Evaluation of Centre of Gravity (Cog) of Adult Bengali Population in Relation to Gender and Age

Abstract

This study aims to assess age and sex related variation of center of gravity (CoG) of human body and its association with some anthropometric characteristics. A total of 150 subjects (75 male and 75 female) from the age group of 25 to 55 years were selected at random and they were divided into three age groups: 25-35 years, 36-45 years, and 46-55 years. The whole-body CoG was determined by segmental method. A software was used for computing the location of CoG in the body. The vertical location of CoG was expressed in terms percentage body height taking ground as the reference line and the horizontal location was expressed as the percentage of length of base taking left border of the base as reference line. Results revealed that there was a significant difference in the location of vertical CoG between male and female subjects. No significant difference was noted in horizontal CoG between two sexes. From the results of ANOVA, it was observed that there was no significant difference in the locations of vertical CoG and horizontal CoG among the subjects of different age groups both in cases of males and females. There was no significant correlation between vertical or horizontal CoG and the anthropometric parameters, viz., height, weight, weight, and BMI among the age groups in male and female subjects. It was concluded that the variation of the location of vertical CoG between male and female subjects might not be related to the anthropometric characteristics of the subjects.
