PEREZ, Diego Ignácio Valenzuela et al. Acute Ginger extract supplementation no increase the metabolism at the rest and during exercise. Motri. [online]. 2020, vol.16, suppl.1, pp.38-45.  Epub 29-Jan-2021. ISSN 1646-107X.  https://doi.org/10.6063/motricidade.22256.

This study evaluated the acute effect of ginger (Zingiber officinale) supplementation (3.0 g) on metabolism. For this, 12-male physically active college were measured (22.8±3.3 yrs.; 79.4±12.5 kg; 1.8±0.1 m; 25.4±3.0 kg/m2; 16.9±3.1 %BF). Three-hours after supplementation (ginger or placebo) (Baseline - lasting 30-min) the resting metabolic rate (RMR), oxygen uptake (VO2), carbon dioxide production (VCO2), respiratory quotient (RQ) protein (PRO), carbohydrate (CHO), and fat oxidation were measured. All participants then performed 30-min of aerobic exercise (75-85 % of reserve heart rate - RHR). Finally, the same post-exercise variables for 60-min were measured. For the measures performed at rest and after exercise were observed effect of the moment of measurement, where the measures obtained at post-exercise 1 exercise (0-30 min) were significative higher (p≤0.001 for RMR; VO2; VCO2; PRO and CHO; p=0.001 for RQ; p=0.03 for FAT) in comparison to rest and post-exercise 2 (30-60 min) moments. Similar results were observed at the exercise for VO2 (31.5±3.1 vs. 31.9±3.7 mL/kg/min; p=0.78) and ventilatory equivalents for oxygen (VE/VO2: 24.1±2.5 vs. 24.4±3.3; p=0.75) where no differences were observed between conditions. In conclusion, for the applied protocol, acute ginger extract supplementation produced no metabolic ergogenic effect.
