Functional and/or structural brain changes in response to resistance exercises and resistance training lead to cognitive improvements – a systematic review

This systematic review examined the impact of resistance exercises on brain structure and function and their relationship to cognitive improvement. Resistance training, including moderate-to-high intensity workouts, improved executive functions and memory in older adults. Functional changes were observed in the prefrontal cortex, with enhanced brain activation patterns correlating with better task performance. Structural benefits included reduced white matter atrophy and increased cortical thickness in key brain regions. The evidence suggests resistance training promotes neuroplasticity and combats cognitive aging. However, variations in study design and sample sizes call for further research to standardize protocols and validate findings.

Incorporate resistance training into your routine 2–3 times weekly, focusing on moderate-to-high intensity exercises targeting major muscle groups. This can improve executive function, memory, and overall brain health. While current research supports these benefits, individual results may vary due to study variability. Start with supervised sessions to ensure proper form and safety, particularly for older adults or those new to exercise.
