A Study of Body Mass Index in Relation to Motor Fitness Components of School Going Children Involved in Physical Activities

Abstract

The purpose of study was to evaluate and compare the motor fitness in relation to Body Mass Index of school going children involved in physical activities.. One hundred school going male children of 9th and 10th grade were selected to serve as subjects for this study. The researcher divided the entire 100 sample into three groups. i.e. low BMI (N=25) , middle BMI (N=50) and High BMI (N=25) groups, which were compare with each other. All the subjects were tested on Chin ups, Vertical Jump, Shuttle Run, Sit and Reach and BMI (Body Mass Index)., In order to find out the significance of differences between low BMI- high BMI, and middle BMI- high BMI of school going male children, means, standard deviations, quartile deviation (Q1 and Q3) and t-ratio were computed. The results of the study revealed that the significant difference was not found between Low BMI group- High BMI group in their vertical jump, flexibility, chin-ups components of motor fitness. Low BMI group children were more superior on muscular strength, speed, and agility and similar on flexibility compare to high BMI group children. Low BMI group was also superior on speed and agility components of motor fitness than middle BMI group children and was similar in other component of fitness. Where as, middle BMI group children were more superior on muscular strength, speed, and agility and similar on vertical jump and flexibility components of fitness in comparison of high BMI group children.
