background: grip strength is one of the important criteria in determining the physical fitness of all people, especially athletes. the purpose of this study was to compare the hand-grip strength of young highly trained male athletes of different fields and the effect of some anthropometric indices on it. methods: this cross-sectional study was done on 78 athletes of four fields -wrestling, badm...

Mental toughness in endurance athletes, while an important factor for success, has been scarcely studied. An online survey was used to examine eight mental toughness factors in endurance athletes. The study aim was to determine mental toughness profiles via latent profile analysis in endurance athletes and whether associations exist between the latent profiles and demographics and sports charac...

UNLABELLED Athletic performance is a polygenic trait influenced by both environmental and genetic factors. OBJECTIVE To investigate individually and in combination the association of common gene polymorphisms with athlete status in Ukrainians. METHODS A total of 210 elite Ukrainian athletes (100 endurance-oriented and 110 power-orientated athletes) and 326 controls were genotyped for ACE I/...

Atrial rhythm disturbances, particularly atrial fibrillation (AF), are frequently encountered in trained athletes. P wave dispersion (PWD) is a recent electrocardiographic (ECG) marker that reflects velocity of atrial impulse propagation. However, it remains unknown whether the P wave duration and PWD are different between athletes and sedentary controls. In this study we therefore determined t...

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...

OBJECTIVES We sought to assess the risk of sudden death (SD) in both male and female athletes age 12 to 35 years. BACKGROUND Little is known about the risk of SD in adolescents and young adults engaged in sports. METHODS We did a 21-year prospective cohort study of all young people of the Veneto Region of Italy. From 1979 to 1999, the total population of adolescents and young adults average...

BACKGROUND/AIM Long-term intensive training is associated with distinctive cardiac adaptations which are known as athlete's heart. The aim of this study was to determine whether the use of anabolic androgenic steroids (AAS) could affect echocardiographic parameters of left ventricular (LV) morphology and function in elite strength and endurance athletes. METHODS A total of 20 elite strength a...

BACKGROUND Physical exercise is associated with a decreased risk of cardiovascular disease, which may be partly caused by the effect of exercise on the lipoprotein profile. The most consistent effect of exercise on lipoprotein metabolism is an increase in high-density lipoprotein (HDL). METHODS AND RESULTS Parameters of reverse cholesterol transport (RCT) in 25 endurance-trained male athletes...

This experiment has been designed to evaluate the basal serum BDNF level and memory performance, and also the change in BDNF in response to acute aerobic and anaerobic training in athletes and sedentary groups. Nineteen middle aged elite athletes (45-65 years) who used to be competing at domestic championship for more than 10 years and 20 sedentary subjects participated in this study. Blood sam...

IMPORTANCE To our knowledge, this is the first study to show an association between concussion, cognition, and anatomical structural brain changes across the age spectrum in former National Football League athletes. OBJECTIVE To assess the relationship of hippocampal volume, memory performance, and the influence of concussion history in retired National Football League athletes with and witho...
