Antrenamentul copiilor ...

" În ceea ce privește pegatirea fizica pe uscat pentru formarea unui nivel ridicat al formarii rezistenta , parintii si antrenori ar trebui să țină mereu în vedere faptul că copiii nu sunt adulți în miniatură ", a declarat Martin Reuters Health .
Guidance is key for kids' resistance training: experts

(Reuters Health) - Resistance training is good for kids, but needs to be supervised and tailored for them by a qualified professional, according to a consensus statement by 20 doctors and fitness experts.
The statement appears in the British Journal of Sports Medicine and is endorsed by the American Academy of Pediatrics, the International Federation of Sports Medicine and the U.S. National Collegiate Athletic Association (NCAA).
Resistance training - which can include light free weights, resistance bands or medicine balls, as well as push-ups and other body-weight-bearing exercises - can benefit young bodies and prepare them for active lives, the authors point out.
"You can look at the data from the Centers for Disease Control, kids are becoming less and less fit all the time," said Dr. Tim Hewett, director of the Sports Medicine Biodynamics Center at the University of Cincinnati, who was not involved in the statement. "There are lots of problems related to our current lifestyles."
Lack of strength and overall fitness, cardiovascular and musculoskeletal strength all contribute to poor health for kids, and resistance training can be a great option to help, but moderation is key, he told Reuters Health.
Though many parents fear their children will be injured during exercise or will damage their growing skeletons, childhood is actually the best time to use weight-bearing activity to build bone mass and kids are less likely to suffer sprains than adults, according to the statement.
Programs designed to promote conditioning and correct form for specific sports can also reduce the risk of injuries by 50 percent in kids and teens, the authors write.
"Clearly, participation in physical activity should not begin with competitive sport but should evolve out of preparatory fitness conditioning that is sensibly progressed over time," they write.
But these activities need to be supervised by "qualified professionals," like trainers or coaches, with strength and conditioning certifications.
These leaders need to know how to effectively communicate with kids and teens, as well as what exercises are best for kids and teens, and "how much is too much."
Position statements in support of resistance training like this one make it easier to inform parents and coaches who may still be hesitant, said Jeff Martin, who co-founded CrossFit Kids, a branch of the popular and sometimes controversial training program geared to kids from preschool age and up.
"With respect to resistance training, parents and coaches should always keep in mind that children are not simply miniature adults," Martin told Reuters Health.
Children, especially the youngest ones, benefit most from doing many reps of little or no weight, he said.
Hewett, a former power lifter, agreed with that premise, but expressed concern that CrossFit in particular may be too intense for kids.
"We have to get our kids more active but we can't overdo it," he said.
Kids need to have fun to be engaged, and can vary widely in their ability to pay attention and focus during sets of many reps of the same movement. When they drop weights, he said, they could injure themselves.
Martin recommends that preschool kids never use weights, and should focus instead on fundamental movements like squats.
The American Academy of Pediatrics recommends that eight year olds can start using light weights, but children mature at vastly different rates, Martin says, and some five year olds in his program start using very light objects or dumbbells.
"The key points are moderation, supervision and qualified professionals," Hewett said.
He and Martin agree that "qualified professionals" need more than just certifications, they need experience working with kids so they can assess a child's developmental and emotional maturity, since that can often be an important factor in how much is too much for each child.
"Parents should watch their children's trainers and see how the children react to them. Do they relate well and vice versa?" said Martin. "All the qualifications in the world will not help someone who cannot speak the language of the children or teens in their care."

Copii sunt vulnerabili la capitolul concentrare...; foarte multi antrenori folosesc antrenamente lungi, cu exercitii de anduranta , monotone, pentru ca copilul sa obtina un nivel bun, ridicat de rezistenta; acest lucru este nefiresc pentru varsta mica iar lipsa concentrarii duce la instalarea unor stereotipuri gresite de miscare, de tehnica, greu de remediat dupa ce s-au instalat......

Eu am gasit o alta maniera de a le creste rezistenta dar prin scurte sprinturi [de regula facute pe latimea bazinului] cu varietate mare de exercitii de tehnica [brate, picioare]. selectate defalcat din coordonarea globala a celor 4 procedee oficiale de concurs.

