What the analyses of these data revealed was quite conclusive: The provision of "regular" calcium HMB at a dosage of "only" 3g/day had a highly significant "advantageous effecton the increase in aerobic capacity and the reduction of fat mass" (Durkalec-Michalsky. 2015). More specifically,...
* the subjects' VO2 max increased (+2.7 mL/min/kg) significantly (p < 0.001) in comparison to PLA where it was even slightly reduced (−1.0 mL/min/kg),
* the ventilatory threshold, the threshold load, and the heart rate, which are the time-point, wattage, and heart rate at which further increases in respiration will no longer lead to increases in VO2 intake, were postponed by +1.2 min, +0.42 W, and +9bpm, respectively
* with -0.9 kg the subjects in the HMB group lost body fat, while the subjects in the PLA groups gained 0.8 kg (p = 0.03)
* the refusal time to continue (a proxy of short term recovery) in the progressive test was extended (p = 0.04), maximum load (p = 0.04) and anaerobic peak power (p = 0.02) increased.
