Abstract
Background: Futsal is a team sport involving intermittent technical actions of high intensity, and high physical (strength) and muscular demands. In this regard, the Tensiomyography (TMG) is a useful and non-invasive tool for the monitoring and assessment of the muscle's contractile capacity. This study aimed to analyze the changes in the...
Research background and hypothesis. Several attempts have been made to understand some modalities of
sport from the point of view of complexity. Most of these studies deal with this phenomenon with regard to the
mechanics of the game itself (in isolation). Nevertheless, some research has been conducted from the perspective
of competition between...

Abstract Scoring in a basketball game is a highly dynamic, non-linear process. NBA teams try to be more and more competitive each season. For instance, they incorporate into their rosters the best players in the world. This and other mechanisms concur to make the scoring process in NBA games exciting and rarely predictable. This paper is to study t...
