A 26-year-old man presented to a direct-access physical therapy clinic with right shoulder pain that began 1 week prior, after forceful abduction and external rotation during combatives training. Radiographs were noncontributory. Due to suspicion of a pectoralis major tear, the patient was referred to an orthopaedic surgeon. Magnetic resonance images were ordered for assessment of the pectoralis musculature, and a magnetic resonance arthrogram for the right shoulder. The magnetic resonance images confirmed complete pectoralis major tendon detachment from the humerus, and the magnetic resonance arthrogram confirmed an extensive, near-circumferential labral tear with a reverse Bankart fracture...

The integration of technology into training and competition sport settings is becoming more commonplace. Inertial sensors are one technology being used for performance monitoring. Within combat sports, there is an emerging trend to use this type of technology; however, the use and selection of this technology for combat sports has not been reviewed. To address this gap, a systematic literature review for combat sport athlete performance analysis was conducted. A total of 36 records were included for review, demonstrating that inertial measurements were predominately used for measuring strike quality...

[Introduction: The city of Villeurbanne has made the political choice to reduce social inequalities in health (SIH). The Public Health Department wanted to assess the health impact in the context of this project. The main objective was to analyse the links between urban development and health in order to identify the impact of the urban project on health and to make recommendations to reduce physical inactivity of children. Attention was focused on a neighbourhood of 6,000 inhabitants in the process of urban renewal. A high rate of adults on antidiabetic treatment was observed in this relatively deprived neighbourhood. School medicine also noted a high proportion of overweight children in schools in the neighbourhood, higher than in all schools of the city. The objective of this HIA was therefore to identify the impact of the renovation project on children’s mobility and to make recommendations in order to combat their physical inactivity by encouraging spontaneous physical activity.Methods: The selected determinants were grouped into four categories: outdoor environment, use of open spaces, adapted sports facilities/equipment, roads. The evaluation was based on analysis of urban planning documents, environmental analysis reports, ad hoc surveys, individual interviews with the various partners and target actors. A bibliographic review confirmed the positive or negative impacts of various aspects of the project on health.Results: Although some aspects of the project had a positive impact on the health of the inhabitants, others have a negative impact on children’s mobility, well-being and social capital. About 30 recommendations were proposed and prioritized according to their political support and their technical, economic and temporal feasibility.Discussion].

The main focus of this review is illness amongst elite athletes, how and why it occurs, and whether any measures can be taken to combat it or to prevent its onset. In particular, there is particular interest in exercise-induced immunodepression which is a result of the immune system regarding exercise (for example, prolonged, exhaustive exercise) as a challenge to its function. This promotes the inflammatory response. There is often a high incidence of illness in athletes after undertaking strenuous exercise, particularly among those competing in endurance events, mainly in terms of upper respiratory tract illness (URTI) but also involving gastrointestinal problems...

OBJECTIVE: For concussions to be effectively managed in sports, they need to be correctly identified and reported. The extent to which professional athletes correctly recognize concussions, and their willingness to report symptoms, is not yet well understood. Given the risk of head injuries leading to concussions across combat sports, insight into professional fighters' knowledge and reporting of concussive symptoms is essential to improve concussion management. METHOD: To investigate understanding and reporting patterns of concussions sustained while training or competing, 257 fighters completed a self-report questionnaire assessing self-perception of concussion knowledge, trust of ringside medical providers, and reported number of previous head injuries...

BACKGROUND: Oesophageal carcinoma (OC) is one of the leading cancers in Sri Lanka. Its increasing incidence despite the implementation of various preventive activities addressing the conventional risk factors indicates the possibility of the existence of novel, country-specific risk factors. Thus, the identification of novel risk factors of OC specific to Sri Lanka is crucial for implementation of primary prevention activities. METHODS: A case-control study was conducted among 49 incident cases of OC recruited from the National Cancer Institute, Maharagama using a non-probability sampling method, and unmatched hospital controls (n = 196) excluded of having OC recruited from the endoscopy unit of the National Hospital of Sri Lanka...

Hydration is one of the most significant issues for combat sports as athletes often use water restriction for quick weight loss before competition. It appears that alkaline water can be an effective alternative to sodium bicarbonate in preventing the effects of exercise-induced metabolic acidosis. Therefore, the main aim of the present study was to investigate, in a double blind, placebo controlled randomized study, the impact of mineral-based highly alkaline water on acid-base balance, hydration status, and anaerobic capacity...
