We’ve all seen it. A teenager hops out of the car for practice, moving in a near-total daze. They’re physically there, but mentally? They’re still stuck in the digital world of a TikTok feed or a high-stakes mobile game.

A group of successful rowing coaches recently discovered a common thread: when they banned cellphone use on the drive to practices and games, the “haze” vanished. They found that without the phone, athletes were ready to go the moment their feet hit the grass. With the phone, the first 15 minutes of practice were essentially a wash.

As it turns out, science confirms what these coaches and parents have seen firsthand.

The Science of Mental Fatigue

A systematic review by sports scientists recently looked at how “cognitive tasks”—like scrolling social media or playing video games—affect athletic performance. The results were clear: performing these tasks right before sports negatively impacts skill and decision-making.

Here is what is actually happening to the brain and body:

• The “Invisible Weighted Vest”: The study found that while an athlete’s objective motivation didn’t drop, their perception of effort increased. This means the workout or the game actually feels harder than it should. For athletes where “feel” and “pressure” are everything—like staying on pace during a 2K erg or maintaining a steady rowing rhythm—this mental fatigue can make you significantly slower without you even realizing it.
• Speed Stays, Accuracy Strays: Interestingly, mental fatigue doesn’t usually slow your raw movement down, but it destroys your accuracy.
  • Soccer players made the same number of passes but with more errors.
  • Defenders missed tackles they would normally make.
  • Basketball players saw a spike in turnovers.
• The Coxswain Effect: Mental fatigue specifically hurts “visual search strategy.” In team sports, this means players become less aware of where their teammates are compared to their opponents. If you are a coxswain or a point guard, your ability to “see the field” is the first thing to go when you’re mentally drained.

The 135-Minute Rule

The “deleterious effects” of this mental fatigue aren’t a quick fix. Research suggests the haze can last anywhere from 60 to 135 minutes. If your athlete is scrolling on the way to the field, they might not truly “wake up” until the game is nearly over.

How to Protect the “Mental Edge”

The good news? Athletes are actually very good at sensing their own mental fatigue—if they pay attention. The study noted that an athlete’s subjective feeling of being “drained” usually happens right before their performance starts to slip.

For parents and athletes in our Woodinville and Bothell communities, here is a simple “Pre-Game Protocol” to try this week:

1. The Music Compromise: Headphones are fine! Music can pump you up without the heavy cognitive load of processing fast-moving video or social interactions.
2. The “Car Mode” Rule: Make the drive to the game or the boathouse a phone-free zone. Use that time to visualize the game, talk through strategy, or just let the brain rest.
3. Trust the Feeling: If you feel mentally “fried” after a long day of school, acknowledge it. Take five minutes of quiet breathing before you start your warmup to reset the brain-body connection.

Peak performance isn’t just about how well your joints move or how strong your muscles are—it’s about how clearly your brain can communicate with your body. By putting the phone down, you’re giving your nervous system the best chance to succeed.

Peak performance isn’t just about how well your joints move or how strong your muscles are—it’s about how clearly your brain can communicate with your body. When that connection is clouded by mental fatigue or physical stress, your reaction times and accuracy pay the price.
