Obesity and prediabetes are the two strongest risk factors of type 2 diabetes. It has been reported that TOTUM-63, a polyphenol-rich plant extract, has beneficial effects on body weight (BW) and insulin resistance in mice fed a high fat diet (HFD). The study aim was to determine whether high-intensity interval training (HIIT) and/or TOTUM-63 supplementation improved body composition and glycemic control and gut microbiota composition in a Western diet-induced obesity rat model. Wistar rats received a standard diet (CTRL; control; n = 12) or HFD (HFD; n = 48) for 16 weeks. Then, HFD rats were divided in four groups: HFD, HFD + TOTUM-63 (T63), HFD + HIIT (HIIT), and HFD + HIIT +T63 (HIIT + T63). Training was performed 4 days/week for 12 weeks. TOTUM-63 was included in diet composition (2%). The HIIT + T63 combination significantly limited BW gain, without any energy intake modulation, and improved glycemic control. BW variation was correlated with increased α-diversity of the colon mucosa microbiota in the HIIT + T63 group. Moreover, the relative abundance of Anaeroplasma, Christensenellaceae and Oscillospira was higher in the HIIT + T63 group. Altogether, these results suggest that the HIIT and TOTUM-63 combination could be proposed for the management of obesity and prediabetes.

This study demonstrates the effect of a single high-intensity interval training (HIIT) session on the redox status of rat ovaries with excess adiposity. Forty Wistar female rats (mean (±s.e.m.) weight 94.40 ± 13.40 g) were divided into two groups and fed either a standard diet (SD) or a high-fat diet (HFD) for 62 days. At the end of this period, the rats were subjected to a single HIIT session and were killed 24 h after exercise. Both groups subjected to exercise (SDex and HFDex) generated a significantly higher antioxidant environment by presenting a higher thiol content, which represents a lower oxidation rate of GSH than their respective controls (SD and HFD). The percentage of morphologically normal primary follicles decreased, whereas that of antral follicles increased, in the SDex group. In addition, the HFD group had a higher percentage of degenerated antral follicles than the SD and SDex groups. Cells immunoreactive for α-smooth muscle actin were seen in the cortical stroma and thecal layer enclosing late secondary and tertiary follicles in all groups. Moreover, heme oxygenase and cytochrome P450 family 19 subfamily A member 1 (Cyp19A1) labelling was seen in all antral follicles. Progesterone concentrations were significantly higher in the HFDex than SDex group. In conclusion, this study indicates that a single session of HIIT may result in an improvement in ovary redox status because of metabolic muscle activity by inducing physiological adaptation after exercise in a paracrine manner.

Lipogenic and lipolytic pathways are tightly regulated by nuclear receptors and binding proteins, such as farnesoid x receptor (FXR) and sterol regulatory element binding protein 1c (SREBP-1c). We designed this research to study the effects of high-intensity interval training (HIIT) and high-fat diet (HFD) on hepatic and adipose FXR and SREBP-1c gene expression beside the plasma levels of lipid profile and insulin. 24 male Wistar rats were randomly divided into normal (~12% fat) and HFD (~56% fat) groups with or without participating in the 8 weeks HIIT protocol. Results from two-way ANOVA and Pearson tests (P<0.05) showed that the HFD rats experienced a larger weight gain correlated with dyslipidemia and hyperinsulinemia, higher hepatic and adipose SREBP-1c expression and lower hepatic FXR expression compared with normal diet fed rats. Although HIIT rats showed higher hepatic FXR and lower hepatic and adipose SREBP-1c expression and lower weight gain compared with untrained rats, plasma lipid profile levels had not any significant difference between trained and untrained rats. Interestingly, hepatic FXR expression was negatively correlated with weight gain and SREBP-1c expression in both tissues while only the hepatic SREBP-1c was positively correlated to insulin levels. In conclusion, HFD-induced dyslipidemia could occur via the activation of the hepatic SREBP-1c pathway under the insulin effect. Although HIIT rats showed lower SREBP-1c correlated to hepatic FXR activation it seems diet is more effective on lipid profile than HIIT. Also, in presence of HFD, HIIT only affects adipose lipolysis.

Background and aims: A high-fat diet increases triglyceride (TG) accumulations in hepatocytes and results in non-alcoholic fatty liver diseases (NAFLDs). In this regard, this study investigated the effect of high-intensity interval training (HIIT), along with a high-fat diet on the serum levels of aminotransferases in male Wistar rats. Methods: Forty male Wistar rats were randomly assigned to the standard diet, high-fat diet, exercise + standard diet, and exercise + high-fat diet groups (each containing 10 animals). HIIT program consisted of 6-12 repetitions of 2-minute highs-intensity exercise (85-90% of the maximum speed) interspersed with 1-minute low-intensity exercise (45-50% peak speed) with the frequency of 5 sessions a week over 12 weeks. High-fat diet groups received a diet regimen including 58% fat, 25% protein, and 17% carbohydrate, ad libitum. The blood samples were taken from the left ventricle 48 hours following the last intervention to assess TG, alanine aminotransferase (ALT), and aspartate amino-transferase (AST) concentrations. Data were analyzed using one-way ANOVA and Tukey’s post-hoc tests. Results: The findings showed the mean of ALT, AST, and TG in the high-fat diet group was significantly greater compared to the standard diet group (P=0.001). Furthermore, the mean of ALT, AST, and TG in the exercise + high-fat diet group was significantly lower in comparison with the high-fat diet group (P=0.01, P=0.017, and P=0.012, respectively). Conclusion: Although HIIT ameliorated high-fat diet-induced elevations in the serum levels of TG, ALT, and AST, they did not reach the baseline levels. Thus, it may indicate that a diet as the underlying cause of NAFLDs is more important than any other interventions such as exercise.

