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.
