From: Particulate matter exposure and health impacts of urban cyclists: a randomized crossover study
Participant group mean or route mean | Ride time (minutes) [sd] | Mean \( {\dot{\mathrm{V}}}_{\mathrm{E}} \) in L/min at rest [sd] | Mean \( {\dot{\mathrm{V}}}_{\mathrm{E}} \) in L/min during ride by HR [sd] | Estimated intake of PNC during trial (particles) [sd] | Estimated volume of air inhaled at rest during equivalent ride time (Litres) (resting \( {\dot{\mathrm{V}}}_{\mathrm{E}} \) x ride time) [sd] | Estimated volume of air inhaled during ride (Litres) (ride mean \( {\dot{\mathrm{V}}}_{\mathrm{E}} \) x ride time) [sd] | Ratio of \( {\dot{\mathrm{V}}}_{\mathrm{E}} \) riding compared to at rest [sd] |
