[B][U]Potential therapeutic effects of branched-chain amino acids 
supplementation on resistance exercise-based muscle damage in human.[/U][/B]
 
[B][U]Abstract.
[/U][/B]Branched-chain amino acids (BCAA) supplementation has been 
considered  an interesting nutritional strategy to improve skeletal 
muscle protein turnover in several conditions.
In this context, there is evidence that resistance exercise (RE)-derived 
biochemical markers of muscle soreness (creatine kinase (CK), aldolase, 
myoglobin), soreness, and functional strength may be modulated by BCAA 
supplementation in order to favor of muscle adaptation. However, few 
studies
have investigated such effects in well-controlled conditions in humans. 
Therefore, the aim of this short report is to describe the potential 
therapeutic effects of BCAA supplementation on RE-based muscle damage in 
humans.
The main point is that BCAA supplementation may decrease some 
biochemical markers related with muscle soreness but this does not 
necessarily reflect on muscle functionality.
 
 
[B][U]Conclusions and perspectives.
[/U][/B]
 
According to the data presented, BCAA supplementation appears to be an 
interesting nutritional intervention to alleviate RE-induced muscle 
soreness.
Although some studies have found that biochemical markers of muscle 
damage are reduced after BCAA supplementation, it does not reflect 
improved muscle function (at least in short term studies).
Paradoxically, although RE, especially lengthening (eccentric) 
contractions, is associated with muscle injury, they can also provide 
significant protection against future muscle damage and are  robustly 
involved in the hypertrophy process [33].
However, little is known about the conditions that result in the 
protective adaptation involving the repeated bout effect and the role of 
BCAA supplementation in this context.
Thus, future studies should try chronic BCAA supplementation (and even 
other  amino acids) against placebo with the same nitrogen load 
(isonitrogenous supplementation protocol) in order to evaluate the 
possible impact on muscle functionality and relate such effects with 
molecular pathways involved in muscle repair and regeneration.

...eeeh.. che ci hai preso per un forum serio?!?  :-P

 soreness.
 
 
A me pare di ricordare che qualcuno del ng avesse riferito che in 
supplementazione BCAA aveva una significativa diminuzione dei DOMS. E 
probabilmente lo avremo pure preso per il culo! :-D
O forse lo diceva Poliquin.
Sono pigro: che dosaggio hanno usato di BCAA?
Comunque l' occasione mi è cara per augurarti Buone Feste Dav.
Non dirmi che te ne starai rintanato a lavorare in negozio tutto il 
tempo, eh? :-)
ciao!

leggi il pdf è una somma di studi con dosaggi differenti.

buone feste anche a te e a tutto il NG mimmolino compreso
