The effect of exercise time in three different time (Morning, afternoon, evening) on lung vital capacity reviewed from meteorology parameters

Abstract

Objectives: Lebak Siliwangi Sports Center or Ganesa Sports Facility (SARAGA) ITB is a miniature of Bandung because it is located in a basin area and it has a tendency to be exposed to air pollution from motor vehicles. Thus it is necessary to do a study of the air pollution effects on health of people who do sports activities at SARAGA ITB. Methods: The research methodology used is a quantitative descriptive method. The sample of this study is thirty (30) visitors of SARAGA who routinely exercise in the morning, afternoon and evening using purposive sampling. The researcher measure their lung vital capacity before and after exercising with the SP10 ContecTM Spirometer. Meteorological parameters were measured at each exercise time using Laser Egg Origins Smart Air Quality Monitor for PM 2.5, while temperature and humidity were measured using the Weather Station W200. Results: The results of this study consecutively are, from meteorology parameter is PM2.5, temperature and humidity in terms of exercise time (in the morning, afternoon and evening)is in the morning PM.2.5 (10), the temperatureis 28°C, the humidity is55%; in the afternoon is PM.2.5 (29) with the temperatureof 25.1°C, and thehumidity is 77%; in the evening is PM.2.5 (94), thetemperature is 21.7°C, and the humidity is 89%. While the lung vital capacity on the three exercise time (morning, afternoon and evening) experience a significant momentary decline with p-value < 0.05, with a morning value as much (3.49:3.22), in the afternoon as much (3.48:3.20), and in the evening as much (3.58:3.39). Conclusions: In conclusion, the peak PM 2.5 air pollution occurs at night, but this does not directly affect the decreased lung vital capacity shortly after doing exercise. However, the factors that need to be considered are temperature/UV index and air humidity because these two factors have a relationship with the decreased lung vital capacity shortly after exercise.
