Energetic metabolism during effort is impaired in patients with left ventricular dysfunction (Dysf), but data have been lacking up to now on the relative anaerobic vs. aerobic contribution to total energy release during supramaximal effort. Recently, the maximal accumulated oxygen deficit (MAOD) has been shown to be measurable in Dysf ...

Dehydroepiandrosterone Sulfate (DHEAS) is thought to offset hypercortisolemia, which is found in individuals with bipolar disorder. While the cause of bipolar disorder remains unknown, previous studies have linked elevated cortisol levels with various mental health illnesses, including bipolar disorder. Previous studies suggest that exercise increases DHEAS levels in healthy subjects, ...
