Projektcím: A sportolók felkészítésénél jelentkező stressz hatás mélyrehatóbb vizsgálatához egy metodika és mérőrendszer kidolgozása a gasztrointesztinális motilitás (EGIG) és a kardiális változások alapján. Kedvezményezett: Szegedi Tudományegyetem Web: www.u-szeged.hu PIAC_13-1-2013-0201 Dr. Balogh László Dr. Mikulán Rita Dr. Molnár Andor Hajdúné dr. Petrovszki Zita As Selye describes, stressors can be perceived by an individual as positive or negative. Stressors perceived as being disruptive or upsetting can lead to negative feelings, or distress, while those stressors perceived as being motivating or enjoyable can lead to positive feelings, or eustress. Hull drive theory that proposes a linear relationship between arousal and performance where as arousal increases so does the quality of performance. As stress increases, so does performance, but only to a certain point, after which performance begins to decline. This relationship is known as the Yerkes-Dodson Law. Hanin believes that each athlete has one’s own optimal anxiety level and zones of intensity which are always individual and could be either low, or moderate, or even high Paper-and-pencil test, the most common type of tests, however, the small number of new research that may provide an opportunity to measure arousal in an objective manner. EGG examination. An electrogastrogram is similar to an EKG of the heart. It is a recording of the electrical signals that travel through the muscles of the stomach and control the muscles' contraction. Innovation: EGIG investigation procedure Stress – anxiety – objective measurement of zone We would like to develop a new device, based on earlier preclinical studies and research to measure the optimal zone (stress and anxiety level). How is EGIG done? EGIG is a non-invasive test, relatively inexpensive, and easy to perform. Electrodes are placed cutaniously on the abdominal skin over the GI. While the patient is lying down relaxing, the electrodes record the electrical activity of the GI. 3D human gastroenterogramm. On a vertical axis a spectrum of signal from GI smooth muscle in µV. Frequency ranges from left to right: large intestine, stomach, ileum, jejunum, duodenum Application areas Eating Human diagnostics The electrodes of EGIG sense the myoelectrical signals coming from the GI's muscles, and the signals are recorded on a computer for analysis. It is based that different organs of a GI tract give different slow wave frequency. The EGG Diagnostics is possible to capture normal, or different activities of GI organs. The EGG diagnostic procedure can provide allround assistance in the area of nutritional science in a way that makes it objectively examined was lifted each gastric bodies (primarily the stomach) in response to nutrient intake. The most common answers: • Normal operation • early sense of fullness • distension / bloating • nausea Research The EGIG diagnosis is preferably matched many research area of different diseases. Such areas are psychological and physical stress, pathological changes of gastric area (Crohn's, colitis etc) in preclinical and clinical research. Pilot Study young adult athletes (n=18) empty stomach in the supine position EGIG Examination time (min) 0 20 1. period 40 2. period sound stimulus EGIG system: Experimetria (Hungary) University of Szeged Juhász Gyula Faculty of Education Institute of Physical Education and Sports Science 2014 july Results evaluation of the data by Adware Research Kft mean complete mean for 20 min max between 20-30 mean from 30 min Mean of cycles per minute (CPM) CPM CPM CPM CPM complete stomach small intestine com colon . During the preliminary tests clear differences were detected between 20 minutes and 20 to 30 minutes and the results after 30 minutes. Regarding the different phases the largest differences can be detected due to sound stimuli in the colon.
