The purpose of this study was to investigate whether a single 1,350-mg dose of Panax notoginseng (PNG) could enhance aerobic capacity, endurance, and mean blood pressure (MAP) in young adults. We randomly assigned 29 untrained adults, aged 20-35 years, to an experimental (EXP, n = 13) or a control (CON, n = 16) group. For 30 days, the EXP took 1,350 mg per day of PNG capsule and the CON consumed 1,350 mg per day of starch capsule. Measurement variables were taken before and after 30 days of either PNG supplement or placebo. Results show that the EXP improved (p < 0.05) their endurance time by >7 minutes, and lowered (p < 0.05) maximal MAP (from 113 +/- 12 to 109 +/- 14 mm Hg) and Vo(2) at the 24th minute (from 32.5 +/- 8 to 27.6 +/- 8 ml.kg(-1).min(-1)) during endurance cycle exercise. Based on this study, we conclude that 1,350 mg per day PNG supplement for 30 days improved endurance time to exhaustion, and lowered MAP and Vo(2) during endurance exercise.
