Artistic gymnastics is an physical activity whose content is often used in various forms of exercises and with various intentions (part of treatment after injuries, etc.). Thermography is also increasingly used in sports and exercise science. The purpose of this study was to investigate how different short-term loads affect the temperature of the hand after hanging, supporting and holding a handstand, and swinging in all three positions. These are the three basic positions of artistic gymnastics where the hands are in a different relationship with the body. A secondary goal of the study was to determine if body asymmetries affected post-exercise temperature differences in any way. The measurements took place at the Faculty of Sport, University of Ljubljana. 38 healthy adult students med and women participated. After six loads, images were taken with a thermal imaging camera, the circumference of the palm with and without the thumb was measured, and photos of the hands were taken. Anthropometry was measured with a 3D body scanner, body composition was measured with bioelectrical impedance analysis of the InBody 720 system, and skin thickness was measured with high-frequency ultrasound. The data were edited and processed in ResearchIR, Microsoft Excel, and SPSS programmes. It was found that the hand temperature decreased after all six loads and then increased above the preload temperature. Hand temperature begins to increase more slowly after dynamic loading than after static loading, it increases more and the increased values last longer. 5 minutes after loading, the values are still higher than before loading. Different loads have different effects on the temperature of different parts of the hand, indicating the different roles of the parts of the hand in carrying the load. Asymmetries of the body had no effect on the temperature differences in the hand after loading.
