The aim of this study was to investigate the effects of an acute exercise bout in the morning in the post-absorptive or postprandial state on the metabolism and fatigue factors. Ten young males(age: 20.2±1.9 years) were studied in a crossover design comparing two conditions: post-absorptive and postprandial exercise(at 75% of individual VO2max until 400kcal consumed). One week post-recruitment, the subjects exercised in the morning after an overnight fast. At 2 weeks, they exercised post-breakfast. Metabolism(glucose, free fatty acid, insulin, growth hormone, and cortisol) and fatigue(lactate, ammonia, inorganic phosphate) levels were measured immediately before and after exercise and at 60 min post-exercise. Results of this study, an effect of interaction among glucose(p=.007), insulin(p=.002) and inorganic phosphorous(p<.001) was represented meaningfully. In the morning post-absorptive exercise, area under the curve of free fatty acid(p=.017), growth hormone(p=.038), cortisol(p=.016) and inorganic phosphorous(p=.018) was represented more significantly than postprandial exercise. Post-absorptive exercise can be more effective in reducing body fat than postprandial exercise. However, increased cortisol and inorganic phosphate levels following exercise after overnight fasting may negatively affect long-term weight loss.

The purpose of this study was to investigate the effect of endurance training in three different climatic conditions on leukocytes and NK cell by submaximal exercise. 18 male subjects were separated 3 groups based on climatic conditions (temperatureㆍrelative humidity). Each group was trained using bicycle ergometer in an chamber. The changes of leukocytes and NK cell are measured during submaximal exercise test at rest, post- exercise and recovery 60 minute in pre- and post-training periods. After the post-exercise and 60 minute recovery, the leukocytes and neutrophils count of all three groups significantly decreased more in post-training than in pre-training. There were no significant differences observed among three groups on the lymphocytes count. When submaximal exercise test executed in pre-training, the lymphocytes count of all groups decreased after 60 minute recovery than at rest, but the low temperature group showed an increase of a few lymphocytes. The natural killer cell count of rest and post-exercise decreased in post-training than in pre-training, but it increased after 60 minute recovery in post-training. Especially, the high temperature group has shown significant increase at recovery 60 minutes in post-training than in pre-training.

The purpose of the current study was to compare anthropometrics. obesity indices, cardiorespiratory fitness, and obesity-related metabolic syndrome markers between non-obese group (n = 35) and obese group (n = 32) according to the UCP2 gene I/D polymorphism. Body mass index of ≥25 kg/m² along with ≥20% body fat were used as the criteria for obesity classification. Apparently healthy subjects aged between 20-30 years were recruited via flyers and local advertisements on a campus news letter. Following an overnight fasting, the subjects visited to our laboratory three times on separate days. On the first visit, anthropometrics and body composition were measured. On the second visit, blood samples taken from an antecubital vein were used for the determination of the UCP2 genotype, blood lipids, glucose, lactate levels. VO₂max and 1 minute recovery heart rate were measured on a motor-driven treadmill using the Bruce protocol. On the final visit, resting metabolic rate was determined via an indirect calorimetry by using a metabolic cart. The result of the current study showed significant differences in resting DBP (p=.028), TG/HDL-C ratio (p = .027), and fasting TG concentration (p = .052) between the genotypes in the obesity group, while no significant genotype-specific differences were found in any of the measured variables in the non-obese group (p<.05). Stepwise multivariate regression analysis showed that 1) UCP2 genotype explained up to 31.1% of individual variation in resting DBP, 2) both UCP2 genotype and body fat explained up to 31.9% of individual variation in TG/HDL-C ratio, and 3) WHR explained 27.1% of individual variation in fasting TG concentration. In conclusion, the current findings suggest that the UCP2 DID genotype is associated with resting DBP and blood TG concentration in the obese group of the study population but not in the non-obese group, indicating a possible interaction between the UCP2 gene and obesity in the development of the obesity-related metabolic syndrome.

