Athlete Reaction Test | Sport-Grade Millisecond Benchmark

Boxers, sprinters, goalkeepers and tennis players all live in a sub-200 ms reaction window. SERO measures that window directly, free, in 90 seconds.

Why Athlete Reactions Sit Around 150–200 ms

Elite combat-sport and racket-sport athletes test 50–100 ms faster than the average adult after years of stimulus-response training. The trainable window is real and measurable.

How to Use This Test

Run it twice a week as part of your warmup, log the median, compare against your seasonal baseline. Sleep and dehydration show up clearly in the variance.

Does this replace sport-specific testing?

No — it complements it. Sport-specific tests measure context; SERO measures the raw cognitive window.

How often should I test?

2–3 times a week is enough to spot training and recovery patterns.
