Predicting a Biomechanical Model Using Neural Networks for the Serving Skill of Iraqi National Volleyball Players
Abstrct
The biomechanical-physiological model, structured according to its variables, involves the collection and analysis of components using advanced technologies. This study utilises cutting-edge equipment, including the Electromyography (EMG) device, which measures muscle electrical activity, and the Biosyn system, which provides data on body height and angular positioning through its integrated sensors. Among the most significant artificial intelligence techniques are artificial neural networks, which serve multiple purposes, including the recognition of individuals, scenarios, speech, images, fingerprints, handwriting, and patterns. Additionally, they facilitate system simulation and predictive modelling of performance. The application of artificial neural networks in learning offers valuable insights for athletes, coaches, and sports specialists, enabling them to assess performance levels, evaluate technical and skill-based execution, obtain results, and generalise findings within the field. Moreover, this model allows for future reference and refinement. This study aimed to develop a model based on artificial neural networks to enhance the analysis of volleyball serving skills, integrating physiological and biomechanical compatibility outcomes. It sought to predict the most critical physiological and biomechanical variables influencing the serve performance of the Iraqi national volleyball team. The research population comprised 18 national team players, from whom a sample of 8 players (44.44% of the total) was selected. Each participant was given 10 attempts in the serve test, resulting in a total of 80 observations. The findings indicate that volleyball players can be categorised in terms of serving skills based on physiological and biomechanical variables.

The advent of cinema brought with it its use as a propaganda device with which to transmit ideals and doctrines. As a result, newsreels and cinema documentaries were born with the aim of showing the «most relevant» news of the country and abroad, the former with a shorter duration. In this study, the Spanish NO-DO and «Sucesos Argentinos» are used as primary sources to interpret the images and imaginaries that were projected between 1943 and 1955 on female physical culture. The intention is to understand the official discourse of both political regimes on what Argentinean and Spanish society should be like, especially by questioning those meanings about women. In total, 69 issues of NO-DO and 14 editions of «Sucesos Argentinos» have been found which aim to show female physical culture in this period. The female physical culture shown in both newsreels was aimed at strengthening women’s bodies so that they could carry out their «natural functions» (mother, wife, housewife), as well as highlighting their «inferiority» in relation to men through lower impact activities and the homogenization of bodies through clothing, and the performance of the same exercises in synchrony. And all this in countries with different regimes, but which, in the end, coincided.
