Summary: The study investigates the role of NOX2 in the interaction between diet-induced insulin resistance and exercise training in skeletal muscle. The results suggest that NOX2 deficiency worsens the effects of a high-fat diet on body weight, body composition, and glucose intolerance. Additionally, the lack of NOX2 activity during exercise training reduces several metabolic adaptations in skeletal muscle.

Summary: Studies have shown that low-volume high-intensity interval training is beneficial for cardiorespiratory fitness in women and yields similar improvements in both men and women. Limited research suggests conflicting results regarding insulin sensitivity and skeletal muscle mitochondrial responses in women.

Summary: Obesity is associated with insulin resistance and T2DM, while physical exercise can improve this condition by increasing the expression of spexin in adipose tissue. Combining spexin with exercise training is an effective therapeutic strategy for age-associated diseases.

Summary: Exercise with weight loss improves insulin sensitivity, aerobic capacity, and body composition in older obese adults. It also reduces ectopic fat and preserves lean mass and strength. However, weight loss alone may lead to decreased lean mass and strength. Therefore, regular exercise is important for older adults aiming to lose weight in order to achieve cardiometabolic and functional benefits that may not occur with calorie restriction-induced weight loss alone.

Summary: The study aims to evaluate whether changes in extracellular vesicles (EVs) after acute exercise are associated with the responder phenotype following resistance training (RT). The results indicate that youth with obesity who respond to RT produce larger EVs that mainly express 150-300 nm EVs, while non-responders produce smaller EVs sized 50-150 nm.

Summary: Androgens play a complex role in regulating insulin sensitivity, with decreased levels posing a risk for insulin resistance in men and excess levels contributing to insulin resistance in women with PCOS. Hormones like androgens and estrogens can induce mitochondrial oxidative phosphorylation, leading to ATP surplus and subsequently insulin resistance in diabetes. The hormone synergy-based view proposes a unified mechanism for the distinct metabolic roles of androgens in controlling insulin action in men with hypogonadism and women with PCOS.

Summary: Physical exercise can restore the levels of RhoA and ROCK2 proteins in the skeletal muscle of obese animals, increase phosphorylation of IRS1 and Akt proteins, and decrease levels of inhibitory regulators such as PTEN and PTP-1B. These findings suggest that exercise-induced upregulation of the RhoA-ROCK2 signaling pathway in skeletal muscle is associated with improved systemic insulin sensitivity in obese mice.

Summary: This study compared the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on adults with overweight and obesity. The results showed no significant differences in weight, BMI, waist circumference, or body fat mass between the two training methods, but a moderately beneficial effect of HIIT on insulin sensitivity was observed. The study had limitations in terms of heterogeneity in training protocols and measurements, as well as a risk of bias.

Summary: The protein CTRPl3 is found to play a role in regulating insulin secretion and metabolism. It has been shown to improve glucose metabolism and triglyceride clearance, reduce obesity and inflammation when deficient. Genetic variation of CTRP13 expression in humans may be associated with metabolic syndrome.

Summary: This study evaluated the effects of moderated aerobic treadmill exercise training on pancreatic islet cell viability and function in mice consuming a high-fat and sucrose diet. The results showed that exercise training can slow down and prevent adverse metabolic effects associated with consuming a westernized diet.

Summary: This study investigates the association between aldehyde exposure and sex hormone levels. The results show that certain aldehydes are negatively associated with sex hormones, with specific effects observed in different genders and age groups. Further research is needed to confirm the causal relationship and explore the underlying mechanisms.

Summary: Obesity is directly associated with insulin resistance and type 2 diabetes, and the liver plays a crucial role in maintaining healthy blood glucose levels. While aerobic exercise has been shown to improve insulin action in the liver, the effects of strength training in this context are not well understood. This study found that short-term strength training enhances insulin sensitivity in the liver of obese mice, reducing the activity of hepatic FOXO1 and improving glycemic control.

Summary: The study demonstrated that 12-week stair walking training improved body composition parameters in Chinese females with obesity, particularly showing the superiority of the descending stair exercise protocol in improving insulin sensitivity, which may be attributed to the decreases observed in TNF-alpha levels.
