The Influence of Drinking Coffee to the Lung Function Forced Expiratory Volume in One Second (FEV1) Fourth Grade Male Student Faculty of Medicine Universitas Islam Bandung Period 2016 until 2017
Abstract
Coffee is a very popular drink around the world. Indonesia is the fourth largest producer of coffee in the world. Coffee has a variety of substances, one of which is caffeine. Caffeine has a physiological effect on our body one of them helps overcome asthma in increasing lung capacity. The purpose of this study was to determine the effect of drinking coffee on lung capacity (FEV1) at 30 minutes, 1 hour, and 3 hours after drinking coffee on male students of Faculty of Medicine Universitas Islam Bandung Bandung. This research uses experimental analytic method. The subjects of the study were fourth grade collage students of Faculty of Medicine, University of Islam Bandung as many as 20 men who have fulfilled the inclusion and exclusion criteria given dosage of 3-5mg / kgBB caffeine or 8 grams of arabica coffee and tested using spirometry. The results showed an increase in lung capacity (FEV1) at 30 minutes, 1 hour, and 3 hours, especially at 1 hour after drinking arabica coffee with Friedman Test and Pearson Correlation Test, simple regression test showed p = <0.001 <0.05) with a more significant result at 1 hour after drinking coffee. This is caused by substances contained in coffee that is caffeine that can cause vasodilation of the smooth muscle of the respiratory tract.
