So I have been loading videos into this web app that allows you precisely tag takeoff and landing points of a video and calc hang time and vertical etc.
https://www.thehoopsgeek.com/measurement-app/#!
And a lot of jump mat videos are so inflated it's crazy.
That 47.1 vertical vid from a football combine is only 41 or so inches based on hang time...
I wanted to measure a lot of popular vids, on Youtube and instagram but they tend to slow mo the jump after takeoff... blah...
Clarence's jump back when he was 80kg, with that 200kg squat is a legit 40 inches or so on the app. Not bad for a non vert training person.

another vid I tried was Rugter's Dunker's vertical on a vertec, which was supposedly 40 inches, I only got 30 inches....

Someone who trains to a 2.5*BW ATG squat, for whatever reasons, using whatever methods, with whatever other variants, either he knows it or not, he also trained himself for(to) a top-class vertical jump too.
;D :lololol:

Clarence was more an olympic lifter back then and did a bit of tricking, but I doubt he practised running jumps as much as BBall players/aspiring dunkers do :)

I was looking at that site last week! Your thoughts on accuracy in regards to your own jumps/vids?

Pretty close, but with lower jumps and 30fps the swing to either side of the measurement is quite a bit larger. Most are within 2-3 inches
Also I think timing from feet flat to feet touch landing is more accurate as the toe off adds jump height
see
The analysis might underestimate your vertical jump if you take off and land on your toes.
Since I land on my toes, this under estimates my jump a bit.
It matches up for me when I time from 1-2 frames before my feet leaves the ground and flat feet landing
-
Got a 43.7 inch jump on the above vid with the proper measurement settings now. :ibjumping:
From just before the feet leave the ground, to flat feet landing
accurracy will vary by up to 3 inches either way due to 30fps

Rugter's Dunker VJ is now 35.5

Johnny Candito - 35 inches
55 inch box jump from a stand still. Used car due to lack of resources. Video shows what a 515 pound squat can do for your vertical leap. My vertical is around 36 at a stand still. I am 5'7" 175lbs

40-43 inch, jump mat claims 47.....
http://www.youtube.com/watch?v=lgkCxnSHV7w
Sammy Coates 42 inches - Jump mat says 45
see 1:02
http://www.youtube.com/watch?v=rP7m61gGmP4
44 claimed, got 43 on last attempt, so close enough
http://www.youtube.com/watch?v=5eJGmgRPBtk

All his jumps are around 37 inches, 40 inches tops, there is no 44 here...

vert inflation, what else is new ;f
i don't trust any jump mat numbers.
and hardly anything passes my "eye test" lol.
you know a legit 35, 40, 45, 50 etc when you see one. massive changes in float every ~5".

I really want to time one of Riley Smith's recent running jumps, but they all have slow mo :/
-
Got 48.3 inches on this one :ibjumping:
1 sec hang time
-
48.7 inches, actual jump probably would be higher due to him hitting his head and reducing the hang time!

imho he's got the most float out there right now. some of these jumps are unreal.
-
also worth posting. crazy.
-
always with the slow mo :/
I'm gonna do some of Gediminas Žitlinskas dunks, he gets up
-
Dang I got 57 inches on this dunk.... 1.09 sec hang time, maybe he got a boost from his hand hitting the rim on the dunk
Even measured from tip toe takeoff, to tip toe landing 1.05 sec hang time = 53.6 :o
But at 5'9" and this head height to rim, it's sure up there!

isn't it possible for this method to give inaccurate results if you leap off with straight legs but coming down can be delayed by bending your legs and therefore increasing your air time.

Yes, but not many people do that naturally, as it hurts a lot :)
As your far stronger when you absorb the forces with a straight leg first
Also you use your judgement when setting the start and end points on the app, it's quite obvious when going frame by frame if someone is sand bagging

Got 48.3 on this old T-Dub ceiling touch jump
http://www.youtube.com/watch?v=R2-SWEkN63A
-
On first jump, 12 feet touch I got 49.4 inches
48 to 51.5 on second jump
48.4 to 51.7 on third jump
51.7 on 4th jump
52.6 on 5th jump
But on his highest 6th jump, it was slo mo'ed... so it's definitely 52 or higher
http://www.youtube.com/watch?v=MmVIbx80MvU
-
No slow mo on this jump, got around 51 inch
from flat foot takeoff to flat foot landing.
Since he is around 5'9" it looks about right as well
-
Measuring verts is a tricky topic. There are so many methods.
Measuring the height your head travels should be close to your real vert, which in this case he is 5'9 and the rim is 10 ft and let's say he got top of head around 2 inches above rim. That would be a vert of 53, so 51 sounds right.
But for me my head is 3.5 inches away from touching my ceiling 27 inches away equalling to 23.5 but according to flight time it's 17 inches.
Also using vertec does not really seem accurate as you measure flat footed but when you jump you toe off, so maybe starting reach should be measured on tip toes.
-
vertec measures displacement power, but standing on tippy toes requires no power :)
