behaviour of the snowboard and rider to be investigated for a number of manoeuvres used by learners. The behaviour of the rider is shown to be related to the angle of lean and it is conjectured that the rider might attempt to achieve consistency of response by moving their centre of mass longitudinally. The response of the model in open-loop is difficult to control, and to overcome this, two control loops are designed for the lateral velocity and yaw angle of the snowboard. The model is shown to recreate a number of manoeuvres that are used to help people to learn to ride snowboards.
