hey what's up everyone morey croson and we have a very interesting topic here today we're gonna
be talking about nature versus nurture and we're gonna start the video right now
so this is something that i've been thinking a lot more about recently is i have this upcoming
100 meter race coming up and as i'm getting into the training and getting more into it you know
i've seen some people that have talked about how they've been able to cut off you know a second or
second a half or watching the olympic trials you know really gets into the thought of you know is
it possible for somebody like me to be able to run under 10 seconds especially because of how late
i got into sprinting so i've really been doing a lot more research and talking to more people
about it to see you know where is the scientific data to show the role that genetics plays when it
comes to top tier sprinting or really just elite athletes in general and since i'm training for
the hundred meter myself i did tailor much of my search results around 100 meters so that's going
to be where most of this information is going to come from but just to give you a quick background
before i get into some of the results that i found i am somebody that personally believes
that it has much more to do with the nurture side than the nature side of the genetic side so i
believe that being able to you know work hard and follow the right training program will create a
opportunity for your body to be able to adapt obviously genetics play a part where i don't
believe that i could run like nine five eight like you say in bolt or you know have a tremendous high
jump i do believe there are obviously some genetic limitations but when it comes to being able to
compete at a very high or elite level i do believe that we all have the opportunity to be able to do
that we just we have to be able to follow the right regimen and also i do believe that the
environment that we're in does have a huge role in the type of athlete that you can become long-term
so if you take somebody like usain bolt and take him out of jamaica where they invest a lot into
track and field there's a lot of competition with track and field and the 100 meter and
you know just the overall community base behind dragon field you know you're
a really well recognized individual if you're somebody that is the fastest person in the
area and things like that where you know you take that person and take them to maybe like a germany
or brazil or really any country where soccer is more invested into rather than track and field
and you're going to get a significant different result than what usample was able to achieve
by him growing up in jamaica again that's just my opinion and you know i do want to go into
some of the research based off of you know where i'm coming from because i didn't want to be able
to go into the other side of that argument right i realized that i have a certain degree of bias
going into the research here so i did want to go more on to where are some of the specifics
that can prove me wrong then i also want to go into some of the things that justify
where i'm coming from so first thing we'll go into some of the key things that show that
you know there are a lot that goes into the genetic side of it and the first thing i want
to go into is the actual 100 meter race and the world record holders behind the 100 meters race so
one of the key things that stands out is that since 1968 all of the world record holders in
the 100 meter dash have been from west african ascent or quote unquote black athletes which is
legitimately what it says here in the article and the other thing about that is since 1912 in
the entirety basically of the event since they've been keeping track there's only been 10 non-black
athletes that have been world record holders so out of the 38 individuals that have held the title
28 of them have been black i do want to say i hope i'm not offending anyone by saying black athletes
it does feel almost weird for me to say it like that but it's really the only way to be able to
describe it because there's so many different countries that people are from you know you
can't just say like african or african american you're like hey the only way to be able to really
describe it is by just the pureness of you know black white or whatever the color may be so you
know go back into the video hope i'm not offending anybody so in the research black athletes tend to
have longer limbs with smaller circumferences meaning that the center of gravity is a little
bit higher compared to like whites of the same height and while these differences may be small
the longer torsos that like asians and whites might have is gonna have an effect on the center
of gravity which will then lower down a little bit in comparison to again black athletes are
gonna have a little bit taller center of gravity and when it comes to the 100 meter race it's going
to have a big influence because the center of gravity impacts how fast the actual legs could
be moving so somebody with a lower center of gravity is just not going to be able to move
the legs as fast when the foot hits the ground because of the amount of balance that that is
going to be able to create or somebody that has a little bit higher center of gravity is going to
be able to create a little bit more speed into the ground when the foot is hitting which is obviously
going to make a big difference in something like a 10 second race or running 100 meters or you know
something like that so that gives you a little bit more understanding of the body type of a sprinter
somebody that needs to have a little bit shorter torso and a little bit longer legs and while there
are more black athletes that kind of fit the build there with having shorter torsos longer legs to
make it so they have a higher center of gravity there is a smaller population of white or asians
or hispanic people that also have longer legs and shorter torsos it's just not as prevalent as
with the the black community i'm going to quickly interrupt this video just to say if you like the
information so far go ahead and click that thumbs up down below that really helps us out a ton and
subscribe to the channel if you haven't already and we're gonna hop right back in the video
the next big thing is going to be a gene called actin a or act n3 which is a gene that directly
correlates to explosive power elite athletes top sprinting and is essential for any really
top sprinter to have within their body and what's interesting about this gene act and three is that
