Resumen: Currently, people pay more and more attention to their own health condition, and have shifted from the traditional passive participation in sports to the active participation, which brings the national sports boom is more and more intense. In this paper, we believe that the landscape design of sports scenes should take into account the needs of the public's life and the development trend of changing from landscape form to focus on the harmonious relationship between the human body and the environment, and try to put forward the form of sports landscape in the field of landscape design of sports scenes, and combined with the personalizedfeedback technology to design an ideal sports landscape design programwith a high degree of perception to do a preliminary investigation. This requires designers to provide personalizedfeedback services, so this paper introduces user interest subclasses, analyses the user's historical behavioraloperations, obtains the user's rating value on the interest subclasses, and then calculates the user's interest distribution based on the rating value. Based on the idea of user interest subclasses, considering the local similarity of users, we spread the traditional collaborative filtering algorithm to different interest subclasses for the prediction of overall similarity calculation and rating. Then we combine the calculation results with the user's interest distribution to obtain the final recommendation list of the user. Based onthe personalizedfeedback technology in the sports scene landscape design provides a new perspective and way of thinking, and we hope that the sports scene landscape can bring people a pleasant sports experience, but also can call on more people to strengthen the importance of sports and fitness (AU)

Resumen: Basketball games, real-time adjustment of defense strategy according to the changes on the court can greatly improve the team's chance of success in defense and thus win the game. The development of artificial intelligence technology, especially computer vision, provides a technical basis for real-time tracking of players' positions and body postures. In this paper, a player posture estimation algorithm based on local spatial constraints is proposed based on motion tracking technology and deep learning technology. The algorithm is based on the general human body pose estimation algorithm, which locally constrains the picture based on the athlete detection frame, retains only the content related to the athlete in the picture, and then inputs the processed picture into the general human body pose estimation model for pose detection, and finally maps the detected pose back to the original picture to complete the estimation of the athlete's pose. The model is verified to be able to efficiently complete the real-time defensive strategy optimization task by using NBA game videos for testing (AU)

Título: Physical activity and its correlation with academic performance in south american schools
Fuente: Rev. int. med. cienc. act. fis. deporte;24(94):498-514, jan. 2024. tab, graf.
Idioma: en.
Resumen: This study examines the connection between academic achievement in South American schools and physical exercise. Even while research from throughout the world indicates that regular physical exercise and academic achievement are positively correlated, it is critical to investigate this relationship in the context of South American educational systems, taking social, cultural, and regional differences into account. Using a mixed-methods approach, the study combines qualitative observations from educators, students, and parents withquantitative analysis of academic achievement data and physical activity levels. Data is gathered from various South American schools that include urban and rural environments, a range of socioeconomic origins, and a variety of educational frameworks.Initial results show that physical activity and academic achievement are positively correlated in South American schools. Regular physical exercise among students is associated with enhanced cognitive performance, decreased stress levels, and improved generalwellbeing. The influence of social contact and extracurricular physical activities on academic performance is also considered in this study. However, the study recognizesthat a more complex comprehension of the South American setting is necessary. Cultural norms, geographic differences, and distinctive characteristics of educational programscan all impact the association's kind and degree. The study emphasizeshow crucial it is to modify interventions and instructional techniques to fit South American classrooms' unique requirements and dynamics. As a result, the study adds to the expanding corpus of research on the connection between academic achievement and physical exercise, providing information that will help shape educational practices and policiesthroughout South America (AU)

Título: Effects of psychological stress and anxiety on performance and coping strategies in athletes
Fuente: Rev. int. med. cienc. act. fis. deporte;24(94):482-497, jan. 2024. ilus, tab.
Idioma: en.
Resumen: Competitive sports are social sports activities with the main goal of winning competitions, which require athletes' physical and psychological abilities to be extremely high. Therefore, paying attention to the psychological health of outstanding athletes and improving their comprehensive quality are crucial to improving their sports performance. Traditional measures of psychological stress and anxiety mainly measure subjective stress feelings through stress perception scales, which ignores objective physiological indicators, while electroencephalogram (EEG), as an objective physiological data, has a strong correlation with different psycho-physiological conditions. Traditional feature extraction algorithms combined with machine learning require a large amount of a priori knowledge, while deep learning does not require a priori knowledge to deeply mine the deep features of the data. Therefore, this paper identifies and analyses psychological stress and anxiety in athletes based on deeplearning by combining physiological data obtained from EEG signals and subjective data obtained from stress perception scales. Specifically, a stress EEG signal recognition model based on Transformer is proposed, the Transformer model in deep learning is explored, the encoder module in the Transformer model is applied to EEG signal analysis, and adaptive improvements are made and parameter optimization is carried out to be suitable for EEG signal analysis. Then experiments were carried out on two EEG signal public datasets, and the simulation experiment results proved the effectiveness of the proposed method (AU)

Resumen: Football tactical training is of great significance to the improvement of football level and the development of football, while the tactical training system is rich in content and diversified in structure, how to coordinate the content of tactical trainingsystem has become a key topic to improve the effectiveness of tactical training. In this paper, we design the method of tactical training for college football teams, aiming at building a tactical optimisation and opponent analysis model based on big data mining and machine learning from the reality of tactical training for college high-level football teams. Specifically, the convolutional neural network with two levels of cascade detection and regression in the model adopts the classic ideas of face key point detection and human body key point detection: the idea of cascade regression is used for the detection of the key point location from coarse to fine; the heat map of the key point obtained from the first level network is used as the supplemental information, and the original map is used for the feature fusion; the Heatmap, which has better effect, is used as the Ground Truth of the network; the Heatmap is used as the ground truth of the network; the Heatmap, which has better effect, is used as the ground truth of the network. The second stage regression network uses Heatmap as the Ground Truth of the network, which provides pixel-by-pixel supervision for the regression of the key points' positions and the prediction of whether the key pointsare visible ornot. In addition, this paper combines the idea of adversarial learning to design the loss function to solve the fuzzy problem of regression-to-the-mean when regressing Heatmap. The second-stage network is used as the generator, and the discriminator is designed to define the loss function to judge the reliability of the generated Heatmap (AU)
