uh_huh
00:00:03
yeah yeah i think i'll start out with the question and we all know the
00:00:08
yeah i help anything it's all youth sports but at an elite level
00:00:13
are these health benefits actually outweigh that by the uh injury risk
00:00:19
and uh in short maybe the answer is yes based on
00:00:24
what we've just learned also from a really bad
00:00:27
but uh i'll uh try to illustrate this today and
00:00:30
i'm new mainly through my take on messages
00:00:35
that is um you we've seen that the prevalence of
00:00:38
health problems is high ammonia and use elite athletes
00:00:43
we know that um sport category matters we know that insurance um athletes
00:00:50
have more illnesses and i'll come back to date on the if
00:00:53
but one in for my to puerto male does at any given time and
00:00:58
um we see that technique on team sports athletes report more injuries
00:01:03
maybe as many as one in three at any given time and finally uh we also see that across
00:01:09
the different sport uh uh categories and you're exactly it's
00:01:12
a technical that lead themes but that late
00:01:16
we know also that the prevalence of a or b. is injuries
00:01:20
is high and quite equally distributed across the different sports
00:01:25
and then for your information most of the data that i'll be presenting today is
00:01:29
based on a prospect is that is that we just created in norway
00:01:33
on youth delete 'em athletes now first i'll
00:01:37
start out with a presenting yeah mm
00:01:40
mikey who are actually right in the middle of
00:01:43
the challenges related to um utility the sports
00:01:48
uh this is their christopher you is the eighteen years of age you know to ski as
00:01:52
you can tell and i guess a lot uh the mountains around here as well
00:01:57
and he's a twin tips here and a couple of years ago he was
00:02:00
an admitted to have what academy high school in uh in norway
00:02:05
uh unfortunately after uh use first here he erupted he's a. c. l.
00:02:10
which as we have learned now it's quite a a a a serious injury
00:02:15
unfortunately yes trained well and now it's uh uh back in business
00:02:21
and then we have uh am earlier with the french is say
00:02:24
sixteen years old she's the high level team um handball player
00:02:30
and um these sex balls uh sorry to uh participate in multiple
00:02:35
teams of local teams or regional and national representative teams
00:02:40
and she's been picked out to um specialist town programs
00:02:45
so she ends up with a quite a high training and competition node and does this
00:02:51
expose search to an increase the risk of injury is we don't know fortunately
00:02:58
uh we also have really pushes twelve years old and she
00:03:02
is still enjoys multiple sports soccer team handball alpine skiing
00:03:07
and uh fortunately she is still an specialist even though she's a twelve years old
00:03:14
and we know now from previous studies that twelve here is kind of a a breaking point
00:03:20
yeah yeah of whether they uh the kids start to
00:03:24
crack this single sport or specialise in their sport
00:03:29
so i'll
00:03:31
we know that you delete athletes might be exposed to fear if
00:03:35
injuries high training load of early specialise h. m. and
00:03:42
we see that there is a trend towards more training more specialised training
00:03:47
at an early selection um into town programs
00:03:53
despite the concerns of a medic medical compute uh communities and maybe this
00:03:58
uh concerns of all of us uh it being your today
00:04:06
contributing factors that might could be yeah most talented
00:04:09
athletes at a greater risk of injury illness
00:04:12
is also when they start and the and the senior high school
00:04:18
they have a transitions from a club based program to more specialised
00:04:22
some of them and specialised for to get my high school
00:04:26
and these smart all's a a lot of times a lead to pass steep increase in training load
00:04:32
for many of them before they started a specialised high school the train might maybe three or
00:04:37
four times a week and then they start on the schools and training twice daily
00:04:44
uh also we see that the most gifted uh athletes are is selected for both regional
00:04:51
and national representative teams like uh our door to or a into special time programs
00:04:57
and this might also a result in participation on multiple
00:05:01
teams with an increased uh training and competition load
00:05:08
now here are so mad prospective studies that i think are quite interesting
00:05:13
regarding use if indeed the tennis players or interiors and alpine skier is
00:05:19
the uh one for the most to the left is
00:05:22
a dutch tennis study committed by a blooming coworkers
00:05:26
on seventy elite junior tennis players between the age of eleven and fourteen
00:05:33
and therefore them for thirty two weeks and reported i
00:05:38
prevalence of health problems of twenty one percent
00:05:41
and at an ever uh any given time twelve percent uh reported and always injury
00:05:49
now yeah the middle study here is uh from sweden
00:05:52
from phone roles not all looking to sixty elites
00:05:57
or the interior is they were a bit uh older between sixteen an eight a. eighteen years of age
00:06:03
and and they were uh into a specialist sport academy high school
00:06:09
and they reported that uh the problems all uh
00:06:13
into his overall or thirty eight percent and
00:06:17
one in three reported a yeah overuse injury at any given time
00:06:23
and out to the last study here by email or at all which
00:06:27
s. o. will be presenting later today i'm looking forward to that
00:06:31
and eighty elite outlines year is a bit younger than the
00:06:35
as we do study between nine and fourteen yeah
00:06:38
so uh yeah yes of age and therefore them for two years with which is quite good i think
00:06:43
