Psychophysiological Effects of Performing the Sport in Out of Ordinary Life

The aim of this study was to evaluate the pyschophysiological effects of sport which was performed in out of the ordinary student life. We chose the skiing as such type of the sport, and determined the changes in body weight, blood pressure, heart rate and degree of psychological stress during the staying the ski ground for three days. The 21 males (19.5+-3.7yrs) and 18 females (19.1+-0.7yrs) students were participated in this study. These students had a lower physical fitness relatively as compared with the other students of same age. The body weight (male students) were decreased in first day, and it was not recovered in following third day. These changes in body weight may be due to the more rapid increment of their physical activities for three days than that of usual daily life. The changes of mean heart rates during the skiing revealed that this kind of sport was performed in high intensity of physical activity for these students. However, skiing may not be contributed to the mental stressor negatively for them because of the maintenance of low blood pressure in resting states during three days. Moreover, we evaluated the degree of psychological stress and changes of mood state by using questionnaire chart. From these results, not only the decrement of psychological stress but also increasing the quality of life were found during the three days. In addition, increased scores of mood state which shows the feeling of \u22pleasantation\u22, \u22relaxation\u22 and \u22satisfaction\u22 were also found after skiing
