Based on worldwide experience we should take as an example the best athletes to develop and reach the world elite. Based on this hypothesis, we believe that a detailed analysis of motor mobility during toplevel football matches will support sports t

Sport realization in elite sport is of interest both for the people in the practice (athletes and coaches) and for sport theory. In athletic competitions the discipline 100 m for men has its special place as one of the most popular ones. From there

Football is undoubtedly one of the most famous sport in the world. Monitoring covered distance during training process and official games is well used tool for controlling both fatigue level and sport realization. There is a lot of information for

The main aim of the research is to examine performance and realization of elite 110 m hurdles during major athletics competitions (World Athletics Championships-WAC). We analyze the performance of finalists in major competitions in details (including

The paper presents an approach into the factorization theory of properties of dimension-like type for subsets of a topological space. It is based on a special type of "dimension" of a space on its subspaces which behaves well with respect to factoriz

The paper is devoted to selection theorems for ‘continuous’ set-valued mappings which are not necessarily convex-valued on finite-dimensional subsets of the domain. As a result, we get natural generalizations of the famous Kuratowski–Dugundji e

Every quasi-lower semi-continuous (q.l.s.c.) mapping admits a lower semi-continuous (l.s.c.) selection preserving all important (from the selection point of view) properties of the former mapping. Special-type extensions of l.s.c. mappings are establ

As a rule, most of the classical Michael-type selection theorems are analogues and, in some respects, generalizations of ordinary extension theorems. In this paper we show that the existence of set-valued u.s.c. selections for l.s.c. mappings is not

The paper is devoted to a general factorization theorem for “continuous” set-valued mappings defined on arbitrary topological spaces. This result fits naturally into the selection theory showing that several known selection theorems remain valid
