Abstract

The aim of this study is as follows. We implemented an exercise using a Large-sized ball as the introduction to a class for women university students. The aim of this study is to make it clear how the psychological state changes before and after the exercise, and how it changes according to the time of the exercise: before or after noon. The subjects were 84 of women students of J-University who took the course of “Lifelong sports practice” which is one of the related subjects of sports and exercise in J-University. An exercise using a Large-sized ball was implemented for 30 minutes as the introduction to the class, and the change in psychological state was measured as the Two-dimensional Mood Scale. Also, on the voluntary base, questionnaire investigation was performed in which students were asked to describe their feeling in free format. As a result, it was found that degree of pleasure level and arousal level significantly increased after the exercise irrespective of the time of implementation. The change in feeling before and after the exercise, for both AM group and PM group, was as follows. After the exercise a trend was seen that the two-dimensional-coordinate shifted from “the area of apathy, dysphoria” to the “activity oriented area”. As for the description of the feeling before and after the exercise, much of it was about the feeling of unpleasantness and constipation before the exercise. After the exercise, however, much of it was about pleasantness. It was observed that by implementing an exercise using a Large-sized ball as the introduction to a class for women university students, the degree of pleasure level and arousal level increase irrespective of the time of implementation; improvement of the psychological state is suggested toward the activity oriented state.
