Takala, Teemu O., Pirjo Nuutila, Juhani Knuuti, Matti Luotolahti, and Hannele Yki-Järvinen. Insulin action on heart and skeletal muscle glucose uptake in weight lifters and endurance athletes. Am. J. Physiol. 276 (Endocrinol. Metab. 39): E706–E711, 1999.—There are no studies comparing myocardial metabolism between enduranceand resistance-trained athletes. We used 2-deoxy-2-[18F]fluoro-Dglucose ...

BACKGROUND The phenotype of individuals with hypertrophic cardiomyopathy (HCM) who exercise regularly is unknown. This study characterized the clinical profile of young athletes with HCM. METHODS AND RESULTS The electrical, structural, and functional cardiac parameters from 106 young (14-35 years) athletes with HCM were compared with 101 sedentary HCM patients. A subset of athletes with HCM e...

AIMS Exercise increases risk of ventricular arrhythmia in subjects with arrhythmogenic right ventricular cardiomyopathy (ARVC). We aimed to investigate the impact of exercise on myocardial function in ARVC subjects. METHODS AND RESULTS We included 110 subjects (age 42 ± 17 years), 65 ARVC patients and 45 mutation-positive family members. Athletes were defined as subjects with ≥4 h vigorous ex...

OBJECTIVE To determine the prevalence of iron deficiency (ID) and iron deficiency anemia (IDA) among a group of female athletes and compare with an age-matched group of female nonathletes. To study lifestyle factors that could play a role in the development of ID and IDA and compare these factors between the groups. DESIGN A controlled clinical trial. SETTING A senior high school for athlet...

Background Intra-articular injuries to the hip in elite athletes represent a source of significant pain and disability. Hip arthroscopic surgery has become the gold standard for the treatment of disorders involving the hip joint. Purpose To examine the incidence of and abnormalities treated with hip arthroscopic surgery as well as the impact on future participation in American football athlet...

In major marathon races such as the 'World Marathon Majors', female and male East African runners particularly from Ethiopia and Kenya are the fastest. However, whether this trend appears for female and male Ethiopians and Kenyans at recreational level runners (i.e. races at national level) and in shorter road races (e.g. in half-marathon races) has not been studied yet. Thus, the aim of the pr...

BACKGROUND In athletes, ECG changes from physiological cardiac remodelling are common but can overlap with findings from a pathological disorder. We compared ECG findings in a group of elite high school athletes to a cohort of adolescents with hypertrophic cardiomyopathy (HCM). METHODS/RESULTS We prospectively performed 15-lead ECGs and echocardiograms in 147 elite high school athletes. Stude...

BACKGROUND The role of endogenous androgens for body composition and physical performance in women athletes is still not elucidated. AIM To examine the serum androgen profile in relation to body composition and physical performance in women Olympic athletes and to compare endocrine variables and body composition to controls. STUDY DESIGN Cross-sectional study, conducted between 2011 and 201...

to explore the abnormalities in iranian athletes' electrocardiogram and find any relation with body fat. 239 international athletes were involved in this cross sectional study. body-fat percentage and resting 12-lead ecgs were recorded from all participants. of 239 participant athletes, 212 were male and 27 female. 60% of participants had sinus bradycardia. a total of 84% of the athletes demons...

BACKGROUND QRS-ST changes in the inferior and lateral ECG leads are frequently observed in athletes. Recent studies have suggested a potential arrhythmogenic significance of these findings in the general population. The aim of our study was to investigate whether QRS-ST changes are markers of cardiac arrest (CA) of unexplained cause or sudden death in athletes. METHODS AND RESULTS In 21 athle...
