ABSTRACT
Objective:To observe the effects of 8-week interval anaerobic training on the respiratory function, airway inflammatoion and exercise performance in the asthmatic children,and to provide theoretic and practical evidence for special exercise prescription for the asthmatic children.Methods:Forty-six mild asthmatic children were willingly divided into exercise group (n=23)and control group (n=23).The children in exercise group conducted 8 weeks interval anaerobic training while the children in control group maintained intrinsical lifestyle.Before and after experiment,the respiratory function,airway inflammatory reaction and exercise performance were determined by pneumonometer,nitric oxide determinator and cycle ergometer.Results:One patient of each group was lost to follow up.509 persons in exercise group finished the training;11 persons had adverse reaction and the incidence was 2.2%.After experiment,compared with before experiment,the peak expiratory flow (PEF)in exercise group after experiment was increased (P 0.05).Compared with control group after experiment,all indexes above (PEF,FeNO,MP and PP)in exercise group existed statistical differences (P <0.05).Conclusion:Interval anaerobic training has safetiveness and effectiveness under proper supervision and could improve the respiratory function,reduce the airway inflammation and enhance the exercise performance in the mild asthmatic children.
