Even when male college sprinters say they feel back to normal after a hard 400-meter race, their leg power is still down by over 7% the next day — meaning their muscles might not be fully recovered even if they feel fine.

After college guys run a really hard 400-meter sprint, their explosive jumping power stays about 10% lower the next day, showing their muscles are still tired even a full day later.

After running a 400-meter sprint really fast, college sprinters aren't as powerful when jumping — especially in the first part of the jump — and this weakness can last up to a full day.

After a really hard sprint, college male runners seem to jump differently for over a day — their muscles spend more time stretching and less time shortening, which might be their body’s way of adjusting after intense effort.

After a regular workout that doesn’t push you to exhaustion, your jumping power bounces back in just 10 minutes—but if you push yourself until you can’t do another rep, it takes at least half an hour to recover.

After running for 24 hours straight, elite runners can't jump as high right after finishing—sometimes less than one-fifth of their normal jump height.
