Air intake parameters by sex and by route. Ventilation averages with pollution concentration at each time point determined estimated values

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]
