Dear friends,
About the BEST concept - what does it mean?
It is a formula with which we can mathematically calculate the individual efficiency + the effectiveness of the technique for each swim-stroke; the formula has been inspired by the ancient aphorism – Festina lente…! (Suetonius / 69-141 a C.,Les ’Douse Cesars’); see _ Rev. EFS,nr.3/1983, Buch. Rou.
Shortly:
For swimming (it can be adapted for other sports, too), the ‘BEST formula’ (the Biomechanical Efficiency Swimming Test, acronimus) may be described as follows:
[ P.G.I. + (K) ] - [ Time in sec. / 50m + Number of arm-strokes / 50m ] = ....points
the score, in points, of the Biomechanical Efficiency Swimming Test (B.E.S.T.)
(K) = a positive constant, chosen by convention, ex..for BEST formula = 100 points
------------------------ and
P.G.I. = the Personal Gliding Index, computed like this
[ L. + (K) ] - [ Kg.+ Q ]
L. = maximum length of the body in floating position (ventral)
(K) = again a positive constant, chosen by convention, ex. 100 points
Kg. = weight
Q = circumference of the thorax in max. expiration (under armpits)

Definiţii BEST, Les Definitions du BEST,
The BEST Definitions, Der BEST – Definitionen / m.olaru/nov.1999
!/. Tehnica corecta inseamna eficienta de miscare in apa… “testarea eficientei biomecanice la inot”(best) se calculeaza astfel: adun ‘timpul’(‘t’) cu ‘vaslirile’(‘v’) suma lor o scad dintr-o valoare constanta (‘k’)(aleasa aleator = ‘100’) + indicele personal de alunecare (ipa). adica - { 100+ipa } – { timp + vasliri } = ...... p.best
1. La tehnique corecte de la nage implique l’efficience du mouvement dans l’eau.
’’Tester l’efficience / l’efficacite biomecanique dans l’eau’’ [ The Biomechanical Efficiency Swimming Test – B.E.S.T. ....] ce calcule comme suit:
- aditioner le temps (’T’) au les mouvement (par 50m) (’M’), la somme se deduit d’une valeur constante (’K’)[choisie aleatoire, par ex. = 100 point] + l’Indice Personel de Glisse (I.P.G.) c’este a dire, la formule:[100 + IPG ] – [ ’T’ + ’M’] = ...
offre le meilleur resultat, (points BEST).
1/The corect swim-technique means the efficiency of the movements in the water; it can be calculated by this way: add the number of the seconds and the number of the stroke-cicles (by 50m) and this sume will be extracted from the other constant sume provided from adition of the one constant value (K) (100) plus the Index of the personal Gliding (IPG)
!/. *Die korrekte Technik setzt eine effiziente Fortbewegung im Wasser voraus...”Testen der biomechanischen Effizienz beim Schwimmen” (best)
Diese wird wie folgt berechnet: wir addieren die zwei Werte (Zeit und Züge); die Summe wird aus einer Konstante „k” abgezogen ( „k” wird per Zufall ausgewählt = „100”) + persönlicher Gleitindex (pgi).D.h. – { 100+pgi } – { Zeit + Züge } =....... p.best
2/ Obiectivitatea conceptului si a formulei ‘b.e.s.t.’ rezida din urmatoarea logica: ‘adun doua marimi, (timpul / ’t’ + vaslirile / ’v’) care au sens descrescator, - dupa care, le scad din constanta {‘100’ + ‘ipa’} si obtin (facil + repede / mental way ...) valoarea prestatiei in apa’
2. La logique du BEST et son objectivite:
J’additionne deux valeurs, deux quantites , le temps T. et le mouvement M. (des cicles de bras – pour Libre et pour le Dos 2 bras alternative, pour Brasse et pour Papillon une cicle concomitente, seulmant), les valeur qui ont un sens (desirable...!) decroissants et apres je deduis de la valeur constante (anterieur calcule) [ ’100 + IPG’] et j’obtiens (tres facile et vite / by mental way...) la valeur de la prestation dans l’eau.
2/The objectivity of the ‘best formula’ results from this new exercise of logic: ‘we add two value (time+stroke), this values have their sense descendent (!)…, and, after we substrate this sum from one constant value (accidentally (k) = 100 + ipg points)’. in this mod we can obtain (very easy, by mental way) the supreme value of the swimming efficiency.
2/ Die Objektivität des Konzeptes und der Formel „b.e.s.t.” baut auf die folgende Logik auf: „ wir addieren zwei Gröβen, (Zeit + Züge), die einen absteigenden Sinn verzeichnen. Diese werden nachher von der Konstante { „100” + „pgi”} abgezogen. Das Ergebnis (einfach + schnell / mental way...) stellt den Wert der Leistung im Wasser dar.
3/“indicele personal de alunecare” (i.p.a. / este ca un kard-annual) ‘L.’ + (k) – (kgr. + Q) ‘L.’ = lungimea maxima a corpului / pluta ‚(k)’= o constantă cu valoare 100 puncte ‘gr.’ = greutatea in kilograme / + ‘q.’ = diametrul/cm. subaxilar in expiratie profunda – the “index of personal gliding “ (i.p.g.)
