Why Starting Martial Arts and Swimming Early Helps Children Build Stronger Brains

Did you know that the brain goes through a major “pruning” process around age 11? According to Raising Mentally Strong Kids by Daniel G. Amen and Charles Fay, “Connections that are used repeatedly in the early years become permanent, while those that are not used are pruned.” In other words, the brain literally trims away pathways it doesn’t need, making the circuits that remain more efficient. This is called the use-it-or-lose-it principle, and it has a huge impact on learning new skills later in life.

What does this mean for your child? Simply put, if a child doesn’t engage in certain activities early on, their brain may prune the neural connections that would have made those skills easier to learn. For example, children who don’t play sports may find balance, coordination, and agility harder to develop later. Likewise, kids who don’t explore an activity like swimming may struggle with those skills when they try them as teenagers or adults.

This is why activities like Karate, Jiu Jitsu and swimming are so valuable. Martial arts helps children develop coordination, focus, and strength, while also giving them the skills to defend themselves or a loved one if ever needed. Swimming, on the other hand, builds endurance, balance, and full-body coordination, while equipping children with the ability to stay safe and survive if they ever fall into water. Both activities challenge the brain and body in ways that create strong, lasting neural connections.

Starting these activities early gives children the chance to form permanent pathways in the brain that support learning, problem-solving, and physical skills. The more they practice, the more efficient and resilient their brain becomes. Even if they decide to pursue new activities later, having these foundational neural connections makes learning faster and more enjoyable.

Parents can think of early childhood as a critical window for brain development. By encouraging children to try Karate, Brazilian Jiu Jitsu, swimming, or other physically and mentally engaging activities, we give their brains the stimulation they need to grow strong and adaptable.

In short, the brain works best when it’s exercised early. Martial arts and swimming aren’t just fun—they’re investments in your child’s lifelong ability to learn, move, stay safe, and succeed. Start today, and help your child build a brain that’s ready for anything.
