Study Notes
Air Pollution and Exercise
- Air pollution is one of the leading environmental threats to health around the world today.
- The primary route of exposure for most vapors, gases, and particles is through inhalation.
Particulate Matter (PM)
- PM is often referred to as ultrafine particles, which can have a significant impact on athletic performance.
- The best-understood effect of PM on physiological systems relevant for athletic performance is its impact on the respiratory system.
Diesel Exhaust (DE)
- DE is a major source of ground-level ozone (O3).
- Particle emissions from DE can react with NOx to form ground-level O3.
Nitrogen Oxides (NOx)
- NOx is primarily formed from during natural events such as forest fires or volcanic eruptions.
- When combined with volatile organic compounds (VOCs), NOx reacts to form ground-level O3.
Volatile Organic Compounds (VOCs)
- VOCs are often components of industrial emissions and can react with NOx to form ground-level O3.
- They are also a key contributor to the generation of smog and acid rain.
Sulfur Oxides (SO2)
- SO2 is primarily formed from industrial emissions and can react with water vapor to form sulfuric acid and sulfate.
- It is a key contributor to the generation of smog and acid rain.
Carbon Monoxide (CO)
- CO is a product of incomplete combustion of hydrocarbon-based fuels and presents as a colorless, odorless, tasteless, but poisonous gas.
- Exposures to high concentrations of CO are associated with aggravated respiratory symptoms including coughing, wheezing, and difficulty breathing.
Air Quality Health Index (AQHI)
- The AQHI is a tool used to provide the public with information on the health risks associated with air pollution.
- The primary purpose of the AQHI in Canada is to provide a standardized system for reporting air quality.
Mitigating the Effects of Air Pollution
- One potential benefit of using low-cost wearable air pollution sensors for athletes is to obtain real-time data on air pollution levels.
- The recommended strategy to mitigate the effects of air pollution during exercise is to plan outdoor workouts during times when pollution levels are lowest.
- Moving an exercise bout indoors when ambient pollution is high can lead to increased exposure to indoor pollutants.
Exercise and Air Pollution
- Exercise intensity generally affects the inhaled dose of air pollution, with higher intensities increasing the dose.
- The limited evidence suggests that high-intensity exercise may have a greater impact on health and performance effects of air pollution.
Indoor and Outdoor Air Pollution
- The ratio of indoor-outdoor air pollution concentrations in sporting facilities can vary depending on factors such as ventilation and air exchange rates.
- A key factor to consider when planning the location for outdoor exercise with regard to air pollution levels is the proximity to industrial sources and traffic.
