Currently, there are about 200 ski resorts in Russia from Smolensk to Chukotka, which are located both in the low mountains (GC "Tyagacheva", "Sarochany", etc.), and in the middle mountains ("Abzakovo", "Bannoe Lake", etc. ) and highlands (regions of the Elbrus region, Dombay, Krasnaya Polyana, etc.). More than six million Russians go downhill skiing and snowboarding every year. Over the years, the quality of sports equipment and track equipment has changed significantly, which has led to an increase in speeds, an increase in injuries and a change in teaching methods. Currently, a large number of people die and are seriously injured at ski resorts every year due to the low quality of training in safe skiing, lack of control over the work of instructors, and the irresponsible attitude of the holders of ski resorts to the safety of providing services on the ski slopes.

Abstract Aim: To explore the experiences of alpine skiing at the elite level after anterior cruciate ligament (ACL) injury and reconstruction. Design: A qualitative approach where semi-structured interviews were conducted, and an analysis of the manifest content was performed. Participants: Five ski high school students, two male and three female skiers, who had suffered ACL injuries and undergone ACL reconstructions. Results: Seven categories were identified. The participants described their perceived opportunities with regard to returning to alpine skiing after ACL injury and reconstruction as something positive to do with self-belief, being mentally and physically prepared, regaining confidence in their own ability, being given time and using active strategies. In contrast, perceived barriers to a return to elite alpine skiing gave rise to negative feelings, for example, fear, disheartenment, a total lack of or ambivalent confidence in their own ability and the use of passive strategies. Conclusion: The two male skiers returned to alpine skiing. They reported confidence in their own ability, active strategies and support on all levels, as well as enhanced physical ability. The female skiers did not return to their pre-injury level of competitive alpine skiing. They stated a lack of support on all levels, deterioration in their physical ability and two out of three reported passive strategies and no or ambivalent confidence in their own ability. The most important factors were family support, support on all levels, access to a physiotherapist and time given.

AbstractSide-slipping (or skidding) is a feature of several manoeuvres in alpine skiing, including a few types of skiing turns. On hard snow, side-slipping involves removal of a thin top layer of snow, that makes it similar to machining of materials in manufacturing. In this paper, we briefly review the theory of machining and then propose an approximate model that can be used to describe side-slipping in skiing. We test this model against published results of laboratory experiments in machining of ice and snow and find agreement.

Background The anterior cruciate ligament has been shown to be particularly susceptible to injury during alpine skiing. Tibial torque is an important injury mechanism, especially when applied to a fully extended or fully flexed knee. Purpose We wanted to record the forces generated in the anterior cruciate ligament with application of tibial torque to cadaveric knees in different positions. Study Design Controlled laboratory study. Methods Thirty-seven fresh-frozen cadaveric knees were instrumented with a tibial load cell that measured resultant force in the anterior cruciate ligament while internal and external tibial torques were applied to the tibia at full extension, 90° of flexion, full flexion, and forced hyperflexion. Results At each knee flexion position, mean force generated by 10 N·m of internal tibial torque was significantly higher than the mean generated by 10 N·m of external tibial torque. Mean forces generated by tibial torque at 90° of flexion were relatively low. During flexion-extension without tibial torque applied mean forces were highest (193 N) when the knee was hyperflexed. Conclusions Application of internal tibial torque to a fully extended or fully flexed knee represents the most dangerous loading condition for injury from twisting falls during skiing. Clinical Relevance Understanding of the mechanisms of falls can be used to design better equipment and to better prevent or treat injury.