High-intensity interval training (HIIT) and linseed oil (LO) supplementation are effective strategies to reduce obesity-induced oxidative stress. Our aim was to determine whether the HIIT + LO combination prevents obesity-induced oxidative stress in high fat diet (HFD)-fed rats. HFD-fed 8-week-old, male, Wistar rats were subdivided in four groups: HFD, LO (2% of sunflower oil replaced with 2% of LO in the HFD), HIIT (4 days/week for 12 weeks), and HIIT + LO. Wistar rats fed a low-fat diet (LFD) were used as controls. Epididymal and subcutaneous adipose tissue, gastrocnemius muscle, liver, and plasma samples were collected to measure oxidative stress markers (AOPP, oxLDL), antioxidant (SOD, CAT, and GPx activities) and pro-oxidant (NOx and XO) enzyme activities. Compared with the LFD, the HFD altered the pro/antioxidant status in different tissues (increase of AOPP, oxLDL, SOD and catalase activities in plasma, and SOD activity increase in liver and decrease in adipose tissues) but not in gastrocnemius. LO upregulated CAT activity and decreased NOx in liver. HIIT alleviated HFD negative effects in liver by reducing SOD and NOx activities. Moreover, the HIIT + LO combination potentiated SOD activity upregulation in subcutaneous tissue. HIIT and LO supplementation have independent beneficial effects on the pro/antioxidant balance. Their association promotes SOD activity in subcutaneous adipose tissue.

Background: Obesity is a multi-factorial physical disorder that results in high serum lipid levels and glycemic disorders. On the other hand, regular exercise and administration of Eryngium Campestre (EC) have glucose and lipid-lowering effects. Objectives: The present study aimed to review the effect of high-intensity interval training (HIIT) with EC on lipid profile and glycemic indices in high-fat diet (HFD)-induced obese rats. Methods: Twenty-four obese rats were divided into four groups, including: (1) control, (2) HIIT, (3) EC, and (4) HIIT+EC. To investigate the effect of obesity on research variables, six rats were assigned to a healthy control group. During six weeks, groups 2 and 4 received HIIT three days per week, and groups 3 and 4 received 30 mg/kg EC by gavage. Data were analyzed using the Shapiro-Wilk test and one-way ANOVA with Tukey’s post hoc test (P ≤ 0.05). Results: Obesity significantly increased cholesterol (Cho), triglyceride (TG), insulin, and glucose levels (P ≤ 0.05). However, HIIT significantly decreased Cho, TG, insulin, and glucose levels (P ≤ 0.05), and EC significantly decreased Cho, TG, low-density lipoprotein (LDL), insulin, and glucose levels (P ≤ 0.05). Besides, HIIT+EC significantly decreased LDL and insulin (P ≤ 0.05). HIIT+EC could decrease LDL more than did HIIT (P ≤ 0.05). Conclusions: Although HIIT and EC alone improved the lipid profile and glycemic indices in obese rats, HIIT combined with EC had greater effects on the decrease of LDL compared to HIIT.

BACKGROUND Obesity is known as one of the major causes of epidemiologic diseases worldwide; therefore, the introduction of treatment strategies by medical professionals, such as the use of various medicines and exercise programs to reduce fat or prevent obesity, is on the rise. Recently, researchers have shown special interest in assessing the effect of lipolytic adenosine and vitamin D deficiency, as well as the effect of exercise, on decreasing body fat percentage. OBJECTIVE This study has been designed to examine the effect of adenosine and vitamin D3 injections, in conjunction with high-intensity interval training and isocaloric moderate-intensity training, on the metabolic parameters of obesity induced by a high-fat diet. METHODS This is an experimental study using 92 Wistar rats. At 6 weeks of age, the rats' weights will be recorded, after which they will have 1 week to adapt to their new environment before being divided into 12 groups. The rats will participate in a 2-stage experimental intervention, including a 13-week fattening diet phase followed by a 12-week exercise training phase consisting of an exercise program and the injection of adenosine and vitamin D3. Groups 1 and 2 will have a normal diet, and the other groups will have a diet of 40% fat, with free access to food and water up to the second half of the second stage of the study (end of the sixth week of training). After termination of the interventions, tissue collection and molecular assessments (blood for biochemical, tissues for gene expression analyses, and anthropometrical indexes) will be performed. RESULTS The project was initiated in April 2017 and completed in December 2017. Data analysis is under way, and the first results are expected to be submitted for publication in November 2018. CONCLUSIONS We hypothesize that weight loss–induced molecular changes and upregulation will be observed in line with an increase in lipolysis and beta oxidation in muscle and fat tissue as a result of performing isocaloric training in drug-receiving rats and groups on a high-fat diet.
