This study aimed to examine the relationships between changes in the center of foot pressure (COP) during the static one leg standing posture and in the balance test on one leg with eyes closed. Subjects consisted of 51 healthy young males (height 173.1±4.3cm, body weight 66.9±5.9kg, and age 21.1±1.5years). Four COP factors were interpreted by applying factor analysis to a correlation matrix consisting of 32 parameters representing the 6 domains of distance, distribution of amplitude, area, velocity, power spectrum, and body sway vector which were used to evaluate COP sway. Unit time sway factor (F1) reflects movement distance (sway velocity) per unit time. Front-back sway factor (F2) and left-right sway factor (F3) reflect the amount of front-back sway and the amount of left-right sway, respectively. The high frequency band power factor (F4) reflects high frequency sway. The COP during the one leg standing posture for 90 sec was divided into three intervals (first interval : 0-30 sec, second interval : 30-60 sec, and third interval : 60-90 sec). F1 and F2 factors during the first interval were significantly higher than during the second and third intervals. The increase in front-back body sway may contribute to the ability to hold postural stability just after the front elevation of the right leg. F3 and F4 factors tended to increase with time. The duration time of balancing on one leg with eyes closed showed insignificant correlation with COP factors (F1-F4) in all intervals. COP factors may not be involved in balancing on one leg with eyes closed.

In order to increase the national presence of Japanese football, it is necessary to first understand the current prevalence. While it has been said that the prevalence of football varies considerably across the country, it has not been examined objectively. This study aimed to analyze the ratio of the number of football players, teams, and referees of each prefecture to the total population based on data published by the Japan Football Association. The total population, the number of football players, teams, referees, and high grade referees differed among each prefecture, and the three prefectures of Akita, Nara, and Wakayama were lower in the ratio of football players and teams to total population than the other prefectures. In addition, the number of teams showed a very high relationship (r=0.91) with the number of players and moderately-high relationships (r=0.70 and 0.73) with the referees. The relationships of the number of referees and high grade referees and of players and the number of both types of referees were moderate(r=0.55-0.68). From the present results, the prevalence of football differs among each prefecture and is lowest in the three prefectures of Akita, Nara, and Wakayama. The number of football referees is closely related to the prevalence of football.
