The purpose of this study was attempted to to identify the effects of combined resistance exercise and aerobic exercise course on health-related, and energy substrates. This study divided 24 healthy college students into the group of aerobic exercise after resistance exercise(n=8), the group of resistance exercise after aerobic exercise(n=8), and the control group(n=8) and thereby conducted a combined exercise program of different order for 12 weeks. Resistance exercise was conducted 4 times a week with the intensity of 60~70% of 1RM during the 1st through 8th week and the intensity of 70~80% of 1RM during the 9th through 12th week. Aerobic exercise was conducted 4 times a week with the intensity of 60~70% of maximum heart rate during the 1st through 8th week and the intensity of 70~80% of maximum heart rate during the 9th through 12th week. The results are as follows. 1. Changes of the health-related physical fitness In the changes of body composition through which we can know the degree of obesity. Body fat significantly decreased in both groups after 8 weeks and the decreased values were similar in each other group. However, the group of aerobic exercise after resistance exercise showed a significant increase of LBM after 8 weeks. We think that the method of aerobic exercise after resistance exercise was more effective than the other type of program. In the changes of physical fitness, flexibility, muscular endurance, muscular strength, and cardiovascular endurance of both exercised groups significantly increased compared to a control group. However, the increased values in both exercised groups showed similar results. 2. The changes of energy substrates There were no significant differences in glucose and free fatty acid being used by elements of energy substrates between the group of aerobic exercise after resistance exercise and the group of resistance exercise after aerobic exercise. Lactic acid, however, significantly decreased in the group of aerobic exercise after resistance exercise(0>12 weeks) and in the group of resistance exercise after aerobic exercise (0> 8, 12 weeks) compared to control group, respectively. Ultimately, this study provides evidence that the program which conducted aerobic exercise after resistance exercise is more effective than the program which conducted resistance exercise after aerobic exercise in the aspect of improving body composition. However, the both exercised groups showed a similar effect regardless of the order of execution of exercise in the elements of physical fitness and energy metabolism.

The purpose of this study is to investigate the effects of sequence of aerobic and resistance exercise on free fatty acids, epinephrine, testosterone, and IGF-1. 7 healthy adult males, the subjects of this research, performed both resistance exercise after aerobic exercise and aerobic exercise after resistance exercise. V?O2max of all the subjects was measured through treadmil test, and they performed aerobic exercise for 30 minutes using treadmil at the intensity of 65% of V?O2max. They also performed resistance exercise using weight machine. They did 80%1RM × 8~10 rep × 3set with one-minute rest between each set. Resistance after aerobic subjects had their blood sample all 4 times: before aerobic exercise, after aerobic exercise, after resistance exercise, and at 30-minute in the recovery; The aerobic after resistance subjects did their blood sample all 4 times: before resistance exercise, after resistance exercise, after aerobic exercise, and at 30-minute in the recovering period. Data were analyzed using SPSS PC 20.0. The Data were analyzed by One-way repeated ANOVA. Scheffe were used as a Post-Hoc test. Statistical significance level was a=.05. As a result of this study are as follows. First, the FFA are significant for resistance exercise after aerobic exercise group(p=.028). That is, FFA significantly increased after aerobic exercise and then decreased during 30-minute in the recovering stage; the coefficients on FFA are not significant for aerobic exercise after resistance exercise group(p=.415). Second, the coefficients of epinephrine are significant for resistance exercise after aerobic exercise group(p=.012); increased epinephrine resistance after exercise decreased during 30-minute in the recovering stage; the coefficients of epinephrine are not statistically significant for aerobic exercise after resistance exercise group(p=.112). Third, testosterone are significant for aerobic exercise after resistance exercise group(p=.004); increased testosterone due to resistance exercise decreased after aerobic exercise during 30-minute in the recovering stage. However, we can see that the coefficients of testosterone are not statistically significant in case of resistance exercise after aerobic exercise group(p=.074). Fourth, we can find that the coefficients on IGF-1 are statistically significant for both aerobic after resistance exercise(p=.000) and resistance exercise after aerobic groups(p=.000); the coefficients on IGF-1 are not significant after aerobic exercise, but they are significantly increased after resistance exercise for both. In conclusion, resistance exercise after aerobic exercise is likely to have a significant effect on FFA and epinephrine; aerobic exercise after resistance exercise look to affect testosterone and IGF-1. Accordingly, based on the research findings we can find that it is important to decide the order of exercise between aerobic exercise and resistance exercise depending on the purposes fat metabolism or protein synthesis of exercise.

