Methods: Forty-one children with mild or moderate asthma were divided into moderate intensity continuous training group (MCT, n=14), high-intensity interval training group (HIT, n=15) and control group (C, n=12). HIT group performed four sessions of HIT (4 × 30-s cycling bouts eliciting 90% maximal aerobic power (MAP), interspersed with 60 s rest) over 8 weeks, 3 times/week; MCT group performed 40 min cycling at 50 %MAP over 8 weeks, 4 times/week; C group maintained their original life habits. Before and after experiment, the level of asthma control was tested by Asthma Control Questionnaire (ACQ-6), and subjects’ participation in physical activity and adverse reaction during exercise were recorded. Results: 1) Compared with baseline, pulmonary function, peripheral blood leucocyte and its classification and counting, inflammatory factors, growth factors and FeNO didn’t change (P > 0.05) in all groups after experiment; in MCT and HIT groups, ACQ-6 scores reduced (P < 0.05), distance of 6MWT increased (P < 0.05), RPE, SBP, DBP and HR after 6MWT decreased (P < 0.05); all parameters in C group had no significant change (P > 0.05). Compared with C group after test, ACQ-6 scores reduced (P < 0.05), distance of 6MWT increased (P < 0.05), RPE, SBP, DBP and HR after 6MWT decreased (P < 0.05) in MCT and HIT groups, and there are no significant differences between MCT and HIT groups (P < 0.05). 2) Exercise duration and
