Fasting glycaemia (mg·dL−1) expressed as mean ± standard deviation. CON: control group, received 10 μL saline daily, maintained sedentary. MIT: moderate intensity training group, received 10 μL saline daily. HIT: high intensity training group, received 10 μL saline daily. PM2.5: exposure group, received 5 μg of PM2.5 daily, maintained sedentary. MIT + PM2.5: moderate intensity training group, received 5 μg of PM2.5 daily. HIT + PM2.5: high intensity training group, received 5 μg of PM2.5 daily (n = 5-6 per group). Data analysed by two-way ANOVA followed by Tukey's multiple comparison test. There was an effect of time (P < 0.0001) and no effect of treatment (P = 0.422) or interaction between time and treatment (P = 0.791). The time effects are indicated as ∗P < 0.05, †P < 0.01, and §P < 0.001 versus initial body weight (“before” data) in each respective group.