you have to have the right part of the gene for it to actually be the sprint version which is 577
r is the actual name of it and the thing about it that's interesting here is that this 577r that is
needed for top spread performances in 98 of jamaicans but is actually in 82 percent of
europeans so it is something that is essential to top sprint performance but it's also something
that a lot of us have within our body so it doesn't necessarily show that usain bolt or
michael johnson or esopha power any of these guys are genetically gifted because 98 of jamaicans
have the gene necessary to compete at a very very high level however the two percent of jamaicans or
18 of europeans who do not have the act 3 gene are basically out of the mix when it comes to
competing at a high level in sprinting so while this does show the importance of genetics when it
comes to a lead sprint performance it doesn't give a explanation for why when usain bolt lined up and
ran the 958 all the other track sprinters that were right there next to one who have very similar
gene expressions were not able to accomplish the same result so in my mind this just showed
the importance of training when it comes to top performance and speed and this is a great quote
that i thought was going to be really important being able to show that is that one of the most
beautiful things about the human body is its resilience and its ability to adapt to physical
demands like exercise training our bones muscles tendons heart and lungs will adapt to the stress
exposed to it right so just saying that based off of the physical demands that you put on your body
you will make the necessary adaptations to be able to meet those demands this is very important for
sprinters to be able to understand when it comes to training because a lot of people end up trying
to run longer distance or build up more endurance type muscle or more cardio or things like that
when it comes to sprint performance and that will have a negative effect on the actual muscle fibers
that get developed when it comes to sprinting performance we have to be focused on explosiveness
we have to be focused on more strength power things like that build a slower contracting muscle
so it's really important when it comes to muscle growth or having the adaptability necessary to
be able to sprint is being able to change how you work out to be able to meet the necessary demands
of sprinting like 100 meter dash for instance so like i said before you want to stay away from long
runs you want to stay away from more cardio type exercises you really want to keep everything much
more explosive and if necessary be able to train more often within a given day so it gives you more
of an opportunity to be able to rest and recover for your muscles to then be able to have a strong
output again where if you go for maybe like a 90 minute workout there's going to be a time where
you're going to go from the anaerobic muscles to more of the aerobic muscles which is going to have
a negative impact on what it is that you're trying to do as the aerobic muscles are going to be more
of a endurance type of a muscle that's going to be work where you want to be working more of the
anaerobic muscles which are more of the explosive muscles in order to do that you have to work at a
very high intensity now what happens when you go for let's say 90 minutes in a row the intensity
is gonna obviously go down over a period of time which is going to impact how you're working your
muscles but if you could let's say break up your workouts into three 30-minute sessions now you
could be a lot more explosive within that time period which will help in building your speed over
a long period of time really the key here when it comes to building speed over a long period of
time is that you don't plateau you don't get to a point where you're just at the ceiling of what it
is that you can actually accomplish so in order to do that you do want to change up how often you're
working out you want to change out the exercises that you're doing you want to change up the order
of the exercises that you're doing you want to make sure that you're getting adequate rest and
recovery you want to make sure that you're taking your care of your body from a meal perspective
and the last point that i just want to make is going to go into wolf's law and the reason this
is important while it kind of takes away from the the muscles and the genetics i do think it's
important because of the ability of adaptation that we actually have within our bodies and what
julius wolf actually found and this was in the 19th century is that your bones are actually able
to even recreate themselves so there's different types of osteoclasts which absorb old or damaged
bones and then there's also osteoblasts which deposit new bone tissue into where the old tissue
was and so this obviously happens over a long period of time but you actually have changes
that could happen to even your bone structures over your life period so if you can have changes
to something that is so dense and so strong like your bones and there's undoubtedly changes you
can make to your ligaments to your tendons to your muscles and so everything is able to adapt and it
has a lot to do with how you're training and while the research shows that the genetics does play a
part in your actual sprint performance it doesn't show that the reason that usain bolt or tyson gay
or any of these top sprinters are at the level that they're at is because of their genetics
it actually shows more that it has to do with their training regimens what they're doing from
an everyday basis to help build their bodies up that makes it so they're able to perform at the
highest level so really it is nature and nurture that is going to make it so you can perform at the
highest level as always guys thanks for watching this video it's taking me a while to be able to
make this video so if you're still watching right now go ahead and click that thumbs up
down below subscribe the channel if you haven't already and if you're any questions or comments
or recommendations you can leave those down below also check out some of the description to see some
of the programs that we offer and some of the books that we have a lot of things that have
to go primarily into speed development overall but again thanks for watching this was really a
lot of fun to be able to actually make this video and i hope you enjoyed it we'll talk to you soon
