| seconds at which the maximum anaerobic power was recorded. Following the initial assessment, each subject was administered 800 mg of ciwujia (ENDUROX TM) daily for two weeks. They returned to the exercise physiology laboratory for a repeat of the aerobic and anaerobic assessments. |
| After the administration of ciwujia there was a decrease in lactic acid levels which became more pronounced at higher energy loads. At higher workloads, for example, 150 to 180 watts, the decrease in lactic acid levels, when compared to the control group, ranged from 31 percent to 33 percent. |
| During exercise, carbohydrate and fat represent the primary sources of energy. A decline in the respiratory quotient (RQ) indicates that relatively less energy is produced by carbohydrate metabolism and more from fat metabolism. Following administration of ciwujia, there was a significant drop in the RQ at various energy loads. A decrease in RQ can be translated into a percentage increase in fat metabolism. |
| Mean increase in fat utilization in the ciwujia group over the study group was 43.2 percent. These results indicate that ciwujia offers significant advantages during exercise. By shifting the energy source from carbohydrate to fat during exercise, ciwujia increases fat metabolism and delays the buildup of lactic acid. |
| The anaerobic threshold was computed by plotting lactic acid levels versus power load for each group. The ciwujia group demonstrated a 12.4 percent increase in the anaerobic threshold over the control group. |
| To better understand the effect of ciwujia on exercise of longer duration, several studies have recently been conducted in the exercise physiology laboratory at the University of North Texas Health Science Center, under the direction of Robert Kaman, Ph.D. In one trial, ten males underwent aerobic measurements using a bicycle ergometer. Subjects pedaled a light workload of 100 watts at a rotational speed of 60 rpms for 60 minutes. Heart rate, oxygen, CO 2, and RQ were measured every four minutes. The subjects were then administered 800 mg of ciwujia daily for ten days and then returned to the laboratory for a second aerobic assessment. |
| The mean drop in RQ is 0.09, which translates into a 30 percent increase in fat metabolism during the hour of cycling. |
