I have uploaded three clips showing Gardener running 6.51. The first one is the race itself, the second one shows the runners in slow-motion from the side and the third one shows Gardener in slow-motion from the front. The quality is a little rough.

Jason has alot to work with. Very relaxed and very smooth. The other racers need to relax a bit and concentrate on turnover and not so much raw power. There seems to be too much pushing down into the track with most of Jason’s competitors. It could just be the time of year. They all want to see how much faster lifting weights has made them.
Jason seem to be trying a bit hard himself by staying low during his acceleration, and therefore seems to fall a bit apart upstairs and also start toeing into the track instead of relaxing and stepping over.
I am surprise at how small he looks. I would have guessed that a person running 6.46 would have more of a muscular built.
Great! Thanks! First time I ever see Gardener run. Very nice piece of running. BTW theone I also always imagined him as having legs like tree trunks, a complete animal to run so good indoors but too heavy and lumbering around outdoors! Can’t understand how this guy can’t run 9.8x, he looks better then Tim.
It’s all about reaching your perfect bodyweight/strenght ratio. I know Sprinting is not highjumping, but think about it: a highjumper jumps about +1cm higher for every pound he loses. And for a sprinter it’s very easy to gain too much bodyweight, too.
I saw more (seriously training) athletes with too much muscle mass than athletes with strenght deficiancy. A lot of guys get fooled by the fact that some athletes simlply grow muscles very fast (Mo, Ben, …) but tend to lose the focus on speed - growing big is more of a side-effect than the guarantee to get faster…
Jason become a specialist in Indoors,
his “lean” body has perfect bodyweight/strenght ratio to 50m or 60m races,
he is light but strong,
otherwise, he hasn´t power to sustain speed over 100m,
look his 1st 20m, he just go out from blocks usen´t a pattern of “lower” uper body like does MG, JD and others HSI, even Justin Gatlin.
Jason has a capability to attain max v with few steps, like nobody, this is probably because of lot stand start train,
look his last 10m, he decrease as a on/off button.
I was watching today the 60m from last year - Indoor World Champion -
where JG beat JG,
Justin Gatlin won that race with a 6.46,
after that, JG ( Jason ) he´s become better & better day by day,
but, we´re talking about 60m races right ?
I’m sorry but can we please get an interpreter for Flying??? LOL, sorry buddy. 
All right,
free ok !!!
It seems like that extreme forward lean in start/acceleration phase makes you reach MaxV a little later.
Ben (or Jason in the Video) do not do accelerate with that extreme forward lean and seem to reach MaxV earlier in their races. (In- and Outdoors)
Anyhow - it makes no sense reaching your top-speed at 60-70m in a 60 meter race.
Anyone got a video of Mo performing indoors (i have to admit I never saw one of his indoor races) maybe he accelerates different, or maybe it simply proves me wrong…
Don’t have a video of Mo indoors, but I remember seeing 60m races in which he was just becoming completely upright at the finish line.
Take a look in Jason´s set position, his hip & neck are almost in a straight line
Jason has since gone 6.46s (equal ER).
I believe his limiting factor over 100m is max velocity. If you’ve seen the IAAF breakdown of the World Champs from 1999 (Jason’s best year) his top speed was the lowest of all the finalists - 11.1m/s(??).
Sounds interesting. In this case split times of one of Mo’s 60m which clocked around 6.40 would be very interesting…anybody got some data, please?
