Serum leptin, glucose, lipid profiles (free fatty acid, triglyceride, total cholesterol) were determined in two groups of subjects undergoing long and short strenous cycle race, 8 men who fasted overnight and then pedaled 20km cycle race and 8 men, 150km cycle race, respectively, Blood samples were collected before race, immediately after cessation of race and 2hr, 6hr after the end of race period. Cyclist pedaling 20km cycle race and cyclist pedaling 150km cycle race showed no statistical differences in leptin level. After 6hr of rest, leptin concentrations were gradually decreased but showed no statistical different in both groups. Epinephrine (p〈.01) and norepinephrine (p〈.001) concentration in comparison to pre-race levels were increased significantly. But insulin concentration in comparison to pre-race levels were decreased significantly (p〈.001). Glucose (p〈.01), free fatty acid (p〈.001), cholesterol (p〈.001) and triglyceride (p〈.01) were increased immediately after cessation of race in both groups.

The Purpose of this study was to investigate the effects of fatty diets on blood components. This study employed 14 cycling players who were 20∼21 years old(mean age 20.5years). The subjects were randomly assigned to one of two groups(on group for fatty diet 15% and the other group for fatty diet 30%). The statistically analyzed results of hematological and biochemical components related to pre and post training with various rate of fatty diets(15%, 30%) during 16 days were summarized as follows: 1. Each of caloric expenditure from two groups with 15% and 30% fatty diets demonstrated 3288±177.0kcal and 3563±130.0kcal but no statistical differences in heart rate and body weight between two groups. 2. The level of glucose for 30% fatty diet group and except for TG, the NEFA, Cholesterol, HDL-C, PL, LA, LDH or Mg means between two groups did not show statistically significant differences, 3. Both groups who exercise the same procedure of training increased their body weight approximately 800g after they had been intaked with 15% fatty and 30% fatty diet for 15days. 4. Both groups showed the same values(scores) of hematological and biochemical blood components and fatty acid composition in plasma lipids before and after experimental diets (15% of total energy and 30% of total energy and training). 5. The values of NEFA in the group of 30% of fat diet were statistically higher than those in the group of 15% fat diet during exercise(p<0.05) but in the procedss of exercise time, two groups revealed significantly different values of TG, NEFA, TC, HDL-C, TC, HDL-C, except for PL. 6. The values of glucose in both groups showed no significant differences among experimental diets and during exercise the values of LDH only in the 30% fat group were significantly high due to difference between diets the values of LA, LDH and Mg demonstrated significant difference in process of exercises time.

This study was purposed to investigate the effect of yukmijihwangtang on rat blood components and organ histopathologic changes in the different environments of hyperbaric ambient air. The pharmacological effects of yukmijiwhangtang in oriental medicine have been reported to improve general condition and treat mental and physical weakness due to overload. 84 Male Sparague-Dawely rats, 200-250 g weight, were housed two per cage, fed Standard Rodent Diet with water ad libitum. The animals were assigned to 3 main groups for the blood components and gas analysis : normobaric control group (NC ; N=4), hyperbaric control group (HC ; N=8), hyperbaric medication group (HM ; N=8). HC and HM group were devided into 2 subgroups and kept on different situation of the hyperbaric ambient air (2ATA or 3ATA) for 2 hrs. HM group was administered 10cc extract of boiled yukmijiwhangtang before exposure. For histopathological analysis, hyperbaric groups(HC and HM : N=80) was further devided into 2 subgroups according to atmosphere absolute and exposure period : 2ATA (acute, 1, 2, 3, 4 wks), 3ATA (acute, 1, 2, 3, 4 wks). There were 20 groups in total, with 4 animals in each group. Experimental rats of HM group were administered 10cc extract of boiled yukmijiwhangtang 2 times per day and kept on situation of the hyperbaric ambient air (2ATA and 3ATA) 2 hrs per day for four weeks. In order to record the possible effects of yukmijiwhangtang in hyperbaric condition on the blood components, the rats were killed by decapitation directly after the hyperbaric exposure for 2 hrs. But the administered rats were killed on the morning following the last hyperbaric exposure during 4 wks. The samples were taken 2 hrs, 1, 2, 3, 4 wks after the begining of this study. Blood was collected from posterior abdominal vena cava immediately after decapitation. Organs for histopathological assays in hyperbaric groups (HC and HM) were also removed 2 hrs, 1, 2, 3, 4 wks and fixed at 10% formalin solution. The whole blood of 1㎖ was used for the analysis of pH, PO₂, PCO₂, HCO₃, BE, O₂CT, O₂SAT level by Blood Gas Autoanalyzer (Coning 175, U.S.A). And The rest whole blood of 1㎖ was utilized for the measurement of WBC (white blood cell), RBC (red blood cell), Hb (hemoglobin), Hct (hematocrit), MCV (mean corpuscular volume), MCH (mean corpuscular hemoglobin) level by Microcell Counter (Model; CC-170-TDA Co., Japan). Hematological and blood gas analysis and organ histopathological changes after exposure to hyperbaric ambient air were as follow; (1) Hematological parameters were lower in the hyperbaric medication group than all the control groups without WBC, MCV (2ATA) and MCV, MCH (3ATA). But a statistical significance among the groups was not shown. (2) The hyperbaric medication group was lower than another control groups on all parameters of blood gas analysis after 2 hours exposure to hyperbaric ambient air (2ATA and 3ATA) without O₂SAT. But a statistical significance among the groups was not shown. (3) On observing the histopathological system of the lung with microscope, the congestion, edema and hemorrhage on the alveolar sacs and alveolar wall damage in the hyperbaric control group were heavier than in the hyperbaric medication group.

