calisthenics, stretching, sit-ups, pushups and medicine ball exercise with moderate intensity (60-
70%). Mean and standard deviation were calculated for LDL for each group. . ‘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. Statistical significance was set to priority at 0.05 levels.

To find out the significant difference between pre test and post test on low density
lipoprotein ‘t’ ratio was employed and the level of significance was set at 0.05. The experimental
group on Low Density lipoprotein pre test value was 125.10 and post test value was 118.20
respectively. The mean difference value was 6.9 and low density lipoprotein obtained ‘t’ ratio
15.92 was greater than the table value 2.292. Thus, the results obtained proved that the
intervention namely physical exercise on Low Density Lipoprotein produced significantly
improvement. The control group on low density lipoprotein pre test value was 125.40 and post test
value was 126.00 respectively. The mean difference value was 0.6 and low density lipoprotein
obtained ‘t’ ratio was 1.96 and is lesser than table value of 2.262. Thus, the results of control
group did not show any significant changes on Low density lipoprotein.

CONCLUSION
The result of this study indicates that the level of low density lipoprotein increased
significantly over the twelve weeks training period of physical exercise. However, the difference
among the pre and post test of experimental group are significant. The control group did not show
any significant changes on low density lipoprotein.
