Why you crash 45 minutes into training — and water alone won't fix it.
Thirty minutes in, you're playing well. Everything's flowing. Then somewhere around minute forty-five, it goes.
Your reaction time drops. You're making unforced errors you never make. You can feel your thinking get slow and thick, and no amount of trying harder fixes it. That's not fitness and it's not focus — it's a specific, predictable metabolic problem. And once you understand what's happening, it's largely solvable.
Three things move at once
In a long, high-sweat session, three things move at once — and each one drags your thinking down on its own.
Plain water addresses one of those and dilutes another. A simple sugary sports drink addresses one, then hands you a spike and a crash on top of the one you already had. So the crash isn't a willpower problem. It's an input problem — and the fix is unglamorous: the right things, in roughly the right amounts, at roughly the right time.
Electrolytes, and sodium above all
If you're sweating heavily for 45 minutes or more, water alone won't hold the line. Sodium is the one that matters most, and most drinks marketed for hydration contain far less than a heavy sweater needs.
The amino acids behind attention
Your capacity for focus and quick reactions depends partly on neurotransmitters, and your body builds those from amino acids. Branched-chain amino acids are studied for their role in reducing muscle protein breakdown during prolonged exercise. L-tyrosine is studied as a precursor in the pathway that produces dopamine and noradrenaline — the signalling involved in alertness and reaction speed — with research looking specifically at its use under physical and environmental stress.
I'd be careful about how that's usually sold to you, though. The research is genuinely interesting; it isn't a guarantee, and effects vary a lot between people. Treat it as an experiment on yourself: try it across two weeks of comparable sessions and judge it on your actual play, not on how you feel in the first ten minutes.
Carbohydrate timing
You do need glucose — but when decides whether you get a lift or a second crash. Simple sugars taken mid-session are what produce the spike-and-drop people mistake for the crash itself.
Where Igniton actually fits
Let's be plain about this, because it's where a lot of supplement marketing gets dishonest. We don't make an intra-workout drink. We don't make an electrolyte powder. If someone tells you a cognitive supplement replaces sodium and fluid mid-match, they're selling you something.
What we make is IgniCognition and IgniLongevity — a nootropic formulation and a longevity-focused formulation. Both use Igniton's charging process, and the cognition formula's charged ingredients were compared against the identical uncharged ingredients across three university studies published in peer-reviewed journals, supporting focus, mental clarity, and everyday cognitive performance. Igniton is about the baseline you bring into a session — it sits alongside proper hydration and fuelling, and it doesn't substitute for either.**
Former Olympic hurdler Petr Svoboda has credited Igniton products with helping give him the focus to get through a long, uncertain rehabilitation — after an injury where simply walking again wasn't guaranteed — and, ultimately, with supporting his return to competition.
Petr Svoboda has a relationship with Igniton, and this reflects his personal experience. Individual results vary, and no supplement guarantees any athletic or health outcome.**

Frequently asked questions
Why do I crash about 45 minutes into a hard session?
Three things move at once in a high-sweat session: you lose fluid and sodium, you draw down glucose, and you work through amino acids your body uses to build attention-related neurotransmitters. Plain water fixes one and dilutes another — so the crash is an input problem, not an effort one.
How much sodium should a sports drink have?
For a heavy sweater, look for roughly 300–500 mg of sodium per serving, with potassium and magnesium alongside. Check the panel, not the front of the pack — many "hydration" products are mostly sugar. If you have blood-pressure or kidney considerations, sodium matters medically, so ask a professional.
When should I take carbs to avoid the spike-and-crash?
Take complex carbohydrates one to two hours before you train. Mid-session, a roughly 3:1 carb-to-protein ratio is steadier than simple sugar alone, which is what causes the spike people mistake for the crash.
Does Igniton replace an electrolyte or intra-workout drink?
No — and we'll say so plainly. We don't make an electrolyte powder or an intra-workout drink. IgniCognition supports the baseline clarity you bring into a session; it sits alongside proper hydration and fuel, not in place of them.
Do amino acid supplements really help reaction time?
The research on things like L-tyrosine under stress is genuinely interesting, but it isn't a guarantee and effects vary a lot between people. Treat it as a two-week experiment on yourself and judge it on your actual performance, not the first ten minutes.
Fix the sodium first — it's the biggest lever and the most commonly missed. Then experiment with amino acids across a couple of weeks. Then sort your carbohydrate timing so you stop buying yourself a second crash. What's your sport and session length? The right approach for 45 minutes of padel isn't the same as a three-hour ride.
