effects on the independent cardiovascular risk factors, particularly on the Hcy metabolism. The effects of these variables can vary with the unique genetic make-up of an individual. Therefore, the primary objective of this study was to investigate athletic performance and homocysteine levels in relation to the MTHFR C677T mutation and to explore the relationship between this mutation and other cardiac risk factors. The secondary objective was to determine which alleles of the MTHFR C677T polymorphism were associated with high levels of Hcy, total cholesterol, LDL, HDL

Small-sided games (SSGs) are smaller versions of competition ( Halouani et al., 2014 ; Owen et al., 2004 ). For that reason, SSG are frequently used by coaches in training contexts to simultaneously develop fitness and technical/tactical performance ( Clemente et al., 2014 ; Krustrup et al., 2010 ; Little, 2009 ). In order to identify the impact that these games have on players, their effects on acute physiological responses (heart rate, blood lactate concentration or perceived exertion), time-motion profiles (distance covered, speed
This study will attempt to describe the role of existing incentives which have a significant effect on Hungarian sport's performance. The aim of the paper is to understand why a large gap has emerged between successful elite sports and the popular but underperforming spectacular sport. According to the concept of dual competition, in addition to sport results, the analyzed fields also concern competition for resources, particularly for the attention of supporters and sponsors. The methodology of the analysis is fundamentally economic in nature; however, qualitative methods are also given emphasis, as the analyzed topic has specific characteristics. Based on new institutional economics, the study presumes that the behavior of organizations is determined by the decisions of bounded rational individuals, and highlights the significance of the created mechanisms and institutions.

One of the fundamental aims of participating in sport is to maximise athletes’ performance. Research and innovation technology provide an increasing number of information about technical and tactical sport profiles, supporting physical training. In recent years, virtual reality technology (VR) has been often used in many areas of science, finding an application in military, education, mental health, medical therapy and sport.
VR is a visual‐based computer simulation which can reproduce a realistic and controlled environment. Its definition is

Swimming performance depends on the complex relationships between technique, aerobic and anaerobic capacity, as well as psychological factors and power ( Zmijewski et al. 2018 ). Therefore, evaluation of swimmers and training control are fundamental to better understand the interdependence between training variables ( Fernandes and Vilas‐Boas, 2012 ), allowing performance prediction and a follow‐up of training process adaptations ( Anderson et al., 2006 ; Costa et al., 2012 ; Lätt et al., 2010 ).
These data provide relevant information for

A cross-sectional study was conducted to analyze the variations of technical performance and perceived exertion during different SSGs between under-14 and under-16 players. Comparisons between SSG formats within age groups were also executed. The study was conducted 14 weeks after the beginning of the

‐intensity, dynamic, acute cycling exercise on arterial stiffness, but also the relationship with the anaerobic performance of adolescent elite wrestlers.
In the same way as acute resistance exercises, high‐intensity cycling exercises increase short‐term arterial stiffness ( Rakobowchuk et al., 2009 ; Rossow et al., 2010 ). With stiffening of the arterial walls together with increased systolic pressure and reduced diastolic pressure, high pulse pressure (PP) occurs. In healthy individuals, large arteries reduce the amplitude of undulations in the flow and pressure and provide

the main determinants of COD performance in team-sport athletes ( Chaouachi et al., 2012 ; Delaney et al., 2015 ; Gabbett et al., 2008 ; Thomas et al., 2018 ).
Since multiple accelerations and decelerations are present in COD tasks, it is reasonable to assume that the ability to effectively accelerate and achieve higher velocities over short distances is potentially the most important factor contributing to rapid changes in movement direction. Accordingly, previous studies have shown that different speed qualities ( Condello et al., 2013 ; Freitas et al., 2019
Soccer is undoubtedly the world’s most popular sport, played by more than 240 million people as members of 1.4 million teams ( Acar et al., 2009 ). It was reported that the 2014 FIFA World Cup in Brazil attracted a global television audience of 3.2 billion people, with more than one billion people watching the final (FIFA, 2015). Of course, the soccer World Cup provides an opportunity to observe the best teams and players in the world. In addition to the anthropometric, psychological, and physiological research, performance analysis among soccer
