If you’re trying to run a faster 40-yard dash, obsessing over becoming more elastic might be a waste of time.
Look at the numbers.
Florence Griffith-Joyner, one of the greatest female sprinters ever, ran an estimated 4.71-second 40-yard split during her 10.54-second 100m world-record performance.
Now compare that to:
• Usain Bolt: ~4.35 (4.22 in ATL unofficially)
• Su Bingtian: ~4.30 (4.1 split during his 60m WR)
These are all world-class sprinters with extraordinary elastic qualities. Elasticity isn’t a gender-specific adaptation. Olympic-level female sprinters are some of the most reactive and elastic athletes on the planet.
Yet their acceleration times are still substantially different from elite male sprinters.
Now consider NFL Combine athletes. Many are 220–250+ lbs, and some run faster 40s than elite female sprinters despite not necessarily having comparable reactive strength or RSI scores.
Why?
Because elasticity isn’t the same thing as force production.
The ability to produce enormous amounts of force relative to body mass, rapidly, is a major differentiator in acceleration.
Tendon stiffness, elastic energy storage, and reactive strength matter. But they don’t replace muscular strength and power.
If you want to get faster, don’t neglect getting stronger and more powerful while chasing some arbitrary elasticity or RSI number.
Elasticity helps you use force. Strength and power determine how much force you have available to use.
