Keep the amount honest
- Short sprinters usually do not need a dramatic amount to notice a difference.
- More stimulant does not support a better start or better curve running.
- Too much usually shows up as shakiness, tension, or a poor feel.
For 100m and 200m athletes, caffeine only works when it stays smaller than the race routine itself.
Food still matters
- The athlete still needs breakfast or a small top-off because caffeine is not fuel.
- A stimulant on an empty tank often creates fake confidence and weak actual support.
- Hydration still matters too, especially in hot meets.
Test before racing
- If the athlete has never tried caffeine in a training or rehearsal setting, the meet is not the right place to guess.
- The best trial checks nerves, warm-up feel, and how the athlete actually runs.
- A calm race routine usually matters more than a flashy pre-race product.
