Summary

The prevalence of chronic respiratory failure (CRF) is increasing worldwide and will become the 3rd cause of death by 2020. At the stage of the disease requiring ventilatory assistance, this relates to 50,000 patients in France, life expectancy is very limited, and quality of life is poor.

CRF led to a reduction in muscle mass, which is found in 35 and 55% of patients, in some to a profound cachexia. A reduced fat free mass (FFM) is a factor associated with a poor tolerance to exercise and an halved survival. The exact causes and mechanisms leading to cachexia are not yet established. Recently, a chronic inflammatory condition has been quoted as a putative cause. This chronic inflammation would involve the molecular mechanisms leading to poor regulation of the balance of synthesis / protein degradation in muscle. A decrease in plasma and muscle amino acids was found among patients with a low FFM.. In addition, a decrease of plasma levels of some anabolic hormones, GH and androgens or IGF-1 has been found that could explain a lack of protein synthesis.

It is now well established that respiratory rehabilitation, including a program of exercise reconditioning, increases tolerance to exercise and improve the quality of life. Besides the classical type of endurance exercises stimulating the cardio-respiratory system, it is suggested to add resistance exercises. Several studies have reported the benefit of this strategy but the link with intracellular molecular pathways has not been described; moreover, it is unknown whether the existence of an initial muscular atrophy influences the gain in muscle strength/mass.
