The purpose of this study is to observe the effects of pine needles powder intake and athletic training on the energy metabolic substrates. To achieve this purpose, 42 Sprague-Dawley male rats were selected to feed pine needles powder and swimming exercise for 5 weeks. There was no significant difference in the weight increase rate while intaking pine needles powder and exercising at the same time. Compared to the swimming exercise group, high cholesterol diet group and high cholesterol diet+swimming exercise group, the pine needles powder intaking group and pine needles powder intake+swimming exercise group suppressed AMPK expression, significantly. Thus, for the result of GLUT-2 and GLUT-4 which are the glucose transporter of liver and skeletal muscle, the pine needles powder intaking group and pine needles powder intake+swimming exercise group showed significantly higher expression. For the glycogen content of liver and muscle, the pine needles powder intaking group and pine needles powder intake+swimming exercise group increased significantly. Therefore, the findings of this study would be used as the basal data of exercise nutrient supplements as the pine needles powder intake gives positive effect on the energy storage capacity.

The purpose of this study was to investigate the potential of persimmon vinegar as a functional beverage by analyzing the effects of persimmon vinegar ingestion on the energy substrate during endurance exercise. The healthy male adolescents (n=8) drunk persimmon vinegar ingested trial (PSV) or purified water ingested trial as the control trial (CON) 1 h prior to the exercise with the 60% of maximal oxygen uptake (VO_₂max) for 1 h. The exercise intensity was increased to the 80% of VO₂_max and remained until exhaustion. And the physiological variables blood components and amounts of energy oxidation were analyzed. There was no significant difference between trials in physiological variables and the heart rates after exhaustion were higher in PSV compared to CON. There was no significant difference between trials in blood glucose level while the blood lactic acids decreased significantly in PSV 30 and 60 minutes after onset of exercise. The free fatty acids concentration increased significantly in PSV from 15 minutes to 60 minutes after onset of exercise. The carbohydrate oxidation decreased significantly in PSV from 45 minutes after exercise and on the contrary the fatty acids oxidation increased significantly for the same period. And fatty acids oxidation was higher in PSV compared to C|ON even after exhaustion. The respiratory exchange ratio was lower significantly in PSV compared to CON from 30 minutes to 60 minutes after exercise whereas lower in CON after total exhaustion. The exercise time to exhaustion was 41% longer in PSV compared to CON. These results showed that the persimmon vinegar increase the level of lipids metabolism and decrease sense of fatigue by inhibiting carbohydrate oxidation during moderate intensity exercise suggesting the possibility of using of persimmon vinegar as exercise functional beverage when ingested 1 h prior to the endurance exercise performance.

The purpose of this study was to investigate the anti-apoptosis-related protein expression in skeletal muscle of rats with different amount of mountain ginseng (MG) added high-fat diet fed. Twenty-four Sprague Dawley male rats were divided into the high-fat diet control group (CON), 0.5% of MG added diet group (MG1), and 1.0% of MG added diet group (MG2) with eight rats each. The P53, anti-apoptotic protein, was significantly lower in MG2 than CON and MG1. The bcl-2 and bcl-xl, however, were not significantly different from MG1 but from CON. The caspase-9 and -3, were significantly lower in MG groups than CON. In addition, it was dramatically lower in MG2. These results suggested that MG addition to the high-fat diet suppressed p53 protein expression and enhanced anti-apoptototic protein expression. MG may be a positive effects on health as a medicinal plant.
