PURPOSE: The purpose of this study was to explore how an exclusive sample of women's national football team coaches described how they implement careful coaching while facing social and organizational pressure to win medals. METHOD: To consider coaches' negotiations, we drew on Noddings' concept of caring. Using an interpretive research paradigm, we conducted in-depth interviews with five Swedish women's national football team coaches. An abductive approach was used to simultaneously process the theoretical framework of "ethics of care" and the empirical data...

Within the Paracanoeing discipline, it is important to ensure that appropriate control is achieved by a paddler with a disability. However, this Paralympic Games discipline has seen very little attention to date. The aims of this study were to understand the kinematic impact to a paracanoeist when not utilizing the use of a prosthetic lower-limb. A kayaker with a uni-lateral transfemoral amputation completed several 200 m maximal efforts both with and without their prosthesis. When the prosthetic limb was removed, there were significant differences found in stroke rate, stroke speed, stroke length and overall power output...

OBJECTIVES: Posterior cruciate ligament (PCL) injuries are relatively common injuries associated with athletic activities and high-energy trauma. Posterolateral corner (PLC) injuries frequently accompany injury to the PCL. Diagnosis can be challenging and requires a comprehensive history and physical examination. Patients frequently report vague, nonspecific symptoms and the mechanism of injury is often useful in localizing injured structures. Two of the more common mechanisms for PCL injury include a direct blow to the proximal anterior tibia with the knee flexed, as well as a significant knee hyperextension injury...

INTRODUCTION: Energy drinks (EDs) have become an integral part of the young adult, athletic, and military culture. Many athletes are convinced that EDs enhance performance, and service members as well as college students frequently use EDs as stimulants to counter sleep deprivation, or to improve academic performance. However, concerns have been raised by some military leaders about potential adverse effects of EDs. MATERIALS AND METHODS: A needs assessment survey of a convenience sample of military health care providers was conducted and identified EDs as a top knowledge need for those providers working in the area of traumatic brain injury (TBI)...

Although sports activities are generally considered beneficial to people's health and well-being, they can cause injuries and increased fatigue. Guided by the Demand-Induced Strain Compensation Recovery Model, this study hypothesized that physical recovery and mental detachment from sport-related activities would prevent injury and enhance mental energy. A cross-sectional survey study was conducted among 161 recreational athletes. Structural equation modelling analyses showed that mental detachment was negatively associated with injury and positively associated with mental energy...

Amino acids playing important roles in metabolic processes are often included in dietary supplements whose use has largely expanded over the last 20 years not only in patients with particular deficiencies, but also in athletes and even common people that want to enrich their regular daily diet. In the present study, a bare silica Kinetex core-shell 2.6μm HILIC column was used for separation of some important hydrophilic amino acids and amino acids-like molecules i.e., aspartic acid, creatine, carnitine, arginine and the tripeptide glutathione (GSH), by optimizing the chromatographic conditions for their determination in complex alimentary supplements...

Cross-country skiers change technique depending on terrain (incline) and effort (work rate; speed at a particular incline or resistance). The literature is not unequivocal about the influence of incline or speed on the choice of technique, i.e., which of these act as a 'control parameter'. Identifying task related control parameters for spontaneous technique shifts assists elucidating which mechanisms are active for triggering technique transitions. The aim of this study was to investigate whether speed or incline acted as such control parameter for technique shifts during classic style roller skiing...

We present a case of acute compartment syndrome (ACS) in an athlete who sustained minimal but repetitive trauma to the thigh during a sporting event. During his evaluation, concern was raised regarding the diagnosis of ACS as a cause of his symptoms. This was confirmed by measuring the intra-compartmental pressures and he subsequently underwent successful emergent fasciotomy, eventually making a complete recovery. ACS is a potential complication of muscular-skeletal injuries from various causes, and our case is unusual as the cause was mild but repetitive trauma in an otherwise healthy athlete...

BACKGROUND: Preparticipation screening for cardiovascular disease in young athletes with electrocardiography is endorsed by the European Society of Cardiology and several major sporting organizations. One of the concerns of the ECG as a screening test in young athletes relates to the potential for variation in interpretation. We investigated the degree of variation in ECG interpretation in athletes and its financial impact among cardiologists of differing experience. METHODS AND RESULTS: Eight cardiologists (4 with experience in screening athletes) each reported 400 ECGs of consecutively screened young athletes according to the 2010 European Society of Cardiology recommendations, Seattle criteria, and refined criteria...

OBJECTIVE: We sought to review studies examining the effect of statins on symptoms of exercise tolerance, markers of muscle injury and activity levels in physical active individuals. BACKGROUND: Statin therapy reduces atherosclerotic cardiovascular disease (CVD) events. Regular physical activity is also associated with reduced CVD events, but statin therapy can produce muscle complaints, which may be more frequent in physically active individuals. We reviewed the literature to determine the effects of statins on symptoms, exercise performance and activity levels in physically active individuals...
