Correlation of muscle strength, working memory, and activities of daily living in older adults.

Objective: This study aims to investigate the relationship between muscle strength, working memory, and activities of daily living (ADL) in older adults. Additionally, it seeks to clarify the pathways and effects of working memory in mediating the relationship between muscle strength and ADL.

Methods: Using a cross-sectional study design, we recruited 245 older adults individuals from nursing homes.

Standardization of gut microbiome analysis in sports.

The gut microbiome plays a significant role in physiological functions such as nutrient processing, vitamin production, inflammatory response, and immune modulation, which, in turn, are important contributors to athlete health and performance. To date, the interpretation, discussion, and visualization of microbiome results of athletes are challenging, due to a lack of standard parameters and reference data for collection and comparison. The purpose of this perspective piece is to provide researchers with an easy-to-understand framework for the collection, analysis, and data management related to the gut microbiome with a specific focus on athletic populations.

Local environment perceived in daily life and urban green and blue space visits: Uncovering key factors for different age groups to access ecosystem services.

Inequality in access to green and blue spaces is a major issue in the field of environmental justice. Various factors significantly influence visitations to these spaces, including residential, commuting, and shopping areas. However, studies have mainly focused on residential environments.

Effects of exercise with or without -hydroxy--methylbutyrate supplementation on muscle mass, muscle strength, and physical performance in patients with sarcopenia: a systematic review and meta-analysis.

Objectives: This systematic review and meta-analysis aimed to assess the effects of exercise with/without -hydroxy-β-methylbutyrate (HMB) supplementation on muscle mass, muscle strength, physical performance, and body composition in patients with sarcopenia.

Methods: A literature search for randomized controlled trials (RCTs) on the effects of exercise with or without HMB supplementation on muscle mass, muscle strength, physical performance, and body composition in patients with sarcopenia was conducted using PubMed, Web of Science, EBSCO, The Cochrane Library, EMBASE, Scopus, Science Direct, China Knowledge Resource Integrated Database (CNKI), and Wan Fang database. The search was limited to studies published up to April 2024 for each database.

Psychophysiological markers of athlete burnout: a call to arms.

Burnout is a growing problem in high-performance sport and has negative consequences for athletes (e.g., mental ill-health).

The HAPPY concept mapping study: "To prevent injuries in young handball players it's important to…" - Perceptions among stakeholders.

Objectives: This study aimed to identify facilitators for implementing injury prevention initiatives in youth handball, and to assess stakeholders' perceptions of their importance and feasibility.

Design: Mixed-method concept mapping study.

Methods: Four stakeholder groups - coaches, administrators, health staff and players - participated in this mixed-method concept mapping study.

Moderate physical activity and higher frequency are inversely associated with incidence of frailty in middle-aged and older population: a 4-year longitudinal study in Europe.

Background: Global aging is leading to an increase in frailty patients, and physical activity (PA) may have an impact on frail in middle-aged and older population. This study aimed to explore the relationship between the frequency of different PA intensities and the incidence and prevalence of frailty in middle-aged and older adults based on the Survey of Health, Ageing, and Retirement in Europe (SHARE).

Method: Self-reported questionnaires were used to obtain information on demographics and PA, and frailty was assessed using the SHARE Frailty Instrument (SHARE-FI).

The impact of the massive open online course C19_SPACE during the COVID-19 pandemic on clinical knowledge enhancement: a study among medical doctors and nurses.

Purpose: During the initial phase of the pandemic, healthcare professionals faced difficulties due to the limited availability of comprehensive learning resources on managing patients affected with coronavirus disease 2019 (COVID-19). The COVID-19 Skills Preparation Course (C19_SPACE) was tailored to meet the overwhelming demand for specialized training. The primary objective of this study was to assess the efficacy and impact of this program on enhancing clinical knowledge and to identify factors affecting this improvement.

Effects of Inertial Flywheel Training vs. Accentuated Eccentric Loading Training on Strength, Power, and Speed in Well-Trained Male College Sprinters.

This study aimed to evaluate and compare the effects of inertial flywheel training and accentuated eccentric loading training on the neuromuscular performance of well-trained male college sprinters. Fourteen sprinters were recruited and randomly assigned to either the flywheel training (FWT, = 7) group or the accentuated eccentric loading training (AELT, = 7) group. The FWT group completed four sets of 2 + 7 repetitions of flywheel squats, whereas the AELT group performed four sets of seven repetitions of barbell squats (concentric/eccentric: 80%/120% 1RM).

How Sports Involvement and Brand Fit Influence the Effectiveness of Sports Sponsorship from the Perspective of Predictive Coding Theory: An Event-Related Potential (ERP)-Based Study.

With the rapid expansion of the global sports market, the significance of sports sponsorship has attracted growing attention. However, during the golden age of the sports industry's development in China, international sports brand giants such as Nike, Adidas, and Under Armour have rapidly captured a substantial share of the Chinese sports consumer market through their distinctive product designs and varied marketing strategies. This has resulted in a highly competitive environment for China's sports goods industry.

What do we Know about Complex-Contrast Training? A Systematic Scoping Review.

Background: The complex-contrast training (CCT) method utilizes two exercises with different loads and movement velocities in a set-by-set fashion to induce multiple neuromuscular adaptations. The speculated primary mechanism involves the post-activation potentiation or post-activation performance enhancement (PAPE) of the muscles used during the heavy load (low velocity) exercise, thereby improving the performance of lower load (high velocity) exercise. However, no previous study has attempted to systematically synthesize the available evidence on CCT (e.

The pathway of social support in enhancing adolescents' physical fitness: The mediating roles of physical activity and self-efficacy.

Purpose: Utilising Welk's Youth Physical Activity Promotion (YPAP) model as a foundational framework, this study investigates the intricate interplay of social support, physical activity (PA), and self-efficacy in relation to physical fitness within the context of Chinese culture. The primary objective is to identify the nuanced dynamics among social support, self-efficacy, PA, and physical fitness to enhance adolescent well-being and fitness.

Methodology: The study employed a convenience sampling method, engaging 123 adolescents aged 18-21, of which 67 were females (54.

Cool mama: Temperature regulation during high-intensity interval running in pregnant elite and recreational athletes.

Background: Regular exercise during pregnancy is beneficial, but athletes often exceed the recommended 150 min of moderate-intensity activity, incorporate high-intensity exercises. The upper limit for exercise intensity and duration on fetal and maternal safety remains uncertain. A concern is a maternal core body temperature of >39.
