<abstract> <p>Heterogeneous networks are complex directed graphs that incorporate multiple types of vertices and edges, enabling the representation of diverse structural and semantic information, and facilitating the abstraction of real-world phenomena. In the context of modern-day societal demands and pressures, individuals seek emotional solace and physical well-being. Notably, China has witnessed a surge in winter sports tourism, with outdoor activities such as skiing gaining increased attention. However, research in this field is sporadic and lacks a comprehensive analysis of the distinctive features of snow and ice sports tourism. Hence, this paper proposes to investigate the demand for ice and snow sports tourism products and its underlying factors using a heterogeneous network model. Drawing upon relevant theories and content, the study analyzes the primary drivers of the development of ice and snow sports tourism. Furthermore, based on the evaluation of ice and snow sports attractions across five major cities, the research synthesizes various product requirements that affect both existing and potential consumers of ice and snow sports tourism. The ultimate aim is to provide practical insights to guide the development and design of ice and snow sports tourism products and ensure the sustainable development of tourism destinations. The final experimental results reveal that the three most crucial aspects of ice and snow sports tourism products are entertainment, stimulation, and safety, with respective effective rates of 64.0%, 62.1%, and 58.9%.</p> </abstract>
Introduction: In a “U” shaped field, the skier must take off using snow slides in a determined territory, using the distribution of his body mass over his feet to control the direction, completing a variety of complex movements inherent to aerial sports. Objective: Study the effect of acceleration on skiers’ skill levels. Methods: Peak moment angle and range of motion were measured in 12 U-shaped cross-country snow ski athletes with an average training period of over 5 years. The isokinetic muscle strength test parameters were analyzed with the characteristics and abilities inherent to the sport. The corresponding range of motion and the angle of acceleration were determined. The results were confronted with a literature search and discussed afterward. results: The peak torque and relative peak torque of the flexor and extensor muscle groups on both sides of the athletes’ hip and knee joints reduced with increasing angular velocity; the maximum peak torque of the extensors was significantly greater than that of the flexors at the same velocity (P﹤0.05). The current scientific literature predicted this inversely proportional relationship, but the angles obtained had not been explored. Conclusion: Athletes should pay attention to improving cognitive ability and active adjustment ability to complete their technical movements, promoting the development of controlled acceleration required by snow sports. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
Teachers play an essential role in physical culture, and they are not only responsible for analysis and guidance but also responsible for formulating specific training methods and training rhythms according to athletes’ personalities. Computer technology has developed rapidly into the 21st century. In sports training, some researchers have also started to analyze and generalize physical activity and movement patterns using IoT technology. Not only can it analyze the rules of specific sports science, but it can also use computers to intentionally infiltrate sports facilities to provide advanced technical support to effectively improve training and science. In this article, IoT technology is introduced to study the auxiliary system for ice and snow sports training. Before designing the system, this paper plans the system architecture in detail, including the principle of stability, the simplicity and practicality, and the principle of low price. Using this auxiliary system, the sensitivity of the lower limbs of ice and snow athletes was trained in this paper. The sensitivity scores of 5 athletes before the experiment were 50, 54, 49, 38, and 35, and the scores after the experiment were 32, 26, 31, 35, and 30, and the sensitivity was significantly improved.
