<p>Research has demonstrated that engaging in regular exercise has the potential to enhance cognitive function, promote neuroplasticity, and mitigate the likelihood of experiencing cognitive decline. The underlying mechanisms responsible for these effects are intricate and encompass various pathways, including the interaction between neurogranin and calmodulin. The activation of calcium signaling pathways is a significant mechanism through which regular exercise facilitates the treatment of age-related diseases. The activation of neurogranin and calmodulin induced by exercise can provide protection against neurodegeneration by promoting neuronal survival, mitigating oxidative stress, and improving mitochondrial function through the regulation of calcium homeostasis and energy metabolism. In addition, there is evidence suggesting that engaging in regular exercise can lead to an upregulation of neurotrophic factors, specifically brain-derived neurotrophic factor (BDNF). These factors are crucial for the survival of neurons, the plasticity of synapses, and overall cognitive function. Researchers have discovered the involvement of neurogranin in the regulation of BDNF signaling, underscoring its significance in exercise-induced neuroprotection and cognitive enhancement. The current work offers valuable insights into how neurogranin/calmodulin cooperation, facilitated by regular exercise, promotes the treatment of aging-related diseases. The results suggest that regular exercise could enhance memory, learning, synaptic plasticity, and resilience to neurological damage; promote recovery after brain injury; and treat aging-related disorders such as Alzheimer’s disease.</p>
