Doua mari probleme....

1 Decembrie....:

"La multi ani Patrie draga !"
====================
...... In sportul mondial se contureaza 2 probleme mari, situate la extreme: sportul ca debut si prestatia sportiva de top.

In ceea ce priveste 'debutu' sunt controverse rezultate din Organizare si motivatiile generate de aceasta.... la extrema cealalta, la cap. Pregatire, nu mai sunt prea mari probleme dar ramane un cap. plin de mister si incertitudini: "sustinerea si refacerea dupa efort" pentru a supracompensa organismul ce se vrea in top [ in acest domeniu noi am avut un reprezentat stralucit, pe Prof. Dr. Ioan Dragan, FINA-Medical Com/Dep. anti-doping, omagiat in doua randuri de acest inalt for international cu argint si aur, asa cum se obisnuieste la sportivi ...., D-zeu Sa-l odihneasca].

Aici exista si empirism, traditii si sfaturi 'babesti' dar si multa cercetare stiintifica, de regula chiar foarte secreta !

In acest 'bol' de cunoastere, tin sa remarc deschiderea, aproape genetica a specialistilor de origine slava [ei 'spun' tot...] spre deosebire de ceilalti [in care exista si exceptii , ca cel de mai jos ....]

Este greu sa faci performanta reusita ? Este un mirocol sa obtii 2 medalii de aur la o singura editie JO si apoi sa 'clachezi' aproape inremedibil [ la CES Eindhoven , nu am avut nici o participare...] ?

Sportul de performanta are nevoie de meseriasi profesionisti, total dedicati si nu de politrugi !

Inotul sa faca abstractie de politrugi, sa-i ignore dar sa-i 'infranga' prin rezultate incontestabile care sa nu poate fi apreciate decat OBIECTIV
!

"Happy Birthday dear motherland!"
====================
...... In the sports world two issues looming large, situated at the extreme: the Beginning and the sport's top sports performance.

Regarding the 'beginning' is controversy arising from this organization and motivation .... At the other extreme, to the head. Training, there are great problems but remains a chapter full of mystery and uncertainty "and support the recovery effort" over-compensate for what the body wants the top [in this area we had a brilliantly represented, Prof. Dr. Ioan Dragan, FINA-Medical Com / Dep. Anti-Doping honored in two rows of this international organization with high silver and gold, as is customary in athletes ...., God rest him].

Here there and empiricism, traditions and advice 'Babesia' but more scientific research, usually very, verry secret!

In this 'bowl' of knowledge, I must mention the opening of Slavic specialists, almost genetics [they 'say' anything from them learn more ...] unlike the others [where there are exceptions, like the one below ....]

It is hard to make successful performance? It is a miracle to get two gold medals at a single edition of OJ and then not be able to do so, almost inremedibil [CES Eindhoven, we have not had any participation ...]?

Sport performance needs of professional tradesmen, totally committed and not politrugs!

Swimming to ignore the politrugs, but to ignore her 'defeat' by compelling results that can not be assessed only object with the timer!

Creatine: the secret behind boosting muscle

Merhaba folks!

There’s absolutely no question that one of the most interesting and complex fields in sports science is that of sports nutrition. There’s a lot of absolute nonsense spouted by irresponsible people, particularly on the internet, all with the aim of selling pills. Many of these pills are about as useful as taking tic tacs and in some cases they can be harmful. The sports nutrition industry is enormous and there are plenty of products promising huge gains in muscle mass and sporting performance without have to lift a weight.

I thought therefore that I’d just talk briefly about the two supplements for which there is the most scientific rationale (outside carbohydrates and protein). They are creatine and beta-alanine (BA).

"The main effect of both creatine and BA is that they enable you to complete more work, which in turn makes you stronger. But remember, they won’t make you stronger on their own!"

Creatine is perhaps the most effective ergogenic (performance enhancing) nutritional supplement currently available to athletes in terms of their ability to sustain high-intensity exercise and in improving lean body mass during training. It is particular relevant to sports such as rugby, rowing and field athletics and has been shown to increase maximal strength values in resistance-trained athletes.

There have been a couple of proposed reasons for this improvement in muscular performance. By increasing bodily reserves of creatine, supplementation is thought to:

  • enhance the phosphagen energy system’s ability to provide ATP (the body’s energy currency) to the working muscles, thus allowing an increased capacity to continue training ;
  • enhance protein synthesis; and
  • may increase muscle fibre growth if combined with the appropriate resistance training programme.

Additionally, creatine monohydrate has been shown to enhance the effects of a protein-carbohydrate mix. Most studies on creatine have advocated a ‘loading phase’ at the beginning of creatine supplementation. This comprises of approximately 5g taken 4 times per day for about 1 week followed by 3-5g/day thereafter. This has been shown to increase muscle creatine and phosphocreatine stores by anywhere between 10-40% although further research needs to be conducted to determine if this supplementation protocol needs to be ‘cycled’ (a process of returning to a loading phase for 3-5 days every 3-4 weeks and then a washout period).

Beta-alanine (BA)

BA has been shown to be effective in increasing intramuscular carnosine concentrations. Carnosine is an important muscle buffer during high intensity exercise which may be vital in delaying neuromuscular fatigue and has been shown to help increase training volumes and lower subjective feelings of fatigue in American Footballers performing a series of anaerobic performance measures. In English, this means that it ‘neutralises’ the acid build up in muscles (the burning feeling that makes us reduce our exercise intensity).

Additionally, BA has been shown to produce positive performance effects when combined with creatine supplementation. Whilst the optimal dosage of BA is still yet to be determined, positive results from previous research suggests between 4.5 and 6g per day.

In short, the main effect of both creatine and BA is that they enable you to complete more work, which in turn makes you stronger. But remember, they won’t make you stronger on their own!

Next time I thought I’d write about how to build powerful getaway sticks. If you don’t know what getaway sticks are at the moment, you will this time next week.


Until then, stay robust, amigos!

New research suggests that there’s less evidence for adding protein to carbohydrate than many would have us believe.
