A Study Of Body Composition Changes Before And After Performing Muslim Prayer In Female Subjects

by Robiyanti AdollahSemester 2, 2004/2005This thesis presents the study of body composition changes in female Muslim before and after performing Zuhur prayer. There is a total sample of 28 female subjects that volunteered participated in this study. The age is in between 18 to 35 years old. The mean of age in this group study is 21.4 ± 3.474.
There are two types of bioimpedance method used in this study; single frequency and multiple-frequency measurements. This is in vivo technique where a constant current of less than 1 mA at a single frequency of 50 KHz (BIA Model 450) and Multiple frequencies at range 5 to 1000 KHz (Xitrons Hydra ECF/ICF Model 4200) is applied through the human body to measure the body composition.
All statistical analysis is performed by SPPS version 10. There are two main results analysis; single frequency and multiple-frequency. Test of Analysis of Variance (ANOVA) are applied to the data to identify the significant value between the groups of data before and after prayer.
In single frequency, Analysis of Variance shows that the changes in body composition before and after prayer are not significant (the p value is greater than 0.05) and this is indicates that there is no significant difference between body compositions before prayer and after performs the prayer. In single frequency, the group of missed prayer and no missed prayer in a week were evaluated using ANOVA. Two components of body composition show the significant value (p< 0.05) and the two component of the body composition that shows the significant value is fat mass and body lean mass. This results indicate that the fat mass and body lean mass may were influenced by the activity of prayer that the subjects perform daily or weekly. Other components do not show the significant value in the analysis.
For the multi-frequency, the graphs of Resistance versus frequency, Impedance versus frequency, phase angle versus frequency and cole-cole plot (reactance versus resistance) are plotted to shows the changes of body composition with the increasing of the frequency.
