Today Human Personal Trainers are becoming very famous in this health conscious world. They teach user to achieve fitness goals in managed way. Due to their high fee and tight schedule they are unavailable to mass number of people. Another solution to this problem is to develop digital personal trainer portable instrument that may replace human personal trainers. We developed a portable digital exercise trainer device - BIOFIT that manages, monitors and records the user's physical status and workout during exercise session. It guides the user to exercise efficiently for specific fitness goal. It keeps the full exercise program i.e. exercises start date and time, duration, mode, control parameter, intensity in its memory which helps the user in managing his exercise. Exercise program can be downloaded from the internet. During exercise it continuously monitors the user's physiological parameters: heart rate, number of steps walked, and energy consumed. If these parameters do not range within prescribed target zone, the BIOFIT will alarm the user as a feedback to control exercise. The BIOFIT displays these parameters on graphic LCD. During exercise it continuously records the heart rate and number of steps walked every 10 seconds along with exercise date and time. This stored information can be used as treatment for the user by an exercise expert. Real-time ECG monitoring can be viewed wirelessly (RF Communication) on a remote PC.

본 연구는 운동중독이 신체적, 정서적 삶의 질적 가치에 영향을 줄 수 있다는 전제하에 운동참여자의 사회인구학적특성에 따른 운동중독과 정서의 성향을 분석하고 운동중독과 정서는 어떠한 관련성이 있는지를 규명하여 운동참여자의 운동중독을 예방함과 동시에 합리적인 대처방안을 제시하고자 고찰하였다. 그 결과, 운동 참여자들은 테니스를 통하여 본인의 건강 유지 증진에 대한 심리적, 정서적 안녕감이 크게 작용하고 신체적인 기술성취의 중요성으로 인하여 운동중독현상과 더불어 긍정적, 부정적인 정서에도 유의한 영향을 미친다는 결과가 나타났다. 이러한 사실을 상기하여 각 개인에게 긍정적 참여행동을 주지시키는 것은 물론 지도자들은 테니스 운동 참여자들이 보다 긍정적인 운동수행이 되도록 운동 참여행동을 제시하고 이러한 행동을 지속적으로 수행해 나갈 수 있도록 하는 것이 건강을 위한 여가의 한 형태로서 테니스 운동참여가 이루어질 수 있는 올바른 방향이라 사료된다.

This study was directed to further clarify the effect of resting time or dietary condition for the improvement of exercise capacity and physical fitness, and the changes of some body consitiuents and physiological functions which are related to the exercise metabolism. Sixteen male students(8 athletes and 8 nonathletes)were participated during 3 weeks(Aug. 20-Sep.9, 1989). Each subject performed two treadmill running trials at an absolute intensity (1 mintute in 3.4mph/15% slope and 2 minutes in 5.5mph/20% slope). In the resting time trials, general diet was fed before 1, 2, 4 and 12 hours of the treadmill exercise loaded. in the dietary condition trials, high carbohydrate(HC), high fat(HF) and high protein(HP) diet were fed before 2 hours of the treadmill exercise loaded. Control trial was that of resting time before treadmill exercise loaded after 12 hours of general diet feeding. Measurement were made to study the change of blood glucose, palmitate, lactate, blood pressure and heart rate. The results obtained are summarized as follows: Mean daily metabolizable period. In resting time trial, the blood glucose concentration of athlete and nonathlete from 2 hours group was similar to control group. The blood palmitate concentration of athlete was increased in 1 and 2 hours group but those of nonathlete was not only increased in 1 and2 hours group but was more increased in 12 hours group, compared with both control group. The blood lactate concentration was increased in all experimental group, compared with both control group and those of nonathlete was much higher than athlets. The elevation rate of blood pressure in pre-and after-exercise of athlete was lower than those of nonathlete. In dietary composition trial, the blood glucose concentration of athlete and nonathlete in HC group was higher than other diet groups. The blood lactate concentration of athlete and nonathlete in HC group was lower than other diet groups. There was no remarkable change of the blood palmitate concentration and heart rate in each dietary composition trial, but those of nonathlete was low in HC and high in HP group. In above results, it was suggested that the effective condition of resting time and dietary composition for the improvement of exercise capacity of nonathlete may be 2 hours and HC diet, respectively. But it was showed that the exercise capacity of athlete may not be affected by experimental condition of resting time, except 1 hour after feeding or of dietary composition because of well adaptation in new exercise condition.

