Health Benefit Assessment of Running in Urban Areas against the Background of Particulate Matter 2.5 Concentration: The Munich Olympic Park

Abstract

Air pollution while exercising is a health threat to urban residents. The study’s purpose is to conduct a health benefit assessment for running against the background of the Particulate Matter (PM) 2.5 concentration, taking the Munich Olympic Park as a case. The health benefit assessment was done under the assumption that people exercise at different PM2.5 concentrations and with varying duration and intensity. PM2.5 concentrations in and around the Olympic Park area were measured on 25 rain-free days from July until November 2019, using DC1700 (Dylos). The results show that, for the example of a 60-min run at a moderate intensity (60% VO2max), the PM2.5 concentration at which running no longer leads to additional health benefits amounts to 55 μg/m3 (tipping point). Harms outweigh health benefits at 95 μg/m3 (break-even point). The average PM2.5 concentration during the runs to and inside the Olympic Park was above the tipping point on one day, but did not reach the break-even point on any of the days. The average concentration across all days did not reach the tipping or break-even points for any running duration. The Munich Olympic Park provides a potentially health-enhancing space to residents from the perspective of PM2.5-related air pollution.
