that there was a significant difference. Thus, the
alternative hypothesis (Ha) "there is an effect of

4 DISCUSSIONS
The research findings showed that there is a
difference between the average value on VO
2
max
pretest and posttest, i.e. the posttest value > pretest
value. It shows that VO
2
max of the members
increased significantly as indicated by the average of
difference from 29.37 to 33.5. The increase can be
seen if the difference between pretest and posttest is
calculated as 4.13, with a percentage of 14.06%.
Therefore, it can be concluded that the aerobic
training with static bicycles can increase VO
2
max
of the Fitness Center Club House Casa Grande
members as much as 14.06%.
The increasing methods of aerobic endurance can
be used, including continuous training, one of which
using static bicycles. Continuous training is a
training carried out continuously without stopping.
The time used is relatively long, between 30-60
minutes (Suharjana, 2013). Continuous training uses
an intensity of 60 - 80% of the maximum heart rate.
In addition, it happens because it is done repeatedly
and programmed, and it will be patterned on the
cardiovascular endurance system that produces an
adaptation effect on the increase of VO
2
Max.
Furthermore, the research findings showed that
there is a difference between the average value on
BMI pretest and posttest, i.e. the pretest value >
posttest value. According to the differences, it shows
that BMI members experienced a significant
decrease as indicated by the mean difference of
23.97 to 23.42. It can be seen if the difference
between pretest and posttest is calculated 0.547, with
a percentage of 2.28%. Therefore, the aerobic
combination weight training with static bikes can
reduce BMI of Fitness Center Club House Casa
Grande members as much as 2.28%.
The most effective type of training to lose weight
is long-term aerobic training within 20 - 60 minutes
with the frequency of 3-5 times a week, and 65% -
75% of the maximum heart rate (Suharjana 2013).
Finally, the research findings showed that there
is a difference between the average value on body
fat pretest and posttest, i.e. the pretest value >
posttest value. It can be said that the percentage of
the members’ body fat experienced a significant
decrease as indicated the mean difference of 18.44 to
16.92. The decrease can be seen if the difference
between pretest and posttest is calculated as much as
1.52, with a percentage increase of 8.24%.
Therefore, it can be concluded that aerobic
combination weight training with static bicycle can
reduce body fat percentage of Fitness Center Club
House Casa Grande members as much as 8.24%.
These results are obtained because the training
was done continuously. It also needed a lot of
energy to carry out the activities. One of the energy
sources comes from burning fat. This also indicates
that the method can provide good benefits for the
body to help burn calories. Calorie burning shows a
decrease in body fat and weight indirectly. Physical
training, the body can maintain the stability of the
amount of fat and weight so that the body will be
ideal (Irianto, 2004).
5 CONCLUSION
Based on the research findings and the discussions,
it can be concluded that: (1) There is an effect of
aerobic combination weight training on VO
2
max,
