The purpose of this study was to investigate the effect of exercise theraphy on visceral fat distribution. With nine women students at K college swimming program was performed thirty minutes 3 times a week for 12 weeks. The conclusion is as follows: Body composition such as % fat, fat mass, abdominal circumference significantly decreased by this swimming program, Visceral fat and subcutaneous fat had tendency to decrease, but not statistically significant. Careful caution is needed in estimating the change of visceral fat through the change of body composition only by circumference measurement.

hydroxycitric acid is ingredient extracted from in the rind of fruit garcinia cambogia. HCA is an an inhibitor of ATP-citrate lyase, a cytosolic enzyme that catalyses the cleavage of citrate to oxaloacetate and acetyl-CoA. It has been hypothesized that HCA ingestion can reduce malonyl-CoA concentrations and consequently increase fat metabolism. In this study, the short-term effects HCA on energy substrates utilization during exercise were examined in untrained women. Seven subjects ingested 500㎎ of HCA or a placebo for 5days and did exercise. HCA tended to significantly decrease the respiratory exchange ratio and lactate concentration during 1h of exercise. These results suggested that short-term administration of HCA promotes fat oxidation and spares glycogen utilization during exercise.

본 연구는 K여자대학 평생교육원에 참가한 50명의 중년여성중 비만자로 판정된 11명을 대상으로 3개월간의 수영프로그램이 비만여성의 생리학적 변인에 미치는 영향을 알아보기 위한 것이었다. 모든 피검자들은 일주일에 5회씩 3개월간 수영을 수행하였다. 1회 운동시간은 50분으로 하였으며, 각 영법을 35분, 기술훈련(손동작, 평영발차기)을 15분간 실시하였다. 첫 4주간은 발차기(보드잡고, 자유형, 배영)를 하였고, 5주째부터 운동프로그램이 종료될 때까지 자유형, 배영, 평영 및 각 영법의 발차기를 병행하였다. 수영프로그램중 모든 피검자는 하루에 1,000m씩 수영을 하였다. 식사에 의한 영향을 배제하기 위하여 주 1회 전문지도자에 의해 식사지도를 하였으며, 식사기록에 의해 평상시 섭취량을 유지하도록 최대한 지도하였다. 3개월간의 수영프로그램에 참가한 비만 여성들은 체중과 체지방율 등의 인체측정학적 변인들이 유의하게 감소되었고, 최대산소섭취량은 유의한 증가를 보였다. 혈압은 큰 변화가 없었으나, 혈중 지질성분은 긍정적인 경향을 보여 3개월이라는 비교적 단기간에서도 비만여성의 수영프로그램 참가가 효과적이라는 것이 확인되었다.

To examine the effect of carnitine and caffeine administration on endurance performance in athletes, we made a comparative analyses of the utilization of energy substrates, hormone response and exhaustion time through the single and complex administration of cartinine and caffeine. The results are as follows: 1) As to the respiratory quotient during exercise, the group of carnitine and caffeine complex administration and that of caffeine administration were significantly lower than that of water administration at the 40 and 45 minutes. The group of carnitine administration was also low, but it was not so significant. There was no difference between each group in the oxygen consumption during exercise, the glucose concentration and the triglyceride concentration. The lactate concentration increased in the case of the group of caffeine administration and that of carnitine and caffeine complex administration in comparison with other groups but the difference was not so significant. The free fatty acid concentration during exercise increased continuously in all groups, the rate of increase was lower in the group of carnitine administration and that of carnitine and caffeine complex administration than in the group of water administration and that of caffeine administration. Especially after the 40 and 45 minutes, it was significantly lower in the group of cartinine and caffeine complex administration than in that of caffeine administration. 2) The insulin concentration during exercise tended to decrease continuously in all groups, but there was no significant difference in each group. Epinephrine and norepinephrine showed no difference between each group. 3) The amount of all out time to exhaustion period could be ordered as follows: the group of carnitine and caffeine complex administration, that of carnitine administration, that of caffeine administration and that of water administration.

The purpose of this study is to investigate the effect of endurance training and L-arginine supplementation for 6 weeks on energy substrate utilization and endurance performance during exercise in female students at K college. The respiratory quotient decreased in the case of endurance training treated group in comparison with water treated group, but L-arginine treated group is increased. The glucose concentration decreased L-arginine treated group in comparison with water treated group at the 0 and 15 minutes during exercise. The lactate concentration decreased in the case of endurance training treated group and L-arginine treated group in comparison with water treated group from 15 to 60 minutes during exercise. The triglyceride and insulin concentration showed no difference between each treated group. The free fatty acid concentration increased in the case of endurance training treated group in comparison with water treated group from 30 to 60 minutes during exercise, but L-arginine treated group is decreased. The glucagon concentration increased in the case of L-arginine treated group in comparison with water treated group from 15 to 60 minutes during exercise, The amount of all out time to exhaustion period could be ordered as following: water treated group 69.22min, L-arginine treated group 77.11min, endurance training treated group 80.00min. These results suggested that L-arginine supplementation may increase endurance performance same as endurance training.

  The purpose of this study is to examine the validity in evaluation of maximal oxygen uptake by the lean body mass. Through tests and analyses of ten woman object students attending S college, we can draw following conclusions:<BR>  1) In evaluation of maximal oxygen uptake by the lean boby mass, the analised amount of maximal oxygen uptake is overestimated in case the rate of body fat is high.<BR>  2) Even in case of low scored physical fitness, the overestimated amount of maximal oxygen uptake per lean boby mass leads to misinterpretation of physical fitness.<BR>  Consequently it follows that the evaluation of maximal oxygen uptake by the lean body mass dose not provide any useful variable in estimation of physical fitness, great care should be taken in applying to the analysis of exercise performance.

The purpose of this study was to investigate the relation of visceral fat to cardiovascular disease risk factors in obese women. It was observed that carefulness was needed in estimating of visceral fat caused by anthropometric variables through this study. There was no correlation between maximum oxygen uptake and visceral fat. It was investigated that the cardiovascular disease risk factors had more significant correlations with visceral fat than subcutaneous fat. Accordingly the cardiovascular disease risk factors can be prevented and improved without changes of anthropometric variables such as body weight in case of decrease in visceral fat.

수영이 비만여성의 심혈관 질환 위험인자에 미치는 영향

최성근(Choi Sung-Keun) 한국체육과학회 2005 한국체육과학회지 Vol.14 No.2

The purpose of this study was to investigate the effects of a swimming program on risk factors for cardiovascular disease in obese women. This swimming program was completed by 31 women who were attending the Lifelong Education Center at K college and consisted of swimming 1,050 meters in 60 minutes, 4 times a week for 6 months. The conclusions of this swimming program were as follows: Body composition, as measured by body weight, percent fat, and abdominal girth, significantly decreased, and maximal oxygen uptake, as measured by the cardiopulmonary representative index, significantly increased through this swimming program. It was also observed that this swimming program seemed to contribute to reducing risk factors for cardiovascular disease as blood pressure and total cholesterol level significantly decreased. Therefore, the effects of aerobic exercise on reducing the risk factors for cardiovascular disease in obese women seems to be effective as seen through the evaluation of change in body composition and maximal oxygen uptake.
