Badanie numer jeden , badające wpływ 28-dniowej suplementacji HMB/placebo (0g; 3g; 6g HMB/d) na sportowców, pod kątem hamowania/powstrzymywania katabolizmu mięsniowego, wpływu na wzrost beztłuszczowej masy ciała, oraz siły/wytrzymałości w wybranych ćwiczeniach:
Calcium beta-hydroxy-beta-methylbutyrate (HMB) supplementation has been reported to reduce muscle catabolism and promote gains in fat-free mass and strength in subjects initiating training. However, whether HMB supplementation promotes these adaptations in trained athletes is less clear. This study examined the effects of HMB (as the calcium salt) supplementation during resistance training (6.9+/-0.7 hr x wk(-1)) on markers of catabolism, body composition and strength in experienced resistance-trained males. In a double-blind and randomized manner, 40 experienced resistance-trained athletes were matched and assigned to supplement their diet for 28 d with a fortified carbohydrate/protein powder containing either 0, 3 or 6 g x d(-1) of calcium HMB. Fasting venous blood and urine samples, dual energy X-ray absorptiometer-determined body composition, and isotonic bench press and leg press one repetition maximums (1 RM) were determined prior to and following 28 d of supplementation. HMB supplementation resulted in significant increases in serum and urinary HMB concentrations. However, no statistically significant differences were observed in general markers of whole body anabolic/catabolic status, muscle and liver enzyme efflux, fat/bone-free mass, fat mass, percent body fat, or 1 RM strength. Results indicate that 28 d of HMB supplementation (3 to 6 g x d(-1)) during resistance-training does not reduce catabolism or affect training-induced changes in body composition and strength in experienced resistance-trained males.

I ostatnie badanie , badające podobnie jak poprzednie wpływ suplementacji HMB na siłę (wyciskanie na ławie, przysiad, zarzut) i skład ciała futbolistów (35 osob, 16 podawano placebo, 19 - HMB w dawce 3g/d) , poddanych 20 godzinom treningu na tydzień. Badanie trwało 4 tygodnie.
This study assesses the effects of daily beta-hydroxy beta-methylbutyrate (HMB) supplementation on muscular strength (bench press, squats, and power cleans) and body composition (body weight and body fat) among collegiate football players undergoing a strenuous exercise program. Subjects were collegiate football players (n = 35) training under the supervision of certified strength coaches averaging 20 hours of weekly exercise. In the first supplementation period, 16 of the 35 subjects were supplemented with 3 g of HMB per day for 4 weeks; the other 19 received a placebo followed by a 1-week washout period and then a second supplementation period in a randomized double-blind crossover, placebo design. There were no significant changes (p > 0.05) in muscular strength, including bench press, squats, and power cleans, among the subjects. There were also no significant changes (p > 0.05) in body composition, including body fat and body weight. Very little clinical evidence exists for supplementing HMB in athletic populations.
Wyniki: nie zanotowano satysfakcjonujących różnic pomiędzy obiema grupami, tak w wynikach siłowch, jak i w różnicach dotyczących składu ciała. Wnioski oficjalne autorów badań: "Są bardzo nikłe przesłanki ku temu by stosować HMB u sportowców."
