Thermal comfort during sport activity

V okviru diplomskega dela je bila izvedena raziskava toplotno-fiziološkega udobja testne osebe pri nošenju športnih majic pri športni aktivnosti. Za ta namen je bil raziskan vpliv treh različnih športnih majic na toplotno udobje testne osebe v toplem okolju, in sicer bombažne majice in dveh podobnih modelov športnih majic, izdelanih iz outlast pletenine. Raziskava je bila izvedena pri umetno ustvarjenih klimatskih pogojih v računalniško vodeni klima komori, tj. pri temperaturi zraka: 25 °C, 29 °C in 33 °C ter konstantni relativni zračni vlažnosti 50 % in hitrosti gibanju zraka 0,5 ms-1. Toplotno udobje testne osebe je bilo določeno na podlagi eksperimentalne metode merjenja sprememb fizioloških veličin, kot so: srednja temperatura kože, srčna frekvenca in vlažnost kože ter količine izhlapelega znoja. Poleg neposrednega merjenja spremembe fizioloških parametrov je bilo izvedeno tudi vrednotenje subjektivnega občutka udobja testne osebe pri nošenju analiziranih športnih majic. Za ta namen je bil glede na zahteve standarda oblikovan vprašalnik, na katerega je testna oseba odgovarjala pred, med in po raziskavi. Na podlagi dobljenih rezultatov raziskave je ugotovljeno, da vrsta in lastnosti oblačila, v raziskanem primeru športne majice, neposredno vpliva na toplotno počutje testne osebe pri športni aktivnosti.In this thesis research of thermo-physiological comfort on the test subjects wearing different sport shirts at sports activities was made. Clothing, used for the purpose of this research, was made out of outlast knitwear and conventional knitwear for sport shirts manufacturing. The survey was conducted in various man-made climate conditions in computerized climate chamber at an air temperature of 25° C, 29° C and 33° C. Thermal comfort of the user has been established on the basis of the experimental method of measuring changes in human physiological values, such as: mean skin temperature, heart rate, skin moisture and the amount of evaporated sweat. The research was based on the evaluation of a subjective feeling of comfort in relation to the standard requirements. For this purpose, the evaluation scale in the form of questionnaires was used, in which the test person answered before, during and after the study. Based on the giving results, it is discovered that individuals in sport activities experience heat and physical overload. Climate conditions have a significant impact on humans and clothing that are in the same thermal environment
