Effects of emotional intelligence on physical activity engagement and the mediating roles of achievement motivation and interpersonal relationship in Chinese undergraduate students.

Background: Engaging in physical activity has been demonstrated to enhance cardiorespiratory fitness, muscle strength, bone health, and cardiometabolic health. However, it is concerning that more than 80% of students globally do not meet the recommended standard of at least 1 h of physical activity per day. It is imperative to enhance student involvement in physical activities.

The effect of exercise motivation on college students' self-efficacy: the mediating roles of leisure satisfaction and mental toughness.

Background: The theory of motivation suggests that individual motivation is moderately stimulated to drive individuals to engage in the behaviors for which they are motivated. It is therefore that the moderate stimulation of exercise motivation will likely lead to the enhancement of college students' participation in exercise.

Objective: Investigate the effect of exercise motivation on college students' self-efficacy, reveal the mediating role of leisure satisfaction and mental toughness, and provide empirical evidence improving college students' self-efficacy through exercise motivation.

Clinical Analysis of Myocardial Injury in Highlanders with Pulmonary Hypertension.

Pulmonary hypertension (PH) is a prevalent adverse cardiovascular event at high-altitude environments. Prolonged exposure to high altitudes may result in myocardial injury, which is associated with poor clinical outcomes. This study aims to investigate the clinical characteristics of myocardial injury in patients with PH at high altitude.

Study on Allele Specific Expression of Long-Term Residents in High Altitude Areas.

In diploid organisms, half of the chromosomes in each cell come from the father and half from the mother. Through previous studies, it was found that the paternal chromosome and the maternal chromosome can be regulated and expressed independently, leading to the emergence of allele specific expression (ASE). In this study, we analyzed the differential expression of alleles in the high-altitude population and the normal population based on the RNA sequencing data.

The relationship between self-concept clarity, athletic identity, athlete engagement and the mediating roles of quality of life and smartphone use in Chinese youth athletes.

Background: Youth athletes represent the future of competitive sports, so examining their commitment to sport is critical. This study investigated the impacts of self-concept clarity and athletic identity on athlete engagement among Chinese youth athletes, and the mediating roles of quality of life and smartphone use.

Methods: 410 youth athletes from sports schools completed an online cross-sectional survey measuring self-concept clarity, athletic identity, quality of life, smartphone use, and athlete engagement.

Effect of altitude training on the aerobic capacity of athletes: A systematic review and meta-analysis.

Purpose: With a growing number of athletes and coaches adopting altitude training, the importance for rationalizing and optimizing such training has been emphasized. We conducted a meta-analysis to evaluate the influence of altitude training on athletes' aerobic capacity and to explore the best altitude training method to improve this capacity.

Methods: We searched Web of Science, SpringerLink, Science Direct, EBSCO, and PubMed databases combined with manual search of the references to collect studies indexed from 1979 to September 2020 on the effect of altitude training on athletes' aerobic capacity.

Effect of exercise intervention on primary insomnia: a meta-analysis.

Introduction: Exercise can have a positive effect on body functioning and immunity. This study systematically evaluated the effect of exercise intervention on patients diagnosed with primary insomnia. Based on the meta-analysis, we developed exercise recommendations to help improving sleep quality in these patients.

Biomimetic and osteogenic 3D silk fibroin composite scaffolds with nano MgO and mineralized hydroxyapatite for bone regeneration.

Artificial bioactive materials have received increasing attention worldwide in clinical orthopedics to repair bone defects that are caused by trauma, infections or tumors, especially dedicated to the multifunctional composite effect of materials. In this study, a weakly alkaline, biomimetic and osteogenic, three-dimensional composite scaffold (3DS) with hydroxyapatite (HAp) and nano magnesium oxide (MgO) embedded in fiber (F) of silkworm cocoon and silk fibroin (SF) is evaluated comprehensively for its bone repair potential in vivo and in vitro experiments, particularly focusing on the combined effect between HAp and MgO. Magnesium ions (Mg) has long been proven to promote bone tissue regeneration, and HAp is provided with osteoconductive properties.

Effects of Psychological Interventions on the Prevention of Sports Injuries: A Meta-analysis.

Background: Studies have shown that preventive psychological interventions can reduce the occurrence of sports injuries.

Purpose: To systematically evaluate the published literature on the effects of psychological interventions on rates of sports injuries and propose a set of psychological interventions to reduce such injuries.

Study Design: Systematic review; Level of evidence, 1.

Exercise-Based Interventions for Internet Addiction: Neurobiological and Neuropsychological Evidence.

With the increase in the number of internet users, the problems associated with excessive internet use have become increasingly obvious. Internet addiction can alter neurobiology, and its symptoms can be alleviated through exercise, but whether exercise exerts these effects through neurobiological pathways is unclear. Here, we reviewed the neurobiological mechanisms of exercise-based interventions against internet addiction by searching PubMed and Google Scholar for relevant research using such keywords as "exercise", "internet addiction", "hypothalamic-pituitary-adrenal axis", "neurotrophin", and "dopamine".
