This study investigated effects of regular exercise and F1, 6DP supplement on endurance exercise capacity and antioxidant capacity in rats. Male Sprague-Dawley rats were randomly assigned to one eight groups(n=8): sedentary control group, exercied control group, F1, 6DP supplemented group and exercised F1, 6DP supplement group. F1, 6DP supplemented group, and exercsied F1, 6DP supplement group. Rats were fed experimental diets supplemented with F1, 6DP at the level of 10 ㎎/㎏/day for 4 weeks. Rats of exercised control group, F16-DP supplemented group and exercised F1, 6DP supplement exercised groups performed swimming exercise training at 60 min/day for 4 weeks. Exhaustive swimming time(endurance exercise capacity) was significantly increased in exercised control group, F1, 6DP supplemented group, and exercised F1, 6DP supplement group compared to the value for sedentary control group. Total antioxidant capacity was significantly higher in exercised control group, F1, 6DP supplemented group, and exercised F1, 6DP supplement group than sedentary control group. Free radical release was significantly lower in exercised control group FI, 6DP supplemented group, and exercised F1, 6DP supplement group than sedentary control group, These results indicate that F1, 6DP appear to be effective in enhancing enduranced exercised performance and antioxidant capacity of trained rats.

The purpose of this study was to examine the effects of catechin supplement on fat oxidation, free fatty acids (FFA) and triglyceride (TG) following two different treatments (placebo [PL] and catechin [CT])). Seven healthy male collegiate students participated as subjects after signing an informed consent. The submaximal exercise intensity of this study was the maximal fat oxidation exercise intensity (MFOEI) of subjects. To comparative analysis on the effect of lipid metabolism after exercise (300 kcal) after short-term supplement of catechin for three days it was compared the respiratory exchange ratio(RER), fat kilocalories (Fkcal), FFA and TG following every treatment methods. First, there were not significant differences in fat oxidation included RER and Fkcal among treatment methods. However, the RER values was decreased in the CT and the Fkcal values was increased in the CT than PL. Second, there were significant differences in FFA and TG among treatment methods(p<.05). The TG of CT was significantly higher than PL at 10min of recovery. The FFA concentration of CT was significantly higher than PL at 30 min of recovery. Especially, CT treatment has high than PL for recovery periods. In summary, results of this study revealed that catechin have the beneficial effects on fat oxidation and glycogen sparing by fat metabolism facilitation. Although the detailed molecular mechanism by which catechin enhances fat use during exercise remains to be elucidated, activation of lipid metabolism in skeletal muscle is believed to be a key factor.

This study proposes a structural design method for the upper control arm installed at the rear side of a SUV. The weight of control arm can be reduced by applying the design. In this research, the former includes optimization technology, and the latter the technologies for selecting aluminum as a steel-substitute material. Strength assessment is the most important design criterion in the structural design of a control arm. At the proto design stage of a new control arm, FE (finite element) analysis is often utilized to predict its strength. In this study, the kriging interpolation method is adopted to obtain the minimum weight satisfying the strength constraint and durability criteria. The optimum results determined from the in-house program are compared with those of ANSYS WORKBENCH. The durability assessment is obtained by a index of fatigue durability and trial & error method, MSC. Fatigue program.

The purpose of this study was to compared the fat oxidation after exercise following resistance exercise(1-RM of 60%) and aerobic exercise(VO₂max of 60%). The subjects of study were consisted of ten untrained male college students(19.3±0.5 years). This study was designed to compare the fat oxidation after exercise following two exercise types. For both exercise types, resistance and aerobic exercise was energy consumption of total 300㎉ during exercise(aerobic exercise; 298.6±2.9㎉, resistance exercise; 297.8±2.1㎉). The dependant variables in this study consisted of four parts, metabolic variables(VO₂, RER), EPOC, total energy consumption and fat oxidation after exercise. To compare the difference of metabolic variables rest and recovery period, 2×8 repeated measure two-way ANOVA was used. EPOC, total energy consumption and fat oxidation during recovery period was used t-test. The statistical significance was set at 0.05. The results were obtained as following, first, VO₂ during recovery was higher significantly than the rest(until 5min, p<.05). RER was significantly decreased after resistance exercise(p<.05). Second, result of EPOC and total energy consumption was higher significantly after aerobic exercise(p<.05). The results suggest that EPOC has aerobic exercise higher compared with the resistance exercise, thus exercise prescription for weight loss and fat oxidation following exercise include aerobic exercise. However resistance exercise is recommended, because fat oxidation ratio was higher during recovery period by resistance exercise.

