Overview
Background: The development of research on exercise physiology in the last several years has allowed to better understand mechanisms affecting exercise performance in athletes. Despite this, the causes of exercise intolerance in athletes are not fully elucidated. The exercise performance is a complex process and regardless of the proper functioning of the cardiovascular system may be subject to significant changes under the influence of nervous system and thermoregulatory mechanisms. The purpose of this work is to assess the relationship between psychomotor performance (sprawnosc psychomotoryczna--SP), core body temperature (Tc) and exercise performance parameters as measured by spiroergometry (cardiopulmonary exercise testing--CPX) and the diagnostic accuracy of neurothermometabolic index (NTMI) as a new marker of exercise performance in athletes. Material and Methods: Forty-four healthy athletes participated in the study. Each of the examined athletes underwent CPX for the assessment of ventilatory parameters (maximal oxygen consumption--V[O.sub.2]max, minute ventilation--VE, ventilatory equivalent for carbon dioxide at anaerobic threshold--VEC[O.sub.2]AT, maximal carbon dioxide output-- VC[O.sub.2] and anaerobic threshold), SP tests (average reaction time to light stimulus, the number of correctly received light stimuli, number of missed light stimuli) before and immediately after CPX. In addition, Tc was continually measured during CPX. Followingly, NTMI was calculated using Tc during the maximum exercise, oxygen consumption at anaerobic threshold and average reaction time to light stimulus as measured after CPX. Results: A significant relationship was found between Tc during the maximum effort in CPX and SP after CPX. A significant relationship between SP before CPX and VEC[O.sub.2]AT during CPX was also confirmed. Psychomotor performance shortly after CPX was also significantly related to VC[O.sub.2]. In addition, NTMI was significantly associated with CPX parameters. Conclusions: The study results confirmed the relevant relationship between SP, Tc during the maximum exercise and ventilatory parameters as measured by CPX in athletes. Neurothermometabolic index is a reliable marker of exercise performance in athletes.

Mimo to przyczyny nietolerancji wysilku fizycznego u sportowcow nie sa w pelni jasne. Wydolnosc fizyczna jest procesem zlozonym i niezaleznie od prawidlowego funkcjonowania ukladu sercowo- naczyniowego moze podlegac istotnym zmianom pod wplywem ukladu nerwowego oraz mechanizmow termoregulacyjnych. Celem niniejszej pracy jest ocena zwiazkow pomiedzy sprawnoscia psychomotoryczna (SP) i temperatura wewnetrzna ciala (core body temperature--Tc) a wybranymi parametrami wydolnosciowymi w tescie spiroergometrycznym (sercowo-plucny test wysilkowy, cardiopulmonary exercise testing-- CPX) oraz wartosci diagnostycznej wskaznika neurotermometabolicznego (neurothermometabolic index--NTMI) jako nowego markera wydolnosci fizycznej u sportowcow. Material i metody: W badaniu uczestniczylo 44 zdrowych sportowcow. U wszystkich przeprowadzono CPX w celu oceny parametrow wentylacyjnych, tj. maksymalnego poboru tlenu przez tkanki (maximum oxygen consumption--V[O.sub.2]max), wentylacji minutowej (minute ventilation--VE), ekwiwalentu wentylacyjnego dla dwutlenku wegla na progu beztlenowym (ventilatory equivalent for carbon dioxide at anaerobic threshold--VECO2AT), wydalania dwutlenku wegla podczas maksymalnego wysilku (maximal carbon dioxide output--VC[O.sub.2]) i progu beztlenowego, ocene SP (sredni czas reakcji zlozonej na bodziec swietlny, liczba poprawnych i blednych odpowiedzi na bodziec swietlny) przed i bezposrednio po CPX oraz pomiar Tc w CPX. Na podstawie uzyskanych wartosci Tc podczas maksymalnego wysilku, wartosci poboru tlenu na progu beztlenowym i sredniego czasu reakcji na bodziec swietlny zmierzonego po CPX wyznaczono NTMI. Wyniki: Stwierdzono istotny zwiazek pomiedzy Tc podczas maksymalnego wysilku a SP oceniana zaraz po zakonczeniu CPX. Potwierdzono istotny zwiazek pomiedzy SP przed CPX a VEC[O.sub.2]AT w CPX. Sprawnosc psychomotoryczna oceniona po zakonczeniu CPX byla istotnie zwiazana z VC[O.sub.2]. Wskaznik neurotermometaboliczny byl istotnie zwiazany z V[O.sub.2]max, VE i VC[O.sub.2] w CPX. Wnioski: Wyniki badan potwierdzily istotny zwiazek pomiedzy SP, obciazeniem termicznym i parametrami wentylacyjnymi w CPX u sportowcow. Wskaznik neurotermometaboliczny jest wartosciowym markerem wydolnosci fizycznej u sportowcow.
