- 概要（英）
- Piceatannol is a type of polyphenol that is abundantly obtained from passion fruit. The present study aimed to determine the effect of 7 days of piceatannol supplementation on fat metabolism at rest, during and after low-intensity aerobic exercise. This randomized, double-blind, and crossover study included eight physically active male participants. The participants completed two experimental trials: placebo and piceatannol. They ingested either a placebo or piceatannol tablets containing 0 or 10 mg of piceatannol for seven consecutive days. The participants visited the laboratory at 8:00 am after seven days. In the following baseline measurements, the participants performed 60 min of pedaling exercise at 30% of their maximum oxygen uptake. Respiratory gas and blood samples were collected before, during, and after the exercise. No significant differences were found between the trials in oxygen uptake, carbon dioxide output, ventilation, and respiratory exchange ratio either at rest and during and after exercise. Similarly, serum growth hormone, cortisol, insulin, free fatty acid, glycerol, acetoacetic acid, 3-hydroxybutyric acid, and ketone body responses exhibited no significant differences between trials. These results indicate that the 7-day piceatannol supplementation did not promote fat metabolism at rest and during and after low-intensity aerobic exercise.
