hey what's up everyone morey croson here from the performance lab in California and we have another
new breakdown for you today and it is gonna be a concentration on arm speed and what is the
the big importance of arm speed and obviously I mean it's a it's a big thing that you ought
to be able to do effectively in order to run at a the highest level and really I think the
the biggest thing that helps you do is really maximize your turnover how fast you're moving
your overall legs and so what I did here is this made a quick little comparison between the fastest
guy here in the race would just Trayvon Bromell as if you guys are subscribers for a while you
guys know big fan I Trayvon Bernal how he runs as in comparison to the guy that end up coming
in last place in the race and what I did there is one legit overall how many arm swings did
drove it Trayvon Bromell do and did 48 of them all together and then you're the guy that came
in and Lassen in Lane eight here he got 46 and then the next thing is how much time did it take
to get to ten arm swings so for Trayvon Bromell you can see one two three four you can get to
his first floor very very quickly they're five six seven eight nine ten right 106.8 seven so
we got one more little mark there and so that was the the first ten in the arm swings and
just about how fast you get to ten and how much overall distance are you getting when you get
to those those ten-dollar swings just because you know that by moving those arms faster that
just makes it so again your turn over your legs start moving faster in combination with that so
and and you don't want to end up limiting your range of motion when you're going through these
arm swings you want to just be putting a big concentration on speed as you're going through
your arm swings so if you're limiting your ability to actually create power within your lower body
because you're just super short with your arms that's obviously a problem what you want to be
you use your arms to allow your your body to work in sync with each other to make it so you know
your upper body's really driving back to make it so if you look what if let's say your right
arms driving back that helps you in getting full extension on your left leg as well as when it's
driving forward it helps you get full flexion out of your left leg so by by maximizing the endpoint
of your arm swing deflection in the extension going alway back on our way forward what that
does has helped you in generating better force in the lower body in flexion and extension so
just maximizing that it's going to be crucial but then you also have to have fashions because
you're doing that doesn't mean you're necessarily optimizing your run because you're doing it slow
and out of control then that's actually not going to impact yours but you see 106 here and then 106
9 7 is when the guy here in Lane eight end up getting to its are already by this cease point
one behind them in terms of where the overall arm swings are and so that's gonna translate over and
that's just in probably the first maybe 12 meters so then we'll go to the next 20 W went to 20 was
till 11 I'm looking at rig on 12 13 14 15 16 17 18 19 20 108 point 8 here is where he ended
up getting to 20 arm swings and then you could see again so he's still that's 19 fir'd for him
he doesn't get to 20 until he gets this arm all the way back so he's a full arm swing and also
full half stride behind him and so that ends up shutting off about 2/10 of a second in terms of
the difference in where they're at and the current run this is that at 20 hand swings that the actual
place in the race looks like it's getting close to about 30 meters there and in terms of where
they're at and so that ends up being a big impact as now as time goes on you know this this number
continues to just separate more and more and more in terms of the speed that Trayvon Bromell is is
moving his arms to make it so now you know he ends up being two whole arm swings infernum oh by the
time the the race is over those two whole arm swings may be so he's maximizing you sports just
that mcclure so you got to be able to maximize your length and your actual stride as well as
being able to move your arms at a very very high frequency rate especially for those first 20 arm
swings if you're not moving your arms fast at the very beginning there it's gonna be very very
difficult for you to get into the right posture it's gonna be very very difficult for your body
to open up your stride to open up to you for you to be able to really and truly maximize your run
so really being keen on how your arm swing works and really you know that again at the beginning
of the race you got to be able to implement this information to when you're starting off because
if you're already if you're trying to you know maximize your arm swing at the end you know I
think you're that's gonna be important but getting yourself into the correct posture getting yourself
going into top speed those are the things that your arm swing really really be is able to impact
and then once you're at your top speed you just use your arms to really maintain that posture
and maintain that that efficiency within your body to make it so you can transition from your
into your top-end speed you know through your transition page and a few times be alright we
have a lot of different things that you guys can you know sign up for or participate in with our
programs you can get individual breakdowns we have speed programs we have different things that we
offer for you know athletes that are looking to get faster we'd be happy to help you out if you
have if you're interested in learning a little bit more you send us an email we have links below or
you just sign up for the programs you also have wooden tool for that there's always if you want
to reach out and ask any questions you can reach out to me at Morey mo re Y at your performance
