In addition, Jhon and Eric (2008): By doing
physical activity, it will happen oxygen-filled blood
supply into the brain. This will stimulate the growth
of new cells in the brain so that the brain cells will
multiply and with the number of new cells will form
new neurons that have more synapses that will
eventually make the brain capable of receiving more
impulse and able to store longer and faster to be
reappeared when asked. In addition to the growth of
many new cells, another impact is to grow and
develop a type of protein in the brain that is called
the Brain Derived Neurotropic Factor (BDNF). The
function of BDNF itself is to build and maintain the
cells in the brain of the Hippocampus, the part of the
brain associated with the brain's ability to receive
and store information obtained, in other words the
hippocampus is related to the quality of the brain's
memory work. With the abundance of BDNF in the
hippocampus, the memory capacity of the brain gets
better and last longer.
So it is clear that physical activity can affect
memory performance. Conversely, if the lack of
movement in this case does not do physical activity
due to unhealthy lifestyles, will cause a decrease in
memory performance of a person. From some of
these findings, it can be raised a problem that the
high demands of work that require good body
condition should be supported by a healthy lifestyle
that is by doing physical activity one of them is by
cycling. This problem is raised because there is no
empirical data concerning research aimed at people
already working, requiring memory work demands
especially in the productive age between the ages of
20 to 35 years.
Lately there has been a b2w community called
Bike to Work, which raised the popularity of
bicycles as motor vehicle replacement vehicles to go
to the office. There is an interesting phenomenon
that can be studied in this bike to work community.
For office workers, cycling not only makes life
healthier, but it is also believed to help to refresh
one's memory. This is in accordance with that
disclosed by Holmann in tieneke (2008) in his
research revealed, that the youth (students) who
exercise cycling is known to have blood flow to the
brain increased 30%. The increased blood flow in
the brain will trigger the brain to release some
proteins, including a kind of brain-growing protein
called Brain Derived Neurotropic Factor (BDNF)
that causes the growth of new nerve cells in the
working hippocampus saves memory for a long time
and minimizes the occurrence of concussions.
Given this BDNF growth, the cycling students are
relatively faster and better at completing the test
than the students who are not cycling.
The human memory system has two forms; short
term memory and long term memory. Short-term
memory has a role as a place to store memories that
are only temporary or in other words that
information can be remembered after a few minutes
of noticing and memorizing. While Long-term
memory, is part of the human brain that has the task
of storing memory for a long period of time. Long-
term memory is considered necessary for someone,
this is because it will be stored in the brain and will
make someone remember it with the old and make
the process of motion that automation.
Based on the above explanation, the focus of
research conducted is to describe the effect of
cycling activity on the ability of long term memory
for the perpetrators.
2 METHODS
The method used in this research was ex-post facto
study in intact-group comparison. The method
focuses more on comparative study. The aim of ex
post facto research is to see the effect of certain
phenomena and examine the causal effect of the data
after the event has been completed.
