  • Two approaches, including decreasing exposure time or respiratory rate, can reduce the inhalation of PM2.5 for cyclists during periods of air pollution. These two approaches have contrasting requirement for cycling speed, and the intake of PM2.5 and other pollutant varies from person to person. Therefore, it is an urgent need to develop a PM2.5 inhalation-cycling speed model considering individual differences to determine the optimal healthy cy-cling speed for a minimal PM2.5 inhalation for each cyclist. The energy consumption model calculates air inhalation based on heart rate and individual characteristics, which can be used to obtain the PM2.5 inhalation within single trip in combination with PM2.5 exposure concentration and cycling time. Then, the PM2.5 inhalation-cycling speed model is established based on the correlation between individual cyclists' speed and heart rate characteristics, which can be used to acquire the healthy cycling speed with the derivative methods. The results from 173 subjects in Xi'an indicate that the reduction in PM2.5 inhalation for males and females at their healthy cycling speed is 17.06%, 8.57%, 1.85%, and 2.50% compared to the minimum and maximum cycling speeds, respectively. The relationship between PM2.5 inhalation and cycling speed represents a "U" type curve, with the minimum point corresponding to the healthy cycling speed for minimal PM2.5 inhalation. The healthy cycling speed for males is positively correlated with age, weight, and basal heart rate, while females'healthy cycling speed correlates positively with age and basal heart rate but negatively with weight. The distribution of healthy cycling speeds can provide a reference for individual differences among cyclists, and establish traffic control methods to reduce PM2.5 inhalation of cyclists during polluted weather, and to improve their health during cyclist activities.
