In addition to the private sports facilities, the public ones also constitute impor tant bases for local residents doing sport. The purpose of this study was to investigate the consciousness and situation of municipal Gymnasiums users and to examine their geographical situation, especially the relation between the residential distribution of the users and the Gymnasium types. From this study, the following results were obtained:1) "gNearness from residence" hwas most prioritized by the user of either types of municipal Gymnasium.2) From the viewpoint of the Gymnasium type, there seemed to be difference of the residential distribution between standard type Gymnasium users and multiple type Gymnasium users.3) The distance from residence to the used Gymnasium were within about 5km in standard type Gymnasium and within about 10km in multiple type Gymnasium which have certain valueadded facilities.4) Concerning standard type Gymnasium, existence of the river disturbed psychologically users' displacement, and the road arrangement also influenced on it. On the other hand, in the case of multiple type Gymnasium, geographical situation exert less influence on users' displacement and they gather users from almost whole the city.5) Multiple type Gymnasium users feel less further their actual moving distance than standard type Gymnasium users.
This paper presents a model of ski jumping movement after the take-off phase. The flight distance of ski jumping is dependent on the aerodynamic forces. We measure the aerodynamic forces using a scale model of a ski jumper for three flight styles (Normal Style, V Style, Flat V Style) and in addition measure the aerodynamic forces present after the take-off motion. The longest flight distance is achieved with Flat V Style. Considering style transition, we calculate the optimal Changing Time (CT) from Normal Style to V Style or Flat V Style to V Style with computer flight simulation. The relation between the initial angular velocity of a rigid body model of a ski jumper on the sagittal plane and flight distance is clearly explained. In the take-off phase a significant fraction of jumpers initiate upward motion by rotating the upper body. But others complete this movement with small rotation of the upper body to decrease drag. We performe computer simulations for these two cases from takeoff to 0.4sec after take-off. Linear velocity is greatly decreased with the first jumping technique. The second technique however does not suffer from this velocity decrease.
The theory and expression mode of movability of Sportswear are not yet established. The splitting lines derived from the anatomical view points such as muscle antagonism inter-mediated by joints, extensible function of the furrows of skin, sliding function of subcutaneous connective tissues, and dermatome structure, contain the elementary factors to decide directions and form of synchronized movements in the expression of movability of garments in general. Using these factors, we try to refine the principle of the expression of movability of clothes, and show application of this principle to cut patterns, in order to make design base of sportswear with the expression of movability.
In this paper, the difference of paralysis on hitting a baseball ball among various bats is examined by Scheffe's paired comparison that is one of sensory evaluation. To find the cause of the difference of paralysis, the grip acceleration of the bat on hitting a baseball ball is measured, the frequence of the acceleration is analysed by MEM and modal analysis is executed. Further by using sensitivity analysis, FRP bat which the paralysis is not low less than metal bat is produced.