The purpose of this study was to discuss on the preceding studies that is related to bring about the fatigue during submaximal exercise, to make propose an alternative plan on the suppression of blood lactate and ammonia concentration. In general, the fatigue is gave a definition that does not give full play or maintain one's force and power. The fatigue is classified into the central fatigue and peripheral fatigue. There is a controversy on the fatigue that is caused by the center or periphery so far. The discussion on the preceding studies proved the methods of inhibition of the increase in lactate and ammonia during submaximal exercise. We meditated that OKG administration is an effective method to decrease lactate and ammonia by increasing the concentration of glutamate in human body. In other words, we have observed that OKG administration prior to submaximal exercise can improve the exercise capacity and the rate of recovery after exercise.

이 한, 홍미경, 신선애, 손태열, 안의수, 김완수, 홍 용. BCAA섭취가 중추피로변인 및 지구성 운동수행 능력에 미치는 효과. 운동과학, 제11권 제1호, 25-34, 2002. 본 연구는 탈진적인 지구성 운동시 BCAA (Branched-chain amino acid)섭취가 중추피로의 주 요인인 세로토닌 및 암모니아 농도와 지구성 운동수행능력에 미치는 효과를 실험적으로 구명하는데 목적을 두었다. 실험대상자는 고등학교 싸이클 선수 9명으로 각 피험자의 70%VO_2max의 강도로 자전거 에르고메터를 이용하여 탈진시까지 운동을 실시하였으며, BCAA는 피험자의 체중당 78㎎을 역삼투수 500㎖에 용해시켜 구강 섭취하였다. BCAA와 위약섭취시기의 실험조건을 동일하게 하였으며, BCAA와 위약을 교차하여 섭취하는 무작위처치를 이용하였다. 채혈은 카테터를 전완정맥에 삽입하여 제재섭취전, 제재섭취 50분 후, 운동중 30분, 운동직후(탈진) 및 회복기 30분에 각각 10㎖씩 채혈하였다. 혈장 BCAA 및 BCKA치 농도는 BCAA섭취시 유의하게 증가한 것으로 나타났으며, 혈장 암모니아농도는 운동시 BCAA섭취에서 증가하였지만 유의한 차이를 나타내지는 않았다. 혈중 젖산 및 혈장 트립토판의 농도는 BCAA섭취 시 감소하였으나 유의한 차이는 없었으며, 혈장 세로토닌 농도는 BCAA섭취 시 유의하게 감소한 것으로 나타났다. 또한, 주관적 운동강도(RPE) 및 지구성 운동수행시간은 BCAA섭취 시 증가하였으나 유의한 차이는 나타나지 않았다. Lee, K, Hong M.K., Shin, S.A, Son, T.Y., Ann, ES., Kim, W.S., Hong, Y. The Effect of BCAA Administration on the Central Fatigue and Endurance Exercise Capacity. Exercise Science, 11(1): 25-34, 2002. The purpose of this study was to estimate the effect of the BCAA(branched-chain amino acid) administration on serotonin and ammonia concentrations that were central fatigue main factors, and endurance exercise capacity during exhaustive endurance exercise. 9 male cycle players of high school were chosen as subjects of this study, and BCAA(78㎎/㎏·w) solved in distilled water 500㎖ were administrated to them and exhaustive endurance exercise was executed by using 70%VO_2max intensity to cycle ergometer. Experimental conditions of BCAA and placebo administration were the same and randomized ingestion were used. The time of inserting catheter was earlier agents administration and the blood sampling time were just before agents administration, 50minutes after agents administration, exercise 30 minutes, exhaustion, recovery 30 minutes, 10㎖ blood was taken. Plasma BCAA and BCKA concentrations were significantly increased (p<.05) when BCAA administration, plasma ammonia concentration was increased when BCAA administration but there was not significant. Blood lactate and plasma trytophan concentrations were decreased when BCAA administration but there was not significant, plasma serotonin was significantly decreased(p<.05) when BCAA administration. RPE and exercise time were decreased when BCAA administration but there was not significant.
