[GLUTAMMINA]Blood Ammonia Concentration
Blood ammonia concentration increases during endurance exercise and has been proposed as a cause for both peripheral and central fatigue. We examined the impact of glutamine and (or) carbohydrate supplementation on ammonemia in high-level runners. Fifteen men in pre-competitive training ran 120 min (approximately 34 km) outdoors on 4 occasions. On the first day, the 15 athletes ran without the use of supplements and blood samples were taken every 30 min. After that, each day for 4 d before the next 3 exercise trials, we supplemented the athletes' normal diets in bolus with carbohydrate (1 g.kg(-1).d(-1)), glutamine (70 mg.kg(-1).d(-1)), or a combination of both in a double-blind study. Blood ammonia level was determined before the run and every 30 min during the run. During the control trial ammonia increased progressively to approximately 70% above rest concentration. Following supplementation, independent of treatment, ammonia was not different (p>0.05) for the first 60 min, but for the second hour it was lower than in the control (p<0.05). Supplementation in high-level, endurance athletes reduced the accumulation of blood ammonia during prolonged, strenuous exercise in a field situation.

Matteo scrivo qui e poi cancello perchè ho disabilitato i PVT. Bravo!benissimo, ma quando riporti studi devi darmi le references precise come ho fatto io in quelli che ho postato. Li sto leggendo piano piano e quelli meritevoli li approvo, ma tu dammi le references così le aggiungo please

marco ..caxxo...ho gli studi ma le reference non le copiai...al tempo.
Comunque li ho presi su Pubmed...posso ricercarli appena ho un attimo e si aggiungono ok?
