RELATIONSHIP OF BODY MASS INDEX TO THE POWER OF ARMS AND EXPLOSIVE POWER OF LEGS FOR DISPLACED SCHOOLGIRLS OF 9-10 YEARS OF AGE

Abstract

The study aimed at being acquainted with two relationships, Firstly to the explosive power
of legs by linear regression equations in Sargent test and secondly to the power of the arms by linear
regression equations in the test of push-ups. Furthermore, to fit a multiple regression model of the
relationship between the independent variables (the power of the arms and the explosive power of legs)
and the dependent variable (BMI). The participants were 60 female students from the fourth-grade
primary (age mean 9.30 ±0.46-year, height mean 1.32 ± 0.06-meter, weight mean 31.16±8.80-kg, BMI
mean 17.55±3.64). The variables measured included the explosive power of legs (Sargent test) and the
power of arms. Multiple correlation coefficient by the method of all slopes and the test of the normal
distribution of residuals were used to process data statistically.Theoretical or mathematical terms have
not been reached for the validity of the regression model, which has been fitted between the dependent
variable (BMI) and independent variables (explosive power of legs and the power of arms).The
physiological reasons may be what distinguishes performance among children of moderate weight,
overweight and obese, not body composition.
