Abstract: Introduction: Aging has been shown to be associated with decreases in brain and muscle tissues, accompanied by dysfunction in cognition and functionality, respectively. Resistance training (RT) has been widely recommended to mitigate muscle loss but its effects on brain tissue are still unclear. Purpose: This study verified the effects of 12 weeks of RT on gray matter density in elderly. Methods: Seven participants (four men and three women; 61.3 ± 2.8 years; 68.7 ± 16.5 kg; 161 ± 12 cm) had the brain anatomy and thigh cross sectional area obtained through magnetic resonance imaging (MRI) before and after RT. Gray matter density was then separated and compared between pre and post exercise intervention. Results: Data showed that RT promoted increases in gray matter density in the posterior and anterior lobe of cerebellum, superior frontal gyrus in the frontal lobe and anterior cingulate cortex in the limbic lobe (p < 0.001). Additionally, RT also increased thigh cross-sectional area and muscle strength (p < 0.05). Conclusion: Our study indicates that resistance training may be an alternative intervention to improve neuronal density in brain regions related to motor control and cognition in the elderly.
