The sport of snowboarding has grown in popularity as both a recreational winter activity as well as a prominent Olympic sport. Both forms are comprised of one of three different disciplines within the sport: freestyle, alpine, and snowboard-cross. In recent years, the increased professionalism and substantial growth of snowboarding as a global sport has increasingly attracted the interest of exercise physiologists and sport scientists. Given the small (but growing) number of studies that have been published, the research analyzing the physiological and performance characteristics and requirements of snowboarding remains limited. The absence of such studies signifies a lack of examination into this important but under-explored area of research, which could contribute valuable information to the scientific community and international snowboarding teams. The studies conducted thus far have indicated different requirements of physiological and physical traits dependent upon the specific discipline of snowboarding in question. For example, in order to meet the divers demands of each discipline, athletes must develop various qualities, such as muscular strength and power. This can increase their ability to withstand the high forces and loads on the muscular system during competition, and further decrease their risk of lower limbs injuries. At the same time, the studies acknowledge the potential advantages of aerobic fitness in terms of recovery, to more efficiently sustain the athlete through both competitive and on- and off-snow training sessions. Given the value and breadth of application of these limited studies, further analysis and research could contribute greater knowledge and benefits to the field of snowboarding. Therefore, it is the purpose of this preliminary review to explore the current literature, providing further insight into the physiological and physical demands of snowboarding performance. This preliminary review is intended to stimulate interest among the communities of exercise physiologists, sport scientists and particularly coaches in order to improve our current understanding of snowboarding and its demands as a sport. This preliminary review further seeks to develop protocols and strategies to assess physiological and performance characteristics of snowboarding, monitor athletic performance, provide practical recommendations for training, identify new areas of scientific research, and develop accurate talent identification programs.

A muscle strength asymmetry between FL and RL was detected only in elite SBalp. This asymmetry is lower than the ±15% cutoff interval used to define clinically relevant bilateral strength asymmetry and is likely to be explained by technical aspects. Indeed, only SBalp athletes naturally distributed the center of mass, and thus, the weight toward RL to have a good board control. This feature likely reflects a greater adaptation of the muscle characteristics.

Vernillo, G, Pisoni, C, Sconfienza, LM, Thiébat, G, and Longo, S. Changes in muscle architecture of vastus lateralis muscle after an alpine snowboarding race. J Strength Cond Res 31(1): 254-259, 2017-This study aimed to assess acute changes of vastus lateralis (VL) muscle architecture after an alpine snowboarding simulated race and to compare architecture characteristics between the front and rear legs on elite alpine snowboarders. Using ultrasonography, VL muscle thickness (MT), pennation angles (θ), and fascicle lengths (Lf) were assessed in 8 elite alpine snowboarders (25.6 ± 4.4 years; stature: 178.4 ± 9.8 cm; body mass: 78.1 ± 12.1 kg) before and directly after an alpine snowboarding simulated race under competition rules. Muscle thickness, θ, and Lf showed no meaningful changes (P > 0.05, differences reported as trivial) after the race for both legs. The rear leg tended to have a 14.0% lower θ (P = 0.04, differences rated as moderate) and a 13.6% higher Lf (P = 0.04, differences rated as moderate) compared with the front leg. Changes in muscle architecture are not observable immediately after an alpine snowboarding simulated race. The ∼14.0% difference in muscle architecture between the front and the rear leg suggests the presence of a morphological asymmetry in elite alpine snowboarders with direct implications for injury prevention and training prescription.