The purpose of this study is to analyze the electrolyte such as blood ph, Na^(+), K^(+), Ca^(2+), Mg^(2+), etc on the each stage of pre-exercise, post-exercise, each 5 minute-recovery, 10 minute-recovery & 30 minute- recovery after exercise. For this experiment, 14 male students at the department of athletics in B Information Technology college in Busan was classified into each 7 exercise group and 7 non-exercise group, and after training them on the intensity of 60%HRmax of each subject 3 period a week for 8 consecutive weeks, the experiment was carried out with the same condition as training manner in treadmill. The results of this study are as follows. 1. Change of Blood Ph Through Aerobic Exercise In exercise group and non-exercise group, there was no particular change in Blood Ph between rest before training & the rest after 8 week- training according to t test. In case of exercise group, after 8 week-training blood ph value was significantly decreased, and at the 30minute-recovery after exercise, ph value was recovered to the degree of rest (p<.001). In case of non-exercise group, blood ph indicated significant change as the similar tendency showed in exercise group, at 10 minute-recovery after exercise, blood ph was recovered to the degree of rest. (p<.001). The change of ph by period between exercise group and non-exercise group was not significantly different. 2. Change of Blood Electrolyte Through Aerobic Exercise 1) Change of blood Na+ through aerobic exercise In exercise group and non-exercise group, the change of Na^(+) between the rest before training and the rest after training was not significantly different according to the result of t test. In case of exercise group, after performing 8 week-training, Na^(+) value was significantly increased, and at 10 minute-recovery after exercise, Na^(+) value began to recover into the value in rest, and after 30 minute-recovery after exercise, Na^(+) value was recovered into the degree of rest (p<.05). In case of the change of Na^(+) in non exercise group, after exercise, Na' value was significantly increased in comparison with rest period, and at 5 minutes after exercise, it was recovered into the degree of rest. (p<.01). The change of Na^(+) by period between exercise group and non-exercise group was not significantly different. 2) Change of Blood K^(+) through aerobic exercise In exercise group and non-exercise group, the change of K^(+) in rest before training and the rest after training was indicated that there was no significant difference according to t test. In case of exercise group, after 8 week training, K^(+) value was significantly increased, and at 5 minute-recovery after exercise, K^(+) value was recovered into the value in rest (p<.05). K^(+) in non-exercise group was not significantly changed. 3) Change of blood Ca^(+) through aerobic exercise In case of exercise group, the change of Ca^(+) in rest before training and the rest after training was not significantly different according to the result of t test. In case of non-exercise group, the change of Ca^(+) in rest before training and the rest after training was significantly different according to the result of t test (p<.05). In case of exercise group, after 8 week-training, Ca^(+) value was significantly increased, and at 5 minute- ecovery after exercise, Ca^(+) value began to recover into the degree of rest, and after 30 minute-recovery after exercise, Ca^(+) value was recovered to the degree of rest (p<.01). In case of the change of Ca^(+) in non-exercise group, after training, Ca^(+) value was significantly increased in comparison with rest period, and at 30 minute-recovery after exercise, Ca^(+) value was recovered into the degree of rest. (p<.001). In case of the change of Ca^(+) by period between exercise group and non-exercise group, after exercise and at 5 minutes recovery after exercise, the change of Ca^(+) in non-exercise group is higher than that of exercise group (p<.01). 4) Change of blood Mgt^(2+) through aerobic exercise In exercise group and non-exercise group, the change of Mg^(2+) between rest before training and the rest after training was not significantly different according to the result of t test. In both cases of exercise group and non-exercise group, after 8 week- raining, the change of Mg^(2+) was not significantly different. The change of Mg^(2+) by period between exercise group and non-exercise group, after exercise, the change of Mg^(2+) of non-exercise group was higher than that of exercise group (p<.01). 3. Correlation Between Blood Ph and Electolyte Through Aerobic Exercise In performance of 8 week aerobic training, the result of correlation analysis between blood ph and electrolyte in pre-exercise, post-exercise, each 5 minute, 10 minutes, 30 minutes-recovery after exercise showed that in case of Na^(+), K^(+), Mg^(2+) did not have significant correlation, but in case of Ca^(2+), it showed significant negative correlation in pre-exercise and at 10 minute- recovery after exercise. (p<.05).

