Ieri
Amândoi sunteţi
membri ai grupului Professional Swim Coach pe LinkedIn.
Dear Clive - American sistem of
"'áge groups races""'is very good because 0fer to so many
childrens one dream > ''try to be like 'michael'; but one very small group
will comme true ''elite swimmers'''..., other childrens lost swimming and not
rarely. have some frustration. For this childrens + old swimmers/adults I
formulate one new concept to make swimming - effyciency+better technic (sorry,
me inglish is very poor).

Astăzi
Good morning Mircea, greetings. Where
do I start? I really don't understand the point of the equations?
02:55

Ooops! Sorry, I pressed something and it posted itself! Let's
start again: Good morning Mircea, greetings. Where do I start?
·
I really don't understand the point of the equations? Let me try
to deconstruct the formula so that you can tell me if I have understood it
correctly: K is your constant. What is it doing? It serves no purpose
whatsoever. And you add it twice at separate stages – first when calculating
the PSI and again when calculating the BEST score. Why not simply add 2*K
somewhere?
·
Why not simply omit it? L – is this in a ‘streamline’ position
(i.e. arms extended as in a push off) or simply standing height measured for
some reason while floating? Why floating?
·
Weight and thorax circumference completely baffle me – why are
they included? Thorax will show some indication of frontal area but so what?
Weight will tell you how heavy you are when you’re NOT in the water. So what?
When I do the calculations I find that the indexed effect of significant
improvements in speed and/or cycle count are subdued because of the inclusion
of the other factors. Surely effectiveness and efficiency are ONLY concerned
with speed and cycle count? If the body length increases the BEST index rises.
If the weight decreases the BEST index rises. If the thorax circumference
decreases the BEST index reduces. If the time improves the BEST index rises. If
the cycle count decreases the BEST index rises. So, in order to increase the
index number the swimmer can become longer, lose weight, expand the chest, swim
faster, or use fewer strokes. Who cares about three of those? Only two are of
importance. Surely it is simpler to just time, say, a 200 and count the
strokes? That will give you two ‘baseline’ numbers. Next time if the time is
constant and stroke count has decreased then the swimmer is more efficient; if
the stroke count is constant and the time decreases the swimmer is more
effective. That’s it. What else does the swimmer or coach need to know? There
is nothing else. Time and stroke count are all you need.
Bună dimineața Mircea, salutări. De unde să
încep? Eu chiar nu înțeleg punctul de ecuațiile?
02:55
• Ooops! Ne pare rău, am apăsat ceva și ea însăși postat! Să începem
din nou: Bună dimineața, Mircea salutări. De unde să încep? Eu chiar
nu înțeleg punctul de ecuațiile?Lasă-mă să încerc să deconstruiască formula
astfel încât să puteți să-mi spui dacă am înțeles corect: K este constantă
ta. Ce o face? Acesta servește nici un fel de scop. Și tu adauga
de două ori la diferite etape - prima la calcularea PSI și din nou atunci când
se calculează cel mai bun scor. De ce nu pur și simplu se adaugă 2 * K
undeva? De ce nu pur și simplu omite? L - este aceasta într-o poziție
"Streamline" (de exemplu, arme extins ca într-o împingere off) sau
pur și simplu înălțime măsurată pentru un motiv oarecare timp plutitoare în
picioare? De ce plutitoare? Greutate si circumferinta toracelui
șicane complet mine - de ce sunt ele incluse? Torace va arăta anumite
semne de zona frontală, dar atât de ce? Greutate vă va spune cât de greu
esti atunci când nu sunteți în apă. Şi ce dacă? Când fac calculele mi
se pare că efectul indexate de imbunatatiri semnificative in viteza și / sau
numărul de ciclu sunt supus din cauza includerea celorlalți factori. Cu
siguranță eficacitatea și eficiența sunt doar în cauză cu o viteză și numărul
de ciclu? În cazul în care lungimea corpului crește CELE MAI BUNE crește
index. În cazul în care greutatea scade CELE MAI BUNE crește index.Dacă
circumferința toracelui scade cel mai bun indice reduce. Dacă timpul
îmbunătățește CELE MAI BUNE crește index. În cazul în care numărul de
ciclu scade CELE MAI BUNE crește index. Deci, în scopul de a crește
numărul de index înotătorul poate deveni mai, pierde în greutate, extinde
piept, inota mai repede, sau de a folosi mai puține accidente vasculare
cerebrale. Cui îi pasă de trei dintre cei? Doar două sunt de o
importanță. Cu siguranță este mai simplu cu doar timp, să zicem, un 200 și
numără accident vascular cerebral? Care vă va oferi două numere "de
bază". Data viitoare în cazul în care timpul este constant și numărul
de accident vascular cerebral a scazut, atunci înotătorul este mai
eficientă; dacă numărul de accident vascular cerebral este constantă și
intervalul scade înotătorul este mai eficientă. Asta e. Ce mai
înotătorul sau autocarul trebuie să știți? Nu este nimic
altceva. Timp și numărul de accident vascular cerebral sunt tot ce ai
nevoie.
