The purpose of the study:
The developmental curve of power and agility of boy and girl.
-students from 12 years old to 15 is first made out and the correlation betweenheight and power, height and agility, weight and Power, weight and agility,agility and power is produced.
And then the devision of teaching period for the advancement of their physicalstrangth is the purpose of this study.
Methology :
The power and Agility of 250 students from 12 years old to 15 measured.
The power is measured by sargent jump test and the Agility by shuttle Runtest.
The correlation is produced by Pearson's fo-rmalar (rxy=εxy/Nδxδy) according to these to test.
The results of the study:
1. Reached the following facts as a result of study.
1) The power of the boy-students 12 years old to 15 was developed in almoststraight curve.
The power of students between 14 years old and t5 was remarkably developed.
The Power of girl students from 12 years old to 14 was developed in almoststraight curve aud was backward at 15 years old.
2) The Agility of toy-students from 12 years old 15 was developed almostStraight.
That of girl-students between 12 years old and 13 was developed higher thanusual.
The curve was falling from I5 years old.
3) The correlation of height and power of boy-students is high.
But the correlation of girl studenss from 12 years old one's to 14 year old isusual.
There is no correlation ofter the age of 15 yeari old girls by increlation theirage.
4) The correlation of weight and power of boy-students is high, when thegirl-students is 12 years old and 14 years, the correlation is usual.
5) There is the correlation between height and Agility of boy-students wenthe girl students is 13 years old is low.
6) The correlation between weight and agility of boy-students is usual but thecorrelation of girl students from 13 years old to 14 years old is low.
There is the correlation between Agility and power of boy and girl students.
