Handstand on parallel bars: temperature differences of palms after static and dynamic load

The temperature of palms and their differences after different loading have not been well studied. Our research question was how palm temperature differs in human hands after different loads (handstand and swinging in handstand) for 30 seconds on low parallel bars. A high quality thermal imaging camera was used to measure 38 students from the University of Ljubljana, Faculty of sport. Palm temperatures were measured before the load was applied, immediately after load and every 30 seconds for a period of 5 minutes after the load. Each hand was divided into 9 different Regions of Interest (ROIs). Mean (XA), standard deviation (SD), maximum and minimum, and number of pixels were calculated. According to our results, there was no difference between the left and right hands. The temperature immediately after loading decreased significantly in both loads and then increased above the level as before loading. After static loading, the temperature decrease is smaller and then increases faster than after dynamic loading. For both loads, the temperature is higher 5 minutes after the load than before the load. We need to further investigate how long it takes for the hand temperature to reach the pre-load temperature Temperature dlani in njihove razlike po različnih obremenitvah niso dobro raziskane. Naše raziskovalno vprašanje je bilo, kako se razlikuje temperatura dlani v človeških rokah po različnih obremenitvah (stoji na rokah in kolebih v stoji na rokah) 30 sekund na nizki bradlji. S kakovostno termovizijsko kamero smo izmerili 38 študentov Fakultete za šport Univerze v Ljubljani. Temperature dlani so bile izmerjene pred obremenitvijo, takoj po obremenitvi in vsakih 30 sekund v obdobju 5 minut po obremenitvi. Vsaka dlan je bila razdeljena na 9 različnih območij zanimanja (ROI). Izračunani so bili povprečje (XA), standardni odklon (SD), maksimum in minimum ter število slikovnih pik. Glede na naše rezultate ni bilo razlike med levo in desno roko. Temperatura takoj po obremenitvi se je pri obeh obremenitvah bistveno znižala in nato narasla nad nivo kot pred obremenitvijo. Po statični obremenitvi je padec temperature manjši in nato narašča hitreje kot po dinamični obremenitvi. Pri obeh obremenitvah je temperatura 5 minut po obremenitvi še vedno višja kot pred obremenitvijo. Nadaljnje raziskave so potrebne, da bi ugotovili, kako dolgo traja, da temperatura dlani doseže temperaturo pred obremenitvijo.