Purpose Most studies on nonalcoholic fatty liver disease (NAFLD) focused on the subject in middle-aged or elderly adults. However, the negative effects of temporary high-fat diet may differ according to age, and the effective intensity of exercise for alleviation of NAFLD may also differ according to age. The purpose of this study was to examine the changes in hepatic steatosis caused by temporary high-fat diet and to analyze the effect of aerobic exercise intensity on NAFLD in young-aged mice. Methods 4 weeks old male C57BL/6 mice were classified into a normal diet group (CO, n = 8) or a high-fat diet group (HF, n = 24). HF group consumed a high-fat diet for 8 weeks. After then, HF group was randomly assigned to the HF+non-exercise group (HF, n = 8), HF+low-intensity aerobic exercise group (HFLE, n = 8), and HF+high-intensity aerobic exercise group (HFHE, n = 8). The mice in the exercise group conducted aerobic exercise 5 times a week for 8 weeks at their exercise intensity. Results After 8 weeks of high-fat diet, body weight, liver weight, liver TG, and liver lipid droplets in the HF group were significantly increased. However, although fat synthesis-related factors were still high, regular exercise was effective in relieving fatty liver by increasing carnitine palmitoyl transferase-1 and phospho AMP-activated protein kinase proteins. In addition, high-intensity aerobic exercise effectively reduced liver TG and lipid droplets compared to low-intensity aerobic exercise. Conclusion High-intensity aerobic exercise was more effective in alleviating NAFLD than low-intensity exercise by decreasing the liver weight and liver TG. Therefore, high-intensity exercise can be recommended as an effective exercise for alleviating NAFLD in childhood. 연구목적 NAFLD에 관한 대부분의 연구는 중년 또는 노년 등의 성인에게 초점을 맞추고 있다. 하지만 일시적인 고지방 식이섭취로 인한 부정적인 효과는 연령에 따라 다르게 나타날 수 있으며, 또한 NAFLD를 완화하기 위한 효과적인 운동 강도 역시 연령에 따라 다를 수 있다. 본 연구에서는 아동기 쥐의 일시적인 고지방 식이 섭취로 인한 간 지방증의 변화를 살펴보고, 유산소 운동 강도가 NAFLD에 미치는 영향을 분석하고자 하였다. 연구방법 4주령의 수컷 C57BL/6 쥐를 분양받아, 일반식이 섭취군 (CO, n = 8)과 고지방식이 섭취군 (HF, n = 24)으로 분류하였다. HF군은 8주간의 고지방 식이를 섭취하였으며, 그 후, HF군의 쥐들은 무작위로 HF+비운동군(HF, n = 8), HF+저강도 유산소운동군(HFLE, n = 8), 그리고 HF+고강도 유산소운동군(HFHE, n = 8)으로 분류하였다. 운동군의 쥐들은 자신의 운동강도로 8주간 주 5회의 유산소 운동을 실시하였다. 결과 고지방식이 8주 후 HF 그룹의 체중, 간 무게, 간 TG 및 간 지방 방울이 유의하게 증가했다. 그러나 규칙적인 운동은 지방합성 관련인자를 유의하게 증가시켰지만, carnitine palmitoyl transferase-1과 phospho AMP-activated protein kinase 단백질을 증가시킴으로써, 지방간 완화에 효과적인 것으로 나타났다. 또한, 고강도 운동은 저강도 운동에 비해 간 TG 및 지방 방울 감소에 효과적인 것으로 나타났다. 결론 고강도 유산소 운동은 저강도 운동보다 간의 무게와 간 TG를 현저하게 감소시킴으로써 NAFLD 완화에 더 효과적이었다. 따라서 아동기에 NAFLD를 완화시키는 효과적인 운동으로 고강도 운동을 권장할 수 있음을 제안한다.

