In addition to pollution from gym equipment, the ventilation system of a gym can inadvertently draw in pollutants from external sources, according to researchers.
Recently, a group of Chinese scientists conducted a study to investigate the air quality in gyms, aiming to clarify the composition and concentration of air pollutants in indoor exercise environments.
Professor Sun Yele from the Institute of Atmospheric Physics at the Chinese Academy of Sciences, who is also the author of the study, stated that over a continuous 20-day period, they meticulously analyzed the air using a high-resolution aerosol mass spectrometer.

Their findings, published in the journal Environmental Science & Technology Letters, revealed that indoor air in gyms contains a higher proportion of organic aerosol (OA) compared to outdoor environments. Specifically, about 50% of the particulate matter inhaled in gyms is OA, significantly up from the approximately 40% observed outdoors.
Moreover, the scientists identified two distinct types of OA present in the gym environment. The first type, siloxane organic aerosol (SiOA), was unexpectedly found at high concentrations, accounting for 7-11% of the total OA.
According to Professor Sun, the presence of SiOA is attributed to silicon polymer lubricants used in exercise equipment. Additionally, OA from cigarette smoke or cooking activities in nearby areas also contributes to the indoor air quality.
The researchers noted that the gym’s ventilation system could inadvertently suck in pollutants from external sources.
Therefore, Professor Sun believes that understanding the composition and concentration of pollutants in exercise environments is crucial for assessing potential health risks associated with exercising, as increased breathing rates during workouts will enhance the likelihood of inhaling these particles, impacting human health.
The study advocates for a comprehensive assessment of air quality across various fitness facilities, considering factors such as equipment diversity, occupancy rates, and ventilation systems. Such investigations are vital tools for developing effective strategies to protect indoor air quality and minimize health risks related to exercise.
Professor Sun also expressed a desire to expand the research by conducting tests in different gyms to determine the prevalence of these pollutant particles.
He is optimistic about future improvements in equipment, envisioning real-time monitoring of OA and volatile organic compounds to enhance understanding of air quality in gyms.
