Exercise and Brain Health: The Role of Deadlifts and Other Activities

As Alzheimer’s disease and dementia rates increase, many seek ways to protect brain health with age. Neurophysiologist Louisa Nicola, committed to combating Alzheimer’s, discussed exercise’s role in brain health on the The Diary of a CEO podcast. Nicola emphasized the deadlift as a dominant exercise for engaging nearly the whole body.

According to Nicola, the deadlift involves many muscles, such as the erector spinae, glutes, quadriceps, serratus anterior, and calves. This extensive muscle engagement makes the deadlift comparable to a barbell squat. Nicola asserted that lifting heavier weights demands more brain resources, suggesting enhanced brain benefits.

Dementia, especially Alzheimer’s, remains a global concern. Alzheimer’s accounts for 60 to 80 percent of dementia cases, as per the Alzheimer’s Association. Though treatments and preventative measures are under research, physical activity is recognized as crucial for healthy aging and dementia risk reduction.

Nuances and Benefits of Deadlifts for the Brain

Dr. Joanna Fong-Isariyawongse, a neurologist and sleep specialist, stated in Newsweek there are nuances in claiming one exercise is superior or that heavy lifting consistently yields better outcomes. Different exercises support various aspects of brain health. For instance, resistance training aids cognition, aerobic exercises like walking improve memory, and balance exercises such as tai chi benefit older adults.

Dr. Sergio Guiteau remarked that no direct evidence links heavier weightlifting to reduced dementia risk. A combination of resistance training and activities that challenge balance and coordination is more effective than focusing solely on lifting weight in deadlifts.

Dr. Parth Bhavsar highlighted that brain protection involves factors beyond heavy lifting. These include consistency, proper technique, cardiovascular health, sleep, blood pressure control, insulin sensitivity, and injury prevention. While deadlifts are an excellent strength exercise when performed safely, the best brain-beneficial exercise encompasses safety, progress, and consistency.

Alternative Exercises for Brain Health

Experts noted that heavy deadlifts aren’t necessary for brain health benefits. Fong-Isariyawongse suggested machine weights, resistance bands, bodyweight exercises, walking, and tai chi as alternatives that reduce injury risk.

Bhavsar listed alternatives like trap-bar deadlifts, kettlebell deadlifts, Romanian deadlifts, sit-to-stand movements, goblet squats, step-ups, leg presses, farmer carries, resistance-band rows, and sled pushes.

Dr. Mariam Zakhary mentioned deadlifts’ effectiveness due to engaging multiple muscle groups and enhancing coordination, balance, and motor function. However, similar benefits arise from sit-to-stand exercises, chair squats, resistance-band activities, and supervised machine-based strength training. Guiteau recommended squats, step-ups, and resistance-band exercises, especially for individuals with mobility issues or prior injuries.

The Key to Brain Health: Consistency

Experts concurred that consistency in exercise matters more than any single activity. Bhavsar referenced the 2024 Lancet commission on dementia, noting physical inactivity as a modifiable risk factor. The CDC and WHO also advocate for regular physical activity to reduce cognitive decline risks.

Zakhary reinforced that consistency is vital, suggesting exercises challenge both cardiovascular and musculoskeletal systems safely over time. Fong-Isariyawongse noted activities beyond physical exercise, like learning a language or playing an instrument, contribute to brain connectivity and volume improvement.

In summary, experts suggest a comprehensive approach to exercise, including but not limited to deadlifts, provides the strongest brain health benefits.
