Abstract:
Fish smoking is one of fish preservation methods. Fish smoking process use corn cobs as fuel.
Continuous smoke exposure and inhalation can cause a decrease in lung function in workers. One of
the activities that can be done to improve respiratory efficiency is practicing modified low impact
aerobic exercise. The aim of the study was to analyze the effect of the implementation of modified
low impact aerobic exercise. The research was a quantitative research with quasi-experimental
method using two-factor completely randomized design. The experiment was conducted by
categorizing the sample into four groups: group I was treated by 1-week modified low impact
aerobic exercises, group II acted as the control for group I, group III was treated by 2-week modified
low impact aerobic exercises, and group IV acted as the control for group III. Each group consisted
of 24 samples. The levels of respiratory efficiency were measured before and after 1-week treatment
for Group I and II and 2-week treatment for Group III and IV. The result shows that the
measurement of Vital Capacity FEV 1 for group 1 that conducted 1-week low impact aerobic
exercises showed an increase of 9.63% and group 2 that conducted 2-week low impact aerobic
exercises showed an increase of 9.25%. While the measurement of Vital Capacity FEV1/FVC for
group 1 that conducted 1-week low impact aerobic exercises showed an increase of 5.75% and group
2 that conducted 2-week low impact aerobic exercises showed an increase of 17.5%. The result of
General Linear Model shows that there is a correlation between the exercise using modified low
impact aerobics to the levels of respiratory efficiency with p-value 0,003 (?<0,05).
