shortly knowledge mores and phonetic respectively chairman president
00:00:06
of conference i'm delighted to be here
00:00:09
and i'm assuming that all that was and also for professor hogan leaner
00:00:14
i was one of these former t. d. student and might
00:00:18
talk is titled biological development on both ways to success
00:00:24
first of all that is make a consensus on central topics to understand my cock
00:00:32
don't we first to change in body size it is probably
00:00:35
be mine biological activity during before spec itself life
00:00:39
and it has implications on tiles proportionality shape and body composition
00:00:47
maybe talk about the first two decades of life it is also important to note
00:00:53
different the usage and different organs
00:00:58
present distinct group curse of who would seem you are shape and
00:01:05
form but grow good for boys and girls are distinct
00:01:10
usually females tent with pain had to state before boys and i believe this
00:01:17
is a huge implication in the organisation of long term support carrier
00:01:24
what is also unique during the first two decades of life use
00:01:27
but lessons you specific from almost hawkins we know that from
00:01:33
evolutionary timely and sports what is all about salsa loading sport is uh
00:01:40
wonderful opportunity to force also learning interaction with peers
00:01:47
movement from family to peer relationships the supervision of adults and in many
00:01:53
cases coaches are among the most to prevent adults for children's
00:02:00
and when we talk about sport more exactly organise it in kentucky sport
00:02:06
we training and competitions and under the supervision of adults mainly coaches
00:02:14
it is probably my opinion the main form of physical the t. v.
00:02:18
t. green bay is the study came from canada peter cut twenty
00:02:24
collected the data in cafe on it was clearly demonstrated that
00:02:30
sports organise it sport is a very substantive form of physical activity and this
00:02:37
is clearly if you don't among the moderate to vigorous intensity level
00:02:43
which is believe it to have a benefit effect on cardiovascular hell among other benefits
00:02:52
inside this week the consistency when this same conclusion is that painted
00:02:59
with different studies and this was the case in portugal
00:03:03
we collected data also under the supervision of professor hogan melinda
00:03:08
and clearly again sports is probably the main form of physical
00:03:12
activity is a very relevant to even for public health
00:03:17
but when we discuss children ended lessons
00:03:23
we may need to figure out variability and many studies put all
00:03:29
the focus on mean and central tendency panthers in statistics
00:03:35
so
00:03:37
variability is all about biological but to ration it is not underlined process and
00:03:44
s. to underline cause that's when it's temple that is right right
00:03:50
we usually obtain eat from the classification of scalpel h.
00:03:56
contrasting with chronological age and each individual is classified
00:04:00
as the late on time what advances
00:04:05
which is very different from timing the other underlying concept
00:04:10
when we talk about timing we are simply
00:04:14
talking about a specific appearance age at anarchy eight a. p. chi velocity
00:04:22
and the slide was publishing two thousand actual sports science special issue
00:04:29
that wasn't denies it and edited by thomas huh i highly
00:04:33
from people people don't move the diversity and it refers to portuguese
00:04:38
that uh i mean values of that lesson soccer players
00:04:43
plot to eat on percentage fifty percent for stage and
00:04:48
body mass against united states have fairness data
00:04:54
and this was consistent from the age of eleven through fourteen years
00:05:01
after that specific h. fourteen years maybe values
00:05:08
especially for both the boss didn't to plot on the percent down
00:05:14
seventy five percent in other words during late adolescent years
00:05:21
soccer players aged fifteen sixteen the tend to carry more body mass
00:05:26
for stage or why but this is cross sectional data
00:05:32
wherever sent to use can from send steady and the authors
00:05:38
in this it will be classified according to scale to lay each each
00:05:43
individual soccer player is the late on time or the tacit
00:05:49
in red are infant tiles aged eleven twelve
00:05:53
almost the same percentage classified is delayed or advance eat
00:06:00
around fourteen years of age it looks like that soccer players tend to be advance it
00:06:08
and he gardening the green box players aged fifteen sixteen years the ones who are
00:06:17
classified as they laid out as it will no more than two percent
00:06:22
so i'll again is this consistently consistent we deleted
00:06:27
two two books yes cassie audi in italy
00:06:31
i painted the same findings in a in a in a manuscript that was published in european java byte fidelity
00:06:38
use it up you don't there's to assess the stickler volume and
00:06:43
until the age of fourteen a control group and at last and soccer players
00:06:48
presented almost the same size of the test testicle involving afterwards clearly
00:06:57
soccer players presented larger volumes done control groups
00:07:05
what is all about the age of fourteen according to the girls' books
00:07:11
it overlaps with maximal growth in stages and
00:07:18
cannot philippe uh it's from famished portion of belgium
00:07:23
it published a paper enjoy sports size two thousand six and concluded that a. j. p.
