N/A To purpose of this study was to examine the effect of (-)-hydroxycitrate (HCA) ingestion on expired gas metabolism during endurance exercise as an ergogenic aid. For the propose, six college soccer players participated and were individually asked to take the different amount of HCA(250㎎, 7550㎎, and placebo) for five days. One hour after ingestion of the HCA, expired gas was analyzed at rest and during endurance exercise. The major findings were as follows; 1. The change of VO2 was not significantly different among the three trials; 2. The HCA trials were slightly less RER than the control trial but it was not significantly different; 3. The HCA trials were less in CHO oxidation than the control trial but it was not significantly different; 4. The HCA trials showed slightly higher fat oxidation than the control trial but it was not significantly different; 5. The exercise time to exhaustion was 66.02min for the control trial, 69.43min for the 250㎎ HCA trial, and 70.94min for the 750㎎ HCA trial. In summary, different amount of HCA ingestion for five days was not statistically affected on expired gas metabolism. As shown in RER and fat oxidation, however, it was slightly lower or higher during exercise at 60% VO2max and 80% VO2max exercise compared to control trial. Therefore, HCA ingestion 1h prior to exercise have the effect of ergogenic aid during endurance exercise in athletes.