The puppse of this study is to investigate the effects of aerobics exercise on blood lipid factors(TC, TG, HDL-C, LDL-C) and bone mineral density(spine and femoral), and to provide and maintain this information for aerobics exercise. In order to measure the change of blood lipid factors and bone mineral density by aerobics exercise in the elderly women for 4weeks(4 times/week, 60min/day), the subjects are ten. The statistical analysis of the results is carried out paired sample t-test. The results were as follows: 1. The total cholesterol and LDL-C after aerobics exercise has not significant difference(p>.05). 2. The TG and HDL-C after aerobics exercise has significant difference(p<.05). 3. The spine and femoral bone mineral density after aerobics exercise has significant difference(p<.05). These results suggest that this aerobics exercise can improve the change ability of TG, HDL-C and bone mineral density.

This study when to examine the effects of sodium bicarbonate ingestion on metabolicl variables when people are at easy, when they finished the exercise and when they are recovered. The effect on exercise duration during graded exercise was examined as well. Eight male undergraduate students from Department of Physical Education participated in this study as subject. For this purpose, placebo and NaHCO3 treatment, independent variables, were assigned to the controlling group and the experimental group each. Then physiological variables and the exercise continuer time, dependent variables, were analyzed. Through the experiment and statistical methodology, results were found as follow: First, VO2 has no significant difference between controlling and experimental group. However, in both groups, there was significant difference in VO2 according to the participants' status; whether they were at ease, finished the exercise and was resting. Especially in the experimental group, there were differences in VO2 when they finished the exercise and when they were in the status of recovery at an interval of every five minutes from 5 to 15. RER in the experimental group were significantly high when they just finished the exercise and when they were in 5, 10, and 15 minutes of recovery compare to the controlling group. RER were different from every time when measured except when 15 minute have passed since the recovery in controlling group and when 15 minute have passed in experimental group. There were significant differences in the concentration of lactic acid between the two groups. For example, in experimental group, Lactic Acid was low when the subjects were at ease and after 3, 5 and 10 minutes' of resting. In addition, when compared to the status of ease, there were significant differences in the concentration of Lactic Acid after the exercise and 3, 5 and 10 minutes' of recovery. Second,, it is revealed that VO₂max has no significant differences between the two groups. However, it was measured slightly higher in experimental group (58.45㎖/min/㎏) than controlling group (57.36 ㎖/min/㎏). VT level has no significant difference between the two groups. However, it was measured somewhat higher in experimental group (47.1387㎖ /min/kg) than controlling group (41.9250㎖/min/㎏). Exercise duration was significantly different from the two groups. From VT to the end of the exercise, the duration of exercise was 209 seconds (3 minutes and 29 seconds) in experimental group, whereas it was 190 seconds (3 minutes and 10 seconds)in controlling group, which means there was 19 seconds of difference between the two groups. To sum, VO₂ and VT were measured somewhat higher in experimental group compare to controlling group; however, they were not significant. In the matter of RER, it was measured significantly higher in experimental group, while the concentration of Lactic Acid was measured significantly low in experimental group compare to controlling group. In addition, exercise duration was longer in experimental group than controlling group. These results verify that, during the graded exercise, NaHCO3 causes the increase of NaHCO3, and it strengthens the ability of shock-absorbing. On the ground of this research, the future study should be improved in the matters of the subject number, systematic design for the experiment and diverse treatments of variables in order to reveal the effects of NaHCO3 in graded exercise clearly.
