EFFECT OF PHYSICAL EXERCISES ON LOW DENSITY LIPOPROTEIN
OF COLLEGE WOMEN STUDENTS
Dr. R. Kalaiarasi, Director of Physical Education, Arulmigu Palani Andavar Arts College for
Women, Palani – 624 615, TamilNadu.

ABSTRACT
The purpose of the study is to find out the effect of physical exercises on low density
lipoprotein of college women students. To achieve this purpose of the study, forty college women
students of Arulmigu Palani Andavar Arts College for Women, Palani, Tamilnadu, were selected
as subjects, and their age was between eighteen to twenty five years. The selected forty students
were divided into two equal groups, the experimental group – 1 (n = 20) underwent physical
exercise,(n= 20, CP) served as control participants. In the study, physical exercises were adopted
as independent variable. Low density lipoprotein was chosen as a dependent variable. It was
measured by blood sampling method , the unit of measurement was in milligrams. The pre and
post test random group design was used. ‘t’ test was used to find out the significance difference
between the mean of pre and post test of each group with respect to Low density lipoprotein.
Keywords: 1. Physical Exercise, 2. Low density lipoprotein

INTRODUCTION:
The beneficial effects of physical activity typically include reductions in cholesterol level
and body weight (USDHHS, 2004). Systematic physical activity develops and maintains physical
fitness and overall health. It is often practiced to strengthen muscles and the cardiovascular
system, and to improve athletic skills. Frequent and regular physical exercise boosts the immune
system, and helps prevent diseases affluence such as heart disease, cardiovascular disease (Ronald
et al., 2004). An adaptation of the human body to physical exercise can improve the health of
internal systems and the efficiency of external movements.LDL Cholesterol is the primary
transport carrier of cholesterol in the circulation. About 50 - 60% cholesterol is delivered to the
cells by LDL-C. Evidence suggests that LDL-C may directly contribute the cellular alterations of
the inner walls of the arteries which may ultimately lead to the development of atherosclerotic
plaque (Scann, 1978). Thus, LDL-C is proposed to be more highly associated with CHD than total
cholesterol. Recent overview have indicated that a 1% reduction in a person’s total serum
cholesterol level yields a 2 to 3% reduction in the risk of coronary heart disease (Manson et al.,
1992).Elevated levels of LDL cholesterol have been strongly associated with an increased risk of
heart attack and stroke (Yataco et al., 1997). LDL-C tends to stick the lining of the blood vessels,
which helps to stimulate atherosclerosis. This study has attempted to investigate the twelve weeks
of physical exercise on low density lipoprotein of college women students.

MATERIALS AMD METHODS
To facilitate the study, forty college women students from Arulmigu Palani Andvar Arts
College for Women, Palani, Tamilnadu, were selected as subjects at random and their age was
between eighteen to twenty five years. They were divided into two equal groups namely
experimental Group and Control Group did not involve in any training. The pre test was taken
from the subjects before administering the training. The subjects were involved with their
respective training for a period of twelve weeks. At the end of the training, the post test was taken.
Low density lipoprotein was chosen as a criterion variable. It was measured by Blood Sampling
Method; the unit of measurement was in mgdl-1. The experimental group initially performed
thorough warming up exercises. After that group I performed the following exercises such as