00:07:28
chi velocity minus six months to a jet because i was thirty plus six pounds
00:07:35
well what email window for trained ability in most of the items
00:07:40
from the motor performance battery it is very real event
00:07:46
so i'll we need also to look about availability on in that particular we assess it
00:07:56
at less than coaches basketball players all at the same age on that fifteen
00:08:02
classified according to stage of we care development
00:08:06
stage three stage four and stage five
00:08:10
and wanting stage five would paul l. seventeen centimetres yeah if you're more than thirty kilograms
00:08:18
and they think better performances in those tasks
00:08:22
that remote required body displacement however
00:08:28
for the pain tomato shuttles and
00:08:31
the test proposing but not lazy in nineteen eighty eight
00:08:36
doubles players wearing stage five a tape would performance
00:08:42
this is well illustrated in these pictures in these graphics
00:08:46
and we know also all
00:08:50
from my mosquitoes in two thousand twelve was the most sighted manners we enjoy all sports science
00:08:57
biological motivation is the underlying process that has many indicators they are not supposed to eat
00:09:04
to correspond perfectly to each other or wherever also from the journal of we retain the following
00:09:15
centrally mediated people would he is given by to stick out of all the main points
00:09:21
why do we care development is uniquely a sign of the onset of other knock
00:09:29
for taking into account these limitations repeated the same research question
00:09:36
what is the variability around the age of fourteen that was considered critical
00:09:42
and the conclusions it up this time came from soccer players were classified according
00:09:48
to scalpel h. d. late on time advancing not anymore we care
00:09:54
and those soccer players in that i barely at that early
00:09:59
or advanced age group i work again taller heavier
00:10:06
and a tank would performance in aerobic fitness something's wrong with aerobic fitness
00:10:11
it contrasts with other handguns from up the performance better and not
00:10:17
get skills i'm not related which got on the duration
00:10:22
looks like again it is well illustrated in these graphics
00:10:28
so i'll let us put all this knowledge and information it to a practical application
00:10:34
how what is the contribution to explain sport selection
00:10:38
and we did that in a sample of more than one under each porches soccer players
00:10:45
that were classified as local players or rational players reginald players
00:10:51
were those selected to take part of representative districts
00:10:57
from a value in cleaner which are most relevant in portugal besides with an import to
00:11:04
and spot selection using function of the screen internal disease
00:11:08
was explain it by stage an edwardian patient
00:11:12
speed agility jumping performance was in addition to use of training
00:11:18
in other words sex a. s. at this age is a combination of biology
00:11:23
during the beauty and probably culpability the quality the quality of
00:11:28
coaching definition this is well illustrated in these graphics
00:11:34
age of fourteen we face a substantial into individual variability
00:11:42
however we did not assess any laboratory protocol on these was don a mole
00:11:48
at lesson hello good place which i believe is by putting a clue
00:11:53
more than seventy if part two participants will aged between fourteen and sixteen years
00:12:01
few ones was selected for the porches national team that
00:12:04
was first place eat in group internment real elite
00:12:09
on that spot selection was explain meet again using
00:12:14
function discriminant analysis by hand reached right
00:12:19
functional race you from eyes of kinetic tenement that
00:12:25
playing time and training time plus the thirty second mean gate test which
00:12:33
makes total sense sense it is a whole pile maximum effort
00:12:39
the article was also sets it in a training up but did not enter in the equation
00:12:46
oh and one calling from conning i'm not i i think the answer you classify it
00:12:52
participants in soccer as those what pain have professional level windows what pain
00:12:58
on the amateur level and data was was you to the movie
00:13:03
on the best display mean and into longitudinal profiles word speed agility and camping
00:13:10
and those free tests were the dependent variable of another paper
00:13:15
this time closer to the end of applied physiology by professor herbert melinda
00:13:21
and for each dependent variable using multiple so that action analysis
00:13:26
it was possible to find to put the page cross sectional data
00:13:33
natalie can training body mass on the two d. stage and the tele
00:13:38
t. so the question is how those factors of i think
00:13:42
are they additive factors what mathematically they interact and
00:13:47
our multiplicative fact when it to aunt
00:13:53
to try to find in the library research retrospective data to studies
00:14:02
where obtaining one from portugal another one from said yeah
00:14:07
the one from portugal assess it's got the wage losing
00:14:09
the not american mapped out fell and those players
00:14:15
get what assess it at thirteen fourteen years and that they need the best portuguese professional perhaps
00:14:22
