Degenerative changes in the neuromuscular system are an inevitable aspect of canine aging, typically manifesting after nine years of age. These changes include reduced muscle mass, replacement of nerve structures with connective tissue, decreased excitability, and impaired coordination. Such processes can compromise mobility, quality of life, and recovery from injuries in senior dogs.
Aleksandrova and Kryachko (2023) investigated whether physical activity could mitigate these declines. Using electroneuromyography (ENMG), the researchers assessed neuromuscular function in dogs aged 9–11 years. The results showed that dogs participating in exercise regimens demonstrated significantly better preservation of neuromuscular structures compared to non-exercising controls.
The findings suggest that kinesiotherapy and structured activity improve metabolic processes, enhance microcirculation, and support nerve function. These physiological benefits translated into stronger functional preservation of neuromuscular health, reinforcing the role of exercise as a non-invasive intervention to delay aging effects in dogs.
Overall, the study provides convincing evidence that incorporating regular physical activity into the lives of senior dogs can help maintain mobility, promote well-being, and extend their healthy years.
