Effects of oral supplementation of coenzyme Q10 on 31P-NMR detected skeletal muscle energy metabolism in middle-aged post-polio subjects and normal volunteers.
The effects of oral supplementation of 100 mg coenzyme Q10 (CoQ10) for 6 months on muscle energy metabolism during exercise and recovery were evaluated in middle-aged post-polio (n = 3) and healthy subjects (n = 4) by the use of phosphorus-31 nuclear magnetic resonance spectroscopy. The metabolic response to isometric plantar flexion at 60% of maximal voluntary contraction force (MVC) for 1.5 min was determined in gastrocnemius muscles before, after 3- (3MO) and 6-month (6MO) of CoQ10 supplementation. The MVC of plantar flexion was unchanged following CoQ10 supplementation. The resting Pi/PCr ratio in gastrocnemius muscles of all subjects decreased after 3MO- and 6MO-CoQ10 (P
