it's a absolute pleasure to be here thank you and i wanted to uh clarify that amateur vision so you've seen
00:00:05
a lot of real p. h. d. researcher to know what they're doing but please grade on a curve
00:00:10
um also i like to uh acknowledged boris and um
00:00:14
frederick in this wonderful organisation that they've started
00:00:17
this should not be the end of this process or should be the beginning
00:00:21
as far as young athletes in differences hoping many viewer enthused in
00:00:24
can i keep getting involved in and stay in touch with boris about how you can assist
00:00:29
we have an interesting problem in the night state i'm involved in a number of organisations to try to help
00:00:35
uh improve uh um you sports in in in the culture in the state
00:00:40
um but it was to all that i make uh actually no money so this is a passion i think for many of us
00:00:46
uh i've been literally across not just the country but around the world speaking on this particular topic and
00:00:51
um anywhere from uh you know many place in the states in canada and i was c. n.
00:00:56
and most recently you know i'm here actually in beautiful switzerland so
00:01:00
this is an international global issue that we're talking about with this the sports special station if you
00:01:05
look at the concert to uh keep kinda giving some of the same messages in different places
00:01:09
we've had probably about a hundred fifty media release is uh that it had a talk to media on this particular topic and
00:01:16
a lot of it maybe slanting asked in one direction maybe in another and it's hard
00:01:20
to say is this real or fake news is our president would say um
00:01:25
and you know are we you know where the greatest in everything in
00:01:28
us and so are we the greatest it ruining young athletes in
00:01:32
you know it's nice to follow some early but maybe we're not the people that should we should be role modelling after
00:01:37
um because of all these talk sometimes i'm asked to just going give a talk and and how
00:01:41
score special vision is bad but i think it's really healthy debate and i kind of
00:01:46
on a place with one and this one and and let all this gotten look at the data and and decide when when is it
00:01:52
bad when is a good and number every athlete special is at some
00:01:55
point of their lead and not all athletes have negative consequences
00:02:01
and so we wanna see it it's a really a benefit early specialised training
00:02:05
and you know do these wrist out weigh the benefits in certain situations
00:02:09
and then maybe we should look at it from a sport specific model could is different from one sport to another
00:02:15
sports special ration should be looked at as a continuum from starting with your
00:02:19
physical later seen in motor control either previous speakers were talking about
00:02:24
to deciding whether should specialist and then continue on with the lead actually development
00:02:28
but is that interrupted by specialise in a sport noted from the questions we'd like to be able to answer
00:02:35
um in the b. d. s. m. issue and make sure the young athlete uh i wrote a
00:02:39
little bit about sports special station the biggest risk not being the individual risk of the athlete
00:02:44
or rather what it does to all the other athletes to do become disengaged with physical activity in
00:02:50
sport the seventy percent number that we heard earlier is the same number that i use
00:02:55
in particular but thirteen years old it's is a very disturbing number uh that we
00:02:59
need to we need to work on it seventy percent make it more appealing
00:03:03
and so maybe with a different approach to sports special edition first increased physical activity in more kids
00:03:10
increase use sports participation and improve performance
00:03:14
that's our ultimate uh reverse pyramid
00:03:17
in where sports special edition fit in this does it help me to these things or the harm them
00:03:22
and i think that's the big picture approach that i try to look at now with this concept
00:03:27
and and so then the question for you is are you listening to this talk
00:03:31
trying to influence maybe the million young a kitten young athletes out there
00:03:35
or you train design recommendations for the one in a million and that's the question that
00:03:40
you should be asking yourself in the in the people that you take care of
00:03:44
i'm more of a participatory model thinker and i want to include more kids playing if possible
00:03:50
