We study regularity properties of the subdifferential of proper lower semicontinuous convex functions
in Hilbert spaces. More precisely, we investigate the metric regularity and subregularity, the strong
regularity and subregularity of such a subdifferential. We characterize each of these properties…

This paper analyzes inequality systems with an arbitrary number of proper lower semicontinuous convex
constraint functions and a closed convex constraint subset of a locally convex topological vector space.
More in detail, starting from well-known results on linear systems (with…

The author in his article solves the problems of drug dependence among young people and the problems of sport as a good means against drug dependence. The research sample consisted of 749 pupils of basic and secondary schools in the…

This article provides information on an ongoing research in the field of Sport and Development. The aim of the whole research is to provide knowledge on the role of the football in the personal development of children in the context…

Carried out researches with 28 high skilled gymnasts (15 – main group, 13 – control group) allowed to define the neurofeedback influence on functional condition of the sportswomen in competitive period. Neurofeedback course promotes improvement of rapidity of complex coordinating…

Carried out research showed that changes of complex-coordinated activity, self-estimation of functional condition and cardiointervalographic indexes of the highly skilled gymnasts-women after neurofeedback course depended on dynamics of cerebrum theta-, alpha-rhythm during the neurofeedback sessions and successfulness of the alpha-rhythm…

Maximum gears for youth category riders are limited. As a result, youth category riders are regularly compelled to ride in a high cadence regime. The aim of this study was to investigate if regular work at high cadence regime due…

The hardest part of coaching work is the psychological preparation of athletes and gymnasts, where the aim is to achieve higher performance. Motivation – as the driving force of our actions – has an increased role in preparing the gymnasts,…

The research is devoted to studying of interconnection between successfulness of train to skill of regulation cerebrum bioelectric activity in alpha-band and to revealing of factors (sex, sport skill, general kinematic characteristic of executed motions) providing the distinctive changes of…

As most research about preferences has ignored cognitive development, this study was designed to explore the relation between children's perceptions and preferences for fruit and vegetables and their physical activity. 210 children (100-boys and 110-girls) 9-11 years old recruited via…
