Modest sleep restriction does not influence steps, physical activity intensity or glucose tolerance in obese adults.

J Sleep Res 2021 May 5:e13381. Epub 2021 May 5.

Department of Nutrition and Exercise Physiology, University of Missouri, Columbia, MO, USA.

Sleep restriction (SR) (<6 h) and physical activity (PA) are risk factors for obesity, but little work has examined the inter-related influences of both risk factors. In a free-living environment, 13 overweight/obese adults were sleep restricted for five nights to 6 h time-in-bed each night, with and without regular exercise (45 min/65% VO max; counterbalanced design). Two days of recovery sleep followed SR. Read More

A Narrative Review of the Role of Diet and Lifestyle Factors in the Development and Prevention of Endometrial Cancer.

Cancers (Basel) 2021 Apr 29;13(9). Epub 2021 Apr 29.

Gynaecology Oncology Cancer Centre, Liverpool Women's NHS Foundation Trust, Liverpool Women's Hospital, Liverpool L8 7SS, UK.

Endometrial cancer is the most common cancer affecting the reproductive organs of women living in higher-income countries. Apart from hormonal influences and genetic predisposition, obesity and metabolic syndrome are increasingly recognised as major factors in endometrial cancer risk, due to changes in lifestyle and diet, whereby high glycaemic index and lipid deposition are prevalent. This is especially true in countries where micronutrients, such as vitamins and minerals are exchanged for high calorific diets and a sedentary lifestyle. Read More

A Physically Active Status Affects the Circulating Profile of Cancer-Associated miRNAs.

Diagnostics (Basel) 2021 Apr 30;11(5). Epub 2021 Apr 30.

IRCCS Istituto Ortopedico Galeazzi, Laboratory of Experimental Biochemistry & Molecular Biology, 20161 Milano, Italy.

Circulating miRNAs are ideal diagnostics and prognostics biomarkers in cancer since altered levels of specific miRNAs have been associated to development/progression of several cancers. Physical activity is a recognized preventive strategy against several cancers, but it may also modify the baseline levels of cancer-associated miRNAs and, hence, may act as a confounding pre-analytical variable. This study aimed at understanding whether physical activity-dependent changes in cancer-associated circulating miRNAs profile could act as a confounding variable. Read More

Exercise training rescues the electrical activity of liver-projecting DMNV neurones in response to oxytocin in spontaneously hypertensive rats.

J Neuroendocrinol 2021 May 4:e12977. Epub 2021 May 4.

Department of Physiology and Biophysics, Institute of Biomedical Sciences, University of Sao Paulo, Sao Paulo, Brazil.

A neural circuit between the paraventricular nucleus of the hypothalamus (PVN) and the dorsal motor nucleus of the vagus (DMNV) constitutes part of an important parasympathetic autonomic pathway that controls hepatic glucose production. Intracerebroventricular injection of insulin activates oxytocinergic neurones in the PVN and elicits the release of oxytocin into the circulation, which plays an important role in the metabolism of glucose. Moreover, the central action of insulin can reduce the concentration of glucose in blood taken from the hepatic vein of Wistar rats via activation of vagal efferent nerves to the liver. Read More

Does exercise during pregnancy impact organs or structures of the maternal-fetal interface?

Tissue Cell 2021 Apr 16;72:101543. Epub 2021 Apr 16.

School of Human Kinetics, Faculty of Health Sciences, University of Ottawa, Ottawa, Canada. Electronic address:

Exercise during pregnancy has been shown to be associated with improved health outcomes both during and after pregnancy for mother and fetus across the lifespan.

Effects of moderate intensity endurance training and high-intensity interval training on the reproductive parameters of wistar rats overfed in infancy.

Chin J Physiol 2021 Mar-Apr;64(2):106-114

Department of Medicine, Postgraduate Health Program, Federal University of Juiz de Fora, Juiz de Fora, MG, Brazil.

Studies indicate that rapid weight gain at critical development stages, such as the lactation period, is associated with the development of obesity, cardiovascular diseases, and diabetes in the long term. In addition to metabolic changes during adulthood, overweight/obesity may influence reproductive function. Human and animal studies suggest that lifestyle changes through exercise and/or controlled diet result in improved semen quality in obese individuals. Read More

Aerobic Exercise Restores Aging-Associated Reductions in Arterial Adropin Levels and Improves Adropin-Induced Nitric Oxide-Dependent Vasorelaxation.

J Am Heart Assoc 2021 May 3:e020641. Epub 2021 May 3.

Faculty of Sport and Health Science Ritsumeikan University Shiga Japan.

Background Adropin is a peptide hormone that promotes nitric oxide (NO) production via activation of endothelial NO synthase (eNOS) in endothelial cells. Its circulating levels are reduced with aging and increased with aerobic exercise training (AT). Using a mouse model, we hypothesized that AT restores aging-associated reductions in arterial and circulating adropin and improves adropin-induced NO-dependent vasorelaxation. Read More
