REVIEW
Patrick T Gleason, Jonathan H Kim
The benefits of regular and moderate exercise training on cardiovascular outcomes have been well established. In addition, strenuous exercise training leads to corollary cardiac structural and functional adaptations that are sport-specific and facilitate athletic performance. In this review, the normal physiologic and hemodynamic changes that occur during exercise and the subsequent differential exercise-induced cardiac remodeling patterns that develop will be discussed. Paradoxically, recent data have raised concern about the long-term impact of higher doses of physical activity and exercise on mortality and cardiovascular health outcomes...

Tendons are dense, fibrous connective tissues which carry out the essential physiological role of transmitting mechanical forces from skeletal muscle to bone. From a clinical perspective, tendinopathy is very common, both within the sporting arena and amongst the sedentary population. Studies have shown that light therapy may stimulate tendon healing, and more recently, intense pulsed light (IPL) has attracted attention as a potential treatment modality for tendinopathy; however, its mechanism of action and effect on the tendon cells (tenocytes) is poorly understood...

Impaired cardiorespiratory fitness (CRF) is closely linked to chronic illness and associated with adverse events. The American College of Sports Medicine (ACSM) regression equations (ACSM equations) developed to estimate oxygen uptake have known limitations leading to well-documented overestimation of CRF, especially at higher work rates. Thus, there is a need to explore alternative equations to more accurately predict CRF. We assessed maximal oxygen uptake (VO2 max) obtained directly by open-circuit spirometry in 7,983 apparently healthy subjects who participated in the Fitness Registry and the Importance of Exercise National Database (FRIEND)...

The aim of the present study was to investigate the relationship between green areas and adolescents' body mass index (BMI). This is based on the notion that nature environment is known to have beneficial effects on human health, and that some of the explanation for this is that green areas are especially motivating or suitable as arenas for physical activity. We included 10,527 participants from the Norwegian Youth Study, which was conducted between 2001 and 2004. The participants reported body weight, height, and important potential confounding variables about lifestyle, family situation, and neighbourhood characteristics...

BACKGROUND: Alcohol-related problems at professional sporting events are of increasing concern and alarming reports are often reported in international media. Although alcohol consumption increases the risk for interpersonal violence, it is viewed as a focal element of large football events. Sweden has a long tradition of high public support for strict alcohol-control policies. However, little is known about public opinions on alcohol intoxication and the support for interventions to decrease intoxication at football events...

CONTEXT: Recent changes to postconcussion guidelines indicate that postural-stability assessment may augment traditional neurocognitive testing when making return-to-participation decisions. The Balance Error Scoring System (BESS) has been proposed as 1 measure of balance assessment. A new, freely available software program to accompany the Nintendo Wii Balance Board (WBB) system has recently been developed but has not been tested in concussed patients. OBJECTIVE: To evaluate the feasibility of using the WBB to assess postural stability across 3 time points (baseline and postconcussion days 3 and 7) and to assess concurrent and convergent validity of the WBB with other traditional measures (BESS and Immediate Post-Concussion Assessment and Cognitive Test [ImPACT] battery) of assessing concussion recovery...

CONTEXT: After a concussion, guidelines emphasize that an athlete should be asymptomatic before starting a return-to-play protocol. However, many concussion symptoms are nonspecific and may be present in individuals without concussion. Limited evidence exists regarding the presence of "typical" or preinjury (baseline) symptoms in child and youth athletes. OBJECTIVE: To describe the frequency of symptoms reported at baseline by child and youth athletes and identify how age, sex, history of concussion, and learning factors influence the presence of baseline symptoms...

It has been established that living things are sensitive to extremely low-frequency magnetic fields at vanishingly small intensities, on the order of tens of nT. We hypothesize, as a consequence of this sensitivity, that some fraction of an individual's central nervous system activity can be magnetically detected by nearby individuals. Even if we restrict the information content of such processes to merely simple magnetic cues that are unconsciously received by individuals undergoing close-knit continuing exposure to these cues, it is likely that they will tend to associate these cues with the transmitting individual, no less than would occur if such signals were visual or auditory...

PURPOSE: To describe how athletes with disabilities talk about their experiences of participating in competitive disability sport in South Africa. METHOD: In-depth semi-structured interviews were conducted with 20 athletes with disabilities. Data were analysed via thematic content analysis using an inductive data driven process. RESULTS: Participants described their involvement in competitive sport as a positive experience; they described it as a catalyst for the recasting of identities and reframing an understanding of physical impairment, a context for empowerment and resistance of disablist attitudes, and an arena in which a sense of inclusion and belonging is experienced...

REVIEW
Samuel N Grief
Food allergies are common and seem to be increasing in prevalence. Preventive measures have become far more evident in the public arena (schools, camps, sports venues, and so forth). Evaluation and management of food allergies has evolved such that primary care practitioners may choose to provide initial diagnostic and treatment care or refer to allergists for similar care. Food allergies, once considered incurable, are now being diminished in intensity by new strategies.

Noise exposure and hearing thresholds of indoor hockey officials of the Western States Hockey League were measured to assess the impact of hockey game noise on hearing sensitivity. Twenty-nine hockey officials who officiated the league in an arena in southeastern Wyoming in October, November, and December 2014 participated in the study. Personal noise dosimetry was conducted to determine if officials were exposed to an equivalent sound pressure level greater than 85 dBA. Hearing thresholds were measured before and after hockey games to determine if a 10 dB or greater temporary threshold shift in hearing occurred...

Extensive primary resections or redos may produce significant chest wall defects requiring creative reconstructions in order to avoid reduction of the intrathoracic volume. We describe the successful use of an innovative technique for chest wall reconstruction based on the concept of roof coverage of sport arenas. In fact, titanium plates are anchored to the residual rib stumps along the parasternal and paravertebral lines. The acellular collagen matrix prosthesis was sutured to the free edges of the same titanium plates to create a roof, reproducing the chest wall dome geometric configuration...

Sport injuries are common and costly for the professional athlete, the "weekend warrior," and the community. Acute injuries are treated according to current guidelines with the aim of bringing the athlete back into the arena. These guidelines have not taken into account new scientific results of the inflammatory process following a trauma. The 4 hallmarks of inflammation, namely, pain, swelling, redness, and heat, are results of an adequate inflammatory response with the aim of bringing the affected tissue back to restitution (Latin: restitutio ad integrum)...

Chronic traumatic encephalopathy (CTE) is associated with repetitive mild traumatic brain injury (mTBI) in the context of contact and collision sports, but not all exposed individuals develop this condition. In addition, experiments in animal models in several laboratories have shown that non-transgenic mice do not develop tauopathy after exposure to repetitive mTBI schedules. It is thus reasonable to assume that genetic factors may play an etiological role in the development of CTE. More than 40 mutations in the tau gene are known to confer proneness to aggregation and are thought to cause neurodegenerative diseases including frontotemporal degeneration (FTD)...
