[QUOTE="WNC2, post: 7385796, member: 12902"] Fondamentalmente la beta alanina ti rallenta l'insorgenza di acido lattico, molto utile in bici, probabilmente è utile facendo running, direi inutile in palestra soprattutto se non fai serie a cedimento con alte ripetizioni [MEDIA=youtube]7PmkVjWaF_U[/MEDIA] International society of sports nutrition position stand: Beta-Alanine Position statement: The International Society of Sports Nutrition (ISSN) provides an objective and critical review of the mechanisms and use of beta-alanine supplementation. Based on the current available literature, the conclusions of the ISSN are as follows: 1) Four weeks of beta-alanine supplementation (4-6 g daily) significantly augments muscle carnosine concentrations, thereby acting as an intracellular pH buffer; 2) Beta-alanine supplementation currently appears to be safe in healthy populations at recommended doses; 3) The only reported side effect is paraesthesia (tingling), but studies indicate this can be attenuated by using divided lower doses (1.6 g) or using a sustained-release formula; 4) Daily supplementation with 4 to 6 g of beta-alanine for at least 2 to 4 weeks has been shown to improve exercise performance, with more pronounced effects in open end-point tasks/time trials lasting 1 to 4 min in duration; 5) Beta-alanine attenuates neuromuscular fatigue, particularly in older subjects, and preliminary evidence indicates that beta-alanine may improve tactical performance; 6) Combining beta-alanine with other single or multi-ingredient supplements may be advantageous when supplementation of beta-alanine is high enough (4-6 g daily) and long enough (minimum 4 weeks); 7) More research is needed to determine the effects of beta-alanine on strength, endurance performance beyond 25 min in duration, and other health-related benefits associated with carnosine. studio completo: [URL='https://www.youtube.com/redirect?event=video_description&redir_token=QUFFLUhqbW14UUxxVjNTOHFHTno5Z1dzVHhiS25iRnNjUXxBQ3Jtc0ttZ3hRQzRQeS0zdXlydVJRbXJrUmViakt6S2NnQ0sxbEh3Zk9PZWJ4dWZpOTI3RlBzSFlEY3duY01tbkNlVnhlZDQ3M0JVZnZpRl9hbm00SmVRSmNBSGMtZExUSHB4ZkR1Z3ltN3c2bjFWWmhka3FVUQ&q=http%3A%2F%2Fwww.jissn.com%2Fcontent%2F12%2F1%2F30&v=7PmkVjWaF_U']http://www.jissn.com/content/12/1/30[/URL] [/QUOTE]
