Active Video Games Versus Traditional Exercises: Energy Expenditure and Blood Lactate Responses.

: The current study aimed to investigate the exercise intensity and exercise characteristics of active video games (AVGs) by measuring various physiological responses, and to test whether AVGs can be used in components of training in sports branches. : Twenty-two male athletes with good aerobic fitness level (age = 20.6 ± 2.

Strength Loss After Eccentric Exercise Is Related to Oxidative Stress but Not Muscle Damage Biomarkers.

: The purpose of this study was to investigate (a) time-dependent changes in muscle damage (MD) biomarkers, oxidative stress (OS) indices, and maximum strength performance; (b) the relationship between changes in maximum strength performance and changes in MD and OS indices; and (c) whether eccentric exercise-induced MD is related to OS. : Twenty-nine male volunteers (age: 22.13 ± 3.

Effects of the Menstrual Cycle on Running Economy: Oxygen Cost Versus Caloric Cost.

: This study investigated the effects of the menstrual cycle on running economy (RE). : Eleven eumenorrheic female athletes (mean age: 21.18 ± 3.

Single coronary artery incidence in 215,140 patients undergoing coronary angiography.

Background: The aim of our study is to determine the incidence of single coronary artery (SCA). SCA is a rarely seen coronary anomaly in which the right coronary artery and the left main coronary artery arise from single aortic sinus. Although SCA has a benign course in most cases and its clinical significance is unknown, in some autopsy studies it was shown to be related to sudden cardiac death.

[Effect of design of standard metallic stents on neointimal hyperplasia and restenosis].

Coronary stents became an integral part of treatment of ischemic heart disease (IHD). Number of percutaneous coronary interventions (PCI) in patients with IHD in Russia constantly growing. At a certain stage of development of interventional cardiology drug eluting stents (DES) were created and became actively used.
