Evolution of injury burden in Qatari professional football - 8 season data from the Aspetar Injury and Illness Surveillance Programme.

Prospectively collected injury surveillance data are essential for designing and implementing injury prevention programmes. We investigated the incidence, characteristics and patterns of professional football injuries in Qatar, providing details on the most observed injuries' burden. We prospectively recorded individual time-loss injuries and training/match exposure from 17 professional football teams in Qatar during 8 seasons (2014/15 to 2021/22).

Effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders: A comprehensive systematic review with meta-analysis.

Background: Usually, patients with hand, wrist/forearm disorders report musculoskeletal complaints in the shoulder. Although, role of scapula is fundamental for movement and functional stability across the upper limb kinetic chain; however, there are no systematic reviews and meta-analyses that have analyzed the effect of scapular exercises in these patients.

Purpose: This study aimed to determine the effectiveness of a scapular exercise program on functional outcomes in patients with hand, wrist or elbow disorders.

Peak Oxygen Consumption Scaled to Body Composition Is Associated With Mortality and Morbidity in People With a Fontan Circulation.

Background: Peak oxygen consumption (peak O) is traditionally scaled by body mass, but it is most appropriately scaled by fat-free mass. However, it is unknown whether peak O scaled by fat-free mass is associated with mortality and morbidity in people with a Fontan circulation. The aim of this study was to assess the associations between different expressions of peak O with mortality and morbidity in people with a Fontan circulation.

Limited evidence for the usage of renin-angiotensin-aldosterone pathway blockers to prevent arthrofibrosis after total knee arthroplasty. A systematic review of clinical evidence.

Purpose: Despite advances in surgical techniques and rehabilitation protocols, arthrofibrosis following total knee arthroplasty (TKA) still has poor outcomes. In the last decade, attention has been focused on the pathogenesis and cascade of events leading to the development of fibrosis. Currently, one of the most promising approaches consists in the indirect antagonisation of transforming growth factor beta 1 () through the downregulation of the renin-angiotensin-aldosterone system (RAAS).

Methods: Between September 2016 and December 2020 all athletes (≥18) with an acute ankle injury presenting within 7 days post-injury were screened for eligibility.

Translation and validation of sleep questionnaires in Jordanian and Qatari athletes.

Purpose: To translate two prominent sleep questionnaires, the Functional Outcomes of Sleep Questionnaire 10 (FOSQ-10) and the Sleep Hygiene Index (SHI), into Arabic.

Methods: The translations adhered to the established international criteria and underwent subsequent validation among 130 Arabic-speaking athletes from Jordan and Qatar. The validation process involved comparison against existing Arabic sleep questionnaires to ensure linguistic and cultural appropriateness.

Effects of thermal interventions on skeletal muscle adaptations and regeneration: perspectives on epigenetics: a narrative review.

Recovery methods, such as thermal interventions, have been developed to promote optimal recovery and maximize long-term training adaptations. However, the beneficial effects of these recovery strategies remain a source of controversy. This narrative review aims to provide a detailed understanding of how cold and heat interventions impact long-term training adaptations.

Medium-term results of arthroscopic hip surgery compared with physiotherapy and activity modification for the treatment of femoroacetabular impingement syndrome: a multi-centre randomised controlled trial.

Objective: To report a 3-year follow-up from the FemoroAcetabular Impingement Trial, comparing arthroscopic surgery with physiotherapy in the management of femoroacetabular impingement (FAI) syndrome for the dual primary outcomes of radiographic hip osteoarthritis (OA) and patient-reported outcome measures of activities of daily living.

Methods: Two-group parallel, assessor-blinded, pragmatic randomised controlled trial across seven sites. 222 participants aged 18-60 years with FAI syndrome confirmed clinically and radiologically were randomised (1:1) to receive arthroscopic hip surgery (n=112) or physiotherapy (n=110).

Low-dose carbon monoxide inhalation to increase total hemoglobin mass and endurance performance: scientific evidence and implications.

Recently, chronic intermittent inhalation of low-dose carbon monoxide (CO) has been postulated as a practice to increase total hemoglobin mass with potential beneficial effects on endurance performance. In this perspective article, we discuss the potential performance enhancing capabilities as well as the safety concerns, which include individual variability in CO response, and acute and chronic health effects. It is also important to note that according to the World-Anti-Doping-Agency (WADA), CO inhalation could fall under "" and therefore could be considered a prohibited method if used as a non-diagnostic tool.

Background: Animal research suggests that repeated heat exposures may stimulate skeletal muscle protein synthesis and downregulate protein degradation.

Hypothesis: Repeated heat exposures during ankle immobilization and rehabilitation would preserve human muscle strength and mass.

Study Design: Controlled laboratory study.
