Difference between mature and immature muscular systems?

Mature muscular systems exhibit fully developed muscle fibers and optimized neuromuscular connections, allowing for greater strength, coordination, and endurance. In contrast, immature muscular systems, often seen in children or young animals, have less developed muscle fibers and neural pathways, resulting in weaker and less coordinated movements. This difference impacts overall physical performance and the ability to engage in complex motor activities. As an organism matures, its muscular system typically becomes more efficient and effective at handling physical demands.