Metoda se recomanda a fi folosita cu grupe mari de copii care lucreaza CONCOMITENT, in grup, iar antrenorul poate sa intervina INDIVIDUALIZAT asupra unor executii gresite dar care nu s-au instalat inca ca greseli adevarate. Usurinta de incadrare in acest regim face ca toti incepatorii sa fie foarte incantati si astfel nivelul de receptivitate, de concentrare este optim, adica cel dorit de noi....

Teoretic, specialistii au numit aceasta noua maniera 'metoda concomitenta' care are drept obiectiv trecerea rapida de la starea de incepator la starea de inotator avansat care sa poata participa la concursuri cu probe adecvate varstei lor [ de regula dupa 11 ani, asta inseaman ca incepatori aveau o medie de 10 ani].  

Children are vulnerable in terms of concentration ... ; very many coaches use long training with endurance exercise , monotonous , for the child to obtain a solid , high resistance , it is unnatural to young age and lack of concentration leads to installation erroneous stereotypes of movement, technique , hard to remove after they have installed ...... 

I have found another way to increase their strength but the short sprints [ usually made on the pool width ] with variety of technical exercises [ arms, legs, elementary combinations ] . Selected deducted from the global coordination of the 4 official stroks of competition. 

The method is recommended for use with large groups of children working in group CONCOMITANT + and coach may intervene on some wrong executions INDIVIDUALISED until they have not yet installed the real mistakes . The ease of nesting in this scheme is that all beginers will be very hapy, wel excited and thus the level of receptivity , concentration is optimal , ie, the desired new .... 

Theoretically, experts have called this new way ' Simultaneous method ' which aims to pass easily from state to state swimmer advanced beginner who can contest with appropriate evidence of their age [ usually after 11 years , that means you beginners had an average of 10 years] . 

Have a nice day

Igiena bazinului ,,,

"What measures have you made to protect your pool users? I look forward to hearing your comments." [selected text from "About Swim " by Mircea Olaru, 2007 , Bucharest, Roumany]

Cap. Swimming pools:
Among the minimum requirements to be fulfilled by any basin include those relating to:
- Water , which must be equal to the drinking water ( pH 7.2 ) ,
- With a minimum temperature of 24 C (full contest rules set by FINA ) exceeding 27 C ( usual time encountered when lessons lasting 1.5-2.0 hours) lower or higher temperatures are not recommended for achieving regime swimming sports
- Good water clarity (transparency ) with purity ensured by physicochemical tartare with disinfectants (hypochlorite , ozone ) coagulant ( alum ) that destroy algae ( copper sulfate ) allowed the water entering the system content filtering to be suspended between 10-30 mg / l ;
- Air , polluted industrial basins covered , it must have a higher temperature water to 5 C ( controlled to 1.5 m above the water level ) , the humidity of less than 60% (to prevent condensation ) ;
- Natural lighting should be provided by placing the long edge of the basin construction in east-west direction and the artificial is homogenized at a power of 50-150 lux ;
- Acoustics - will be adjusted to prevent the formation of echo ( sound waves applied absorbent material on the sides of the basin ) ;
- Circular space - on each side of the tank at least 2 m and is clad with ceramic slip to a slight tilt to the outside edge to prevent water in the tank ;
- stands to the public - at least one long edge of the basin with facilities for athletes and differentiated public stewardship ;
- Separate changing rooms for both sexes with access to the bathroom , shower , sauna, indoor transit ;
- Social group - circulation spaces and public spaces , athletes , trade specialty items or food tv- radio transmission facilities , telephone communication and other facilities due to the affluence of visitors and applicants ( parking, transport stations joint , etc.). . 

