This study prepared an estimation equation for the evaluation of health status of middle-aged and elderly males and females on the basis of physical fitness tests easily performed at fitness facilities not equipped to conduct medical checkups. The participants were 2,096 males and females aged 30 to 69 years. All participants underwent medical checkups and physical fitness tests, which, based on the judgment of a medical doctor, determined categorization into two groups; namely, a healthy group and an unhealthy group. Multiple discriminant analysis was applied to prepare an estimation equation, and correct discriminant probabilities were used to evaluate the validity of the equation. Physical fitness variables selected for the equations were height, weight, body mass index, percent body fat, grip strength, one leg balance with eyes closed, reaction time, sit-ups, Vo₂max, and age. The correct discriminant probabilities of discriminant functions obtained for males and females were 66.5 % to 76.6 % and 62.7 % to 76.4 %, respectively. This suggested that health status could be evaluated with relatively high accuracy by the estimation equation derived from the physical fitness test. The equation presented in this study as an initial screening test is useful in the practical field of exercise instruction for the promotion and maintenance of health in middle-aged and elderly individuals.

In this study, we analyzed and compared the results of physical fitness and motor ability tests conducted on children enrolled at “A" kindergarten as well as surveys of children's playing. The subjects were 115 boys and girls enrolled in “A" kindergarten between 1995 and 2005. We measured the height, weight, 25-m dash, ball throwing, hanging from a bar, standing broad jump, and standing on one leg. The results were as follows:

1) There were no significant differences between the results of 1995 and 2005 in the overall height or weight of the boys and girls. There were no significant differences among various time periods in the height or weight of the girls and boys separately.

2) In all the boys and girls, there were no differences in the 25-m dash, ball throwing, and hanging from a bar. The children's standing broad jump in 2005 (106.5±18.0 cm) was significantly shorter (p<0.01) than that in 1995 (117.9±16.7 cm). The children's standing on one leg in 2005 (48.5±51.8 sec) was also significantly shorter (p<0.01) than that in 1995 (98.4±97.0 sec).

In conclusion, the results for the standing broad jump and standing on one leg continued to decrease chronologically, and we believe that concrete measures are essential to encourage proper growth and development.

The purpose of this study was to consider the relation between failed shots and rebound balls in basketball. The object of study was the 1^st game of the 200X-X+1 W-League Playoff Finals. In this study, the position coordinates of all players and the ball were calculated by 3-Dimensional photography analysis in which the DLT method was used. The main results were as follows: 1) A significant positive correlation was shown between shot distance and rebound ball distance. That is, the distance of the rebound ball increased in proportion to the short distance; 2) In the 3 point shot, shots from the left side fell on the right side, opposite the shooter, in many cases. On the other hand, shots from the right side fell on both sides. Furthermore, shots from the middle fell on the middle side, which is the same side as the shooter;. 3) A negative correlation tendency was shown in the relation between the distance from the goal and the height at the time possession of the rebound ball was gained; 4) The average and standard deviation of the height of rebound ball acquisition of 2-point shots was 2.07±.056m, and 3-point shots was 1.99±0.39m. Moreover, the highest positions at which possession of the ball was gained were 2.75m and 2.49m.