This experimental study was conducted to examine the effects of sodium bicarbonate (NaHCO₃) ingestion on performance, blood gases and selected plasma parameters before and after maximal exercise in athletes. The subjects were 7 male high school kayakers players, and the experiments were conducted, twice. The dose of NaHCO₃ was 300mg/kg, and taken 90 minutes before the exercise. The experimental results were summerized as follows: Comparative observation of blood gases levels such as O₂SAT was much changes and tend to be increased in NaHCO₃ ingestion group than that of control group before and after exercise. However, O₂CT level was not so much changes in NaHCO₃ ingestion group than that of control group. Also, blood lactate and LDH levels were displayed a significantly decreased after sodium bicarbonate treatment, when compared with control group.

The purpose of this study was to investigate the change of activities of CPK LDH and isozymes related to different technique levels during man's floor exercise in gymnastics, The subjects participated in this study were 8 male gymnasts from H university and they were divided into two groups (high-skilled 4, low-skilled 4) CPK, LDH and Isozymes were analyzed by the level of ability to perform floor exercise in order to investigate the level of muscle damage and exercise intensity and the types of energy supply. The results of the study were as follows : 1. The high-skilled group(??=403.50) had a significantly greater activity of total LDH(p<.05) than low-skilled group(??=364.48) and there were significant difference among LDH activities by treatment periods in high skilled group(p<.001). 2. It showed that there were significant difference among CPK activities by treatment periods(p<.05) and significant difference among CPK activities by treatment periods by groups(p<.01). However there were no significant difference by groups. 3. During man's floor exercise, it showed that there were no significant difference between lactate concentration by groups but significant difference among lactate concentration by treatment period(p<.001) 4. During man's floor exercise, there were no significant difference between HR by groups but average HR tended to be increased by treatment period(p<.001) and there were significnat difference among HR by treatment periods by groups(p<.001) In conclusion, both high-skilled group and low-skilled group didn't appeare to be significant difference in lactate concentration and HR which were usually changed by exercise intensity. However there were significnat difference in total LDH and CPK activities during the recovery periods(high-skilled group is treater than low-skilled group). Therefore, we can think that floor exercise wes regarded as exercise using ATP-PC system rather than using anaerobic energy system like lactate. Also we can assess muscle damage which can be caused by performing man's floor exercise performed by person who has different ability to execute several skills. finally, In order to improve the level of performing floor exercise, I think we predominatly have to select powerful and acute muscle strength training to be used by ATP-PC system for energy.

