An interventional study of Educational intervention and Aerobic exercise in Cystic Fibrosis, sponsored by Universidade Federal do Rio Grande do Norte. Status unknown at 1 site in Brazil. Open to participants aged 6 Years to 18 Years. Per ClinicalTrials.gov, last updated 2019-10-04.

The purpose of this study is to investigate the effects of aerobic exercise on glucose tolerance in individuals with cystic fibrosis.
The hypothesis is that performing High Intensity Interval Training glucose tolerance will improve in individuals with cystic fibrosis.
This is a controlled, randomized, and single blind trial. The first researcher (P1) will be responsible for the randomization process; the second researcher (P2) will be responsible for the evaluations and reevaluations. This evaluator (P2) will be "blind", meaning that for him it is totally unknown in which group each patient will be insert; and the third researcher (P3), will be responsible for statistical analysis.
Individuals will be recruited at the Child and Adolescent Health Care Unit of the Onofre Lopes University Hospital (HUOL) and in the Department of Physical Therapy of the State University of Paraíba (UEPB), Campina Grande - PB, Brazil. They will be evaluated at the Physical Therapy Department of the Federal University of Rio Grande do Norte (UFRN), Natal - RN, Brazil and in the Department of Physical Therapy of the State University of Paraíba (UEPB), in the city of Campina Grande - PB. A pilot study will be carried out and the sample calculation will be done with the data collected to reach a statistical power of 80% and a level of significance of 0.05%. Allocation in the groups will be performed by P1, randomly in blocks by the volunteer being prepubertal or pubertal. The R Core Team software (2015) will be used for this process.
In this study two groups will be considered: control group (CG) and aerobic exercise group (AEG). The CG will be submitted to educational intervention. The AEG will be submitted to the same educational intervention and to the High Intensity Interval Training.
After the pilot study, the patients will be evaluated to obtain information on severity and exacerbation of the disease, quality of life, metabolic evaluation, anthropometric measures, and lung function. All evaluations will be carried out at the same day period (morning). Researcher two (P2) will be responsible for the evaluation and reassessment procedure of the individuals, hence he will be "blind" meaning that for him it is totally unknown in which group each patient will be or was inserted. Individuals will be instructed to do not perform physical activity in the day before the evaluations. After this step, individuals will be randomly distributed in CG or EAG.
Volunteers from both groups will be instructed to maintain nutritional, drug and secretion care. In addition, they will be instructed to do not get engaged in any other kind of physical activity. The intervention will last 2 months and will occur 3 times a week until a total of 24 sessions. After the intervention ends and after the 8-week follow-up, all volunteers will be reevaluated.

Exclusion Criteria:
The subjects will participate of an educational intervention and a High Intensity Interval Training.
Other: Educational intervention · Other: Aerobic exercise
The subjects will participate of an educational intervention.
Other: Educational intervention
It will be an interactive lecture, 60 minutes long. The class will cover physiopathology, complications, treatment and prevention of exacerbations. Audiovisual resources and practical demonstrations of usual care will be used. Individual questions will be answered during the class.
The aerobic exercise program will be performed at home, on a cycle ergometer for lower limbs between 24 and 35 minutes: 5 minutes of warm-up, 14 to 25 minutes of high-intensity interval exercise and 5 minutes of cool down.
Change in glucose tolerance
Glucose tolerance will be determined by measuring fasting Insulin, fasting glucose, OGTT for all patients.
Time frame: Measured at baseline, after 8 and 16 weeks.
Cystic fibrosis Quality of life
the Quality of Life Questionnaire in Cystic Fibrosis (QFC) was translated and validated into Portuguese in 2006. There are four versions of the questionnaire, according to age group: 6 to 11 years (35 questions), 12 and 13 years (35 questions), 14 years or more (50 questions) and parents of children between 6 and 11 years old (44 questions). For children between 6 and 11 years old the application of the questionnaire will be assisted by special cards that will designate the child's response. The questionnaire addresses the physical, body image, digestive, respiratory, emotional, social, nutrition, treatment, vitality, health, social role and weight domains. The scores of each domain range from zero to 100, considering a good quality of life if score above 50.
Time frame: Measured at baseline, after 8 and 16 weeks.
Lung Function
Forced expired volume in one second (FEV1) and forced vital capacity (FVC), FEV1/FVC ratio, forced expiratory flow at 25-75% of the pulmonary volume (FEF25-75).
Time frame: Measured at baseline, after 8 and 16 weeks.
Functional capacity
The 3 minute step test
Time frame: Measured at baseline, after 8 and 16 weeks.
Respiratory muscle strength
Maximum respiratory pressure
Time frame: Measured at baseline, after 8 and 16 weeks.
Exacerbations
Exacerbations of Cystic Fibrosis through the criteria of Fuchs
Time frame: Measured at baseline, after 8 and 16 weeks.