Wrong?
Google Tra
My luck was that someone wrote to me on Linkedin and so I saw
your answer (I do not really use Linkedin network...)
It’s been a while since I supported the BEST Concept and here I
try to objectively justify myself, with a reasonably applied and logically
approved mathematics.
You put your big heart in this - your answer makes it clear that
you had good will and you managed to read the whole text - congratulations ...
I will try to explain, but please have patience ...: This
formula was designed especially for children who are not as smart as the adults
....
So in short -
If you do as you have remarked (correctly!) ... the total sum of
the number of seconds plus the number of tempo - their value will be the better
the higher the result is below ...; I think children cannot understand this
("a lower result will be good ..."), and this is why I have
introduced theoretically, formally, constant 'K' (= 100) which enables the
result calculated to have a positive value. I admit that I used this at the
release of the BEST Concept (1983) and it was forced and unrealistic; so I
admitted that the introduction of the constant 'K' is artificial and searched
to replace it with another constant ... thus I reached PIG (Personal Index of
Gliding ...?) in 1999 (there were decades of searching until I found it ...).
-------------------------
We all know that everyone has a personal capacity to glide. This
capacity results from some biological indicators, which vary from one individual
to another but have a special meaning in connection with the body which moves
through the water ....
I will explain right away ... but until then I hope you accept
that a good PIG value is important in achieving a high speed (a) and is a
constant value, at least for a year (b).
If I decrease the value out of the PIG constant ('Time' +
'Tempo'), the more you have a smaller value ... I will have a higher and
therefore credible constant (PIG) in the mind of my beginner... + for me is a
value which definitely say about what my swimmers’ efficiency is and so I can
start a 'negotiation' of his way to swim... ..
I hope I have cleared up on my judgment that takes into account
the need to provide a child credible numbers (A), that can show what is the
mathematical value of the efficiency of the movements in water (B) by using the
technique of a swimming stroke, as required by FINA regulations / TSC (4 basic
strokes).
Thus, I assume that the values of 'Time' and 'Tempo' accepted by
two of us, I mean that that if you mathematically decrease their sum out of the
PIG constant, the value gives us an idea about the effectiveness of the
person who is swimming. Do not forget that we talk about all kind of people,
some fat, some taller, etc.
------------------------
So PIG is calculated (once a year ...) as follows:
'L' = is the longest that a swimmer’s body can have in the
water, ie floating ventral float ...; to be more simple I can take, only the
Height as you propose, but by doing I will be deprived of two important
milestones for swimming = 'long hand' and 'foot size'; So I prefer the constant
value of the body stretched out in the water from which I will decrease (just
like the calculation of efficiency) the sum of the body weight - Gr. (out of
the water) plus the number of centimeters of the circumference measured under
arms -Q.
"Gr" = is body weight out of the water but we know
that in the water this weight will drop and the body, according to Archimedes'
principle, it will be lighter so it will float easier; a heavy body will have
difficulty to float and glide ... a light one will be favored. To calculate the
'specific weight’ of a body in the water, requires a large hassle, this is why
I chose the easiest way ....
