Martial Arts and physical strength: what could progress look like?

Research reviewed September 25, 2026

A little context before we begin

These papers studied specific programs around the world, not Freedom Martial Arts students. The activities, teaching approach, and support differed from study to study, so results do not apply automatically to every martial arts class. They help us ask better questions, but cannot promise what any one child will experience.

What the research found

A Hong Kong trial assigned 44 children with developmental coordination disorder to martial arts or a comparison group. After three months, the training group improved on a particular knee-strength test and a standing-balance measure, but not on balance responses to an unexpected disturbance. The program combined weekly instruction with prescribed daily home practice, a much more intensive schedule than weekly lessons alone.[27]

This paper reports additional outcomes from the same research program as the earlier balance publication in our guide. It should not be counted as an independent group of children. Its selected population and specific tests also limit what it can tell us about strength in every child.[9][27]

Other studies measured different kinds of fitness. The five-country school martial arts trial found improvements in cardiorespiratory fitness and balance. Those results do not establish a general muscle-strength benefit. Similarly, the martial arts study involving adults with Down syndrome found a strength benefit without clear balance improvement. Strength, stamina, and balance are distinct outcomes.[11][20]

Start with a goal beyond being stronger than someone else

Ask your child what they would like to do more comfortably. They might want to hold a position, learn a movement, or take part in a whole activity with an appropriate pause. Their answer makes the goal more personal than catching up with a sibling or being the strongest student. A specific task also gives the instructor something practical to discuss.

Try to separate what you observe from the explanation you first reach for. Hesitating before a movement could mean the direction is unfamiliar, the child wants another demonstration, or the task feels difficult. You do not have to decide the cause yourself. Describe the moment, ask what the instructor notices, and involve your child in the conversation.

Ask how the physical challenge is introduced

Find out how beginners learn a movement before more is added. What does the instructor do if a student needs a simpler starting task or another explanation? How are children taught to recognize a stop cue and practice with care? Ask how the class fits the age group and what participation actually involves. The name of a discipline alone cannot answer those questions.

Discuss any existing movement or health guidance that matters for your child. A research finding is not an individual exercise plan, and an instructor should not have to guess about instructions from a care professional. If a particular movement raises a question, resolve it with the relevant professional before expecting a class to provide the answer.

Notice control and learning, not just harder or faster

Your child may become more familiar with a position before it feels easy. They might understand how to start, remember a cue, or make a small adjustment after feedback. Those are useful signs of learning to discuss, even though they are not formal strength measurements. Ask what feels more comfortable now and which part still needs help.

Avoid turning every attempt into a comparison or a test. A bigger movement, louder effort, or more tired child is not a reliable measure of a better lesson. Listen to the child’s experience and ask the instructor how they decide when to change a task. Any practice outside class should follow appropriate instruction and relevant care guidance.

Choose a routine your family can return to

A realistic schedule matters more than copying the intensity of a study. Consider travel, other activities, and time for rest alongside the lessons. Ask whether your child likes the experience enough to keep exploring it. An activity can be worthwhile for learning and enjoyment before you can identify a measurable physical change.

Review the goal together after some experience. Is the child comfortable asking for help? Do they understand more of the movement? Is there an appropriate next step? There is no fixed research-based deadline for becoming stronger through a particular local class. Keep expectations connected to the individual child, the actual teaching, and the support available.

What this looks like at Freedom Martial Arts

At Freedom Martial Arts, our instructors demonstrate movements, break them into smaller steps, and help students practice from their starting point. Tell us what your child enjoys and what feels difficult. We can discuss the class demands, relevant care guidance, and an appropriate way to begin.
