The term for the body's physiological adaptation to exercise is exercise adaptation. This process allows the body to respond to increased physical demands by enhancing its efficiency over time. Key adaptations include improved cardiovascular function, increased muscle strength and endurance, and enhanced metabolic processes. Regular exercise prompts changes such as increased mitochondrial density in muscles, improved oxygen transport, and better neural recruitment strategies. These adaptations help individuals perform better and recover more quickly, ensuring continuous progress in their fitness journey.
