Wimbledon qualifying opens this week at the All England Club in London, and by the time the main draw begins on June 29, the best tennis players in the world will step onto the grass courts and do something that looks almost impossible: read a ball traveling over 100 miles per hour, decide where it's going, and get their racket there in time.

Defending champion Jannik Sinner will be back. Novak Djokovic is chasing history. On the women's side, Aryna Sabalenka and Elena Rybakina are the names to watch. The level of play is extraordinary. But here's the part that should interest every parent watching from the sideline: the skill at the center of all of it, hand-eye coordination, is trainable at every age.

That matters whether your athlete plays tennis or not. The same visual and motor skills that allow a tennis player to track a 120 mph serve are the same skills a soccer goalkeeper uses to read a shot, a lacrosse player uses to catch on the run, and a basketball point guard uses to thread a pass through traffic.

It's also a big week across the sports calendar. The PLL had a record-breaking performance in Week 5 when Dylan Molloy of the California Redwoods tied the single-game goals record with seven. In the WNBA, A'ja Wilson continues to lead all scorers at 26.1 points per game while Caitlin Clark and Paige Bueckers are running neck and neck in All-Star voting. And in Canada, CFL action picks up Thursday night when the Edmonton Elks host the Winnipeg Blue Bombers. Across every one of those sports, the athletes at the top are processing visual information faster than most people realize is possible.

This week we're unpacking how that skill develops, how to train it at home, and what your athlete can do right now to start building the wiring that separates good from great.

THE SCIENCE:

Hand-eye coordination is not a single skill. It's a chain. Your athlete's eyes capture the ball, the brain processes where it's going and how fast, the nervous system sends the signal, and the muscles execute. Every link in that chain can be strengthened with the right training.

A 2023 study published in PeerJ found that six weeks of stroboscopic training significantly improved complex reaction speed and reactive agility in young volleyball players averaging around 16 years old. Stroboscopic training uses glasses that flicker and block vision intermittently, forcing the brain to predict ball movement rather than track it continuously. The takeaway: the visual system adapts when you make it work harder.

A 2025 study found that hand-eye coordination training improved tennis service skills more than service drills alone. Athletes who specifically trained their visual-motor connection showed greater accuracy and consistency compared to those who only practiced the technical movement. This confirms what coaches have long suspected: technique alone is not enough. The brain has to be part of the equation.

Also worth noting: a 2026 study on fatigue and coordination found that athletes who were acutely fatigued showed significantly delayed reaction times and reduced hand-eye coordination. That's a practical reminder for parents: the last 10 minutes of a long practice or the second game of a doubleheader is exactly when your athlete's coordination breaks down. It's not a mental lapse. It's physiology.

WHAT THIS MEANS FOR YOUR ATHLETE:

This skill develops fastest during childhood and adolescence, which is why youth sports are such a window of opportunity. A 2021 study tracking 258 young football players ages 8 to 17 found that hand-eye coordination, reaction time, and spatial orientation all improved steadily with age and training, with the sharpest gains in the early teen years. The athletes who practiced regularly and across multiple sports showed the widest skill development.

The good news for families just getting started: you don't need expensive equipment or a sports academy. Most of the best coordination drills involve a wall, a ball, and about 10 minutes.

The brain processes visual information, but it needs fuel to do it fast. Nutrients that support nerve conduction, muscle response, and focus directly affect how quickly your athlete reacts. This bowl delivers them all in one meal.

THE BUILD:

THE GOAL:

Serve this 2–3 hours before practice or a game for peak fuel timing. If it's the night before a morning event, this works even better as a prep-ahead dinner. Everything can be assembled cold, no stove required the day of.

WHY IT WORKS:

These three drills can be done in a driveway, a hallway, or a backyard. No court, no net, no equipment budget required. Run through all three in 10–15 minutes, three times a week, and your athlete will notice a difference within a month.

THE PLAY:

Try these three sideline habits this weekend. No equipment, no prep. Just awareness and intention at your next game or practice.

THE STRATEGY:

One of the most underutilized tools a parent has at a practice or game costs nothing and takes about 30 seconds. It's called noticing, out loud, what your athlete did well with their eyes.

Most sideline feedback focuses on the result: "You missed that ball." But the result is downstream of the process. If your athlete tracked the ball well but their footwork was late, calling out the miss doesn't help them improve. It just adds pressure. Spotting the process does help. Saying "I noticed you picked that ball up early, that was sharp" tells your athlete what to repeat, not just what to avoid.

This approach, sometimes called process-focused feedback, is one of the most consistent findings in youth sports psychology. Athletes who receive feedback about their process rather than their outcome develop stronger intrinsic motivation and longer athletic careers. They also report higher enjoyment, which matters more than any statistic when your athlete is 9 years old.

THE PLAY:

Try this at your athlete's next practice or game. Before you arrive, pick one thing to watch for that has nothing to do with the scoreboard. Watch their eyes. Watch where they look before they make a move. Watch how they track the ball when they're not the one with it. Then, on the way home, mention one thing you noticed. Not a correction. Just an observation. Something like: "I saw you watching that midfielder the whole time before you moved. That's smart."

That kind of observation teaches your athlete that you're paying attention to how they think, not just whether they scored. That's a different kind of support, and research shows it sticks.

THE CONVERSATION STARTER:

"When you're in the middle of a play, what are you actually looking at? Where do your eyes go first?"

THE PLAY:

Put on any Wimbledon match this week, even just 15 minutes of one, and watch it with your athlete. You are not watching as fans. You are watching as a team, looking for one specific thing: what the player does with their eyes before they move.

Here is what to look for and talk through together:

After you watch, ask your athlete: "Do you think you could do that in your sport? What would it look like?" You might be surprised by what they know.

THE GOAL:

This kind of sport-watching, where you're analyzing movement and decision-making instead of just cheering for points, is one of the best ways young athletes learn to transfer skills. It works for any sport. If your athlete plays lacrosse, soccer, basketball, or anything else, the same visual principles apply. Use Wimbledon as the teaching tool this week, even if your household has never watched a tennis match.

Wimbledon is a reminder that elite athletes train skills most people don't even notice. The wall ball in the driveway, the reaction drill in the backyard, the 15 minutes of watching film together on the couch: those aren't small things. They are the building blocks of the wiring that makes a good athlete great.

Your athlete doesn't need to be the next Sinner or Sabalenka. They need to be the most aware, most reactive version of themselves on the field/court/rink. And that starts with a parent who knows what to look for, and what to say about it.
