read the link above on history of them , gives 1998 as the year for your first basic type.
then mid 2000's for other types that more specific to building muscle .
so put it altogether gives them more than long enough to figure how to best use
by time certain bolt comes along , noticed more androgenic type
had added offshoot that gave market increase in speed endurance and that could
be used on younger athletes without any detrimental effects .
and then with muscle specific sarms complemented them and never need to go
near steroids for strength gains and cover all variables for sprints .
can already easily buy online , as for juniors it is beyond obvious that something
diiferent in the water ,no longer a rarity and as said the consistancy also stands out .
as stated above for many of them it is key to get them on it when young enough
as no gaurantee that would be a high per centage fast twitch athlete naturally to varying degrees
why the rarity before , especially in non black groups afraid this is the reality ,
also clarify that previously gains in speed would usually come later in career from
steroid use usually also with heavy lifting ,not even needed now ,why so obviously different .
obviously assuming here that sports specific exerise is used in conjunction with ,ie no quick fix ,
still have to sprint train correctly to change over muscle fibre type but will make the progression where most
previously alot would stall and see no gains in speed no matter how much training do .
again muscle fibre most plyable at developemental age , if older only can expect similar
gains if naturally muscle fibre predisposed to high per cent.
so androgenicity , muscle type and speed endurance
can be kind of interchangeable .
any athlete can benefit and get gains in speed
but never be elite sprinter and to be that need to
upp androgenicity at correct time as young adult in conjunction
with explosive sport and will give athlete the correct max muscle type
that will be able to maintain for alot of carreer and make the elite grade.
Question , sarms might level playing field in terms of any differences
in race in the sprints but still the media and society will want
a 100m that suits there multicultural agenda , so still dont expect any major change come that .
they make the sprints a level playing field is real main point . intellect overcoming the physical could say.
and QUESTION ,if differences in androgen receptor occur naturally between athletes will said athletes get more of enhancement ,
from what seeing no, variables seem to be same ,all can be maxed out and need balance .
androgenicity ,strength and now extra variable of added height
that made possible by it .
to be running 9.58 will need all of them.