use porches crazy uh in america i'm you have kids at such a young age is
00:03:55
doing all sorts of things word pairs are pushing them like this guy there this data over there just
00:04:00
making it can't do you know whatever you know it two years old just trying
00:04:04
to get a tennis ball and we actually that's i think that's in me
00:04:08
wait a second wait but that might cheer even be roger fatter he's defending your get my kid
00:04:13
is always better high there's an exception here i think my kid is gonna be the best
00:04:17
next best tennis player so it's not just you know so that's the problem
00:04:22
we all get excited by our own kids we always make the exceptions
00:04:26
and uh we have to really look at it you know it don't treat yourself to really than others right
00:04:32
and so the models of early special edition maybe this early intense training model
00:04:36
maybe like a lot of janice might do nick you made a lot
00:04:38
of hours in load early and the progress on and specialise early well
00:04:43
some made a layered for example in indoor into role big sports
00:04:47
uh and then in in that you might hours after you reach a certain level of maturity
00:04:53
um we didn't evidence based review about a five or six years ago we try to
00:04:59
include a um a number of uh um studies that were
00:05:03
we can you know a lot of case control studies
00:05:06
they demonstrated that most sports um specialist at the age of twelve only gymnastic specialist before the age
00:05:12
of twelve we have to improve the studies in it to do them prospectively as well
00:05:16
uh i need to look published a lot on a limb big athletes in
00:05:19
so no differences beeped i'm sorry saw that the olympic medal less
00:05:24
tended to specialise later and accumulate hours later which confirmed his
00:05:28
earlier work as well to in about sixteen hundred athletes
00:05:32
and so there's a performance potential benefit uh by delaying special edition
00:05:37
big goal for many ah american pages to get a college
00:05:40
scholarship and three on public studies including one of ours
00:05:44
demonstrated maybe ah um special vision didn't influence the
00:05:48
chance of a getting a college um participation
00:05:52
probably better study uh looking at about twelve thousand at least surveyed
00:05:56
demonstrate the majority of college athletes specialist before the age of twelve
00:06:01
which then leads to a lot of kids think hey
00:06:04
maybe that is the pattern there's certain corporates tennis gymnastics basketball
00:06:08
soccer ice hockey with the main culprits in that group
00:06:12
uh another study with about three thousand athletes compared high
00:06:16
school college and professional athletes special station rates
00:06:19
and saw that you know a two thirds of project is again special lies about half of high school
00:06:25
and professional athletes specialist so it's happening a lot of people are doing and are still having success
00:06:31
and the athletes their professional did not want their kids especially so
00:06:35
maybe the experience with them but they won for their kids
00:06:39
well i lead a um study with the w. t. a. professional tennis i'm allowed to share this
00:06:44
one slide that shows early specialise is versus late specialise there's at the age of ten
00:06:50
and that did not influence your ranking and so in
00:06:54
general there's to pass you can be successfully
00:06:57
oh you can be successful at a specialist under ten or
00:07:01
even having a late specials ration for professional tennis
00:07:05
we had um we looked at young about five hundred junior tennis players and found that
00:07:11
special station occurred at a very high rates um but the mean age was about
00:07:16
again ten years old so even for junior tennis players the same as professional so
00:07:22
um the maybe there is something they would really special edition in tennis
00:07:26
uh those we have a current group about hundred fifty out with
00:07:29
of tennis players and and see that the range tennis players
00:07:33
specialised earlier and play their first herman earlier the neon rain happily and we
00:07:38
have other data shows they they may get injured more but they're
00:07:41
getting ranked more so getting fat as when you're looking for me at
00:07:45
the perspective in maybe getting the participation um level to the wind
00:07:50
and and be a study best was very big in in the states in um uh we you know uh
00:07:55
when my colleagues you know found a lot of benefits for multi sport athletes in the n. b. a.
