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.
