Table 1 shows data that as many as 15 respondents
who have high cholesterol levels are worth 100%
before being given exercise: poco-poco. Cholesterol
blood was measured by using glucometer during the
first meeting with the respondents. Then they was
doing exercise: poco-poco during one month. After
that, researchers measured cholesterol of blood again
post exercise. We found as many as 8 respondents
experienced normal cholesterol levels after being
given exercise: poco-poco (53.3%).
After all data has been collected from all
respondents, an analysis is performed using
computer statistical program tools. The results of the
normality test showed that the data were not
normally distributed so the researchers used the
Wilcoxon sign rank test as in table 2.
Table 2 shows that 15 respondents obtained the
mean cholesterol level of respondents before
exercise: poco-poco was 237.93, with a standard
deviation of 15.476. While the average cholesterol
level after exercise: poco-poco is 213.20, with a
standard deviation of 19.432. Thus there are
differences in mean cholesterol levels in respondents
before and after exercise: poco-poco intervention.
The results of the Wilcoxon Sign Rank Test
statistical test show that the value of p = 0.001 where
(α <0.05), which means that giving exercise: poco-
poco affects cholesterol levels in the elderly.
4 DISCUSSION
Before giving the exercise, poco-poco intervention,
researchers measured cholesterol levels using a
glucometer with results of borderline cholesterol
levels (200-240 mg / dl) and excessive (> 240 mg /
dl). Increased cholesterol levels can be affected by a
decrease in physical activity caused by a decrease in
the musculoskeletal system in carrying out daily
activities with increasing age, limb muscle strength
below is reduced by 40% between the ages of 30-80
years. This disorder causes interference in the form
of swelling, pain, joint stiffness, limited joint
motion, road disturbances, and limited activities
(Padila, 2013). Another cause that triggers an
increase in cholesterol levels in the blood, is diet,
activity and age. Increased fat consumption by 100
mg / day can increase total cholesterol by 2-3 mg/dl
(Suwarsi, 2017).
Older age is also one of the factors that can cause
an increase in cholesterol. Aging age is usually
followed by a decrease in physical activity which
results in decreased numbers of basal metabolites
and increased fat tissue, due to the activity of several
types of hormones (such as insulin, growth hormone,
and androgens). A decrease of hormone causes a
decrease in lean fat while an increase in other
hormone activity increases fat mass. The older a
person, the less the ability or activity of the ldl
receptor, causing low density lipid blood to increase
and accelerate the occurrence of clogged arteries.
Elderly women have cholesterol 2-6 times
greater than men. This is because in elderly women
had a decrease post menopause estrogen. At post
menopause, women experience a decrease in
estrogen and thus have a high risk of heart disease
(Miller, 2017). Increased cholesterol levels in the
elderly in Medan can be caused by various factors,
one of which is age, gender and ethnicity. Elderly
people aged> 60 years are prone to increased
cholesterol and are experienced by all sexes, namely
men and women. Besides that cultural tribes such as
the Bataknese can also affect the elderly
experiencing increased cholesterol where they
prefers to consume foods such as meat which
contains high cholesterol.
After giving exercise poco-poco for four weeks,
the elderly who had high cholesterol levels, obtained
8 elderly (53.3%) included in the normal cholesterol
category and 7 elderly (46.7%) had blood
cholesterol in the borderline category. There are
many factors that cause an increase in cholesterol in
the blood, one of which is a lack of physical activity.
A physical activity result in energy expenditure that
is proportional to muscle work and is associated
with health benefits. The more physical activity
carried out every day, the greater the daily energy
expenditure resulting in a reduction in weight and
fat, this can reduce the amount of cholesterol,
resulting in changes in cholesterol transfer in the
blood (Utami, 2013).
Exercise poco-poco which is carried out
regularly is an initial effort to control and overcome
the increase in blood cholesterol levels in the
elderly. Exercise poco-poco is carried out and taught
twice a week for 4 weeks with duration of 35
minutes for the respondent, and then the cholesterol
level is measured again. This exercise is very easy
for the elderly to do with the movements of the
exercise poco-poco is not difficult and easy to
remember because it consists of complex
movements with moderate difficulty.
In addition, it can be done in groups that allow
for social interaction. The movement used in this
gymnastics is quite accommodating, the song
rhythm is good, and the movements are easy for
everyone, even the old people to follow because they
include movements in every sport such as
