Stressi k\u00e4sitteen\u00e4 voidaan ajatella tarkoittavan tilannetta, jolloin homeostaasia j\u00e4rkytet\u00e4\u00e4n. Stressi voidaan jakaa henkiseen ja fyysiseen sek\u00e4 pitk\u00e4aikaiseen ja lyhytkestoiseen. Ihmisen kokiessa stressi\u00e4, niin henkist\u00e4 tai fyysist\u00e4, tapahtuu hermoston toiminnan johdosta erilaisia fysiologisia muutoksia ihmiskehossa. Reaktio stressiin johtaa esimerkiksi sykkeen kiihtymiseen, verenpaineen kohoamiseen sek\u00e4 erilaisten hormonien erittymiseen, kuten: adrenaliini ja kortisoli. T\u00e4ss\u00e4 tutkimuksessa on tarkoituksena tutkia miten erilaisen harjoitustaustan omaavien henkil\u00f6iden fysiologiset muutokset kevyen henkisen kuormituksen aikana eroavat toisistaan.\r\nTutkimuksessa on mukana kolme koeryhm\u00e4\u00e4, jotka kaikki suorittavat saman testin ja jokaiselta mitataan samat muuttujat: V\u00e4h\u00e4n liikkuva ryhm\u00e4 (N = 16), kest\u00e4vyysurheilijat (N = 8) ja voimaurheilijat (N = 8).

Tutkimus on jaettu kolmeen eri osaan: perustilanne, testi ja palautuminen. N\u00e4iden kolmen eri osa-alueen tuloksia vertaillaan kesken\u00e4\u00e4n sek\u00e4 ryhmien v\u00e4lisi\u00e4 eroja.\r\nRyhm\u00e4t erosivat toisistaan kehonkoostumuksiensa osalta, joka oli odotettavissa. Kest\u00e4vyysurheilijoilla oli alhaisempi rasvaprosentti ja voimaurheilijoilla oli enemm\u00e4n lihasmassaa. Kortisolin osalta l\u00f6ydettiin ero perustasossa v\u00e4h\u00e4n liikkuvien ja urheilijoiden osalta (p<0,05); urheilijoilla oli korkeampi kortisolin taso. Urheilijaryhm\u00e4t my\u00f6s reagoivat\r\neri tavalla kortisolin osalta mitattuna; kest\u00e4vyysurheilijoilla oli kasvava trendi kortisolin osalta ja voimaurheilijoilla laskeva trendi, tosin ilman tilastollista merkitt\u00e4v\u00e4\u00e4 eroa. Ihon s\u00e4hk\u00f6njohtavuus erosi suuresti ryhmien v\u00e4lill\u00e4 ja v\u00e4h\u00e4n liikkuvien ihon s\u00e4hk\u00f6njohtavuus oli korkeammalla tasolla l\u00e4pi testin verrattuna urheilijoihin. Systolinen verenpaine laskee v\u00e4h\u00e4n liikkuvien kohdalla testin ajan ja voimaurheilijoilla systolinen verenpaine on korkeampi palautumisvaiheessa kuin perustilanteessa.\r\nTestihenkil\u00f6t raportoivat kokeneensa henkist\u00e4 stressi\u00e4 tutkimuksen aikana ja mitatut biomarkerit tukivat t\u00e4t\u00e4. Tutkimuksessa l\u00f6ydettiin eroja erilaisten harjoitustaustojen omaavien henkil\u00f6iden osalta. T\u00e4m\u00e4n johdosta voidaan todeta, ett\u00e4 erilainen harjoittelutausta vaikuttaa siihen miten keho reagoi henkiseen stressiin.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.abstract", "value": "Stress has been widely studied and negative effects of stress are considerable in the modern world. Stress can be understood as a situation in which the current state, homeostasis, is being put under the pressure to change. Stress can be divided into physical and psychological stress also stress can be acute or chronic. As human encounters a stressor, whether it is physical or psychological, the nervous system reacts and leads into changes in the biomarkers. For example heart rate is elevated, blood pressure rises and different kind of hormones are secreted like epinephrine and cortisol. In this study an experiment is made were people with different training background go through an acute psychological stress and from all the same biomarkers are measured. Participants are divided to different groups based on their training background.\r\nIn this study there are three groups. Sedentary (N=16), endurance athletes (N=8) and strength athletes (N=8). An acute psychological stress is inflicted with a randomized test consisting of mental arithmetic and Stroop\u2019s color-word test. In the answer sheet of the test there is also a discontinuity so that person will lost the flow and encounter another surprising situation. These results are then compared against the other phases of the test and between the different groups.\r\nBody composition is different between the groups which was expected. Cortisol hormone was on a higher level in the baseline for the athletes compared to sedentary group. Also athletes reacted differently from cortisol point of view; endurance athletes presented an ascendant trend and strength athletes descendent trend although no statistically significant difference was found. Skin\u2019s conductivity was on a higher level, for the sedentary group compared to the athletes (p<0.05), during the whole test. Systolic blood pressure decreases\r\nduring the test for the sedentary group and for the strength athletes the recovery level is higher than the baseline for systolic blood pressure.\r\nTest subjects reported to have experienced psychological stress during the study and this can be seen in the values of the biomarkers. We can then argue that the psychological stress was inflicted to the subjects. We did also see that people with different training background had different kind of reactions to the psychological stress for related biomarkers. We can then conclude that people with different training backgrounds react differently to psychological stress.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Aki Ik\u00e4heimo (akheikah) on 2016-08-11 09:18:18.264223.
