Air pollution is among the leading environmental threats to health around the world today, particularly in the context of sports and exercise. With the effects of air pollution, pollution episodes (eg, wildfire conflagrations) and climate change becoming increasingly apparent to the general population, so have their impacts on sport and exercise. As such, there has been growing interest in the sporting community (ie, athletes, coaches, and sports science and medicine team members) in practical personal-level actions to reduce the exposure to and risk of air pollution. Limited evidence suggests the following strategies may be employed: minimising all exposures by time and distance, monitoring air pollution conditions for locations of interest, limiting outdoor exercise, using acclimation protocols, wearing N95 face masks and using antioxidant supplementation. The overarching purpose of this position statement by the Canadian Academy of Sport and Exercise Medicine and the Canadian Society for Exercise Physiology is to detail the current state of evidence and provide recommendations on implementing these personal strategies in preventing and mitigating the adverse health and performance effects of air pollution exposure during exercise while recognising the limited evidence base.

“…Current studies have shown that aerobic and resistance exercises decrease all-cause mortality through improving cognitive functions, mental health, body composition and reducing cardiovascular risk [ 23 , 24 ]. However, numerous epidemiological and toxicological studies have shown the negative association between environmental pollutants exposure during exercise and human health benefits, including cardiovascular disease, respiratory injuries, metabolic disorders and premature death [ 25 , 26 ]. Among them, POPs account for important factors of environmental health risks.…”

“…Current knowledge on the effects of air pollution exposure on total lung capacity and diffusing capacity is limited and mixed. Some animal [ 17 – 20 ] and human [ 21 – 34 ] studies have shown that exposure to air pollution has adverse effects on total lung capacity [ 17 , 23 , 24 , 26 – 28 ] and diffusing capacity [ 19 , 20 , 23 , 24 , 29 – 33 ], but others have shown no effects [ 18 , 21 , 22 , 25 , 34 ]. Most previous studies have focused on acute [ 20 , 25 , 28 – 30 , 32 – 34 ] or short-term [ 21 – 24 ] effects, but only a few have reported long-term effects [ 17 – 19 , 26 , 27 , 31 ].…”

Background Some evidences have shown the association between air pollution exposure and the development of interstitial lung diseases. However, the effect of air pollution on the progression of restrictive ventilatory impairment and diffusion capacity reduction is unknown. This study aimed to evaluate the effects of long-term exposure to ambient air pollution on the change rates of total lung capacity, residual volume, and diffusion capacity among the elderly. Methods From 2016 to 2018, single-breath helium dilution with the diffusion capacity of carbon monoxide was performed once per year on 543 elderly individuals. Monthly concentrations of ambient fine particulate matters (PM2.5) and nitric dioxide (NO2) at the individual residential address were estimated using a hybrid Kriging/Land-use regression model. Linear mixed models were used to evaluate the association between long-term (12 months) exposure to air pollution and lung function with adjustment for potential covariates, including basic characteristics, indoor air pollution (second-hand smoke, cooking fume, and incense burning), physician diagnosed diseases (asthma and chronic airway diseases), dusty job history, and short-term (lag one month) air pollution exposure. Results An interquartile range (5.37 ppb) increase in long-term exposure to NO2 was associated with an additional rate of decline in total lung volume (− 1.8% per year, 95% CI: − 2.8 to − 0.9%), residual volume (− 3.3% per year, 95% CI: − 5.0 to − 1.6%), ratio of residual volume to total lung volume (− 1.6% per year, 95% CI: − 2.6 to − 0.5%), and diffusion capacity (− 1.1% per year, 95% CI: − 2.0 to − 0.2%). There is no effect on the transfer factor (ratio of diffusion capacity to alveolar volume). The effect of NO2 remained robust after adjustment for PM2.5 exposure. Conclusions Long-term exposure to ambient NO2 is associated with an accelerated decline in static lung volume and diffusion capacity in the elderly. NO2 related air pollution may be a risk factor for restrictive lung disorders.
