BACKGROUND: There is evidence for considerable heterogeneity in the responsiveness to regular physical activity (PA) which might reflect the influence of genetic factors. The aim of this systematic review was to assess whether the response to a PA intervention for measures of body composition and cardiorespiratory fitness is (i) correlated within twin pairs and/or families and (ii) more correlated in monozygotic twins (MZ) compared to dizygotic twins (DZ), which would be consistent with genetic effects...

CONTEXT:  Spinal musculature fatigue from vehicle exposure may place warfighters at risk for spinal injuries and pain. Research on the relationship between vehicle exposure and spinal musculature fatigue is conflicting. A better understanding of the effect of military duty on musculoskeletal function is needed before sports medicine teams can develop injury-prevention programs. OBJECTIVE:  To determine if the literature supports a definite effect of vehicle exposure on spinal musculature fatigue...

Injuries resulting from facial trauma are common in all sports. Athlete-to-athlete contact, falls, and blows from equipment account for the majority of these events. Appropriate knowledge of basic science, relevant anatomy, and clinical skills is required to provide the correct medical care. While true medical emergencies are infrequent, a prompt accurate diagnosis is essential in developing targeted management and return to play options.

In 1978 the Canadian Chiropractic Association recognized the need to establish an organization that would prepare chiropractors to treat athletic injuries and promote these services to sports organizations. Dr. Adrian Grice approached three chiropractors to establish such an organization. The Canadian Chiropractic Sports Academy (CCSA) was established in 1978. This was the start of the chiropractic sports movement which has seen chiropractors playing prominent roles as team doctors to professional and amateur teams and athletes and in the delivery of care at major national and international competitions...

BACKGROUND: Maximal oxygen uptake ([Formula: see text] 2max) is conventionally normalized to body size as a simple ratio or using an allometric exponent < 1. Nevertheless, the most appropriate body size variable to use for scaling and the value of the exponent are still enigmatic. Studies tend to be based on small samples and can, therefore, lack precision. OBJECTIVE: The objective of this systematic review was to provide a quantitative synthesis of reported static allometric exponents used for scaling [Formula: see text] 2max to whole body mass and fat-free mass...

Noseband tightness is difficult to assess in horses participating in equestrian sports such as dressage, show jumping and three-day-eventing. There is growing concern that nosebands are commonly tightened to such an extent as to restrict normal equine behaviour and possibly cause injury. In the absence of a clear agreed definition of noseband tightness, a simple model of the equine nose-noseband interface environment was developed in order to guide further studies in this area. The normal force component of the noseband tensile force was identified as the key contributor to sub-noseband tissue compression...

OBJECTIVES: Empirical research on the relationship between the built environment and health is increasing at a tremendous pace. However, findings from Anglo-American countries may not apply to the European context. Therefore, we systematically reviewed the existing evidence on the role of the built environment for leading risk factors and health behavior in Germany. METHODS: Through an extensive search via PubMed and Web of Science, using predefined selection criteria, two independent reviewers identified 25 empirical studies...

Horseracing has been called "one of the first quintessentially modern sports". Its urge towards standardization, its mathematically-set odds, concern with weights, and pioneering embrace of drug-testing reflect an empirical temperament crucial to its transformation from gentleman's pastime to global industry funded by wagering. Ironically, in the late 19th century, it was modern science itself, and in particular the purification and synthesis of the drugs of nature, that turned the doping of racing animals- a practice recorded in antiquity-into an organized criminal enterprise...

Cardio-respiratory fitness (CRF) is a widespread essential indicator in Sports Science as well as in Sports Medicine. This study aimed to develop and validate a prediction model for CRF based on a 45 second self-test, which can be conducted anywhere. Criterion validity, test re-test study was set up to accomplish our objectives. Data from 81 healthy volunteers (age: 29 ± 8 years, BMI: 24.0 ± 2.9), 18 of whom females, were used to validate this test against gold standard. Nineteen volunteers repeated this test twice in order to evaluate its repeatability...

A pediatrician is asked by her local school board to help them decide whether to discontinue their high school football program. She reviews the available evidence on the risks of football and finds it hopelessly contradictory. Some scholars claim that football is clearly more dangerous than other sports. Others suggest that the risks of football are comparable to other sports, such as lacrosse, ice hockey, or soccer. She finds very little data on the long-term sequelae of concussions. She sees claims that good coaching and a school culture that prioritizes the health of athletes over winning can reduce morbidity from sports injuries...

The mechanisms responsible for matching of the highly varying ATP demand by ATP supply in muscle are of primary importance for pure science, sport science and medicine. According to the traditional opinion ATP supply is activated by elevated ADP and Pi resulting from ATP hydrolysis during intensive work. Theoretical studies using the computer model of oxidative phosphorylation (OXPHOS) and the entire cell bioenergetic system developed by the author and co-workers lead to the each-step-activation (ESA) mechanism of the regulation of the system in skeletal muscle, heart and other tissues during work transitions...

A recovery process with optimal prerequisites, which is interrupted, is termed disrupted recovery. Whether this process has an influence on performance-related factors needs to be investigated. Therefore, the aim of this study was to examine how a short disturbance of a recovery phase is assessed and whether subsequent repeated sprint performance is affected by it. A quasi-experimental 2x2-factors cross-over design with 34 sport science undergraduate students (age 20.3 ± 2.1) was applied. Factors were the type of intervention (power nap vs...
