Study finds weight training not only strengthens muscles, but also boosts brain function

Weight training is not just about building muscles; it also pumps up the brain, according to a recent study published in the British Journal of Sports Medicine. The research found that resistance training, such as weightlifting, not only strengthens muscles throughout the body but also benefits brain health by improving glucose processing.

The study revealed that engaging in resistance training can lower the risk of various medical disorders, including cardiovascular disease and diabetes, by enhancing the brain’s ability to access and process glucose. Prolonged unstable blood sugar levels can lead to inflammation and insulin resistance, which can impair brain cell function and cause long-term damage. However, a single session of resistance training was shown to decrease blood glucose and insulin levels for up to 24 hours.

To help beginners ease into weight training, NYC-based fitness coach and personal trainer Claudette Sariya shared six basic bodyweight exercises that lay the foundation for more advanced movements. These exercises include squats, hinges, pushes, pulls, lunges, and carries, which help individuals develop strength and stability before progressing to using weights.

In addition to improving glucose metabolism, exercise has been linked to increased brain volume, as suggested by research published in the Journal of Alzheimer’s Disease. The study analyzed brain scans of over 10,000 individuals and found that regular physical activity, even as simple as taking a few thousand steps a day, was associated with larger brain volume.

Brain volume is a key indicator of brain health, with lower volume being linked to cognitive decline and potential dementia. Maintaining or increasing brain mass through exercise could have neuroprotective effects, according to the researchers. Even moderate levels of physical activity, such as brisk walking or playing sports, were shown to have a positive impact on brain health.

Participants in the study who engaged in moderate to vigorous physical activity had more brain mass in regions responsible for memory, information processing, and cognitive function. The findings support the growing body of research highlighting the numerous benefits of exercise for both the mind and body.

Whether it’s weight training, walking, running, or playing sports, staying active has been shown to have a profound impact on brain health and overall well-being. By incorporating regular exercise into their routine, individuals can not only strengthen their muscles but also boost their brain function and potentially reduce the risk of cognitive decline in the long run. So, grab those dumbbells or lace up your sneakers and get moving for a healthier body and mind.
