What the trial is, and whether it could suit you

This prospective, multicenter, cross-sectional, repeated-measures comparative study compared functional and biochemical response profiles to exercise between 2 groups of chronically ill patients (chronic renal failure dialysis patients and patients with metabolic syndrome) and a group of healthy subjects. The hypothesis is that the addition of plasma metabolic intermediates associated with energy disorders linked to insulin resistance, will improve the sensitivity of the assessment of muscle oxidative metabolism abnormalities, as reported in exercise intolerant subjects. In this way, the metabolomics approach during exercise would provide a biological and functional "signature" of insulin resistance of muscular origin, discriminating between insulin-resistant patients, healthy control subjects and dialysis patients, with an exercise metabolic profile approaching that observed in insuli
