Most of elite sports player during the sports competing and trainning have used the mineral supplements to enhance on the human performance and, also a number of researcher have recommended the mineral supplements of RDA(Recommended Dietary Allowance) for them. However, It has not exactly known to the scientific interpretation and evidences of relationship between human performance and mineral. Thence, The purpose of this study was to prove whether the mineral supplements of high RDA could enhance the sport player's performance or not The subjects of this study were composed of sixteen Rugby football players(experimental group=8, high density multimineral water intake for 30days; control group=8, placebo intake)in K-H University. Both of groups were tested three times(pre=before intake, mid=after 15days supplements, post=after 30days supplments) about maximum anaerobic power(MAnp) and maximum oxygen uptake by bicycle ergometer(868), muscle strength and muscle endurance by isokinetic Cybex system(350). The statistical analysis employed this study was t-test by statistic 512+ program in machintosh computer. The result of this study were appeared that the difference in control and experimental group signified that the experimental group was high more than the control group in left knee extensor's peak torque at mid-test(P<.05), in left knee extensor's total work(%BW) at mid-test(P<.05), in left extensor's average power and average power(%BW) at mid-test(P<.05). Relative maximal oxygen uptake(㎖/LBMkg/min) in experimental group was higher than control group after 30 days the mineral supplements. These results suggest that the high density multimineral water intake should influence partially rugby football player's performance by the increment of muscle endurance and maximal oxygen uptake.

In this study, we conducted graded maximum exercise test to normal people(male 112, female 108) using cycle ergometer. We calculated heart rate which corresponds heart rate threshold(HRT) and lactate threshold(LT), ventilation threshold(VT) through the test. After that, we divided data(n=220) randomly using Bernoulli"s trials. 70%(actually 70.5%) of data were used as analysis data(male 79, female 73) and 30%(actually 67.6%) were used as validity test data(male 33, female 35). Using analysis data, we conducted simple regression analysis. Independent variable was HRT and dependent variable was HRLT, HRVT which represents heart rate corresponds anaerobic threshold. The adjusted R<SUP>2</SUP> was mean 72.3% and SEE was mean 8.96 bpm. Moreover, in validity test, SEE was 8.54bpm which was similar to developed regression model. So we identified developed regression model is valid. These results show that HRT is meaningful variable to predict HRLT, HRVT and very important variable to estimate anaerobic threshold.

The aim of present study was to investigate acute decrease reasons of submaximal aerobic performance at the whole and local body level. For the present study, 14 health male was chosen out of 20 volunteers. Subjects performed exercises that consist of 30min bicycle exercise at a 75%HRmax on simulated altitude of sea level, 2,000m, 3,000m, 4,000m and 5,000m. Each exercise was performed at intervals of three days to eliminate repetition effect. During the exercises, whole and local body level parameters were measured at rest, 4min, 8min, 20min, 30min. Whole body level parameters were aerobic performance(watt) at 75%HRmax, %SpO₂, blood lactate concentration and local parameters were oxygenation in skeletal muscle, RBC deformability. As a result, aerobic performance(watt) at 75%HRmax was decreased acutely on higher altitude than 4,000m as compared with lower altitude than 3,000m. This decrease was caused by increase of blood lactate concentration and decrease of O₂Hb. Because PO₂ was decline, oxygen transportation capacity was decrease. These factors lead to increase of blood lactate concentration and decrease of O₂Hb. In addition, elongation index(EI) of RBC at 5,000m were lower than sea level or 2,000m.

The purpose of this study was to propose types of hypobaric hypoxic training for cardiopulmonary function and oxygen transporting capacity. Eighteen university basketball players were divided into H.L group (Living High & Training Low, n = 9) and L.L group (Living Low & Training Low, n = 9) according to hypoxic exposure. Oxygen transporting capacity, body composition, maximal oxygen uptake, blood lactate concentration, cardiopulmonary function and heart rate were investigated. Results were as follows. 1. There was no significant difference on body composition inter group or among several test time. 2. After exposure, heart rate was significantly low in H.L group. And there was significant difference inter group or among several test time. 3. Maximal oxygen uptake was significantly high by exercise time increase but there was no significant difference inter group or among several test time. 4. Blood lactate concentration was increased after exposure but there was no significant difference inter group or among several test time. 5. According to training period increase, there was no significant difference on RBC, EPO but Hct, Hb concentration were significantly lower than after Iweek exposure. But there was no significant difference inter group or among several test time. 6. In hypobaric hypoxic environment, heart rate during sleeping was significantly decrease as time goes by. 7. In hypobaric hypoxic environment, oxygen saturation during sleeping was significantly increase as time goes by. As a result, passive exposure in hypobaric hypoxic environment was not significantly efficient on body composition, blood component and blood lactate concentration but heart rate during exercising and sleeping was significantly low and exercise time and maximal oxygen uptake increased. It could be a possibility.

