Selected Aspects Of Testing The Positioning Accuracy Of Gnss Receivers Used In Sports And Recreation By Dynamic Measurements, Cezary Specht, Tomasz Szot, Mariusz Specht, Pawel Dabrowski

Baltic Journal of Health and Physical Activity

Satellite navigation systems have been used in professional navigation and geodesy for many years. The past decade has been a time of extending their application to devices also accessible to non-professional users. Sports and recreation is one of the major new areas in which satellite receivers are used. Since device manufacturers do not inform precisely (or at all) about the level of the positioning accuracy provided by such devices, it is necessary to propose a method of its assessment. This paper presents selected aspects of testing receivers in dynamic measurements to determine their accuracy based on international recommendations and standards …

Can Physical Activity Modulate Pain Perception During Ontogenesis?, Maciej Pawlak, Aleksandra Jazdzewska, Katarzyna Leznicka Mar 2022

Can Physical Activity Modulate Pain Perception During Ontogenesis?, Maciej Pawlak, Aleksandra Jazdzewska, Katarzyna Leznicka

Baltic Journal of Health and Physical Activity

The aim of the paper is to emphasise the significance of physical activity as an element directly or indirectly modulating the perception of pain during ontogenesis. Pain is a distinctive sensory sensation and also a subjective criterion of health or disease. In contrast to other modalities (taste, smell, touch), it triggers solely negative emotions and sensations. Pain is a highly individualised sensory phenomenon, involving the physical, cognitive and emotional spheres of human life. Different reactions to pain during ontogeny most often result from the loss of communication skills, a systematic decrease in the functions of all systems and organs, in …