'Q' = represents a landmark much linked to movement, meaning
that the water can oppose resistance against the progress of the body
(theoretically, even shipbuilders, admit that resistance will be smaller.. as
the ratio between the body length and overall width has a value given by
Froude, Reynolds' formula, ie radical in length / width - but these
calculations are simply impossible to do for a simple coach ... even for Bob
Bowman (sic), so I chose a significant and natural value - Circumference
measured under arms (like a tailor who makes a suit)
Finally PIG equals value 'L' amount minus the number of
kilograms 'Gr' plus the number of centimeters (Q), so PIG = L - (Gr. + Q) ....
constant values for at least one year.
Anyway,
thanks for the opportunity you gave me once again to plead for 'eureka' My life
coach - BEST concept dated when writing about something not in any work for
swimming (1983)
With great
sympathy

Text de raspuns pt
Clive…..
====================
Norocul meu
a fost ca cineva mi-a scris pe Linkedin si asa ma vazut raspunsul tau (eu nu
prea folosesc reteau Linkedin…)
De mult timp
nu am mai sustinut cauza Conceptului BEST si iata ca incerc sa ma adun pentru a
ma justifica in mod obiectiv, rational sub o forma matematica aplicata si
admisa ca logica.
Ai pus
suflet mare in corespondenta ta, este clar ca ai avut bunavointa si ai reusit
sa citesti totul - te felicit…
Incerc sa ma
explic, dar te rog sa ai rabdare…: aceasta formula a fost destinata, mai ales,
copiilor si a celor care nu sunt asa de destepti precum suntem noi adultii….
Deci, pe
scurt -
Daca fac asa
cum ai remarcat tu (corect !)…, suma numarului de secunde plus a numarului de
tempo, valoare lor va fi cu atat mai buna cu cat rezultatul este mai mic…; eu
cred ca copiilor poate sa li se para neconvingator (“un rezultat mai mic sa fie
unul bun…”), de aceia am introdus theoretic, formal, constanta ‘K’ (=100) care
facea posibil ca rezulatul calculului sa aibe o valoare pozitiva, in crestere…;
recunosc ca acest lucru l-am folosit la debutul lansarii Conceptului BEST(1983)
si era fortat si nerealist, am admis ca introducerea constantei ‘K’ este artificiala
si am cautat s-o inlocuiesc cu alta constanta…, asa am ajuns la PIG (Personal
Index of Gliding…?)in 1999 (au fost zeci de ani de cautari pana am gasit
remediul…).
-------------------------
Toti stim ca
fiecare om are o valoare personala a capacitatii de a aluneca. Aceasta valoare rezulta
din niste indicatori biologici, care variaza dela un individ la altul dar care au
o insemnatate aparte in legatura cu corpul care inainteaza prin apa….
Mai voi
explica imediat…, dar pana atunci sper
sa accepti ca o valoare buna PIG este importanta in realizarea unei viteze cat
mai ridicata(a) si este si o valoare constanta, cel putin pentru un an de zile(b).
Daca scad
din constanta PIG suma (‘Timp’+’Tempo’), cu cat voi avea o suma mai mica… imi
ramane o constanta (PIG) mai mare si deci credibila in mintea incepatorului meu…
+ pentru mine este o valoare care imi
spune cert cam ce eficienta are sportivul meu la inot si asa pot incepe o
‘negociere’ a felului sau de a inota…..
Sper ca
te-am lamurit asupra rationamentului meu care are in vedere nevoia de a oferi
unui copil cifre credibile(A), si faptul ca acestea pot arata care este
valoarea matematica a eficientei de inaintare in apa(B) folosind tehnica unui
stil sportiv de inot, asa cum prevede regulamentul FINA/TSC (cele 4 stiluri de
baza).
Astfel, presupun
ca valorile ‘Timp’ si ‘Tempo’ sunt acceptate de noi doi, adica daca scad
mathematic suma lor din constanta PIG, valoarea ne da o ideie despre eficienta
celui care inoata. Sa nu uitam ca vorbim despre fel de fel de oameni, unii
grasi, altii inalti, etc.
