Sensor-based cloud computing data system and long distance running fatigue assessment.
Wireless sensor networks are widely used in sports training, medical and health care, smart home, environmental monitoring, cloud data and other fields because of their large scale, self-organization, reliability, dynamic, integration and data centralization. Based on this point, this article conducts a comprehensive analysis and research on cloud computing data systems, and designs and implements a dynamic replication strategy. Since different users have different demands for different data at different times, it is necessary to record and analyze recent users' data access, so as to actively adjust the number and location of data blocks. ⋯ This study will design a simulated specialized exercise load experiment to reproduce the load characteristics of excellent athletes during mid to long distance running, in order to induce exercise fatigue in the main muscles of different parts of their bodies. At the same time, the amplitude frequency joint analysis of the surface changes of EMG signal in this process is carried out. This article conducts research on sensor based cloud computing data systems and long-distance running fatigue assessment, promoting the development of cloud computing data systems and improving long-distance running fatigue assessment methods.

Real-time monitoring for sport and mental health prevention of college student based on wireless sensor network.
This article uses wireless sensor network technology to freely combine multiple sensor nodes to achieve, but the scale and capacity of WSN internal nodes are limited, so it is easier to encounter a series of network attacks and security threats. When setting the access protocol, the protocol needs to identify the precautions for malicious attacks against the network, and at the same time try to achieve a balance between network weights to improve the life cycle of the network. This paper presents a multi-station basis for a wireless sensor connection system. ⋯ We have analyzed the system demand information of college students' sport and mental health, and analyzed the problems that the system needs to solve in detail. Through in-depth analysis of the sport and mental health information system, using wireless sensor network technology, we conducts a thorough investigation of the needs of the student sport and mental health system. Then we conduct an in-depth analysis of the system structure, architecture design, business model, available system, database system, to make the system more acceptable to people.

Socioeconomic inequities and barriers to physical activity in Argentina.
Physical activity (PA) is recognized as a protective factor for health. Despite the importance that has been given to health differences in recent decades, strong inequities still persist. This article examines the inequities in the levels and barriers to PA in Argentina. ⋯ The main barrier to PA was lack of time (37.3%), followed by health reasons (24.3%) and lack of will (15.4%). Females, individuals who were married or in a couple relationship, those with incomplete secondary education, those who belonged to the three low-income quintiles, and people over 65 years old were 34% (OR 0.66 95% CI 0.59-0.65), 17% (OR 0.83 95% CI 0.79-0.88), 41% (OR 0.59 95% CI 0.56-0.62), 36% (OR 0.74 95% CI 0.70-0.78), and 51% (OR 0.49 95% CI 0.45-0.53) less likely to comply with WHO guidelines, respectively. To plan public policies to promote PA, it is necessary to consider inequities related to physical inactivity, while understanding the PA patterns according to social determinants.

Application of multi-target positioning algorithm in basketball teaching system and injury prevention.
In today's era, the rapid spread of information and the rise of major network platforms provide good conditions for online learning and at the same time provide a new development idea for basketball teaching. The establishment of modern multimedia teaching theory provides theoretical support for the research and development of this subject. Construct and apply the online learning system of basketball basic technology, provide high-quality education, and can accommodate a large number of basketball fans to study and exchange together, and improve the physical fitness of young people. ⋯ The KLBSA-LoT algorithm accurately locates the anchor point and uses a cooperative mechanism to predict the position information of unknown nodes in basketball. Applying this algorithm to basketball teaching can greatly improve the accuracy of its positioning training. Sports teaching provides new methods.

The preventive effect of PNF stretching exercise on sports injuries in physical education based on IoT data monitoring.
In physical education, in order to prevent sports injuries of students, it is necessary to study and build a set of physical education Internet of Things data monitoring training system to prevent sports injuries of students. This system is mainly composed of sensors, smart phones and cloud servers. ⋯ By analyzing students' sports data and health data, the system generates personalized training programs, including training intensity, training time, training frequency and other parameters, so as to meet the needs and actual conditions of different students and avoid sports injuries caused by overtraining. This system can better analyze and process the collected data, provide teachers with more comprehensive and in-depth assessment and monitoring of students' sports status, and provide students with more personalized and scientific training programs, so as to effectively prevent the occurrence of students' sports injuries.