Purpose: In this study is to examine changes in metabolic risk factors (TC, TG, LDL-C, HDL-C, BMI, fasting blood glucose, fasting insulin and HOMA-IR) and Myokines (Irisin and FGF-21) according to exercise intensity through long-term aerobic exercise for obese men. Method: Subjects of the study calculated individual VO2max by exercise load test, A: low-intensity aerobic exercise group, VO2R 40% (low-intensity exercise group; LIEG), B: medium-intensity aerobic exercise group, VO2 60% (middle-intensity exercise group; MIEG), C: high-intensity aerobic exercise group, VO2R 80% (high-intensity exercise group; HIEG), D: control group (CG). For aerobic exercise, the treadmill speed was adjusted to maintain about ±3 of the target heart rate until the time spent 300kcal at the corresponding exercise intensity with the individual target heart rate by wearing a wireless heart rate device. In consideration of exercise adaptability, exercise time and intensity were recalculated after 6 weeks and applied for 12 weeks, 3 times a week. Results: TG, LDL-C, HDL-C, BMI, Glucose, Insulin, and HOMA-IR showed significant decreases in LEDG and HIEG, excluding TC. In MIEG of exercise treatment, the duration of exercise treatment showed a greater reduction after 12 weeks than after 6 weeks. In addition, changes in Irisin and FGF-21 also showed the most effective increase in MIEG, and the improvement of myokine was higher after 12 weeks of aerobic exercise. Conclusion: Even with the same exercise in the exercise metabolism of obese people, 12 weeks of moderate-intensity aerobic exercise is considered the most effective exercise treatment for myokine expression and lipid relief by accelerating the change of metabolic risk factors and the browning of white fat.

The purpose of this study is to investigate the effect of aerobic and combined exercise on GH in elementary school students. Aerobic exercise was performed with a treadmill and a step box. The exercise intensity was within the range of HRR 55 ~ 70%. The combined exercise was performed in the same way as aerobic exercise and anaerobic exercise. The anaerobic exercise was performed three times a week for 60 minutes using an elastic band. GH (growth hormone) was measured before and after exercise. Data analysis of this study was analyzed by ANCOVA using SPSS 18.0 and significance level was conducted at .05. The results obtained through the above research procedure are as followsFirst, in the change of GH, the aerobic exercise group was decreased but not significant, and the combined exercise group was increased but not significant. There was no significant difference between the two groups. Second, in the changes of IGF-1, both the group of aerobic exercise and the group of complex exercise increased meaningfully and in the contrast between the two groups showed that the group of complex exercise increased more meaningfully than group of aerobic exercise did. Third, in the changes of the blood lipids, TG and TC decreased meaningfully in both groups, but the contrast between the two groups did not show meaningful change. In the change of LDL-C, both groups of aerobic exercise and complex exercise increased but not meaningfully, and a