Beta-hydroxy-beta-methylbutyrate Ingestion, Part I: Effects On Strength And Fat Free Mass

Effect None
Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 37
Gender Male
Age Range 18-29
Body Types Untrained, Average
Notes for this study:
38mg/kg HMB supplementation (approximately 3g daily) and double that dose were given to untrained persons alongside a resistance training program for 8 weeks. Peak isometric and isokinetic torque was (sporadically) higher in HMB supplemented groups relative to placebo while the 1 rep max testing failed to show significant differences (trended towards an increase), only the 38mg/kg group exhibited increases in lean mass.

Effects Of Beta-hydroxy Beta-methylbutyrate On Power Performance And Indices Of Muscle Damage And Stress During High-intensity Training

Effect None
Trial Design Double blind
Trial Length 1-2 Weeks
Number of Subjects 26
Gender Male
Age Range 18-29
Body Types Trained, Overweight, Average
Notes for this study:
3g HMB given to collegiate athletes for 10 days during training camp failed to influence any measured hormonal, muscular, or performance parameter under investigation. Both soreness and perception of practise intensity were not significantly affected.

β-Hydroxy-β-methylbutyrate Free Acid Reduces Markers Of Exercise-induced Muscle Damage And Improves Recovery In Resistance-trained Men

Effect None
Trial Design Double blind
Trial Length 24 hours
Number of Subjects 20
Gender Male
Age Range 18-29
Body Types Trained, Average
Notes for this study:
3g of HMB as free acid (1g taken 30 minutes prior to exercise, two 1g servings taken 30 minutes prior to lunch and dinner) over the course of one training day was able to increase the rate of muscular recovery (percieved) and reduce creatine kinase in serum relative to placebo; no other parameter was affected