3. L’indice de la Glisse dans l’eau (IPG) este une valeur constante, comme un card banquare, qui le calcule annuellement:
’L.’ + (encore une ’K’ de 100 points, aleatoire...!) la somme se deduit d’une autre somme resulte par addition de ’Kgr.’ + ’Q.’, c’est a dire:
[ L. + (K) ] – [ Kgr. + Q ] =
la valeur anuelle plus constante de IPG en points....
’L.’ – longuer maximale du corp entierre
(la possision fondamentale de nage - planche de flotation du corp sur le ventre ou sur le dos verrifie sur terrre);
(k) – une ciffre constante, aleatoire, d’une valeur de 100 points;
’Kgr.’ - Kilogrames du corp, sur terre;
’Q.’ – le diametre en cm. de la cage thoracique en expir profonde, et le resultat de cette formule que l’on nomme – Indice Personel de Glisse (IPG) dans l’eau, avec ses point et d’une valeur constante, annuelle.
3/The index personal of gliding (ipg) is lake a ‘credit card’ (the validity is minimum one year): with this ipg we can organize the series of the race in perfect ‘faire-play’ (indifferent of the sex or age) the competitors with same or appropriate values will be introduce in the same series …the periodical calcul of this ipg formula is found with regarding to the hydrodynamics principle (reynolds+froude),so: ‘’from the value of the maximum longer of the body (ventral float position)(L.) / in additions with another accidentally value constant (k=100), we will substrate the sum of the nr. of kgr. (weight) with the Q. (nr. of cm. of the circumference of the upper thorax in deep expiration). ‘L.’+(k) – ( ‘kgr.’ + ‘q.’)
3/ „Der persönliche Gleitindex” (p.g.i./ ist wie eine Kreditkarte, die 1 Jahr gültig ist (kard-annual)). „L” = die maximale Körperlänge / ventral float position; „k” = eine Konstante mit dem Wert von 100 Punkten; „kgr” = das Gewicht in Kilogramm / + „Q” = Durchmesser/cm des oberen Brustkorbabschnittes bei tiefer Ausatmung
4/ aplicabilitatea ‘annual kard-(ului)’(ipg – index of personal gliding ), indiferent de sex si chiar de varsta subiectilor…, este data de faptul ca criteriile alese, pentru folosirea sa ca instrument de departajare / organizare a intrecerilor de inot sportiv , sunt cele induse in selectia naturala:
# cu cat un corp este mai lung (l.),
# cu cat un corp este mai usor, (gr.)
# cu cat un corp este mai ingust (q.)
cu atat mai eficient pluteste, aluneca sau inainteaza !
4. L’application (calculation) annuelle du kard IPG –non peliee du sex, genne, et de l’age du suject (!), sont donnes comme une unique critere pour departager / organiser les eventuellle competitions (des series avec une real ’fraire-play’) de concurs de ’excelence tehnique de nage’ par 50m, car ce sont les criteres induits par la selection naturelle:
- plus que le corp est long .....
- plus que le corp est leger....
- plus que le corp est etroit ....
cet corp peut glisse et avance plus bien, plus efficace !
4/The valability of the index personal of gliding (ipg) results from that – all criteria selected to make the series for the challenge was selected from the normal natural selection:
when the longer of the body is big…
when the weight of the body is light...
when the frontal section of the body is small
the float, the gliding and the swimming speed will be more efficiency to advance better with one correct technique !
4/ Die Gültigkeit des „kard-annual” (pgi – persönlicher Gleitindex), unabhängig von Geschlecht oder Alter der Angewiesenen..., ist darauf zurückzuführen: die Kriterien, die ausgewählt wurden, um zu bestimmen, inwiefern die „annual kard” als Instrument zur Unterscheidung von Leistungen oder Veranstaltung von Schwimm-Wettkämpfen verwendet werden kann, gehen auf die natürliche Auswahl zurück:
je länger ein Körper ist (l.),
je leichter ein Körper ist (kgr),
je schmaler ein Körper ist (q.),
desto effizienter wird er schwimmen, gleiten oder sich im Wasser fortbewegen.
** The numbering of rowing cycles can be made by visual inspection or with a mechanical/electronic(?) counter that could avoid the errors (see attach nr.2).
****** Die Zählung der Ruderungsabläufe kann frei (visuell) durchgeführt werden oder mit Hilfe eines mechanischen/elektronischen (?) ‘counter’s, der die Kopfzählung vereinfachen soll und mögliche Fehler vermeiden soll (Varianten).

In Sept. / 99, I imaginate one other formul ‘Personal Gliding Index’ / PGI = L – ( Kg. + Q)
this mean: L= the Body lenght in gliding position (with the arms stretched forward); Kg.= Weight; Q = Nr. of Cm. between the under-armpit circumference (or other antropomophic measurmeants - angle, degree s.a –see Froude, Reynolds Nr.in hidrodinamics laws).
* This 2 new ‘instruments’ (the ‘BEST’ and ‘PGI’ formuls) can be use in one new kind to make testings and classification among the swimmers in to 50m Events; the all competitors / series, will be organisates by the one ‘PGI-annual-card’, combinated both: PGI – (T + S) this is one method to make the control of the moving efficincy and the organisation in the equall series among the swimmers without age and sexes criterions, only by the PGI –annual Card who can by easy recalculate in every years....
