A new study released by the American College of Sports Medicine says female marathoners may be most harmed by air pollution.
Researchers led by Virginia Tech civil and environmental engineer Lindsey Marr compared annual race times for the top three male and female finishers for seven marathons over 8 to 28 years, then cross-referenced those results with air pollution and temperature on race day. After accounting for warmer temperatures, they found that higher levels of particles in the air were associated with slower times for women, but not for men.
