Aerobic exercise training to improve lung function in children and adolescents with intellectual disability

Exercise training: Exercise training sessions of 30 minutes' duration, 5 times per week, for 8 weeks. The exercise modalities were walking and running on flat ground and cycling on a cycle ergometer. Participants conducted 10 minutes of each modality at each training session with no break between modalities. The exercise sessions were supervised by a sports coach. The target intensity was moderate, determined by the sports coach who asked the participants about their level of exertion and also noted that their respiratory rates were elevated but that they could still speak in sentences. Other usual daily activities were also maintained throughout the duration of the study. These did not include any other specific exercises, and included daily self care, and group activities such as printing, painting, hand craft, and theatre.
