If you've been around CrossFit for any length of time, you're bound to hear someone talking about intensity. What do we really mean though? How much yelling you do during a WOD? How big of a sweat-angel you leave? Wicked amounts of stabbing pain?

Nope. What we're really talking about is your power output:

P = \frac{W}{t}\,

Power = work / time.

Question: Is the highest power output gained by you crushing yourself and doing the WOD rx'd or is scaling a better option? If so, when? How can you tell?

On another note -- this classic calculation is only good for when work is involved, which means we can only figure power for lifts, pull-ups and the like. When you kick your butt in a run -- this does not work.

So - how can you figure it without that vertical component required for "work" to be accomplished? Well...

  • Velocity = Distance ÷ Time
  • Acceleration = Velocity ÷ Time
  • Force = Weight × Acceleration
  • Power = Force × Velocity

OR

  • Power = Weight × Distance2 ÷ Time3

p is in watts. Weight is your weight or the weight of the runner / test subject.

It's not super precise -- but can give you a pretty good indication of things.

Geek Out with your sprint times from Sunday. Physics and math peeps -- feel free to go all XKCD.

Sactown Throwdown Results PDF Print E-mail

8th out of 31 teams! Wow! Top ten on the first try!

The Throwdown Team of Alex, Libby, Nigel and Sarah P hit it hard and had a blast. Everyone just turned in super performances. I can't thank them enough for their efforts! I also think we're all a little more stoked for Sectionals and Affiliate Cup and future throwdowns than we were before. The fire in the belly is turning into a blast furnace. Yeah!

A big kudos goes out to Maiya, Brian, Bob, Carolyn and Tara for coming out to show their support and to Max for holding down the CFD fort when we all know he'd rather have been at the Throwdown.

More photos and maybe some video to come in the next week or so when the CF Journal / CF.com folks get everything sorted.

The CFD Throwdown Peeps!
