Abstract

We investigated whether creatine (CR) and beta-hydroxy-beta-methylbutyrate (HMB) act by similar or different mechanisms to increase lean body mass (LBM) and strength in humans undergoing progressive resistance-exercise training. In this double-blind, 3-wk study, subjects (n = 40) were randomized to placebo (PL; n = 10), CR (20.0 g of CR/d for 7 d followed by 10.0 g of CR/d for 14 d; n = 11), HMB (3.0 g of HMB/d; n = 9), or CR-and-HMB (CR/HMB; n = 10) treatment groups. Over 3 wk, all subjects gained LBM, which was assessed by bioelectrical impedance analysis. The CR, HMB and CR/HMB groups gained 0.92, 0.39, and 1.54 kg of LBM, respectively, over the placebo group, with a significant effect with CR supplementation (main effect P = 0.05) and a trend with HMB supplementation (main effect P = 0.08). These effects were additive because there was no interaction between CR and HMB (CR x HMB main effect P = 0.73). Across all exercises, HMB, CR, and CR/HMB supplementation caused accumulative strength increases of 37.5, 39.1, and 51.9 kg, respectively, above the placebo group. The exercise-induced rise in serum creatine phosphokinase was markedly suppressed with HMB supplementation (main effect P = 0.01). However, CR supplementation antagonized the HMB effects on serum creatine phosphokinase (CR x HMB interactive effect P = 0.04). Urine urea nitrogen and plasma urea were not affected by CR supplementation, but both decreased with HMB supplementation (HMB effect P < 0.05), suggesting a nitrogen-sparing effect. In summary, CR and HMB can increase LBM and strength, and the effects are additive. Although not definitive, these results suggest that CR and HMB act by different mechanisms.

  • In general, creatine and beta-hydroxy-beta-methylbutyrate have positive effects on lean body mass and strength, but the effects tend to be small and are not consistent.

    “In general, these agents have positive effects on lean body mass and strength, but the effects tend to be small and are not consistent.”
  • Co-ingesting creatine monohydrate with HMB, beta-alanine, phosphates, or alpha-lipoic acid may have some additive effects.

    “Several studies have also indicated that co-ingesting CM with other potentially ergogenic nutrients such as beta-hydroxy-beta-methylbutyrate (HMB) (Jowko et al. 2001), beta-alanine (Hoffman et al. 2006), phosphates (Eckerson et al. 2005), and alpha-lipoic acid (Burke et al. 2003b) may have some additive effects.”
  • Creatine supplementation has been demonstrated to potentiate muscle hypertrophy, strength, and muscle fiber cross-sectional area growth in response to resistance training.

    “Creatine supplementation has also been demonstrated to potentiate muscle hypertrophy, strength, and muscle fiber cross-sectional area growth in response to resistance training [166,167].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
