2.1 Subject 
The research subjects used in this study were 20 
mothers selected from Dharmawanita
,  Saronggi 
District. The subjects’ anthropometrics were shown 
in table 1. Each subject filled out the consent letter 
to following this study completely.  
2.2 Procedure 
The procedure was described as follows. First, the 
subjects were measured for anthropometrics, 
including his weight for the initial data. Then, the 
subjects underwent low impact aerobic exercises, 
from warming up to cooling down, 3 meetings in 
one week, for 6 weeks with a duration of 40 minutes 
in each exercise.(Giriwijoyo and Sidik, 2013) to lose 
weight, the minimum duration should not be less 
than 30 minutes. After the treatment is finished, the 
subjects were weighed again to find out the final 
weight to be used as the final data and after that the 
data were analyzed.   
2.3  Data Analysis 
After the data is obtained, the data were analyzed.  
The data analysis in this study was done using the t-
test statistical method to determine differences in 
body weight before and after being given treatment 
for women.  The mean and standard deviation 
should also be calculated prior to t-test, so that later 
it will be easier to analyze different test data.   
3 RESULT 
The research data were obtained from the results of 
the pre-test and post-test body weight of the research 
subjects. They were then analyzed. In the table 2, it 
can be seen that the average body weight is 59.5 ± 
3.98. The ideal body weight with an average subject 
height 153.65 ± 3.6, obtained an average of 53.55 ± 
3.9, where the period the body of the subject has an 
overweight of 59.4 kg. If it is associated with a body 
mass index table with an average height of 153, 
normal weight should be in the range of 44-54 
(Giriwijoyo and Sidik, 2013). After a low impact 
aerobic exercise, the subjects’ body weights were 58 
kg in average, so there was a decrease of 1.5 kg.

Based on table 2, the average numbers of body 
weight were 59.5 ± 3.98 for the pre-test and 58 ± 
2.79 for the post-test. After being tested using the t-
test, it can be said to have a significant relationship. 
4 DISCUSSION 
From the results of statistical calculations using the 
t-test, the findings showed that there were significant 
differences between before and after being given 
low impact aerobic exercise treatment. In 
conclusion, it can be said that low impact aerobic 
exercise has a significant influence on weight loss 
for the subjects. Although the quantity is not 
maximal, but there is a significant decrease. These 
findings is in line with the research conducted by 
(Wu, Tu, Hsu, and Tsao, 2016) that low impact 
aerobic exercise can significantly decrease a 
percentage of body fat. 
After doing routine activities, a person's weight 
will decrease because doing aerobics is a good way 
to burn calories and fat. Many muscles are mobilized 
from the top and bottom of the body. The more 
muscle you exert, the more calories you burn (Lynne 
Brick, 2001). 
It can be said that there is a relationship between 
aerobic exercise and weight. If someone does 
aerobic exercise regularly, the person will 
experience weight loss and will be
 free from disease. 
Finally, their quality of life will be better.  This 
opinion is supported by (Brick, 2002), saying that 
aerobic exercise is one of
  the best ways to reduce 
one's weight, to develop muscle health, and to 
improve a better quality of life. The same thing was 
conveyed by (Denise, 2008), that 4 weeks of 
functional trainings would result in increased 
functional levels in older adults.
