Falls pose a significant health risk for older adults, often due to balance disorders and decreased mobility. The ability to perform sit-to-stand transfers, which involve squatting, is crucial for daily independence. Incorporating squats into exercise routines can enhance lower body strength, reduce fall risk, and improve overall quality of life.

This study investigates the dynamic interactions between physiological systems during competitive gaming, utilizing a Network Physiology approach. By examining the physiological responses of a gamer with attention-deficit/hyperactivity disorder playing a real-time strategy game, we explore the relationships and temporal lag effects between pupil dilation, skin temperature, and heart rate. Our findings highlight the interconnectedness of these physiological systems and demonstrate how different physiological states are associated with unique patterns of network interactions.

(MT), a construct linked to high-stress performance, is predominantly studied via self-assessment in cross-sectional designs. In the firefighting context, where no dedicated MT instrument exists, the Sports Mental Toughness Questionnaire (SMTQ) and the Military Training Mental Toughness Inventory (MTMTI) have been used. However, their reliability and concurrent validity remain unexamined.

Nursing professional development practitioners are faced with meeting the onboarding needs of internationally educated nurses (IENs) recruited to work in the United States. The purpose of this secondary data analysis study was to assess differences between demographic characteristics, orientation, and onboarding variables and IEN's length of orientation and retention to a healthcare system. A significant difference in the length of orientation by unit assigned, degree type, and retention were discovered.

This study investigated the impact of auditory stimuli on muscular activation patterns using wearable surface electromyography (EMG) sensors. Employing four key muscles (Sternocleidomastoid Muscle (SCM), Cervical Erector Muscle (CEM), Quadricep Muscles (QMs), and Tibialis Muscle (TM)) and time domain features, we differentiated the effects of four interventions: silence, music, positive reinforcement, and negative reinforcement. The results demonstrated distinct muscle responses to the interventions, with the SCM and CEM being the most sensitive to changes and the TM being the most active and stimulus dependent.

Depressive mood states in healthy populations are prevalent but often under-reported. Biases exist in self-reporting of depression in otherwise healthy individuals. Gait and balance control can serve as objective markers for identifying those individuals, particularly in real-world settings.

Purpose: To investigate longitudinally the role of mental toughness (MT) in knee rehabilitation in terms of perceived pain and functionality in a sample of older adults with arthritis who adhered to their postsurgery clinic-based rehabilitation protocols and provide suggestions to rehabilitation psychologists.

Design: To strengthen the internal validity of this study, we designed our methods and implementation in a way to minimize bias by utilizing the National Institute of Health Quality Assessment Tool for Before-After (Pre-Post) Studies With No Control Group. The data were collected from 92 older-adult patients, who had a diagnosis of osteoarthritis and underwent knee surgery.

Mental toughness (MT) is a popularized term in sports since it has been found to be positively related to performance. Self-assessment is the most common method of MT data collection. In the strength and conditioning (S&C) context, MT research has focused on males with a notable lack of female participants.

The sport industry has never seen growth such as eSports'. Using synchronized monitoring of two biological processes on a 25-year-old gamer, we investigated how his brain ( EEG) and eyes ( pupil dilation) interacted dynamically over time as an integrated network during NBA2K playing time. After the spectral decomposition of the different Brain and Eye signals into seven frequency bands, we calculated the bivariate equal-time Pearson's cross-correlation between each pair of EEG/Eye spectral power time series.

Sport cultures transmit values for anticipated conduct. Recent events have resulted in injuries/deaths of National Collegiate Athletic Association (NCAA) student-athletes, usually during off-season football training. Through media reports, strength and conditioning coaches (SCC) have been allegedly involved by incorporating military-style training (MST).

Background: Health and social care staff are at high risk of experiencing adverse mental health (MH) outcomes during the COVID-19 pandemic. Hence, there is a need to prioritize and identify ways to effectively support their psychological well-being (PWB). Compared to traditional psychological interventions, digital psychological interventions are cost-effective treatment options that allow for large-scale dissemination and transcend social distancing, overcome rurality, and minimize clinician time.

Law enforcement agencies generally employ the "one-size-fits-all" education-training model. Its effectiveness compared to alternative training models has been under scrutiny. Physical fitness scores of Serbian male (n = 98) and female (n = 79) police cadets during their yearly evaluation were compared.

Recent tragic events and data from official NCAA reports suggest student-athletes' well-being is compromised by symptoms of mental health (MH) disorders. Self-compassion (SC) and mental toughness (MT) are two psychological constructs that have been shown effective against stressors associated with sports. The purpose of this study was to investigate SC, MT, and MH in a NCAA environment for the first time and provide practical suggestions for MH best practice No.

Objective: To investigate the efficacy of interventions designed to train and develop mental toughness (MT) in sport.

Design: Systematic review and meta-analysis.

Data Sources: Journal articles, conference papers and doctoral theses indexed in Embase, Scopus, PubMed and SPORTDiscus from inception to 22 November 2019.

Background:: The development of athlete-specific electrocardiogram (ECG) interpretation standards, along with recent rates of sudden cardiac death (SCD) in athletes being higher than previously estimated, has heightened the debate in the sports medicine community regarding cardiovascular screening of the college athlete, including whether certain high-risk subsets, such as male basketball athletes, should undergo more intensive screening.

Hypothesis:: ECG and/or echocardiography screening in National Collegiate Athletic Association Autonomous 5 Division I (A5DI) schools will be more common than previous reports, and there will be more frequent use of noninvasive cardiac screening for men's basketball players than the general athlete population.

Study Design:: Cross-sectional, quantitative study.

Background: Sedentary behavior is associated with negative health consequences independent of physical activity levels. Evidence suggests the work environment promotes sedentary behavior regardless of sector, and that employees with occupations requiring longer sitting times differ only marginally in leisure sitting time from those with more active occupations. Because physical activity opportunities may be limited across many work settings, leisure sedentary time may be more easily replaced with physical activity.
