This research was to investigate the effect of fatigue reduction and heart rate recovery (HRR) according to whole body vibration (WBV). 20 healthy participants were recruited and divided into vibration group (VG) and none vibration group (NVG). VG was group with provided vibration and NVG was group without vibration. They exercised slope gait with 8.5 degree and 4km/h during 30min. They rested on the chair type vibrator during 30min. The vibration consists of 10hz as frequency and 5mm as amplitude. We measured the lactate in the blood and HRR before, immediately after exercise and after rest session. The results showed that lactate level in VG the more decreased at 95.2%. The result of HRR was similar including recovery at 50.67% in VG. The WBV with stimulated vessel in muscle assisted the recovery function by reducing the excess post-exercise oxygen consumption (EPOC) quickly and improving blood circulation. The rest with WBV could provide efficient cool-down exercise for elderly and women without other physical activities after exercise.

This study is an experiment to look into recovering process after maximum anaerobic exercise of career wrestlers and their basic fitness. First, group time results in anaerobic power test did not show meaningful differences between groups in PP, MP, LP field. Second, blood glucose showed meaningful difference in 5-year wrestlers group according to time-wise result (p<.001). Third, time-wise results in blood lactic acid concentration showed meaningful difference all in 5-year, 10-year and 15-year career wrestlers group (p<.001). Fourth, side step and general reaction did not show meaningful differences in all the 3 groups. In conclusion, increase or decrease was seen from and also significant differences were seen from the change of anaerobic power, glucose, lactic acid, concentration, basic physical strength reaction which have influence over athletic performance of players after anaerobic exercise. It was found that 5-year career players group was good at variables of power test and glucose. Reason why recovery capability in connection with degree of fatigue was poor in 15-year career players group seemed to have correlation between career and age.

The purpose of the present study was to examine the effects of iron shot practice volume based on golf skill level on the indices of muscle damage and fatigue in blood. Twenty four golf players were studied under conditions of different golf skill level (beginners, intermediate, expert) and practice volume (100, 200, 300balls). In this study blood CK and LDH were determined to show the level of muscle damage, and blood phosphorus, lactate, and ammonia were measured to see the level of fatigue. Blood creatinine, and IGF- I generally used to see the rate of protein synthesis were also measured. In summary, these results are interpreted to mean that 1) blood fatigue factors, muscle damages, and creatinine levels increased due to a rise in the practice volume of iron shot, 2) those levels decreased due to rise in the golf skill level, 3) blood fators and creatinine recovered quickly after exercise, however muscle damages did not recover even after 24hr, Therefore, both golf skill lev-el and practice volume should be considered to prevent muscle damage and fatigue during practice iron shot.

The purpose of this study was to investigate the effects of complex ergogenic aid supplementation on endurance performance, energy substrate utilization (glucose, FFA) and blood fatigue factors (ammonia, lactate, phosphorous, pH, 5-HT) in endurance exercise. Subjects (male=10) took in complex ergogenic aid (180 ml/day) for 4 weeks and were tested after pre-test. Endurance performance times increased after supplementation compared to before supplementation. However, there was no additional accumulation of the fatigue materials. Thus the complex ergogenic aid supplementation caused the delay of the fatigue material accumulation during endurance exercise.

The purpose of this study is to determine the difference of reduction in lactic acid of blood in the course of time 1)whoa applying the blood cleaning therapy during recovery after anaerobic exercise, 2)when applying the massage during recovery after anaerobic exercise, and 3)while taking a rest during recovery after anaerobic exercise, respectively. The subject of this study consists of 30 men who are divided into three groups such as group 1(n=10) for the blood cleaning therapy, group 2(n=10) for the massage and group 3(n=10) for rest. The blood-gathering was performed over four times ; during rest, immediately after unaerobic exercise, and at 10 and 15 minutes during recovery. The results were summarized as fellows. 1. There was reduction in lactic acid when applying the blood cleaning therapy during recovery after anaerobic exercise. And remarkable differences were shown from immediately after exercise to at 10 and 15 minutes during recovery(p<0.01 and p<0.001, respectively). 2. There was also reduction in lactic acid when applying the massage during recovery after anaerobic exercise. No difference wan shown from immediately after exercise to at 10 minutes during recovery. However a remarkable difference was shown from immediately after exercise to at 15 minutes during recovery(p<0.05). 3. The rest group which took a rest during recovery after anaerobic exercise did not show any difference from immediately after exercise to at 10 and 15 minutes during recovery.

Purpose: PL, creatinine and urine output are biomarkers of the suitability and prognosis of fluid therapy in severe burn patients. The purpose of this study is to evaluate the usefulness of predicting mortality by biomarkers and its change during initial fluid therapy for severe burn patients. Methods: A retrograde review was performed on 733 patients from January 2014 to December 2018 who were admitted as severe burn patients to our burn intensive care unit (BICU). Plasma lactate, serum creatinine and urine output were measured at the time of admission to the BICU and after 48 hours. ABSI score, Hangang score, APACHEII, revised Baux index and TBSA were collected after admission. Results: 733 patients were enrolled. PL was the most useful indicators for predicting mortality in burn patients at the time of admission (AUC: 0.813) and after 48 hours (AUC: 0.698). On the other hand, mortality prediction from initial fluid therapy for 48 hours showed different results. Only creatinine showed statistical differences (P<0.05) in mortality prediction. But there were no statistical differences in mortality prediction with PL and UO (P>0.05). Conclusion: In this study, PL was most useful predictor among biomarkers for predicting mortality. Improvement in creatinine levels during the first 48 hours is associated with improved mortality. Therefore, efforts are needed to improve creatinine levels.

This study selected 10 university football male players and repeatedly treated them as sports massage group, exercise resumption group, and stability resumption. After maximum exercise, when sport massage, exercise resumption, and stability resumption were applied during recovery, blood lactic acid concentration and $LDH_5$ isozyme concentration were examined. Finally this study obtains the following conclusion 1. There was a significant difference in both lactic acid concentration and time between groups. Besides, the cross-action on group and time was significant. 2. There was a significant difference in both $LDH_5$ concentration and time between groups. Besides, the cross-action on group and time was significant. Based on the above findings, this study suggests that sport massage resumption and exercise resumption remove blood lactic acid more quickly than stability resumption to promote recovery. That means that sport massage and exercise resumption anre very effective for lowering the level of fatigue. Thus sport massage or exercise resumption treatment is considered to have a very positive effect on player's quick recovery and it should be used aggressively in a field.

The purpose of this study is to examine the effect of Prunus mume supplementation on changes of energy substrate (glucose, FFA) and fatigue factors (lactate, ammonia, phosphorous) in the performance of exercise. The subjects of this study were 15 male university students. The exercise test was performed for 30 minutes at 75% $VO_2max$ on the treadmill and conducted both before and after administering Prunus mume for 6 weeks. Through Prunus mume supplementation, the accumulation of such fatigue factors as lactate, ammonia, and phosphorous along with concentration of glucuse decreased, but the concentration of FFA increased. From the study, it can be seen that Prunus mume plays a positive role for the use of energy substrates and accumulated fatigue factors.

Effects of wild plant extract (Lak) based on Korea traditional prescription on maximal exercise performance and endurance were evaluated using calorie-restriction animal model. In acute forced swimming test with 10% body weight attached to tail, dietary Lak supplementation increased exercise performance endurance by increasing concentrations of ATP and insulin-like growth factor-1 (IGF-1) under calorie-restriction condition, and decrement of blood lactic acid concentration and increment of muscle ATP content were observed. These results suggest Lak is very effective for decreasing side-effects of obesity therapy using very low calorie diet.
