Summary

This study aimed to conduct a double-blind randomized pragmatic trial to evaluate the effects of off-the-shelf leucine metabolite supplements HMB-FA, HMB-Ca, alfa-HICA, on resistance training-induced changes in body composition, performance and biochemical markers of muscle damage. The investigators' working hypothesis is that so long as subjects adhered to a diet containing adequate energy and dietary protein, there would be no differences between those receiving the leucine metabolites - HMB-FA, HMB-Ca and alfa-HICA - when compared to a placebo consuming group.

Conditions

  • Resistance Training

Interventions

DIETARY_SUPPLEMENT

HMB-FA

One gram of HMB-FA was ingested before exercise, and two grams were ingested at subsequent meals (1 g per meal). At rest days supplement was administered 1 g per meal. The total duration of the intervention was 8 weeks.

DIETARY_SUPPLEMENT

HMB-Ca

One gram of HMB-Ca was ingested before exercise, and two grams were ingested at subsequent meals (1 g per meal). At rest days supplement was administered 1 g per meal. The total duration of the intervention was 8 weeks.

DIETARY_SUPPLEMENT

alfa-HICA

Five hundred miligram of alfa-HICA was ingested before exercise, and one gram was ingested at subsequent meals (500 mg per meal). At rest days supplement was administered 500 mg per meal. The total duration of the intervention was 8 weeks.

OTHER

Placebo comparator

One gram of magnesium stearate was ingested before exercise, and two grams were ingested at subsequent meals (1 g per meal). At rest days placebo was administered 1 g per meal. The total duration of the intervention was 8 weeks.
