BCAAS en volumen

Tras mucho y mucho leer, no he logrado aclarar si este suplemento es beneficioso en etapa de volumen o no.
Por lo general, me suelen comentar que se suelen tomar más que nada en definición.
Por tanto ¿podrías aclararme si merece la pena o no tomarlos estando en volumen?
Y en caso de que la respuesta sea sí ¿que marcas son las que ofrecen una mejor relación calidad-precio?
¿Qué os parecen los 2200 de Dymatize?

4 cápsulas aportarían:
- 10 mg de vitamina C
- 1.7 mg de riboflamina
- 1.5 mg de vitamina B

Leucina 1100 mg
Isoleucina 550 mg
Valina 550 mg

Espero vuestra ayuda, un saludo.
 
No, no es necesario. Con la dieta de volumen, sumado a las tomas de proteina, ya vas de sobra. Los bcaa son mucho mas necesarios en definicion ya que hay que recortar bastante. Los dymatize 2200 los probe y son buenos, y tienen buena reputacion.
 
són necesarios siempre,
pero como comentan con la dieta ya vas servido y si encima estás tomando una proteina(polvo) que trae estos también.....pues más que suficiente.
 
en volumen creo que con la comida no deberias tener problemas en cubrir tus necesidades de Aminoacidos esenciales... ni en definicion creo que tendrias problemas a menos que tengas una dieta muy escasa.
 
Por las respuestas no los tomaré por ahora... y de los que comento al principio ¿qué tal los veis?
Quizás un pelín flojillas las cantidades ¿no?
Por cierto, también había pensado en la glutamina, pero visto lo visto es más de lo mismo...
 
mejor tampoco agas pesas, visto lo visto es lo mismo...

Addition of glutamine to essential amino acids and carbohydrate does not enhance anabolism in young human males following exercise.

We examined the effect of a post-exercise oral carbohydrate (CHO, 1 g.kg(-1).h(-1)) and essential amino acid (EAA, 9.25 g) solution containing glutamine (0.3 g/kg BW; GLN trial) versus an isoenergetic CHO-EAA solution without glutamine (control, CON trial) on muscle glycogen resynthesis and whole-body protein turnover following 90 min of cycling at 65% VO2 peak. Over the course of 3 h of recovery, muscle biopsies were taken to measure glycogen resynthesis and mixed muscle protein synthesis (MPS), by incorporation of [ring-2H5] phenylalanine. Infusion of [1-13C] leucine was used to measure whole-body protein turnover. Exercise resulted in a significant decrease in muscle glycogen (p < 0.05) with similar declines in each trial. Glycogen resynthesis following 3 h of recovery indicated no difference in total accumulation or rate of repletion. Leucine oxidation increased 2.5 fold (p < 0.05) during exercise, returned to resting levels immediately post-exercise,and was again elevated at 3 h post-exercise (p < 0.05). Leucine flux, an index of whole-body protein breakdown rate, was reduced during exercise, but increased to resting levels immediately post-exercise, and was further increased at 3 h post-exercise (p < 0.05), but only during the CON trial. Exercise resulted in a marked suppression of whole-body protein synthesis (50% of rest; p < 0.05), which was restored post-exercise; however, the addition of glutamine did not affect whole-body protein synthesis post-exercise. The rate of MPS was not different between trials. The addition of glutamine to a CHO + EAA beverage had no effect on post-exercise muscle glycogen resynthesis or muscle protein synthesis, but may suppress a rise in whole-body proteolysis during the later stages of recovery.

Effect of glutamine supplementation combined with resistance training in young adults.

The purpose of this study was to assess the effect of oral glutamine supplementation combined with resistance training in young adults. A group of 31 subjects, aged 18-24 years, were randomly allocated to groups (double blind) to receive either glutamine (0.9 g x kg lean tissue mass(-1) x day(-1); n = 17) or a placebo (0.9 g maltodextrin x kg lean tissue mass(-1) x day(-1); n = 14 during 6 weeks of total body resistance training. Exercises were performed for four to five sets of 6-12 repetitions at intensities ranging from 60% to 90% 1 repetition maximum (1 RM). Before and after training, measurements were taken of 1 RM squat and bench press strength, peak knee extension torque (using an isokinetic dynamometer), lean tissue mass (dual energy X-ray absorptiometry) and muscle protein degradation (urinary 3-methylhistidine by high performance liquid chromatography). Repeated measures ANOVA showed that strength, torque, lean tissue mass and 3-methylhistidine increased with training (P < 0.05), with no significant difference between groups. Both groups increased their 1 RM squat by approximately 30% and 1 RM bench press by approximately 14%. The glutamine group showed increases of 6% for knee extension torque, 2% for lean tissue mass and 41% for urinary levels of 3-methylhistidine. The placebo group increased knee extension torque by 5%, lean tissue mass by 1.7% and 3-methylhistidine by 56%. We conclude that glutamine supplementation during resistance training has no significant effect on muscle performance, body composition or muscle protein degradation in young healthy adults.

The effects of high-dose glutamine ingestion on weightlifting performance.


The purpose of this study was to determine if high-dose glutamine ingestion affected weightlifting performance. In a double-blind, placebo-controlled, crossover study, 6 resistance-trained men (mean +/- SE: age, 21.5 +/- 0.3 years; weight, 76.5 +/- 2.8 kg(-1)) performed weightlifting exercises after the ingestion of glutamine or glycine (0.3 g x kg(-1)) mixed with calorie-free fruit juice or placebo (calorie-free fruit juice only). Each subject underwent each of the 3 treatments in a randomized order. One hour after ingestion, subjects performed 4 total sets of exercise to momentary muscular failure (2 sets of leg presses at 200% of body weight, 2 sets of bench presses at 100% of body weight). There were no differences in the average number of maximal repetitions performed in the leg press or bench press exercises among the 3 groups. These data indicate that the short-term ingestion of glutamine does not enhance weightlifting performance in resistance-trained men.

siempre un gusto hablar contigo ronaldinho.

saludos.
 
madre mia, como sigas asi vas a echar ala quiebra a todas las marcas de suplementos, y tomaran medidas contra ti, te estas dando cuenta que estas revolucionando el mundo del culturismo? gestop en lo unico que estamos de acuerdo es en el cafe,,, jajajajaja

la glutamina junto alos bcaa son unos de los aminoacidos mas importantes, no hableis sin saver

__meparto_

por cierto la glutamina es un aminoacido no esencial, por lo que su produccion endogena no deberia de ser un problema (al menos en humanos __meparto_)
 
entonces tu crees que despues de un intenso entreno tu cuerpo producira la suficiente glutamina para cubrir esas necesidades no? ahhhhhhhhhhhh no lo sabia, sigo diciendote lo mismo no me valen lo que digan unas paginas en internet me valen los resultados que saltan ala vista
