The combined effects of resistance and endurance training with ursolic acid supplementation on some Alzheimer's disease-related biomarkers in a rat model of type 2 diabetes

Type 2 diabetes is associated with increased inflammation and a risk of Alzheimer's disease (AD). This study aimed to assess the impact of exercise with ursolic acid (UA) on some protein levels in the brains of aged male Wistar rats with diet-induced Type 2. We investigated the effects of exercise with UA on protein levels in rats with type 2 diabetes. The rats were divided into seven groups and underwent different exercise or UA protocols.

The results showed that type 2 diabetes led to increased levels of tau, IL-1β, TNF-α, and c-Jun, and decreased levels of IRS2 protein. Endurance training improved tau, Jun, and IRS2 levels. UA reduced increased levels of tau, IL-1β, TNF-α, and c-Jun, and increased IRS2 levels. Combining the supplement with training led to further improvements.

These findings suggest that combining training and UA partially reversed the inflammation in the Type 2 diabetes model. However, further research is needed to understand how UA consumption with or without training protocols can reduce the risk of AD in type 2 diabetes.
