Dementia is a growing global health challenge that takes a significant toll on both individuals and society. With no cure yet available, finding ways to slow its progression or reduce the risk of developing it is critical for supporting healthy aging. Now, new research points to weight training as a potential way to help protect the brain from dementia.
Regular physical activity is a well-established lifestyle factor that can help reduce the risk of dementia. Interestingly, the benefits of weight training have also been seen in individuals already experiencing mild cognitive impairment. Researchers focused on resistance training because it primarily aims to boost muscle strength, a key priority for aging adults.
In this study, researchers enrolled 44 adults aged 55 and older, all diagnosed with mild cognitive decline. Participants were split into two groups: one group took part in a resistance training program, performing moderate- to high-intensity weightlifting sessions twice a week. The workouts used progressive loading, gradually increasing weight or repetitions as participants gained strength. The control group, in contrast, did not engage in any exercise throughout the study.
After six months, those in the strength training group showed signs of preserved brain volume in key regions tied to Alzheimer’s disease, including the hippocampus and precuneus. They also exhibited positive changes in measures linked to neuron function and brain health.
This study is the first to reveal how weight training influences the structure and health of brain white matter in individuals with mild cognitive decline. Encouragingly, the findings suggest that resistance exercise can be a powerful tool in the fight against dementia, even among those already at elevated risk. As a non-drug intervention, weight training not only helps lower the risk of dementia but also supports improvements in early cognitive decline.