and they're they're reported and i enjoy incidence or his uh injuries over the zero
00:06:49
point three um injuries separate thousand training hours in acute injuries was higher
00:06:55
of course this was alpine skiing acute injuries of the zero point eight heard about a thousand training
00:07:01
i with now in no way and uh this is part of my p. h. d. projects
00:07:08
we recently committed a perspective cord study evaluating the um
00:07:12
magnitude of health problems among use elite athletes attending specialise
00:07:18
sporty cat in our schools and we've looked into the prevalence and severity of injuries
00:07:22
and illnesses across a variety of a a sports for a twenty six weeks
00:07:30
the participants of our study were a sixteen year old
00:07:34
voicing girls from mad three different sport academy
00:07:38
high schools and we also had a small group
00:07:41
of their teammates attending regular high schools
00:07:46
they're into team sports that and so in the court there are
00:07:50
thirty different sports and we've divided them into three different categories
00:07:55
technical sports in during sports and that team sports
00:08:00
uh we also evaluated their sports history read does retrospective really uh
00:08:06
at baseline which i'll walk you through in a minute
00:08:08
and we collected the there um perspective injury and illness data weekly
00:08:13
true annually developed smart phone application using the uh also for trauma research
00:08:19
centre questionnaire on health problems which you might be familiar with
00:08:25
now just to walk you through would be yeah retrospective sports history data regarding
00:08:31
yeah they're primaries port to view a just that's illustration whether there
00:08:36
were into single or multi sport at the age of fourteen
00:08:40
their average weekly training load uh when fifteen years old
00:08:45
and uh uh their self reported performance level
00:08:51
to start on with their sport debut most of them started playing the sport at an early age
00:08:58
eight years or younger and then maybe not a surprise
00:09:02
the t. v. sport athletes started in the sport at the
00:09:05
uh their earliest and significantly earlier compared to insurance
00:09:09
in technical support and this was two in particular for the um soccer players and the eye socket place
00:09:17
did they would you that a growing number of coaches and parents believe that the best way to
00:09:22
produce superior young elite athletes is to have them play only one sport from young age
00:09:29
uh um and this uh of course is what we call early specialist station and looking into this
00:09:36
we defined early specialist station as says specialised thing
00:09:40
in us board at twelve years or younger
00:09:43
and we saw that this was most common forty men technical that late
00:09:48
approximately fifty percent of the team and technical athletes in our group i
00:09:53
decided to specialise in the sport at twelve it euro younger
00:09:57
and only at approximately one fourth of the insurance um
00:10:03
athletes had specialist at all twelve audio or younger
00:10:07
uh looking into uh whether they were doing apparatus thing
00:10:10
at once for only one sport or multiple sport
00:10:13
here is well we can see that more than fifty percent of
00:10:16
the team and technical the athletes practised single sport at fourteen
00:10:21
yeah for team sport it was actually a bit higher and they're worth the enduring
00:10:26
zap plates here as well one in four practised single sport at fourteen
00:10:34
the prayer performance level you know code was quite high thirty seven percent of
00:10:39
the elite sport athletes i participated at the um junior senior national teams
00:10:46
and approximately a hot for the young like that is a
00:10:49
rated their performance level as top five percent nationally
00:10:55
now there are fairly new recommendations regarding weekly training ought not to
00:10:59
exceed the ah eh athletes on h. i. now caught
00:11:04
we saw that one in four exceeded this age what in four reported a weekly training old
00:11:10
i completely snowed of more than sixteen hours per week when they're they were fifteen years old
00:11:17
and about fifty percent of them trained between eleven and fifty now
00:11:22
it's weekly when fifteen years old is was across all sports
00:11:26
now i'll go further on the with discussing at the prospective results regarding
00:11:31
at the magnitude of health problems in a um i manipulate objects
00:11:39
here we can see a graph of uh all health problems
00:11:43
uh reported across all sports through twenty six weeks
00:11:48
and uh all the health problems are uh in the blue bar is
00:11:53
a substantially elbow problems are in the green bars about substantial
00:11:58
health problem i mean that they're a performance or the
00:12:01
threat training volume is supported by the athlete to be
00:12:05
to be reduced at a moderate way or more
00:12:10
on the y. axes uh you can see the average weekly prevalence
00:12:14
of a health problems uh um reported by the athletes
00:12:21
during the twenty six weeks we saw a with a nine hundred
00:12:25
and swell uh i have complaints that were reported and
00:12:31
every single week forty three percent of the youth elite athletes reported i have problem
00:12:38
and warnings for reported a substantial how problem meaning
00:12:43
as i said that their training volume
00:12:46
or their um performance was a performance was affected in a modest way worse
00:12:52
now this forty three percent how much cause that you did add
00:12:57
the injuries and how a great to poison work the illnesses
00:13:02
we see that of the forty percent it's a hell complains in total injuries uh was
00:13:09
reported at any given time by thirty one percent of the elite athletes and illnesses
00:13:14
twelve percent or a at any given a at any given time
00:13:21
so i'll and the injuries
00:13:24
