Resistance training could potentially delay or prevent symptoms of Alzheimer’s disease, according to new research. A study conducted on mice with a genetic mutation associated with Alzheimer’s found that hormone levels linked to the disease were lower in mice that underwent a four-week period of resistance training. The mice climbed a steep-incline ladder with weighted loads attached to their tails during the training. Blood samples showed that hormone levels in the resistance-trained mice were normal, similar to those without the genetic mutation. Additionally, analysis of the mice’s brain tissue revealed a decrease in the formation of toxic proteins associated with Alzheimer’s. The researchers also noticed a reduction in restlessness and agitation in the resistance-trained mice, which are early symptoms of the disease. The anti-inflammatory action of resistance exercise may be responsible for its effectiveness in preventing or delaying the onset of Alzheimer’s symptoms. Resistance training, which increases muscle mass and improves insulin sensitivity, can also improve sleep, enhance muscle-related signals to the brain, reduce inflammation, and improve cardiac fitness. The study’s findings support the idea that strength training can reduce cognitive decline, although it is important to consult a physician before starting a resistance training regimen to ensure suitability for individual needs. While the study was conducted on mice, it is consistent with findings in humans and offers hope for a potential therapeutic approach to Alzheimer’s disease.
