PRIMARY OBJECTIVE To examine the possibility that athletes with multiple concussions show cumulative effects of injury. METHODS AND PROCEDURES Amateur athletes with a history of three or more concussions were carefully matched (gender, age, education and sport) with athletes with no prior concussions. All completed a computerized neuropsychological test battery at preseason (ImPACT) and then ...

D ifferentiating between young, athletic patients with hypertrophic cardiomyopathy (HCM) and elite athletes sometimes can be problematic. Left ventricular hypertrophy is seen mainly in athletes participating in endurance sports. A conflict exists with regard to strength athletes. Recent investigations suggest that strength athletes who use anabolic steroids have increased left ventricular hyper...

The academic performance of students in grades 9-12 who did or did not participate in high school sports in Kansas during the 2008-2009 school year was analyzed. In addition to overall comparisons between athletes and non-athletes on GPAs, graduation rates, number of dropouts, ACT test scores, and state assessments, some gender, ethnicity, and grade comparisons were made. High school athletes e...

The purpose of this research was to utilize the concept of hubris to frame a discussion of differences between collegiate athletes and collegiate non-athletes. Surveys were distributed to a collegiate student population that included both athletes and non-athletes and included questions that served as proxies for varying dimensions of hubris, such as perceptions of campus police (conventional a...

Long-term training leads experts to develop a focused and efficient organization of task-related neural networks. "Neural efficiency" hypothesis posits that neural activity is reduced in experts. Here we tested the following working hypotheses: compared to non-athletes, athletes showed lower cortical activation in task-sensitive brain areas during the processing of sports related and sports unr...

BACKGROUND This study is a cross sectional analysis, aiming to evaluate if atopy is as a risk factor for exercise induced bronchoconstriction (EIB) among Tunisian athletes. METHODS Atopy was defined by a skin prick test result and EIB was defined as a decrease of at least 15% in forced expiratory volume in one second (FEV1) after 8-min running at 80-85% HRmaxTheo. The study population was com...

BACKGROUND AND OBJECTIVE For athletes, the main purpose of nutrition is to ensure the compensation of increased energy consumption and the need for nutrients in the athlete's body, thereby enabling maximum adaptation to physical loads. The aim of this study was to determine the habits of highly trained endurance athletes depending on sports type, sex and age in order to improve the planning and...

AIM To describe the electrocardiographic (ECG) and echocardiographic manifestations of the paediatric athlete's heart, and examine the impact of age, race and sex on cardiac remodelling responses to competitive sport. DESIGN Systematic review with meta-analysis. DATA SOURCES Six electronic databases were searched to May 2016: MEDLINE, PubMed, EMBASE, Web of Science, CINAHL and SPORTDiscus. ...

purpose many factors influence athletes’ performance including anthropometric, physiological and environmental parameters. high altitude is characterized by adverse environmental conditions that are not found at sea level. we investigated the influence of some anthropometric and physiological factors on performance in the context of the mount cameroon race of hope. methods age, height, weight, ...
