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

Abstract

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 30-second loads (handstand and swinging in handstand) 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 investigation how long it takes for the hand temperature to reach the pre-load temperature.
