Objective: Research on active videogames (AVGs) has demonstrated the motivation-boosting power of the Köhler effect (a motivating force for "weak links" in groups based on group principles of upward social comparison and indispensability) with software-generated partners (SGPs), but the effect has yet to be examined over time. We tested the viability of the Köhler effect in an AVG with an SGP over 12 exercise sessions using a cycle ergometer and whether a fatiguing partner (FP) could further boost the effect.
Materials And Methods: A repeated-measures design was used to assess mean changes in exercise persistence over time. Participants were randomly assigned to one of three game conditions: AVG alone (individual-control [IC]), AVG with a consistently superior partner (CSP), or AVG with a superior partner who showed signs of fatigue (FP). Assessments were conducted on 82 participants (42 college students and 40 adults from the community) in a laboratory over 12 experimental sessions. The main outcome measure was exercise persistence (minutes of gameplay cycling at 75% HRmax).
Results: Data yielded significant improvements in exercise duration for men in the FP condition when compared with men in the IC condition (Mdiff = 12:32 minutes, SEdiff = 4:54). Women showed no change in exercise persistence over time and no condition differences.
Conclusion: Exercising in an AVG with a superior SGP, who shows signs of fatigue over time, improved exercise persistence for men but not for women under present experimental conditions.

Physiotherapists are critically positioned to integrate education into patient care, including pain science education (PSE) to enhance management and outcomes. Anecdotally, many physiotherapists report difficulty providing PSE in private practice settings. Here, we aimed to explore current PSE use, knowledge, and barriers to implementation.

Traumatic brain injury (TBI) is a burdensome condition frequently associated with an increased risk of psychiatric disorders. Although the exact molecular signaling pathways have not yet been fully defined, the compromised integrity of functional brain networks in regions such as the prefrontal cortex and anterior cingulate cortex has been linked to persistent symptoms, including depression, fatigue, and sleep disorders. Understanding how TBI affects neural physiology enables the development of effective interventions.

Background/objectives: The COVID-19 pandemic has led to detrimental effects on diverse aspects of the mental and physical health of the general population worldwide. The elderly are more susceptible to COVID-19 infection compared to younger age groups. In this aspect, the purpose of the current survey is to evaluate the effect of the COVID-19 pandemic on the interrelationships among the sociodemographic and anthropometric characteristics, depressive behavior, quality of life, cognition status, physical activity and nutritional status of older adults.

Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), is increasingly recognized as a condition affecting not only adults but also children and adolescents. While children often experience milder acute COVID-19 symptoms compared to adults, some develop persistent physical, psychological, and neurological symptoms lasting for weeks or months after initial infection. The most commonly reported symptoms include debilitating fatigue, respiratory issues, headaches, muscle pain, gastrointestinal disturbances, and cognitive difficulties, which significantly impact daily activities, schooling, and social interactions.
