Physics/Strength Training/Leonard Fournette Question
Posted on 6/27/16 at 6:39 pm

Power Clean
Mass = 330lbs or 726kg
Either Velocity = 1.2m/s or time = 1.2s, not sure which. Can you solve it both ways
Is that enough to give you Power output?
Do you need acceleration? Something else?
Reason I asked is because my lil bro got to watch mr. Fournette go beast mode on some PCs today with Moffitt and sent me a text saying he "PC'd 330lbs in 1.2". He was thinking 1.2 meant seconds but that's pretty irrelevant for an "end game" measurement. figured it had to mean velocity, but that doesn't account for the 330. And now I'm curious about what kinda power output that was.
FYI - It's measured in Watts for things like this if that helps you brainiacs

Power is gonna be force times displacement divided by time.
Force is mass times acceleration.
You can do the math. I'm lazy.
Answering your question: acceleration would be an ideal piece of information to do this problem.
Eta: the 1.2 is probably the time it took. Which could give you average velocity, but not really acceleration.

Yeah that math is great but no less than 10 guys on the OT did 330 for 8 reps in .01 secs

The correct answer is Juneteenth.

Id rather calculate these.

In an interview with Moffitt in which he spoke about the strength and conditioning test of all the players coming into summer, he said Fournette had a good mix of power and strength. He said that Joe Addai was the most powerful back LSU ever had and that Michael Ford was the strongest back LSU ever had.

frick you and your magic

Bout three fiddy.

If my math is right, he generated around 195 Newtons of force. Now, I don't know what to compare that to

First off, Schmelly, your lb to kg conversion is wrong. 330 lbs is about 150 kg (not 726 kg).
Now for today's physics lesson...
Power is Energy/Time
The energy supplied by the lifter has to equal the final potential energy of the weight, which is given by:
Energy = Mass * Gravitational Acceleration * height
As a power clean lifts to the shoulder, this should be about 5 ft high (or 1.5 m) on a 6 ft tall football player. This gives:
Energy = 150 kg * 9.8 m/s^2 * 1.5 m = 2205 J
The power is then:
Power = (2205 J) / (1.2 s) = 1837.5 Watts which is about 2.5 horsepower.
- from your friendly neighborhood particle physicist
FYI - That means 660 clones of Fournette would be enough to supply the 1.21 gigawatts of power needed for Doc Brown to go back to the future.
Mountain Tiger is correct... Should be 660,000.

The laws of physics don't apply to Buga

fwiw, the math doesn't translate exactly to the field.
There's dozens of small data points from how he swings his arms to the relative balance of using quads vs hamstrings while running, to the way his feet contact the ground (and how much force is lost into the ground vs how much is preserved in forward momentum), to his core and shoulder strength, etc... All these things point to how efficiently he uses his strength/power on the field.
It would be impossible to track all those data points casually... If you had a lab and ran a series of tests over and over, maybe you could. But you can sort of get a sense of how efficient athletes are by watching them. Tyrann Mathieu comes to mind as perhaps the best example of an athlete with such outstanding body control that there seems no wasted movement. If he's making a tackle or stripping a ball, every part of him seems unified to that purpose. When LF hits his groove, he's definitely outstanding in that regard. But I don't know how you'd be able to assess that accurately.