------------------------
Deci PIG se
calculeaza ( o singura data pe an…) astfel:
‘L’ =
reprezinta lungimea cea mai mare pe care o poate avea un corp de inotator aflat
in apa, adica in plutire ventrala intinsa…; pot sa iau, simplu, doar Talia, Inaltimea
cum propui tu, dar facand asa ma lipsesc de doua repere importante pentru inot
= ‘lungimea palmei’ si ‘marimea labei piciorului’; deci eu prefer valoarea
constanta a a corpului aflat intins in apa din care voi scadea (exact ca la
calculul eficientei) suma Greutatii corporale- Gr. (pe uscat) adunata cu Numarul
de centimetri a circumferintei sub axilare -Q.
“Gr” =
reprezinta, firesc, greutatea corpului pe uscat dar stim ca in apa aceasta
greutate va scadea iar corpul, conform principiului lui Arhimede, va fi mai
usor si deci va pluti mai usor; un corp greu va avea dificultati la plutire si
inaintare…, unul usor va fi avantajat. A calcula ‘greutatea specifica’ a unui
corp aflat in apa, presupune o mare bataie de cap, de aceea am ales cea mai
simpla cale….
“Q” = reprezinta un reper mult legat de inaintare,
adica de rezistenta pe care o poate opune apa impotriva inaintarii corpului (
theoretic, chiar constructorii de nave, admit ca rezistenta va fi cu atat mai
mica.., cu cat raportul intre lungimea corpului si latimea sa maxima are o
valoare data de ‘formula Froude-Reynolds’, adica radical din lungime/latime – dar
aceste calcule sunt imposibil de facut pentru un simplu antrenor.., chiar si
pentru Bob Bowman(sic), asa ca am optat pentru o valoare semnificativa si
fireasca - Circumferinta sub-axilara /
ca la croitor cand iti faci un costum de haine)
In final PIG
este egal cu valoare ‘’L’ minus valoare sumei Numarului de kilograme ‘Gr’ adunat
cu Numarul de centimetri(Q), adica PIG = L –(Gr.+Q)…. puncte constante timp de
minimum un an calendaristic.
------------------
Asa ca azi, in
2015…, Formula BEST, in ultima sa varianta…(nu uita ca materialul trimis tie
dateaza din 2010, asa am impresia…) este asa:
BEST = PIG –
(Timp+Tempo)… puncte de eficienta
DAR, iti
spun ceva care nu-l spun nimanui. Este ‘cadoul secret’ oferit celor care cred
in Conceptul BEST….
I/ Sa stii
ca cei care inoata avand conduita de a sprinta folosind economie de vasliri…. reusesc
sa PERFECTIONEZE admirabil tehnica. Deci Conceptul BEST poate fi folosit, mai
ales, pentru a avea un bun inotator cu tehnica perfecta.
II/ La fel,
Conceptul BEST poate fi util celor din categoria ‘masters’; sunt foarte multi oameni
care au invatat sa inoate dar nu au ajuns campioni olimpici…, cei mai multi.
Acestia,
daca adopta conduita de a inota repede cu miscari putine vor ‘deveni proprii
lor campioni’, ei isi vor imbunatati tehnica…, isi pot calcula mental valoarea
prestatiei la un moment dat…., + PIG,
valoarea sa, poate fi folosita de arbitri, la alcatuirea unor serii de
intrecere perfect egale din punct de vedere somatic si deci pline de
‘faire-play’
Eu incerc sa
dau acest text, destinat tie, la un traducator bun de limba engleza (multi nu
cunosc terminologia noastra..), sper sa reusesc. Daca TU ai incerca sa-l
traduci si sa-l faci inteligibil pentru
vorbitorii de engleza… vei avea dela mine tot ce doresti…. Succes si Doamne
ajuta !
Oricum iti
multumesc ca mi-ai dat ocazia, inca odata, de a pleda pentru ‘evrika’ vietii
mele de antrenor – Conceptul BEST, datat cand despre asa ceva nu se scria in
nicio lucrare de inot (1983)
Cu mare
simpatie
