Resistance training is often associated with physical strength, but it also has a profound impact on brain health, particularly in the hippocampus. The hippocampus is a crucial part of the brain responsible for memory and learning. While recent studies suggest that resistance training may not have long-term benefits on grey matter volume in older adults, there are still compelling reasons why resistance training can boost hippocampal health.
Firstly, resistance training improves blood circulation, which is essential for delivering oxygen and nutrients to the brain. This increased blood flow supports the health of neurons and can enhance neurogenesis, the process of forming new neurons. Although aerobic exercise is more commonly linked with increased hippocampal volume, strength training also plays a role in maintaining cognitive function by reducing stress and improving mood through the release of endorphins.
Moreover, resistance training can stimulate the release of brain-derived neurotrophic factor (BDNF), a protein that supports neuron survival and growth. BDNF is crucial for maintaining healthy neural connections and improving memory and cognitive abilities. While the direct impact of resistance training on hippocampal volume might be less pronounced compared to aerobic exercise, its overall contribution to brain health through improved circulation and neurotrophic factors is significant.
Incorporating resistance training into a fitness routine can be beneficial for overall brain health, even if it does not directly increase hippocampal volume. It complements other forms of exercise by enhancing physical strength, reducing stress, and promoting a healthier lifestyle, all of which contribute to better cognitive function and well-being. Therefore, while the specific benefits of resistance training on the hippocampus may vary, its role in supporting brain health is undeniable.
