PENGARUH RENANG INTENSITAS RENDAH (LOW INTENSITY SWIMMING) TERHADAP KAPASITAS VITAL PARU
Abstract: Pulmonary disease
was ranked on the third place of the most common disease with the prevalence of
17%. Pulmonary disease can lead to a decrease in vital capacity of the lungs.
Vital capacity of the lungs are also affected by other factors such as body mass
index, gender, age, as well as physical activity. Several previous studies have
shown that swimming activity can increase lung capacity and the ability of
respiration as well.
Based on these results, the aim of this study was to determine the effect
of swimming on lung vital capacity changes at male medical students.
This study using pre-experimental with pre and post test design and
twenty male of medical students (mean age 19.5±1.5 yr;bmi 21.9±3.4kg/m²) were
selected by consecutive sampling technique and adjusted to inclusion and
exclusion criteria. Spirometry inspection, chest radiographs through X-ray and
ECG was also done interpreted by medical specialists to ensure that the samples
did not have a history of cardiac as well as pulmonary disease.
Swimming was conducted for 2 weeks with a frequency of 1 time a week for
30 minutes. The method of training using repetition interval extensive by
dividing the volume of exercises into 5 series. Each series of exercises
performed for 6 minutes easy swimming in training zone of 70%-85% of MEHR
(Maximum Exercises Heart Rate) with rest periods between series for 15 minutes.
Measurements of lung vital capacity was done twice, ie prior and post of
intervention and the data would be statistically analyzed by paired t-test
method.
The result showed that there is a significant difference of lung vital
capacity pre and post intervention. The means of lung vital capacity pre and
post was increased by 3.6 ± 0.5 liters to 3.9 ± 0.6 liters, test paired t-test
indicates a mean value of 3.7 ± 0.3 liters (p = 0.000, p <0.05), by the
confidence intervals of 95%. This value indicates that there is positive effect
of swimming activity to changes in lung vital capacity of males medical
students of Jenderal Soedirman University.
