RESUMO
Kani city, Gifu is yet a typical small local town of 100,000 populations but has Japanese Brazilian and Filipino increased recently and shares 7% of total population that is a foreigner residing town.<br> The foreigner residing towns to be called are facing similar several issues at every place. The working and educational environment for the people as the migrant worker from Central and South America and their health condition which is the most important became worsen.<br> 4 years ago in Kani city, we made a survey for the educational environment of the children of foreigners for 2 years period, which was reported in public and gained favorable evaluation from several sectors.<br> Nowadays we are promoting to assure their social status who live in the local community. They are working as same as Japanese, and sometime to do the job that Japanese would not, but it seems that they are ignored on their treatment in the social life. If they spoil their own health, their life planning may cause a serious problem. Once they dropout, they may not have any chance to recover themselves. This means the “healthy condition” of the local society will be damaged before long. Therefore, we started the foreign nationality citizen's committee where we can maintain not only the individual health but also to be healthy local society from the concept that the foreign residents would not rely on the local society but they act themselves as the citizen and the local residents to participate with the local activities so that they can enjoy their independency, health, pleasure and hope.
RESUMO
1) Tension development during rapidly grip strength exertion of athletes and nonathletes was by Natori's method analyzed.<BR>2) Subjects of athletes were 71 healthy men of 17-26 ages and of non-athletes were 54 healthy men of 17-30 ages. Athletes were 26 high school students of 17-19 ages, 22 physical education college students of 19-21 ages and 23 general adult men of 20-26 ages. High school students were 3 Sumo-men, 4 Judo-men, 6 Kendo-men and 13 Baseball-men. Physical education college students were 6 Handball-men, 9 Rugby-men and 7 Gymnasticsmen. General adult men were 11 Judo-men and 12 Kendo-men. Non athletes were 20 high school students of 17-18 ages, 6 university students of 19-21 ages and 28 general adult men of 21-30 ages.<BR>3) Isometric grip strength manometer were used a new device, to improvement on Smedley's manometer straingauge added.<BR>Tension development were amplifired and recorded by portable Visigraph (Sanei-Sokki Ltd.) with paper-speed of 10cm/sec.<BR>4) In the each case was 3 portions of a whole curve of time course of tension and Pmax.<I>P</I><SUB>1</SUB>, <I>P</I><SUB>2</SUB>; log <I>t</I><SUB>1</SUB>, log <I>t</I><SUB>2</SUB>; tan θ, tan ψ estimated according Natori's method.<BR>5) Except general adults of 26-30 ages of non-athletes were <I>P</I>max. of athletes greater than non-athletes.<BR><I>P</I>max, of a Judo-man of general adult was greatest 68.5kg, and <I>P</I>max. of a high school student of 17 age of non-athlete smallest 35.8kg.<BR>6) Tan θ and tan ψ of athletes were greater than non-athletes.<BR>Tan θ of a Sumo-man of high school student was greatest 0.3628 and tan θ of a Judoman of general adult was greater 0.3500, but tan θ of a high school student of non-athletes was smallest 0.1624.<BR>Tan ψ of a Kendo-man of general adult was greatest 1.6308 and tan ψ of a Sumoman of high school student was greater 1.5769, but tan ψ of a high school student of non-athlete was smallest 0.5278.<BR>7) Muscle strength of non-athletes may well increased to be about 25 age, so that <I>P</I>max. of general adults of non-athletes were greater and of high school students of nonathletes smaller.<BR>But athletes exercised usually for athletic sports, so that <I>P</I>max, and tan θ, tan ψ independent of age was greater than non-athletes, these were an each event varied. <I>P</I>max. of Judo-men of general adults were relative greater and tan θ, tan ψ were greatest. <I>P</I>max. of Handboll-men were greatest but tan θ, tan ψ were relative smaller. <I>P</I>max. of Gymnas-tics-men were relative greater but tan θ, tan ψ were smallest. So that were varied pattern of time course of tension development of hand grip exertion an each event of athletics.