were different from the others those to continue in local but and also drop out
00:14:29
and it it isn't the best ones with these didn't in size
00:14:36
or performance tests not phone bills that do not require body displacement
00:14:42
um it's done of l. t. e. sports seat excuse
00:14:47
what do discriminant high times between those groups
00:14:54
hot jabber study from said yeah get use it's got the light
00:14:58
also this time we depend on right of probable loop in
00:15:03
and the outdoors concluded that doubles players who i teach in the
00:15:08
sandia national team hundred fifteen i would more likely to obtain
00:15:13
let me get painted we call still bongos league and french confessed only doles one
00:15:20
we're looking at you worth which is in contrast with cross sectional data cross
00:15:25
sectional data suggest that sports retain jet that players specify this address it
00:15:31
hi perspective data suggest that the one that you will get was it well in the paper of
00:15:37
two thousand journal sports i guess we're now probably the ones within success in in professional weeks
00:15:46
so i i briefly told that two protocols and available to assesses couple age
00:15:55
one is from not american fells how lex harsh was the first thought that
00:15:59
while the other one was proposed by the group lead by james william penn
00:16:05
the two particles are basically in the same assumptions that request
00:16:09
a few x. ray from left and then released
00:16:16
and this paper emerging two thousand seven that annals of in biology
00:16:21
the only only the data from the l. monday the second all those are the
00:16:25
physicians from comedy and it looks like the same subjects assess it to protocols
00:16:32
american will be in the european protocol panel mike tells underestimates couple h. he's might have
00:16:40
impact on the classification we need to continue to study do topical related variability
00:16:49
and very briefly probably the difference if you read it carefully to lead to two groups door you know books
00:16:57
for the l. p. in proper call addled state is that they need a th of sixteen point five
00:17:05
while for the fells map out the north american one minute you were
00:17:09
an adult state is a trainee at age of eighteen for males
00:17:14
which may be the difference so we have no i see the data and we can
00:17:18
back to the book to the library to discuss and we found that specific aspect
00:17:24
so let us take a look on interactive it'll projector is
00:17:28
the process is not always a line maybe that could really in years
00:17:33
which is totally different and statistics reuse it repeated measurements
00:17:39
and rational analysis which is called it multi level modelling
00:17:45
and base it on
00:17:48
repeated spins noted by nite them set s. critical to
00:17:52
discriminate players that painting professional and amateur level
00:17:58
looks like that scalp college did not into it as opposed to the appropriate of something that is
00:18:04
that if a given to smoke it and yeah put it does whatever we can do this
00:18:11
train the d. v. d. lowell in strength
00:18:16
and simply we're facing the complex interrelationship of that the slide cans from don't
00:18:24
reassessing more than two thousand time measurements on two items from
00:18:31
all pocket dimension but pretty name e. t. t. v.
00:18:36
moving sideways injecting sideways what allows you to do not predictors of chopping performance the outcome
00:18:43
compare movements and spending bill jam i want you to do not like
00:18:47
the uh this was also true for you you intermittent level one
00:18:54
one item from up across the nation and that in as opposed to the top predictor final message
00:19:02
a paradox between cross sectional data and had perspective data
00:19:08
we noted before
00:19:11
that also scalpel motivation is independent of soccer skills
00:19:19
which may be very useful for talented indication do not too
00:19:23
too focused on something that is confounded by biological maturation
00:19:30
and we made an cues about why this happened
00:19:34
it does it play as a tape would performances
00:19:38
to lose one can from the girls who who contraction is well illustrated coup contraction
00:19:45
is more often fine found among players what early i understand that philly pets
00:19:53
assess it qualitative data on the hunted economy strikes trying
00:19:57
to express it as a percentage of eggplant
00:20:00
really the two worst compressed agreed like let you where's the remote
00:20:04
tools were less effective so we have good clues to understand
00:20:11
um here i call on our genetic automatic scanning
00:20:16
before cool t. c. input all the years and late
00:20:21
adolescent years he ought to be directly assess it
00:20:26
was intended evolve variability explain it by different size descriptors lean body mass
00:20:33
hi janelle obtained a plot little would lean mass assess it died will x. ray energy absorbed geometry
00:20:40
and later on body mass no fat beats around here
00:20:45
so my my last and final call use we need to face to warm them preparation
00:20:52
s. something that is not clean yeah it's probably a fact along the phenomena
00:20:58
and i'm glad to be part of a large network of researchers
00:21:03
today i was the speaker but most of these will come from probably it's bar is fine thank you one minute sorry about that
00:21:13
hi
