Exercise-induced adaptations in patients with Alzheimer ’s disease: the role of circadian scheduling
ConclusionsMost of the authors included in this review indicate morning as the best time of the day to administer physical exercise to patients with AD. Furthermore, some authors considered show benefits to these patients from post-meridian exercise intervention as well as others hypothesize efficacy from exercise circadian programs. Nevertheless, the paucity of studies in this field limits the conclusion of this review. For these reasons, we think that research should invest more to better focus on the circadian approach to physical exercise scheduling for patients with AD. (Source: Sport Sciences for Health)

ConclusionsOur data suggest that there are significant differences analyzing the cortical excitability in athletes, compared to non-athletes. Furthermore, this data confirmed that the exercise training influences the parasympathetic tone, reducing HR. Moreover, a significant reduction in GSR parameters was reported in the athletes group, which is an indicator of stress level. The HR training helps to restore the autonomic balance and improves autonomic control that supports emotional regulation and performance coordination, so the training represents an advantage in reducing anxiety in athletes.

Role of exercise in the mechanisms ameliorating hepatic steatosis in non-alcoholic fatty liver disease
AbstractHepatic steatosis is an abnormal lipid accumulation within hepatocytes, generally present in non-alcoholic fatty liver disease (NAFLD) patients, a starting-point pathology currently associated with other clinical manifestations such as metabolic syndrome, non-alcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and eventually hepatocellular carcinoma. Hepatic steatosis in NAFLD may be induced by mechanisms such as insulin resistance, increased fatty acid uptake, a higher de novo lipogenesis from glucose or acetate, lower fatty acids oxidation and a decrease in fatty acid mobilization from liver. Among different t...
