Interesting video. Confusing a bit to me, because my recent PRs are broad jump (10'3''), SVJ (37.0), RVJ (37.5), and my consecutive double leg jumps are beyond my single broad jumps.   So, according to this video I am good a the tests for hip-dominance, quad-dominance and ankle-dominance, but I perform really poorly (RVJ) in the test which combines all three!

How well does that mat replicate vertec results?  Seems like calibration would be a difficult task for those who jump really high. The difference between a 48'' inch jump and a 42'' inch jump is very very little time in the air because the athlete has to take off and land at a pretty high velocities in both cases, I wonder if that tool is really designed to have the sensitivity or if it is even possible (ie a slight knee bend or change to flight time resulting from touching a surface may throw it off for high-verticals).  

yea like raptor said, maybe you just don't practice rvj often and your form isn't good?  never seen you jump so hard to give definites.   what do you mean your consecutive double leg jumps are beyond your single broad jumps?

the mat is pretty accurate actually, you can cheat it by picking up your knees and landing in like a full squat, but it's harder than it looks.  you would have to consciously be trying to do it in order to cheat.

My point is that it is not uniformly accurate for different verticals.  For example the difference between a 15 inch vertical and a 20 inch vertical is approximately 0.1 second of hang time.  But the difference between a 40 inch and 45 inch vertical is about 0.05 seconds of hang time.  So the amount that you can "cheat" (intentionally or unintentionally) goes up as your vertical increases.  This is coming from a scientist... but non-random noise is always troublesome in any device.  

What I mean is that if I measure how far I am able to cover on four broad jumps (About 40 feet) where I stop between each jump I cover a much smaller distance than if I land and bound for four consecutive jumps (greater than 42).  Usually suggests more reactivity rather than just strength. The end of the video at the bottom has some jumps:

Maybe you have less than developed calves vs your hips and quads. In that situation the difference between the so-called reactive jumps vs. the reset jumps wouldn't be big, or maybe your calves are developed pretty well but your bodyweight x acceleration really really overloads them in the eccentric phase of each consecutive jump - hence they aren't doing too well on the rebound jumps.

I think belly fat actually gives some leverage as far as only squatting is concerned. Another story for athleticism.

You = stronger bench press than me. I'm at 57.5 kg x 5 reps x 3 sets and I'm borderline to failing there.

I'm not doing barbell bench pressing anymore though... too dangerous. I'm doing DB bench presses now.

Have you ever did hip thrusts, Scooby?

How good are your Romanian Deadlift numbers? In general, how good are you at hip-oriented exercises?

With the weather warming up, i'm feeling good about being lean, the idea of a summer without being fat is a novel thing.

You're in Australia?

What's your personal best for the sprint i.e. 100m?

sup man, not idea.. never had it officially timed.. i imagine at one point i was under 12 seconds lol, no idea though.

pc

it doesn't have to be official, i thought that you're best was probably 10.5s

It was about 10.3s back when he weighed 210 lbs.

Simple : you increase your squat at a faster rate than your increase in bodyweight.
