Exploration of Internal and External Factors of Swimmers’ Performance Based on Biofluid Mechanics and Computer Simulation

Abstract

The purpose of this study is to explore the influence of different swimming strokes on the performance of swimmers and the resistance of each part from the perspective of hydrodynamics. In this paper, the influence of internal and external factors on the swimming speed is analyzed comprehensively and meticulously from the macro and micro perspectives. In the macroscopic part, the swimming speed representation model is established, and the validity of the model is further verified by the analysis of experimental data and hydrodynamic equations. In the microscopic part, we carefully analyzed details such as the opening angle of the palm, the timing of the arm and leg and the angular velocity of each link of the human body. Combined with computer simulation, stereo modeling and numerical analysis are carried out, and the best scheme FOR how to cooperate with each part of the body in swimming is given.

Exploration of Regional Public Digital Culture Service Mode Based on Artificial Intelligence Technology

“…Liu and others' representative views on the integration of public digital cultural resources mainly include pointing out that public cultural institutions should carry out service activities according to the needs of users, provide users with a resource environment covering various knowledge fields, and effectively attract new users through joint construction and sharing among institutions [13]; Wang proposed that search engines should arrange and combine public digital cultural resources according to users' retrieval information to provide resources and services that best meet users' needs [14]. Santiago pointed out in cloud storage research that cloud storage has surpassed physical media to become a dominant means of communication and a way to share digital content, and its advantages in music, documents, photos, and videos are more obvious [15].…”

Estrategias de calentamiento y rendimiento contrarreloj en nadadores. Revisión rápida de la literatura (Warm-up strategies and time trial performance in swimmers. Rapid review of the literature)

“…Una de las formas de medir el rendimiento es a través de la rapidez de nado, la cual, está determinada por la eficiencia mecánica (por ejemplo, longitud y frecuencia de brazada, y resistencia al avance, entre otros) (Liu et al, 2021). Cualquier aumento de la rapidez requiere un incremento proporcional de fuerza muscular, el desarrollo de potencia y la capacidad/eficiencia de los sistemas de suministro energético para mantenerla (Vorontsov, 2011).…”

Intelligent Planning and Research on Urban Traffic Congestion

“…The intelligent traffic system (ITS), also known as the Intelligent transportation system, includes the advanced fields of science and technology (information technology [32], computer technology [33], data communication technology [34], sensor technology [35], electronic control technology [36], automatic control theory [37], computer simulation [38],Artificial Intelligence [30], etc.) that are effectively integrated into transportation [39], service control, and vehicle manufacturing, in order to strengthen the relationship between vehicles, roads, and users, thus forming a comprehensive transportation system that plays a large and all-round role.…”
