  Our research aimed to determine what temperature changes occur along with the spinal segments during seated exercise and in which direction these temperature values change due to a preventive exercise program. This thesis aims to develop a thermographic analysis procedure to monitor the loads generated in and along the spine of mainly e-athletes and to investigate the effect of a preventive exercise program designed by the research team on the temperature values generated by the load. During our research, we conducted a study with three university students over several months. After an acclimatization period, the research subjects performed e-sport activities in a standardized temperature room while their back temperatures were monitored. The resulting thermograms were analyzed using ImageJ free-use image analysis software. The RGB-type thermograms were converted to 8-bit color depth, and the pixel intensity of the ROI (Range of interest) areas was measured. The following ROI areas were isolated during measurements: neck (C-cervical), back (T-thoracic), lumbar (L-lumbar), and muscle groups to the left (S-sinistrum) and right (D-dextrum) of these areas. Results were obtained at five-minute intervals. Our results showed that the intervention did not produce apparent changes. In two out of three subjects, the cervical section was the hottest, followed by the thoracic and lumbar areas. In general, surfaces to the left of the spinal regions were warmer than surfaces to the right.

  Introduction: The quality of performance is essential both in everyday life and in competition. In sports science (also), we have to think of the man in a complex way as a bio-psycho-social unit. In addition to changes in ECG HR and blood cortisol levels, gastrointestinal tract movements are also associated with stress management (FUKUNAGA et al., 2000) (VIANNA - TRANEL, 2006), which plays a crucial role in determining the quality of performance. Several preclinical trials have formed the basis of our research (SZŰCS et al., 2018).

  Objective: Based on our earlier research and literature reviews, we would like to test and participate in validating a new method that can monitor the effects of stress on humans in real-time, in a non-invasive way, with quantitative results. In addition to GI monitoring, cortisol levels are measured invasively in the subjects, so we hope to obtain complex results.

  Methods: n = 13, athletes, male = 11, female = 2, mean age 22 +/- 1,031 years. Our protocol was 115 minutes, in which we distinguished four stages (rest, stress, latency 1, latency 2). We use two methods to measure stress. One is the blood cortisol level (ELISA), and the other is the MDE Heidelberg Stress Holter (EGG), which is an innovative measurement tool capable of simultaneously examining several parameters (Small Intestine, Colon, Stomach, ECG HR). The VTS DT package was used as a stressor.

  Result: Based on the complex results of the EGG, we can conclude that the Small Intestine, Colon, and Stomach motility, as assessed by the Power Spectrum (PS) Fold Change (FC) calculation, increased together under stress, and then latency decreased together over time. However, the rate of change in cortisol levels showed that most participants adapted the stressor as eustress so that its value decreased linearly.

  Conclusions: Innovative measurement and evaluation methods are well utilized, as they can communicate many measurement data in a valid, real-time, non-invasive way, with a parallel display. These data and results will be used in athlete selection, mental training, elite sports, neuro-biofeedback, and health preservation.
