Organisation intracellulaire de la production de l’énergie

mitochondriale et son transfert

Glycolytic muscle

Oxidative muscle

low content in

mitochondria, energy

supplied from glycolysis

signal respiration :

cytosolic ADP, non

effective transfers of

energy, rapidly fatigued

high content in

mitochondria, energy

supplied from oxidative

phosphorylation, signal

respiration : Cr, coupled

transfers (CK shuttle),

resistant to fatigue

“Pulmonary rehabilitation is a comprehensive intervention based on

a thorough patient assessment followed by patient tailored therapies

that include, but are not limited to, exercise training, education, and

behavior change, designed to improve the physical and

psychological condition of people with chronic respiratory disease

and to promote the long-term adherence to health-enhancing

behaviors” 12
