Comparison of lung function between breath-holding diving and non-breath-holding diving fishermen in Ambon city

Abstract

Abstract Breath-hold diving is a traditional method used by fishermen to catch fish or other marine organisms. When humans hold their breath during diving, generally their body will develop physiological changes, and with regular exercise, this can improve the lung function. Based on many studies reported, there is an increase in lung function in breath-hold diving fishermen. The objective of this study was to analyze the comparison of pulmonary function between breath-hold diving fishermen and non-divers fishermen in Ambon. This study uses analytical methods with a cross-sectional approach using primary data of 15 breath-hold divers and 15 non-divers fishermen sample with same background of healthy behavior. The pulmonary function differences between breath-hold diving fishermen and non-diving fishermen were analyzed using t-student test. Pulmonary function parameters i.e. VC, FVC, and FEV1% was measured using spirometer. The results of this study showed that mean value of lung function comparison between breath-hold diving fishermen and non-breath lung function fishermen in vital capacity (VC) ratio was 3.48 ± 0.5 vs. 3.01 ± 0.63 (t α(2)0.05:P = 0‘03), forced vital capacity (FVC) was 2.19 ± 0.45 vs. 1.84 ± 0.46 (t α(2)0.05:P = 0.045), and forced expiratory volume in one second (FEV1%) was 91.46 ± 9.12 vs. 83.44 ± 10.3 (t α(2)0.05:P = 0.03). The lung function comparison in breath-hold diving fishermen and non-diver fishermen showed that there is a significant difference in lung function between breath-hold fishermen and non-diver fishermen. The conclusion of the research is, with the same background of life behavior, the lung function of breath-hold diving fishermen is better than non-diver fishermen.