00:08:00
but only a but only thirteen percent more multi sport still
00:08:03
by far majority more were specialists even in high school
00:08:07
uh despite the fact that they would have fewer injuries and maybe have a better n. b. a. career
00:08:12
so we we know that either pat you can get actually
00:08:16
x. x. point a result with or without special station
00:08:20
uh and so the decision really is more on whether you want performance for participatory
00:08:25
model you want more get involved or do you wanna poke them really pathway
00:08:30
um many ask when should you specialise this is based on expert opinion only until we get
00:08:35
together more data but we suggested early entry sports would be like gymnastics swimming diving
00:08:41
um middle adolescence isn't many other sports many team sports
00:08:45
in late adolescence would be those that are running in torrance type sports um um
00:08:51
that could actually give you a better chance uh as you get older
00:08:55
so uh does this special station issue lead injury risk method reason
00:09:00
why people seem to want me to talk about it
00:09:02
will share some of those data but what's interesting is in this is the
00:09:06
end of two dozen sixteen i had been on and off or on
00:09:10
six different position statements regarding this issue of sports special station
00:09:15
and a systematic review at the end of two dozen sixteen rebuild only three articles
00:09:20
they had demonstrated association binge or risk six position stands
00:09:24
for three articles that number is gonna double and
00:09:27
triple by the end of even probably by this year uh is this the come harder topic
00:09:32
um we may have been the first to report this issue in a large clinical case
00:09:37
control trial uh published a couple of years ago and supported by or academy
00:09:42
um and we define sports special station has three components
00:09:47
year round training more than a eight months choosing means board including all other sports to focus on one
00:09:53
and if you did all three of these things you were considered highly specialised
00:09:59
and we found almost a equal distribution between highly moderate and low special station in this group
00:10:06
what was most interesting was there's a dose dependent um
00:10:10
a a fact where you are more likely get
00:10:12
over use in series obese injuries more specialised you work
00:10:16
however the opposite happened with the cute injuries
00:10:20
so you are less likely to get a injury related chewed issues
00:10:24
if you specialise more so this isn't over use issue specifically
00:10:31
so in summary we had these over use in in serious abuse injury associations
00:10:36
but we also develop an inductor car no uh whenever somebody's yesterday
00:10:40
so um what we think are general recommendations for young athletes which is if you participate more hours per
00:10:46
week then your age if you were sixteen we should do less than sixteen hours a week
00:10:51
uh for bores you could probably do fifty or fifty five hours a week safely not get her right
00:10:56
uh and then uh uh for a sports training ratio of less into the one of organised sports
00:11:02
tape free play and then are those that protects the morning eight months a
00:11:07
year nurse pour more likely to get all the user series obese injuries
00:11:12
um okay agree but wisconsin is done several follow up
00:11:15
studies have now been publishing found similar injurious
00:11:19
and also similar relationship to the degree of special edition
00:11:22
so how tightly specialised and highly specialised you work
00:11:26
i'm particularly again when we look at the
00:11:29
overuse injury risk increasing uh directly relate
00:11:34
to the degree of special edition versus the cute uh interesting the same
00:11:40
we look at socioeconomic status access to sport is an issue but
00:11:44
then also what you do with the hours per week in
00:11:47
uh we were a really um stand actually to see some of the findings relate to socioeconomic status where
00:11:54
those athletes to come from higher socioeconomic sets with more money
00:11:58
had a higher rate of special station and more series over use injuries
00:12:04
in in this happen pretty much related to insurance type as well too
00:12:08
so we label this study mo money mo problems um so we think that
00:12:13
there actually is a detriment due to some of your sports participation 'cause
00:12:17
it's more organised and it's protected we think potentially when you're in more
00:12:21
free place so if you just have it on to provide settings
00:12:26
we want to look at a um type of sport in relationship to sports
00:12:30
special edition this was this was just recently um published earlier this year
00:12:35
uh and again or a summer begets corporate so highly specialised sportswear
00:12:40
technical an individual and tennis and dance and gymnastics being those
00:12:45
and the type of injury tended to be again uh team sports which
00:12:51
are um usually more like football and soccer or football here
00:12:55
uh we're more likely acute injuries well individual sports are more
00:13:00
likely to have the over use in serious overuse injuries
00:13:05
well what others that type could be a risk without the the
00:13:08
adolescent female which we uh published earlier this year as well
00:13:12
and uh we relied actually since more females are
00:13:16
involved in tactical sports and dance and gymnastics
00:13:20
um they seem to be the bigger driver for some is overused answers to be used injury
00:13:25
which corresponds to other data about the risk of a adolescent oh overuse injuries and females
00:13:32
and so these are the type of high risk capital well along with a high risk athlete is uh in the end
00:13:39
we have done to your file out of this data now and when the more concerning things is we have four
00:13:46
a forty percent of our um our athletes over the
00:13:50
two year follow period resulted in other injury
00:13:53