Purpose: This study aimed to investigate the effects of postural control exercise on the delayed heart rate increase in heart transplant patients. Methods: The subject was a female heart transplant recipient who had a delayed increase in heart rate during exercise. The intensity of exercise was performed at MBorg level 4. The A-B-A' and A-B-A'-B' designs were used to identify the changes in heart rate during active-assisted exercise, lower limb postural control exercise, and upper limb postural control exercise. Experiments were performed for four weeks. The heart rates at pre- and post-exercise were compared, and the time to reach MBorg 4 was measured. Results: In the active-assisted exercise, the average heart rates at pre- and post-exercise and after 10 min of exercise were 88, 89, and 87.7 bpm, respectively. In the repetitive comparison of pre- and post-exercise in the lower limb postural control exercise, the difference in the mean heart rate was 3.5 and 3 bpm in stable support and 14 and 14.5 bpm in unstable support, respectively. In the repetitive comparison of pre- and post-exercise in the upper limb postural control exercise, the difference in the mean heart rate was 6 and 4 bpm in stable support and 4 and 4.5 bpm in unstable support. The time required to reach MBorg 4 was short when both the upper and lower postural control exercises were performed in an unstable state. Conclusion: We suggest that combining proper postural control exercise with strength exercise and aerobic exercise, among others, may be effective in rehabilitating patients in the recovery stage after a heart transplant.

We examined the effects of the NADPH oxidase p22phox C242T polymorphism on endurance exercise performance and oxidative DNA damage in response to acute and chronic exercises. One hundred three subjects were recruited, among which 26 healthy subjects (CC: 12, TC: 12, and TT: 2) were studied during rest, exercise at 85% $VO_2max$, and recovery before and after 8 weeks of treadmill running. Lymphocyte DNA damage increased significantly in response to exercise (p < 0.05). There were no significant differences in plasma MDA, SOD concentrations and lymphocyte DNA damage between CC genotype and T allele group, but significant endurance training differences were observed. Endurance training increased exercise time to exhaustion in both the CC genotype and T allele groups (p < 0.05) but no significant difference was found between groups. The results of the current study with young, healthy, Korean men are interpreted to mean that 1) the majority had the CC genotype of the NADPH oxidase p22phox C242T polymorphism (82.5%: CC, 15.5%: TC, 1.9%: TT), 2) acute exercise increased lymphocyte DNA damage, 3) endurance training significantly increased exercise time to exhaustion, and alleviated lymphocyte DNA damage, and 4) The NADPH oxidase p22phox C242T polymorphism, however, did not alter lymphocyte DNA damage or exercise performance at rest, immediately after exercise, or during recovery.

In this study, we have figured out exercise time and the amount of burned calories, using a three-axis acceleration sensor which we name as a health sensor. What is more, the health sensor calculates the degree of physical exercise taken during exercise. As is generally known, continuing, regular exercise is far more effective than short time exercise for sustainable health management. The health sensor is, therefore, recommended as an instrument to efficiently carry out the health management. Additionally, the health sensor was applied as an exercise subsidiary system to walking and jumping rope tests. In light of their results, the sensor system was found useful for analyzing the pattern of exercise.

We studied the effects of behavior modification and aerobic exercise on body weight, degree of obesity, % body fat, triceps skinfold thickness, blood pressure and eating behavior among overweight middle school girls. 15 girls participated in the behavior modification program by joining 60-90 minute group session weekly. The aerobic exercise program was given to 13 girls 3 times per week with 60 minutes each time. The data were obtained before treatment, after 4 and 8 weeks after treatment. In analyzing the data, repeated measures ANOVA were adopted. The results were as follows ; 1. For the changes of body weight between 2 groups, body weight of behavior modification groups decreased significantly than these of aerobic exercise group at 4 and 8 weeks after treatment, 2. For the changes of degree of obesity between 2 groups, there were no significant differences over time, 3. The analysis of change of % body fat did not reveal significant differences between 2 groups over time, 4. The changes of triceps skinfold thickness were significant differences between 2 groups over time, 5. For the changes of systolic blood pressure between 2 groups, there were significant differences over time. At 4 weeks after treatment, systolic blood pressure of behavior modification group decreased significantly than these of aerobic exercise group. 6. The changes of diastolic blood pressure were significant differences between 2 groups over time.

The purpose of this study was to evaluate changes of body composition, cardio-respiratory function in ventilation threshold (VT) and maximal state exercise, systolic (SBP) and diastolic blood pressure (DBP) and serum nitric oxide (NO) production during acute reducing salt (RS) supplementation in college elite athletes. Variables of cardio-respiratory function during rest, ventilation threshold and maximal exercise was not shown a significantly difference between RS supplementation and non-supplementation, there was shown a significant increase in ventilation threshold time (p<0.05) and exhaustion time (p<0.05) during RS supplement compared to non-supplement. SBP and DBP were not shown a significant difference between RS supplement and non-supplement. This result suggests that acute intake of RS is not increased a blood pressure. Serum NO production was not significant difference in the RS supplement group, but it was shown a significantly increased levels (p<0.01, vs. recovery 30 min.) immediately after maximal exercise in the non-supplement group. This result suggests that acute intake of RS have important role in inhibition of serum NO production during maximal exercise. Conclusively, This study suggest that acute intake of RS was not influence in body composition variables, but it was positive effect in ventilation threshold time, exhaustion time, maintenance of blood pressure and inhibition of serum NO production in maximal treadmill exercise.