The purpose of this study estimated whether a life style and diet pattern or natural phenomenon induced to aging in changes of plasma lipid component. Also, It was estimated from the changes of plasma lipid component followed acute maximal swimming exercise in different aged rats. Three months, nine months and sixteen months male rats of a Sprague-Dawley were housed in individual cages, and they were separated into each two group. - 3 month (12) : Control (6) and Experimental (6) - 9 month (22) : Control (10) and Experimental (12) - 16 month(16) : Control (8) and Experimental (8) In the 3.9.16 month, half of control group was randomly sacrificed. The other half of experimental group was performed with swimming exercise until exhaustive state. Water tank of 50cm depth and 50cm diameter was used for this study. Rats were given a 5 min warm up with swimming exercise, this warm up was followed by taking 5 min rest period, then animal exercised until exhaustion. Plasma cholesterol, HDL, LDL and TG levels followed aning of 3,9 and 16 months was not shown a significant difference between control group. Also, Plasma cholesterol, HDL and LDL levels of experimental group was not displayed statistically significant difference between 3,9 and 16 month group, but there was a significant difference(p<.05) between control and experimental group of 16 month, and between experimental group of 3 month and 16 month(p<.05) in levels of triglycerides. Conclusively, This study suggested that changes of plasma lipid component induced by aging was not phenomenan due to increase of age, and conditions except for life style and diet patern, etc. was similar to a changes of lipid component induced as exercise.

고도로 훈련된 중, 장거리 런너(n=10)를 대상으로 단시간내에 최대상태(Exhaustion)에도달하도록 하는 점증적 트레드밀 운동을 실시 하였을때 혈장의 젖산탈수소효소(LDH)및 젖산탈수소 동위효소(LDH isozyme)를 분석함으로서 운동의 형태에 따른 조직의 상해 및 근섬유동원양상을 평가하고자 안정시와 운동직후 및 회복 30,60분에 주저정맥에서 약 5ml의 혈액을 채혈하였다. LDH활성도는 Beckman paragon법을 이용하여 측정 하였으며, LDH isozyme을 전기영동분리하고 scanning desitometer를 이용하여 상대적 %를 산출 하였다. 중, 장거리 런너들에서 점증적 트레드밀 운동부하후 혈장의 LDH활성도는 안정시에 비해 다소 증가 되었으나 통계적 유의차(p>0.05)는 없는것으로 나타났으며, 회복 30분과 60분에서도 안정시 및 운동직후 수준과 유의한차(p>0.05)는 없는것으로 나타났다. LDH isozyme은 운동직후 H-type(LDH1+2)에서 감소되는 경향을, M-type(LDH3+4+5)에서 증가되는 경향을 나타내였으나 통계적 유의차(p>0.05)는 없는 것으로 나타났으며, 회복의 시간경과에 따라서도 유의한차(p>0.05)는 없는 것으로 나타났다. 이러한 연구결과가 시사하는 바는 혈장의 젖산탈수소효소 및 젖산탈수소 동위효소의 변화는 운동의 형태에 따라 차이를 나타낸다는 것과, 현재에 이용된 트레드밀의 강도와 기간이 이들의 변화를 유발 시키기에는 불충분 하였다는 것으로 결론 지을수 있을 것이다. The pupose of this study was to estimate a damage of tissues and a recruitment patterns of muscle fibers followed exercise types by analyzing the plasma lactate dehydrogenase (LDH) and distribution of lactate dehydrogenase isozymes. The subjects for this study consisted of 10 middle and long distance runners. Venous blood samples of 5ml were collected before and after 2min incremental treadmill exercise, also in the 30,60min of recovery. Total LDH aetivity was examinated by using a Beckman paragon techniques. Also, LDH isozymes was determined to electrophoresis separation by using agarose gel buffered in paragon LD isoenzymes kit. This distribution of LDH isoenzymes was calculated from a relative percentage by scanning densitometer. Plasma total LDH activity after treadmill exercise did not statistically significant. difference(P>.05), and did not differ 30,60 minutes of recovery compared with treadmill exercise before. Distribution of LDH isozymes resulted in decreased of LDH H-type (LDHl+2), whereas LDH M-type(LDH3+4+5) increased, but did not statistically significant difference(P>.05) compared with exercise before. We conclude that Changes of plasma lactate dehydrogenase and lactate dehydrogenase isoenzymes differ as exercise types. And exercise intensity and duration of treadmill used to this research is not suitable to inducing a changes of these enzymes.