and all those injuries the majority of them are are we carter or repeat injury
00:13:59
and so two thirds of these injuries now are that uh another type uh injury rather than only
00:14:05
a third of them being new injuries so it's the same repeat offenders better coming in
00:14:11
with our our longitudinal data confirms a lot of or baseline findings of the end of
00:14:17
our special ration read this in and they're uh training ratios in h. versus ours
00:14:23
but again we're seeing that um this we injury risk is an issue and we think will be the first report that
00:14:29
maybe there's an age association that's still weak but we're thing in cross actual data maybe less than twelve years old
00:14:34
you're more rest uh it the especially the young age less than twelve years old
00:14:39
i'm in survival analysis we did see that they're more than
00:14:43
three times likely for reentry of the highly specialised so
00:14:47
it's again those highly specialised elite level athletes that tend to
00:14:50
coming back and coming back for similar returned injuries
00:14:56
um but it's not all bad news and that's a message it's been recurring is that
00:14:59
it is healthy to play in sport we've done a couple of parent child studies
00:15:04
looking at um whether or not the kids impairs me access guy like even if they
00:15:08
specialise in both parent and child have healthy um um patterns of behaviour with exercise
00:15:15
a recent qualitative study were somebody for publication uh look at uh patterns that that the parents might
00:15:21
stages and most parents are a little concerned about activation but their kids still do it
00:15:27
and they still rape their health care locally live relatively high in that setting
00:15:32
so isn't the worst in the world there's still exercising their still meeting a lot of the things we want
00:15:36
and we do not have data suggested longterm health consequences yet and
00:15:41
we need long longitudinal accords to build a look at that
00:15:45
um we think maybe encouraging added earlier level uh this parent child
00:15:50
interaction could be uh could be a positive thing in
00:15:53
in in our study in our work we saw that parents of multi sport athletes played with their kids
00:15:59
alright size with them four times more likely to do that rather than um those specialised good
00:16:04
so my question to me encourage more parent trial has of interactions earlier on
00:16:09
um as you you may have heard the reason beaches simplify cast
00:16:13
about some of the critique of even even our data um
00:16:17
and so they ask questions like is this data acceptable is doubly having the right control
00:16:22
group and yes we have a lot of work to do to decide that and
00:16:25
is this risk of sports causation worse than the risk of the general population you know
00:16:31
yeah but uh talk was fan for normal to show us that maybe it is better to exercise
00:16:35
and then reduces injury rate and and not exercising is better health consequences
00:16:40
um so are summaries still level see evidence for many of
00:16:44
these risks including burnout and and potentially crappy skill development
00:16:48
um we are uh you know developing some injury risk association probably level be evidence
00:16:54
a project with serious obvious injury as well but still unclear about
00:16:58
the long term health benefit or um races specials asian again
00:17:03
at least they're exercising and they may more likely uh be physically active later in life
00:17:09
um so if we're to summarise what a high risk actually would
00:17:12
look like you'd be in the library all female younger
00:17:16
a tennis player for example specialise under ten do
00:17:20
we more hours per week dinner age and not have any free play have rich
00:17:23
parents and then um you know participate in train more than eight months here
00:17:28
and then um you could get you supplied in your office uh to take a look at her up for an injury
00:17:34
so uh you have to pass early purses late special ovation and there's a risk
00:17:39
your pat with early special station versus uh i'm late specials nation most likely
00:17:46
uh but we're not sure which pap is better for actually development and i think
00:17:49
that's the import messages the athletes will listen to the second part of it
00:17:53
what to develop edited and we can educate which is the which the better at regardless of which is safer
00:18:00
um
00:18:02
and so i do have a number of uh the ten commandments of overuse injuries for you
00:18:06
sports and and i i'll stay here you can uh take a quick picture that
00:18:09
you like uh and i think we had some of those review just with better carnal
00:18:13
again either general you sports recommendations not for that one percent elite level athlete
00:18:17
and so we're trying to uh at least give the speed limit for
00:18:20
some parents uh and coaches in in medical providers as well
00:18:26
see most the cameras done this more cameras in my wedding this is great
00:18:32
um and i don't know if we had a volume here for this one but you know uh over the needy if we have volume but uh
00:18:39
this is my sign in in trying to enjoy sports and remember
00:18:43
sports or for fine that's but they were invented for
00:18:46
we have a change things quite a bit in in my kid he usually it's about wanting things and celebrate
00:18:52
from for nazi as uh ninety one uh ask celebration
00:18:56
the playing ratio which is very safe or interest
00:19:00
and so uh we have to keep reminding ourselves that's what sports are for we're here for fine okay
00:19:05
uh i mean i think all of the on i think my family my wife uh actually
00:19:08
stop by for the first time i see things you may ever seen the speak
00:19:12
um and uh this is please again remember this the beginning of what we're doing with you sports here
00:19:17
uh and boris and and the rest of you i think we have to keep helping them uh
00:19:22
work on this over the next uh several in many years thank you so much ha