meaningful change between two groups was not found. In the change of HDL-C, the group of aerobic exercise increased but was not meaningful, and the group of complex exercise decreased but was not meaningful. And a meaningful change between the two groups was not found. In conclusion, the aerobic exercise and complex exercise gave a positive influence to students by increasing the students' IGF-1 and by decreasing the level of TG and TC. The difference between aerobic exercise and complex exercise is that complex exercise positively changes the level of IGF-1. 본 연구의 목적은 유산소 운동과 복합운동이 초등학생의 GH에 미치는 영향을 규명하는 것이다. 유산소운동은 트레드밀과 스텝박스를 이용하였으며 운동강도는 HRR 55~70% 범위 내에서 실시하였다. 복합운동은 유산소 운동, 무산소운동을 병행하여 실시하였고 유산소 운동은 유산소 운동군과 동일하게 실시하고 무산소 운동은 탄성밴드를 이용하여 12주간 주 3회, 60분 실시하였다. 운동 전·후 측정항목은 GH(성장호르몬)을 측정하였다. 본 연구의 자료 분석은 SPSS 18.0을 이용하여 ANCOVA로 분석하였으며 유의수준은 .05에서 실시하였다. 이상의 연구절차를 통해 얻은 결과는 다음과 같다첫째, GH의 변화에서 유산소 운동군은 감소하였으나 유의하지 않았고 복합운동군은 증가하였으나 유의하지 않았다. 두 집단간의 차이에서도 유의한 변화는 나타나지 않았다. 둘째, IGF-1의 변화에서 유산소 운동군과 복합운동군 모두 유의하게 증가하였으며 두 집단 간의 차이에서는 복합운동군이 유산소 운동군보다 유의하게 증가한 것으로 나타났다. 셋째, 혈중지질의 변화에서 TG, TC는 유산소 운동군과 복합운동군 모두 유의하게 감소하였으며 두 집단 간의 차이에서는 유의한 변화가 나타나지 않았다. LDL-C의 변화에서는 유산소 운동군과 복합운동군 모두 증가하였으나 유의하지 않았으며 두 집단 간에도 유의한 변화도 나타나지 않았다. HDL-C의 변화에서는 유산소 운동군은 증가하였으나 유의하지 않았으며 복합운동군은 감소하였으나 유의하지 않았다. 두 집단 간에도 유의한 변화는 나타나지 않았다. 결론적으로, 유산소 운동과 복합운동은 초등학생의 IGF-1을 증가시키고 TG와 TC의 수준을 감소시켜 각각 긍정적인 영향을 주었다. 유산소 운동과 복합운동의 차이는 복합운동이 유산소 운동보다 IGF-1의 수준에 긍정적인 변화를 준다는 것을 알 수 있었다.

The purpose of this study is to investigate the effect of aerobic exercise on health related fitness and physical self-efficacy in obese elementary school boys. In order to achieve this purpose, 22 students who wish to participate in the aerobic exercise program (running program) were selected among 5th and 6th grade students. Students were divided into two groups(exercise group: 11 boys, control group: 11 boys). The exercise group carried out aerobic exercise program during their spare time in the morning, three times a week, while the control group spent their normal daily life. Health related fitness and physical self-efficacy were measured by t-test between exercise group and control group after 12 week aerobic exercise. The results are as in the following. The students who participated in the aerobic exercise program have changed significant difference statistically on their muscular endurance, cardiopulmonary endurance and flexibility. Body mass index (BMI) showed significant difference in the exercise group pre and post 12 week exercise training. Self-confidence and self control-efficacy showed significant differences statistically pre and post in the exercise group. Attitude towards task difficulty preference showed significant difference statistically before and after in the exercise group. In conclusion, the running exercise as a aerobic exercise program in elementary school obese boys had significant differences statistically on muscular endurance, cardiopulmonary endurance and flexibility and self-confidence, self control-efficacy, attitude towards task difficulty preference. It is considered that the aerobic exercise is required for obese boy s health related physical fitness and physical self-efficacy.
