Multi-criteria decision-making in soccer
Multi-criteria decision-making (MCDM) methods have been increasingly applied in football to support complex managerial and performance-related decisions; however, a comprehensive mapping of the research landscape is still lacking. This study examines the evolution of MCDM research in football by identifying publication trends, influential authors, leading institutions, collaboration networks, and emerging thematic clusters. A bibliometric analysi…
Cross-cultural adaptation and psychometric evaluation of the Engaged Teachers Scale among Arabic-speaking physical education teachers
Background Teacher engagement is a positive psychological state characterized by vigor, dedication, and absorption in professional activities, representing the opposite of burnout. While research has established the importance of engagement for teacher effectiveness, wellbeing, and student outcomes, validated measurement tools for assessing engagement among physical education teachers in Arabic-speaking contexts are lacking. This study addresses …
Transcultural validation of the “Teacher Stress Inventory” (TSI) in Arabic
Background The Teacher Stress Inventory (TSI) is an instrument for assessing the multifaceted stressors experienced by educators. However, its original English format necessitates cultural adaptation to ensure relevance for Arabic-speaking contexts. Aim This study aimed to validate the TSI in Arabic for Tunisian teachers, assessing its psychometric properties, including factorial structure, internal reliability, construct validity, and sensitivit…
Adaptation and validation of the Collective Efficacy Questionnaire for Sport (Ceqs) in Arabic
The Arabic adaptation of the CEQS addresses the pressing need in sports psychology, allowing assessment of collective efficacy in Arabic-speaking teams and facilitating cross-cultural comparisons of team dynamics. This study undertook a rigorous translation and back-translation process for the CEQS, engaging athletes from a variety of sports in both exploratory (n = 477) and confirmatory (n = 510) phases. Exploratory and confirmatory factor analy…
Position-specific biomarker responses to match vs. Vameval test modalities in elite female soccer players
To examine the effects of exercise type (competitive match vs. VAMEVAL test) and playing position on biomarker responses in elite female soccer players, twenty-one athletes (seven each: defenders, midfielders, attackers) participated in this cohort-based study. Blood samples were collected before and 3 minutes after both a competitive match and VAMEVAL test, analyzing 19 biomarkers including metabolic, lipid, protein, inflammatory, and immune par…

A comparative analysis of autograft choices of anterior cruciate ligament reconstruction and their effects on muscle strength and joint biomechanics
IntroductionAnterior cruciate ligament reconstruction (ACLR) is crucial to restore knee stability and function after ACL injuries, especially in physically active individuals. Despite advances in surgical techniques and rehabilitation protocols, the choice of autograft has a significant impact on postoperative recovery, particularly on muscle strength and joint biomechanics. In this study, the effects of four autografts are investigated: Iliotibi…
Cross-cultural adaptation and validation of an Arabic version of the Cognitive-Affective Mindfulness Scale (Cams-R)
No Arabic version of the Revised Cognitive-Affective Mindfulness Scale (CAMS-R) was found, prompting this study’s threefold objectives: first, to validate an Arabic translation of CAMS-R among Tunisian students; second, to assess its factor structure and reliability; and third, to explore its validity by investigating the relationship between CAMS-R scores, grit, and academic success. Cross-sectional online data were collected from 705 university…
Injury Profiling in Male Police Cadets During Initial Training Phase
Musculoskeletal injuries during the “Initial Training Phase” (ITP) are a major medical problem faced by law enforcement agencies worldwide. Aiming to develop an injury prevention strategy, we examined the incidence, type, associated factors, and severity of injuries and secondarily tracked their evolution over time by batches in a police academy. A retrospective cohort study was conducted using prospectively collected injury data on 979 newly rec…
Examining the interplay between physical activity, problematic internet use and the negative emotional state of depression, anxiety and stress
Findings suggest that relationships between PIU and negative emotional state of depression, anxiety and stress are mediated via physical exercise. These results underscore the importance of the physical activity factor in the studies analyzing longitudinal effects of PIU on mental health outcomes
ChatGPT is not ready yet for use in providing mental health assessment and interventions
As for July 2023, ChatGPT failed to give the simple medical advice given certain clinical scenarios. This supports that the quality of ChatGPT-generated content is still far from being a guide for users and professionals to provide accurate mental health information. It remains, therefore, premature to conclude on the usefulness and safety of ChatGPT in mental health practice
The impact of intermittent fasting during Ramadan on psychomotor and cognitive skills in adolescent athletes
Introduction Intermittent fasting (IF) represents a dietary intervention similar to caloric restriction, characterized by the strategic limitation of food consumption. Among the diverse array of practices for IF, Ramadan IF (RIF), a religious observance in Islam, mandates that healthy adult Muslims abstain from both food and drinks during daylight hours. In sports, researchers have extensively studied IF effects on health, including sleep and phy…
Exploring the impact of verbal encouragement on strength, endurance, and psychophysiological responses
Introduction This study investigates the effects of teacher verbal encouragement (VE) on strength, endurance, and psychophysiological responses, aiming to enhance teaching strategies in sports science education. Methods Forty-eight sports science students, aged 21.3 ± 0.5 years, participated in this study. The sample was randomly divided into two groups, and a counterbalancing procedure was implemented. Participants completed strength and enduran…
From human writing to artificial intelligence generated text
Natural language processing (NLP) has been studied in computing for decades. Recent technological advancements have led to the development of sophisticated artificial intelligence (AI) models, such as Chat Generative Pre-trained Transformer (ChatGPT). These models can perform a range of language tasks and generate human-like responses, which offers exciting prospects for academic efficiency. This manuscript aims at (i) exploring the potential ben…
Reliability and validity of the Arabic version of coach-athlete relationship questionnaire
This study had a twofold purpose: (a) to create an Arabic version of the Coaches-Athletes Relationship Questionnaire (CART-Q) and (b) to assess its psychometric qualities in the context of Tunisia, as well as its sensitivity in other sports populations. The researchers conducted an online survey of 594 amateur athletes from different sports clubs in Tunisia. For the exploratory factor analysis, 157 athletes aged 22.72 ± 3.78 years were randomly s…
The Effect of Daytime Ingestion of Melatonin on Thyroid Hormones Responses to Acute Submaximal Exercise in Healthy Active Males
It is well known that exercise increases the activity of thyroid glands and raises the blood level of melatonin. The increase of melatonin during exercise may be linked to a rise in thyroid-stimulating hormone (TSH). No previous study has investigated the combined effects of melatonin ingestion and acute submaximal exercise on thyroid hormones’ responses. The purpose of this pilot study was to explore the effects of daytime ingestion of melatonin…
Biological Responses to Short-Term Maximal Exercise in Male Police Officers
The specifics of short-term physical exercise are similar to the immediate reaction demands placed on police officers. Identifying the physiological predisposition to short-term high-intensity exercise in male law enforcement officers will assist in understanding their metabolism and make a significant contribution to a much more personal and individualized workout program. This will improve physical fitness of individual officers, improving thei…
Sleep Quality and Physical Activity as Predictors of Mental Wellbeing Variance in Older Adults during Covid-19 Lockdown
COVID-19 lockdown deleteriously affected physical activity and sleep patterns. Furthermore, change in the total PSQI score and total physical activity energy expenditure were significant predictors for the decrease in mental wellbeing
