Impact of aerobic exercise training on age-related changes in insulin sensitivity and muscle oxidative capacity.
Insulin resistance increases and muscle oxidative capacity decreases during aging, but lifestyle changes-especially physical activity-may reverse these trends. Here we report the effect of a 16-week aerobic exercise program (n = 65) or control activity (n = 37) performed by men and women aged 21-87 years on insulin sensitivity and muscle mitochondria. Insulin sensitivity, measured by intravenou...
متن کاملMagnesium supplementation enhances insulin sensitivity and decreases insulin resistance in diabetic rats
Objective(s): Diabetes mellitus has been suggested to be the most common metabolic disorder associated with magnesium deficiency. This study aimed to investigate the effects and mechanisms of magnesium supplementation on insulin receptor activity in elderly type 2 diabetes using a rat model and to provide experimental evidence for insulin resistance improvement by magn...
متن کاملacute aerobic exercise and plasma levels of orexin a, insulin, glucose, and insulin resistance in males with type 2 diabetes
conclusions it seems that in people with type 2 diabetes, acute aerobic exercise can decrease the plasma levels of glucose, possibly through increasing orexin a. in addition, negative energy balance is necessary to decrease the levels of insulin and insulin resistance during acute aerobic exercise. results the analysis of findings in p ≤ 0.05 indicated that acute aerobic exercise caused a signi...
متن کاملCaloric restriction reverses hepatic insulin resistance and steatosis in rats with low aerobic capacity.
Rats selectively bred for low aerobic running capacity exhibit the metabolic syndrome, including hyperinsulinemia, insulin resistance, visceral obesity, and dyslipidemia. They also exhibit features of nonalcoholic steatohepatitis, including chicken-wire fibrosis, inflammation, and oxidative stress. Hyperinsulinemia in these rats is associated with impaired hepatic insulin clearance. The current...
متن کاملEffects of ovariectomy and intrinsic aerobic capacity on tissue-specific insulin sensitivity.
High-capacity running (HCR) rats are protected against the early (i.e., ∼ 11 wk postsurgery) development of ovariectomy (OVX)-induced insulin resistance (IR) compared with low-capacity running (LCR) rats. The purpose of this study was to utilize the hyperinsulinemic euglycemic clamp to determine whether 1) HCR rats remain protected from OVX-induced IR when the time following OVX is extended to ...
