The findings of the current investigation have shown that hesperidin supplementation in addition to continuous swimming (CSH) or interval swimming (HSE) NU7026 nmr improved biochemical and oxidative biomarkers in rats. Swimming training by itself, CS and IS groups, or in association with hesperidin, CSH and HSH groups, during four weeks improved glucose metabolism, decreased total cholesterol, LDL-C and triglycerides, and increased

HDL-C. Furthermore, there was also an enhancement in the antioxidant capacity in the continuous swimming with hesperidin supplement, CSH group. Supplementation with hesperidin did not affect gain weight of rats during the 4-week period, but swimming training, mTOR inhibitor continuous or interval, was an important factor in reducing the weight gain of all trained groups, suggesting that energy expenditure by exercise was the key factor to Z-VAD-FMK ic50 maintaining body weight [26]. Serum glucose concentration was significantly decreased when the animals were treated with hesperidin, whether associated with swimming or not, CSH, ISH and CH. Recent reviews have shown that regular exercise, continuous or interval, reduced serum glucose

by improving insulin sensitivity [27, 28], and high intense aerobic exercise induces an improvement of glucose control and adaptation in skeletal muscle [29]. According to the author, blood glucose was reduced by 13% over the 24-h period following training, and the postprandial glucose spikes were also reduced for several days afterwards.

A recent study with rats that underwent interval swimming showed higher production of the glucose transporter GLUT-4, which is a determining factor for the transport and glucose uptake [30]. Moreover, hesperidin supplementation has important hypoglycemic effects by modulation of gene expression of hepatic enzymes such as glucokinase and glucose-6-fosfatase which are selleck chemical involved in the final step of catalyzing the gluconeogenesis and glycogenolysis, thus playing a role in regulating the homeostatic plasma glucose [31]. Others [32] have shown that isolated hesperidin in rats increased significantly the number of GLUT-2 and GLUT-4 carriers enhancing cellular signaling glucose and consequently reducing insulin resistance. Increased levels of physical activity stimulate favorable changes on the levels of circulating lipoproteins, lowering the risks of metabolic disorders such as dyslipidemias, metabolic syndrome and diabetes [5–7]. These changes can vary according to the quantity and intensity of the training, which can decrease cholesterol and triglyceride levels and increase HDL-C [33, 34], although a significant increase of HDL-C was more common with high-intensity resistance exercise [35].