text selectat din lucrarea "Despre inot" by Mircea Olaru, 2007, Cap. Bazinul de inot:
Printre cerinţele minimale pe care trebuie să le îndeplinească orice bazin se numără cele referitoare la:
                - apă, care trebuie să fie  egală celei potabile (pH-ul 7,2),
                - cu o temperatură de minimum 24 C (normă de concurs stabilită prin regulamentul FINA)  maximum 27 C (normă uzuală întîlnită în cazul lecţiilor care durează 1,5-2,0 ore); temperaturi mai mici sau mai mari nu sînt recomandate pentru realizarea regimului de înot sportiv,
                - apă cu claritate bună (transparentă), cu puritate asigurată prin tartarea fizico-chimică cu substanţe dezinfectante (hipoclorit, ozon), coagulante (alaunul), care distrug algele microscopice (sulfatul de cupru); se admite ca apa care intră în sistemul de filtrare să aibă conţinutul de suspensii între 10-30 mg/l;
                - aer, nepoluat industrial, în bazinele acoperite, trebuie să aibe o temperatură superioară apei pînă la 5 C (controlată la 1,5 m deasupra nivelului apei), umiditatea de maximum 60% (pentru prevenirea fenomenului de condensare);
                - iluminarea naturală să fie asigurată prin amplasarea din construcţie a laturii lungi a bazinului pe direcţia Est-Vest iar cea artificială să fie omogenizată la o putere de 50-150 luxi;
                - acustica - va fi reglată pentru prevenirea formării ecoului (materiale absorbante a undelor sonore aplicate pe pereţii laterali ai bazinului);
                - spaţiul de circulare - pe fiecare latură a bazinului de minimum 2 m, fiind placat cu gresie antiderapantă la o înclinare uşoară spre exterior pentru a preveni scurgerea apei marginale în bazin;
                -tribune pentru public - cel puţin pe o latură lungă a bazinului cu amenajări destinate dirijării diferenţiate pentru sportivi şi public;
                - vestiare separat pentru ambele sexe cu acces la grupul sanitar, duşuri, saună, încăperi de tranzit;

                - grup social - spaţii şi încăperi destinate circulaţiei publicului, sportivilor, comerţului cu articole de specialitate sau produse alimentare, facilităţi de transmisie tv-radio, comunicaţii telefonice precum şi alte amenajări ca urmare a afluenţei de vizitatori şi solicitanţi (parcare auto, staţii pentru transport în comun, etc.).

Chiar cat de mare ar fi bucuria... microbii nu se sinchisesc
accesul publicului este dirijat strict - nu are ce cauta pe marginea bazinului
Iata ce frumos este interiorul unui bazin, nou

Rapid learning how to organize the 4 official procedures sports swimming in a deep water pool , with children who were younger than 10 years [ " simultaneous method " ] .
By Mircea Olaru
Efficient organization entails practice in speed for a short distance, usually the width of the pool (!) , Numerous exercises , technical breakdown of the 4 methods.

Why is this possible - as biomechanical analysis of four methods of competition * ( Freestate , backstroke , Dolfin , Breastroke ) shows that most movements resemble each other , as shown in " Counsilmann , Propeler mouving " (a) and that some fundamental changes due to change swimming position (ventral , dorsal ) ( b ) or differences in coordination of limb movements ( alternative / Free , Back or simultaneous / Dolfin , Breas . ) ( c ) .

It follows that learning sports swimming in deep water pool can be done by repeating random (! ) Different forms of rowing , with exercises broken , split , the overall coordination of the 4 methods ( !) , Obviously with those children know , at least , jump in standing water (a) and then to ' tread water ' ( b ), so with those who have passed the stage of " initiation elementare'şi no longer in danger of drowning but who can not swim sport .
" Simultaneous method " is a method that can be applied to single (A ) easily to large groups of children ( B ) who are asking simple execution , in speed, the distance - width boards pool , children being arranged in series , with exercises drawn from the natural progression of training ' water felt ' and ' habit of floating and submit regular '.

Its application enables and measures of individualization through personalized guidance for those who make mistakes - [ repetition exercises are not performed correctly (a ) explain / demonstrate the exact address , especially in the breaks between repetitions , the details of unsuccessful movements ( b ) and even usual imitation of those who swim better (c )] .

A lesson with the simultaneous method ' , looks like a little practice , approx. 45 min . ; Reps with breaks are comfortable , it relies on the spirit of the race of each child , so that along with various forms of ' training ' appearing and elements of ' education ', children begin to act like ' mini athletes ' , prospective competitors over the years ...
Over this way of working with children should have a coach , always in focus , the basic principles of sports training [ from easy to difficult , from simple to complex , etc. . ] And conditions that arise in ' Training scheduled ' method encountered schooling system [ie , do not go to a higher stage in a difficult year , only after you have proved that you can achieve the correct ( !) previous exercices ] .

But the most important objective of this way to form future performance swimmers is that both ' Dosage load ' exercises as well as ' graduation complexity ' their exclude " Forcing Early ' of the main functions of the body [ cardio -respiratory system ] =" I try to swim properly as an athlete ... but not to make , at any price, record after record . " It is known that many ' champions juvenile ' as soon as get the first medal quickly get to Blaze and not willing to become what it originally meant .