The purpose of this study was investigate that response of blood lactate concentration and blood gas during 80%HRmax cycle exercise and account for exercise performance decrease through acid-base balance. Ten healthy men participated in the study. The subject performed 30min cycle exercise at sea level, 2,000 m normobaric hypoxic environment, and 4,000 m normobaric hypoxic environment. Blood lactate concentration, PO₂. PCO₂, pH, HCO₃-, and ScO₂ during cycle exercise were measured. The collected data were processed statistically by repeated one-way ANOVA and LSD. As a results, cycle load for maintain 80%HRmax at 12.8% O₂ significantly decreased compared to 16.5% O₂ and 20.9% O₂. Blood lactate concentration at 12.8% O₂ was significant increase compared to 20.9% O₂ and presented increase tendency compared to 16.5% O₂. Meanwhile, pH at 12.8% O₂ presented constant or increase tendency compared to 20.9% O₂, despite blood lactate concentration at 12.8% O₂ was significant increase compared to 20.9% O₂. At 12.8% O₂, PO₂ and PCO₂ was significant decrease compared to all other simulated environments. HCO₃- presented most decrease tendency compared to all other simulated environments. Overall, blood lactate concentration at 12.8% O₂ was highest because carbohydrate dependence increase as the oxygen partial pressure is decrease. Also, despite blood lactate concentration was significant increase, pH maintained. These results that PCO₂ is removed through pulmonary ventilation increase caused by hypoxic ventilation response.

The purpose of this study was to offer the basic data for the effective power training program. And the ball game athletes and the martial art athletes - they had a different exercise pattern - were chosen in the study as subjects. After we measured the power of physique and various leg extension power movement, we examined the power characteristics of each sports and group. The results of study were as follows. 1. Among the physique factors except the rate of body fat and the calf length, the ball game group was significantly superior to the martial art group. Particularly thigh girth of any other group's, the calf girth of rugby and handball was so. 2. For the reaction time of the whole body largely controlled by the function of nervous system, that of handball athletes was faster than that of any other ball game group's and that of taekwondo athletes was faster than that of any other martial art group's. But there was no significantly difference between the ball game group and the martial art group. 3. In terms of the sargent jump and the standing board jump, that of the ball game group's as significantly higher than that of the martial art group's. And volleyball athletes were outstanding among the ball game group, judo athletes were so among the martial art group. 4. For maximum anaerobic power(㎏m/L.B.M./sec), that of martial art group's was significantly high. 5. Total leg extension power(L.E.P.) at the load body weight, 120% body weight, and 80% body weight appeared high in order of judo, rugby, volleyball, handball, taekwondo, boxing and it appeared significantly low in martial art group. But there was little difference between group, when we made a comparison with total L.E.P./L.B.M. When we divided total L.E.P. into force, speed factor and then compared, the force factor of the ball game group's was significantly higher than that of the martial art group's in all load conditions. In addition to, the speed factor of the ball game group's was significantly higher than that of the martial art group's in the load of 80% body weight. 6. Leg extension speed(L.E.S.) of the ball game group's was significantly faster than that of the martial art group's in all load conditions. As our results above, the ball game group had the good speed factor among the power composition factor. So the ball game group needs muscle-strength-training by high-load-weight training, the martial art group needs complex forcing training of force and speed factor.

The purpose of this study was to investigate the change of blood pressure, blood lipids, and ADL after a long duration elastic band training. The subjects of study consist of two groups(group A : exercise group, group B : control group ; 68~78 years)of hypertensive, who are the residents at Silver Town in Y City. The results of this study were as followings; 1. Group A had no significant difference for weight, fat mass and body mass index but soft lean mass and fat free mass increased significant difference and %body fat decreased significant difference between pre and post of the program. There was no significant difference between pre and post of the program in Group B for all of body composition. 2. There was significant difference between group A and B on the change of blood pressure for every weekly. The blood pressure of group A was from 139.2/82.8 mmHg to 128.4/75.8 mmHg and group B was from 137/76.6 mmHg to 141.4/82.8 mmHg. The blood pressure of group A decreased by significant difference but group B increased by significant difference. 3. There was no significant difference for total cholesterol, high density lipoprotein and triglyceride, but low density lipoprotein was significant difference between pre and post of the program in group A. Group B had no significant difference between pre and post of the program for blood lipids. 4. All of ADL(activity of daily living) was improved by significant difference between pre and post of the program in group A. There was significant difference only for sit and reach of ADL between pre and post of the program in group B. The results of study suggested that it was possible to introduce the technology of alastic band for the health care program of elderly people because the resistant training through elastic band of the proper intensity was useful for the improvement of higher pressure and ADL in hypertensive elderly women for 10 weeks.
