שאלה על beta-alanine

[barakav]

הא והיא מעוררת את מערכת העצבים, אז יכול להיות שתיהיה לה יותר השפעה על אימוני כוח ביחד עם ממריצים או תוספים אחרים.

אה וסוף סוף מצאתי את המחקר, היא לא כלכך משפיעה בפני עצמה, אבל היא מחזקת מאוד את ההשפעה של הקריאטין על כוח ושמירה על מסה רזה:

The effects of creatine and creatine plus beta-alanine on strength, power, body composition, and endocrine changes were examined during a 10-wk resistance training program in collegiate football players. Thirty-three male subjects were randomly assigned to either a placebo (P), creatine (C), or creatine plus beta-alanine (CA) group. During each testing session subjects were assessed for strength (maximum bench press and squat), power (Wingate anaerobic power test, 20-jump test), and body composition. Resting blood samples were analyzed for total testosterone, cortisol, growth hormone, IGF-1, and sex hormone binding globulin. Changes in lean body mass and percent body fat were greater (P < 0.05) in CA compared to C or P. Significantly greater strength improvements were seen in CA and C compared to P. Resting testosterone concentrations were elevated in C, however, no other significant endocrine changes were noted. Results of this study demonstrate the efficacy of creatine and creatine plus beta-alanine on strength performance. Creatine plus beta-alanine supplementation appeared to have the greatest effect on lean tue accruement and body fat composition

סבבה, תודה רבה.
נשמע אחלה דבר, והוא גם יחסית זול ממה שבדקתי...
ניתן לזה ניסיון כשאני אחזור למסה.
