Introdução: A identificação de jovens atletas talentosos no desporto de alto rendimento requer uma abordagem multidisciplinar que considere a complexa cominação de características genéticas, psicológicas, físicas, técnicas e táticas, sendo o rácio 2D:4D uma possível ferramenta adicional. Objetivo: Este estudo visa analisar, através de uma revisão sistemática e meta-análise, as relações entre o rácio 2D:4D e vár...
This study explores the relationship between Career Indicators (CIs) and the retiring age of Portuguese soccer players, focusing on the impact of early career experiences and career discontinuation stages. Data were analyzed from retired Portuguese soccer players registered on a private digital platform, using specific CIs related to different stages of their athletic careers. The analysis involved a two-level ...
Complex training consists of a near maximal strength effort followed by a biomechanically similar explosive exercise. One of many complex training methods that have been proposed is the French Contrast Method. The aim of this study was to analyze the effects of the French Contrast Method on maximal strength and power of young female artistic roller skating athletes with the help of velocity-based training to pr...
The rating of perceived exertion (RPE) is a non-invasive, cost effective, and time efficient strategy to measure training loads. However, data can be collected without following specific procedures and across a range of methods (e.g., different RPE scales and/or different operational questions). Consequently, practitioners working in professional volleyball can use this information in various ways with differen...
Introduction: There has been an abundance of dietary analysis research conducted on adult male soccer players, while studies on youth players are lacking. Furthermore, the daily distribution of energy and macronutrient intake throughout the day has been reported to influence training adaptations, but this is often not considered in the literature. This study aims to quantify daily energy and macronutrient intak...
Background The importance of soccer referees is widely accepted by international soccer organizations and governing bodies, although there is little research summarizing and appraising the literature on soccer referees. The aim of this study was to systematically review the information related to physical demands, nutrition and physiological profiling of soccer referees. Methods Conforming with Preferred Report...

The reactive strength index (RSI) describes the individual's capability to quickly change from an eccentric muscular contraction to a concentric one and can be used to monitor, assess, and reduce the risk of athlete's injury. The purpose of this review is to compare the effectiveness of different training programs on RSI. Electronic searches were conducted in MEDLINE, PubMed, Scopus, SPORTDiscus, and Web of Sci...
