LKB1 phosphorylates members of the AMP-activated protein kinase (AMPK) family. LKB1 and AMPK in the skeletal muscle are believed to not only regulate fuel oxidation during exercise but also exercise capacity. LKB1 was also required to prevent diaphragm fatigue, which was seen to affect exercise performance. Using mice expressing dominant ...

Non-invasive ventilation (NIV) assists breathing and thus improves oxygenation in patients with Kyphoscoliosis. The benefits of short- and long-term intermittent nocturnal in such patients have been reported previously (improvement of vital capacity, total lung capacity, muscle strength, daytime oxygenation, exercise capacity, and pulmonary hypertension). We review this important study reporting ...

We hypothesized that the changes in blood oxidant/antioxidant status during incremental maximal cycling exercise could affect the motor drive to leg muscles. Indeed, the oxygen free radicals activate the metabosensitive muscle afferents which are suspected to elicit an adaptive motor response delaying fatigue. Fifteen healthy subjects performed an incremental cycling ...
