Heavy squatting as well as heavy lifting in general would kill them as sprinters, especially if they did it on regular basis. As for lifting weights they mostly do with light weights 25 - 40 % of their personal best, for explosive power, they do lots of plyometrics too. However, I wouldn’t be surprised if they don’t even know their personal best in certain lifts.
And such a competition who lifts more weight is completely irrelevant, because they aren’t powerlifters not even close… they are runners… they have to be very lean, explosive, fast… and during competitions they sprint with they own body weight, they don’t compete sprinting with a 150 lbs bag on their sholders.

It really depends on what type of sprinter u are. Someone like Gatlin might squat more, which probably means that he is more explosive, which means he will have a better start, and will be faster in the first 30 meters. But the first 30 meters aren’t the whole 100 meter race… top speed comes into play, and the strongest and the most explosive sprinters don’t always have top speed. Look at someone like Bolt or Carl Lewis. They are more or less “springy” sprinters that rely more on reactive ability, technique, and stride length. But this does not mean that they shouldn’t squat. I agree with the poster above that if Usaine never squatted, and starts to squat now, he will break his own PR. It might not have as much effect on his top end speed, but if he can become more explosive coming off the blocks or the first half of the race, and is still able to hold on to his top speed, he might just be a faster 100 meter dash sprinter.
There’s a reason why all the Olympic sprinters have such high verticals and can probably sprint just as fast as sprinters coming off the blocks up to 30 yards. More squat = more strength… more strength means potentially, more power. [/quote]
surprisingly, top speed is rather irrelevant at the elite level. data suggests sprinters (humans?) have plateaued their maximal velocity (for now?).
what is more relevant is maintaining that speed… speed endurance. bolt is very good at this, which is why it appears that he has a faster top speed, which I assure you he does not.[/quote]
sorta disagree, he has to have faster top speed and speed endurance in order to be that good, just from watching the 100m races at least. Having run 100m and 200m, it is not that hard to maintain top speed in 100m once you reach it for a well trained sprinter, but speed endurance comes more into play in the 200m.
Also how is top speed irrelevant at the elite level? That’s like the most important thing IMO.

Honestly, I’ve heard that before, but I read a paper on the illusion of top speed in elite 100m races and since then I did not reconsider.
You have caused me to reconsider. I went to the data myself this time. Thank you for the propulsion.
Here is my new conclusion:
Top speed and maintenance of that speed are of “equal importance” because they form a rudimentary equation of 100m performance (time); thus, the fluctuation and/or individual differences in these values can counteract one another.
For instance, I am assuming the following:
- Reaction times are equivalent
- All competitors’ velocity will peak in the 60-80m range
- All competitors will slow down nearly immediately after peaking
Given these premises, there are multiple ways to achieve the same performance:
a) Reach a higher top speed and regress faster
b) Reach a more “average” top speed and better maintain it
Thus, there can be a variety of performance styles. Usain Bolt is dominant because he can be the fastest AND the best at mitigating speed fall.
Top speed = 26 mph +/- 1.5 mph for most elite sprinters. Usain Bolt set the high in 2009 @ 27.79, which he has not really gotten close to since. Close being relative, naturally…
Also, you are wrong, it is IMPOSSIBLE to maintain true top speed in the 100m.
Like I said, the general trend is this:
a) accelerate until the 60m mark
b) hit a top speed in the 60-80m section
c) decelerate
Thus, the factors are:
a) quality of acceleration
b) top speed, length of maintenance
c) rate and impact of deterioration
IF our subjects accelerate equally and deteriorate equally, then top speed simply shifts the function, while maintaining its basic shape. In that sense, top speed is most important. However, these assumptions are not the case. Usain Bolt is not the fastest in every race he wins. An odd statement, I know. This is also true: Usain Bolt can be the fastest in a race he does not win.
I think he dominated because he had an excellent combination of top speed and speed endurance. It is arguable that Tyson Gay was better at accelerating and maintaining his speed, but that it was insufficient to win in that case because 98% of Bolt’s top speed was greater than 98% of Gay’s top speed (in the 2009 race).
While that may sound like total support of “top speed is king”, it isn’t. Just because Bolt is currently king doesn’t mean it is inconceivable that he could be beaten by someone with a lower top speed but a lesser rate of decay… Hell, it has happened already! Lol!