For this reason , I recommend , ' method concomitant ' and training organization in the sporty atmosphere of competition but so far they have limited capacity beginners .
Since this organization ... I am convinced that applying this method, besides its sporting prowess acstigul can see that this leads to a real profit management: Most beginners, more money ... and saying 'time is money' comes true again./

Cum trebuie să organizezi învățarea rapidă a celor 4 procedee oficiale de înot sportiv într-o piscină cu apă adîncă, cu copii care au varsta mai mica de 10 ani [“Metoda concomitenta”].
Organizarea eficientă presupune exersarea, în viteză, pe scurtă distanță, de regulă pe lățimea bazinului(!), a numeroase exerciții, defalcate din tehnica celor 4 procedee.
Dece este posibil acest lucru - deoarece analiza biomecanică a celor 4 procedee de concurs*(Freestile, Backstroke, Dolfin, Breastroke), arată ca majoritatea mișcărilor seamană între ele, așa cum rezultă din   “Counsilmann, Propeler mouving” (a) și că unele modificări se datorează schimbării poziției fundamentale de înot (ventrală, dorsală)(b) sau a deosebirilor de coordonare ale mișcărilor membrelor (alternative/Free, Back sau simultane/Dolfin, Breas.)(c).
Rezultă că învățarea înotului sportiv, în bazin cu apă adîncă,  se poate face prin repetarea aleatorie(!), a diferite forme de vîslire, cu exerciții defalcate, pe părți, din coordonările globale ale celor 4 procedee(!!), evident cu acei copii care știu, minimum, să sară în apă în picioare(a) și care, apoi, să ‘calce apa’(b), deci cu cei care au trecut de etapa ‘inițierii elementare’și care nu mai sunt în pericol de a se îneca, dar care nu știu să înoate sportiv.
“Metoda concomitentă” este o metodă care se poate aplica unitar(A), cu ușurință la grupe mari de copii(B), carora li se cer executii simple, in viteza, pe scute distante -latimea bazinului, copiii fiind organizați pe serii, cu exerciții  alese din progresia firească de formare a ‘Simțului apei’ și a ‘Deprinderii de a pluti și înainta regulamentar’.
Aplicarea ei permite și măsuri de Individualizare prin indicații personalizate pentru cei care gresesc -[repetarea exercițiilor care nu sunt realizate corect(a), explicarea/demonstrarea cu adresa precisă , mai ales în pauzele dintre repetări, a detaliilor miscarilor nereusite(b) și chiar obișnuita imitare a celor care inoata mai bine(c)].
O lectie cu ‘metoda concomitenta’, arata ca un mic antrenament -cca. 45 min.;  se fac repetări cu pauze confortabile, se mizează pe spiritul de întrecere al fiecărui copil, astfel că alături de numeroasele forme de ‘instruire’ apar și elemente de ‘educație’, copii începînd să se comporte ca niste ‘mini sportivi’, viitorii competitori de peste ani…
Peste acest mod de a lucra cu copii, antrenorul trebuie să aibe, mereu,  în atenție, principiile de bază ale instruirii sportive [ de la usor la mai greu, de la simplu la complex etc.]dar și condițiile care apar în cazul ‘Instruirii Programate’ metodă întalnită în sistemul de invățămînt școlar [adică, nu treci la o etapa superioară, la un exercițiu mai greu, decît după ce ai dovedit că poti realiza corect(!!) exercițtiile anterioare].
Dar cel mai important obiectiv al acestui mod de a forma viitorii înotători de performanță este faptul ca atît ‘Dozarea încărcăturii’ exercițiilor cît și ‘Gradarea complexității’ lor, exclude ‘Forțarea timpurie’ a principalelor funcțiuni ale organismului [sistemul cardio-respirator] = “te strădui să înoți corect ca un sportiv… dar nu pentru a realiza, cu orice preț, record după record”. Este știut că foarte mulți ‘campioni juvenili', de îndată ce obțin primele medalii ajung rapid să se blazeze și să nu mai dorească a deveni ceea ce se presupunea inițial.
Din acest motiv, eu recomand, ‘metoda concomitentă’ si Organizarea instruirii, în atmosfera sportivă, de întrecere dar pe măsura capacităților limitate pe care le au începătorii.

Fiind vorba despre Organizare ... sunt convins ca aplicand aceasta metoda, afara de acstigul pe plan sportiv se poate observa ca acest management duce la un profit real: mai multi incepatori, mai multi bani... iar proverbul 'timp is money' se adevereste inca odata.
