Self-efficacy and healthy lifestyle behaviors as mediators between COVID-19 care knowledge and health status.

The COVID-19 epidemic has affected the psychological well-being and daily life of college students, leading to a decrease in their quality of life. Health status can be influenced by a variety of factors. This study aims to assess the current health status of university students and explore the relationships among COVID-19 care knowledge, self-efficacy, healthy lifestyle behaviors, and health status and how these factors are influenced.

"Do I need to reinvent myself?" Stigmatization of sport-related identities of Chinese students.

Objectives: While many studies have shown that student-athletes are a stigmatized group and topics related to them have received increasing attention, few studies have focused on the current situation of Chinese sports students () with the same dual identity as student-athletes. Thus, this study aims to understand and recognize the negative perceptions that students with sports identities experience in the Chinese educational and cultural context and the impact of these perceptions on them.

Methods: This qualitative study used an interpretive description methodology to collect data through semi-structured, in-depth interviews conducted by the researcher with 11 sports students, 4 regular students, 3 teachers, and 2 parents.

Reasons and promotion strategies of physical activity constraints in obese/overweight children and adolescents.

To explore the reasons for low levels of physical activity in obese/overweight children and adolescents and to propose appropriate strategies to promote their physical activity (PA). This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines by searching and analyzing the literature of studies related to physical activity in obese/overweight children and adolescents published between January 2003 and January 2023 in Web of Science, Scopus, and PubMed databases. A total of 31 relevant studies were included for analysis, of which 16 were quantitative and 15 qualitative.

Key transition technology of ski jumping based on inertial motion unit, kinematics and dynamics.

Background: The development and innovation of biomechanical measurement methods provide a solution to the problems in ski jumping research. At present, research on ski jumping mostly focuses on the local technical characteristics of different phases, but studies on the technology transition process are less.

Objectives: This study aims to evaluate a measurement system (i.

A Pulse Signal Preprocessing Method Based on the Chauvenet Criterion.

Pulse signals are widely used to evaluate the status of the human cardiovascular, respiratory, and circulatory systems. In the process of being collected, the signals are usually interfered by some factors, such as the spike noise and the poor-sensor-contact noise, which have severely affected the accuracy of the subsequent detection models. In recent years, some methods have been applied to processing the above noisy signals, such as dynamic time warping, empirical mode decomposition, autocorrelation, and cross-correlation.