how was the the distribution between acute and overuse injuries
00:13:29
it was actually quite a evenly distribute it at at any given time
00:13:35
seventeen percent all the you've really got into puerto than overuse injury and fourteen percent
00:13:40
uh reported in acute injury and of course this a difference is not significant
00:13:46
we also saw that between gender girls reported more have complains compared to boys at any given
00:13:51
time more than hall for the young elite athletes girls reported i haven't i have complaint
00:13:58
uh compared to about forty percent of the boys
00:14:02
uh this different the is also um and visible on the um
00:14:08
substantial injuries but um the difference between these two bars is not significant
00:14:16
so how do sports category influence on the athletes health complaints
00:14:25
we saw that for it you exactly it's cross country skiing for instance or by a lot at any given
00:14:31
to our swimming at any given time one in four
00:14:35
twenty three percent reported an illness of any kind
00:14:39
which is of course that much more and significantly more compared to technical into sport athletes reporting about
00:14:45
ten a ten percent at any given time and um but
00:14:53
in contrast one in three of the technical and team
00:14:57
sport athletes reported and injury at any given time
00:15:02
which was significantly more uh then during during satellites now for the looking into the um
00:15:09
distribution between acute an obvious interest between the different sport categories
00:15:14
as i said approximately fourteen percent reported an acute injury
00:15:20
every week across all sports but this was mainly from the team
00:15:24
and technical support athletes this was we're going acute injuries
00:15:32
uh for all use injuries the picture is different um
00:15:42
all over the call while we saw that and that uh as i told you a seventeen percent reported
00:15:48
and all the use injury across all sport every week
00:15:53
and that when we break these down between the different the
00:15:56
sport categories and you're exactly it's technical that leads and
00:16:00
teens but out it will see that the numbers michael very
00:16:03
uh somewhat but this difference is that not um
00:16:08
significance so i think that it's safe to say that or
00:16:11
use injuries as a high prevalence across all sports
00:16:19
and finally as i told you uh in our call what we had both elite athletes
00:16:25
attending sports academy high schools and also sub elite athletes attending regular high schools
00:16:31
and we could also see that the elite sport academia athletes reported
00:16:35
significantly more substantial injuries twenty two percent at any given time
00:16:42
compared to their non sporty catnip years reporting a
00:16:46
problem so ten percent it's meaning that ten
00:16:49
percent of disability that it's reported a substantial injury at every get at any given time
00:16:58
and if this is related to hire training load to the elite athletes being more talented
00:17:05
or to them it being exposed to as several
00:17:08
different teams uh are are really only speculations
00:17:14
now
00:17:19
which of the three health problems affected the athletes the most
00:17:23
as you can see here illnesses represented the great majority of
00:17:27
problems forty nine percent this at any given time
00:17:31
and over use an acute injuries each represented about a quarter of
00:17:35
the health problems reported during the twenty six week period
00:17:40
and uh this differs somewhat from previous studies
00:17:43
using a timeless injury definition work acute
00:17:46
injuries had be in a often reported as the um major health problem
00:17:55
if we all soul take the severity of the health
00:18:00
problem how the athlete recognises the whole problem
00:18:05
to be for that for them and did you ration into accounts
00:18:10
with a even a different picture because even though illnesses is the
00:18:14
most was the most reported no problem in our study
00:18:18
uh it has a high severity when you're able bodied
00:18:22
last for quite a short period of time
00:18:25
words for only use injuries which has a lot with severity they participate yeah they
00:18:31
they participate in this sport even though uh um they haven't overuse injury
00:18:38
it eh so they're puerto lower severity but without
00:18:42
much longer duration and based on this
00:18:46
we uh had estimated the relative impact all the different
00:18:50
health problems on the use elite athletes health
00:18:54
and and from this we can see that the relative impacts were roughly split
00:18:59
into thirds between all the use injuries illnesses and acute injuries and
00:19:06
from this we could say that all these uh different three problems are equally important to the utility that it's
00:19:14
now to um some of my talk and go back to where i started
00:19:19
i think it's safe to say that the problems of health problems are high
00:19:25
i'm on you've really got it and it at any given time forty three
00:19:29
percent to report a a health problem of any kind and the
00:19:34
twenty five percent reported substantial health problems affecting
00:19:38
their uh performance or training volume
00:19:42
and we've also seen that sport category matters in during that plates report more illnesses
00:19:48
yeah at any given time one in four reported an illness various technical in team sports report more injuries
00:19:54
at any given time one in three reported an illness and a uh injury
00:19:59
and um according to our data or we use injuries is also
00:20:03
a major health problem in this uh group regardless of a sport catch
00:20:08
really really and i'll also say that we have seen that
00:20:12
the team and technical sport athletes tend to specialise early in the sport amtrak
00:20:17
this single sport a i'm much more than insurance that it's you
