[Daily physical activity in adult patients with cystic fibrosis]. / Activité physique quotidienne de patients adultes atteints de mucoviscidose.

Assessment of daily physical activity (DPA) is a major element in the development of respiratory rehabilitation. The aim of this study was to evaluate the DPA and the daily energy expenditure (DEE) in adult patients with cystic fibrosis. Thirty adult patients (16 women, 14 men, mean age 27.1±8.4 years) with cystic fibrosis (FVC: 69.2±19%, FEV1: 55.1±24%, BMI: 20.5±3.6kg/m(2)), in stable condition were included in the study. The questionnaire allowed DPA to estimate DEE from the intensity and type of activity. This tool divides the DEE into four intensity levels: less than 1 Metabolic Equivalent Task (MET), greater than 1 and less than 3 METs, 3-5 METs, and greater than 5 METs. A shuttle test for estimating VO(2) peak was performed in all patients. The DEE reached 9478.4±3224.3kJ24h(-1) and was significantly and highly correlated with calculated peak VO(2) (l/min) (r=0.876, P=<0.001); 22% DEE was less than 3 METs, 10% between 3 and 5 METs et 2,5% greater than 5 METs; 65% DEE was less than 1 MET. There was a strong correlation between DEE and BMI (r=0.860, P=<0.001), a low correlation with FVC (r=0.423, P=0.02). This questionnaire is relevant for estimating DPA and DEE in patients with cystic fibrosis and is an interesting test to be used to evaluate changes in patients after pulmonary rehabilitation.

[Physical activity and exercise training for patients with cystic fibrosis]. / Activité physique et réentraînement à l'effort du patient atteint de mucoviscidose.

In France patients with cystic fibrosis benefit from a multidisciplinary follow-up in Cystic Fibrosis Centres. In this follow-up, despite the numerous therapeutic benefits of exercise in this disease, little emphasis is placed on the promotion of physical activity. The aim of this article is to improve this aspect of management, giving advice from a working group of experts, based on the medical literature and clinical experience. These proposals include quantification of physical activity, evaluation of exercise, training and rehabilitation programs and finally, modification of behaviour to include physical activity in the overall cystic fibrosis treatment strategy. It is intended to set up multicentre studies to evaluate the impact of these proposals.
