Health Benefits of an Innovative Exercise Program for Mitochondrial Disorders

Purpose: We determined the effects of an innovative 8-wk exercise intervention (aerobic, resistance, and inspiratory muscle training) for patients with mitochondrial disease.
Methods: Several end points were assessed in 12 patients (19-59 yr, 4 women) at pretraining, posttraining, and after 4-wk detraining: aerobic power, muscle strength/power and maximal inspiratory pressure (main end points), ability to perform activities of daily living, body composition, quality of life, and blood myokines (secondary end points).
Results: The program was safe, with patients" adherence being 94% ± 5%. A significant time effect was found for virtually all main end points (P ≤ 0.004), indicating a training improvement. Similar findings (P ≤ 0.003) were found for activities of daily living tests, total/trunk/leg lean mass, total fat mass, femoral fracture risk, and general health perception. No differences were found for blood myokines, except for an acute exertional increase in interleukin 8 at posttraining/detraining (P = 0.002) and in fatty acid binding protein 3 at detraining (P = 0.002).
Conclusions: An intervention including novel exercises for mitochondrial disease patients (e.g., inspiratory muscle training) produced benefits in numerous indicators of physical capacity and induced a previously unreported shift toward a healthier body composition phenotype.
