Purpose : This study aimed to compare lung capacity measures (forced vital capacity; FVC, forced expiratory volume at 1 second; FEV1, and FEV1/FVC) and the activities of rectus femoris (RF) and gastrocnemius (GCM) muscles between young adults prescribed aerobic exercise combined with lower limb strength exercise (complex exercise) and those prescribed only aerobic exercise. Methods : We randomly divided 22 young adults into 2 groups: the complex exercise group that combined the leg strengthening and aerobic exercises (n = 11) and the aerobic-exercise-only group (n=11). Before the intervention, the FVC, FEV1, and FEV1/FVC values and the activities of RF and GCM muscles were measured. Measurements were in triplicates, and the average of the 3 measurements was used. The complex exercise group performed the treadmill exercise followed by squats and lunges, and the group performed only the treadmill exercise. Both groups were allocated the same time. Both groups performed the assigned exercise thrice a week for 3 weeks. After the intervention, the FVC, FEV1, and FEV1/FVC values and the activities of RF and GCM muscles were measured again. Results : The FVC and FEV1 values increased significantly in both groups after the intervention (p<.05). RF activity increased significantly after the intervention in the complex exercise group (p<.05), and the magnitude of change in RF activity after the intervention was significantly higher in the complex exercise group than in the aerobic-exercise-only group (p<.05). GCM activity also significantly increased after the intervention in both groups (p<.05). Conclusion : On the basis of our results, we recommend combining leg strengthening and aerobic exercise to improve leg muscle activity along with lung function.

[Purpose] While the anti-obesity effects of exercise and capsiate are well-observed individually, the effect of exercise with capsiate intake has not been systematically explored yet. Therefore, the purpose of this study is to investigate whether the anti-obesity effects of exercise training can be further enhanced by capsiate intake. [Methods] 8-week-old male mice were divided into 3 groups (n = 8 per group): sedentary group (SED; nontrained), exercise-trained group (EXE) and exercise-trained group with 10 mg/kg of capsiate intake (EXE+CAP). All mice were offered high-fat diet and water ad libitum. The mild-intensity treadmill training was conducted 5 times a week for 8 weeks. After 8 weeks, metabolism during exercise and abdominal fat weight were measured. [Results] Body weight and the rate of total abdominal fat were significantly less in EXE+CAP than in SED but not between EXE and SED. The average of respiratory exchange rate during exercise was significantly much lower in EXE+SED (p = 0.003) compared to the difference between EXE and SED (p = 0.025). Likewise, the fat oxidation during exercise was significantly much higher in EXE+SED (p = 0.016) compared to the difference between EXE and SED (p = 0.045). Then, the carbohydrate oxidation during exercise was significantly much lower in EXE+SED (p = 0.003) compared to the difference between EXE and SED (p = 0.028). [Conclusion] In conclusion, the anti-obesity functions of exercise training can be further enhanced by capsiate intake by increasing fat oxidation during exercise. Therefore, we suggest that capsiate could be a candidate supplement which can additively ameliorate obesity when combined with exercise.

B시 소재 기숙형특목고 K고교 학생 중에서 %fat이 30% 이상인 비만여고생 32명을 3그룹(운동군 2그룹, 통제군)으로 구분하여 1일 65분, 주 3회, 총 8주간 weight training (WT)과 step box training (SBT)을 조합한 복합운동을 A group은 WT 70-80%$RM{\times}3$ sets+SBT (RPE 11-13)${\times}1$ set로, B group은 70-80%$RM{\times}1$ sets+SBT (RPE 11-13)${\times}3$ set로 실시하여 신체조성(soft lean mass, %fat, WHR), HOMA-IR 및 HbA1c의 변화를 알아보았다. 자료처리는 집단 내는 paired t-test를, 집단 간은 측정 전 후의 변화율(%diff.)을 이용, one-way ANOVA (Duncan test)를 실시하여 다음과 같은 결론을 얻었다. 신체조성에서, 집단 내의 SLM은 운동군은 증가하였으나 통제군은 변화가 없었고, WHR은 A group은 감소하였으나 통제군은 증가하였다. %fat은 운동군 모두에서 감소하였으나 통제군은 증가하였다. 집단 간의 SLM은 A그룹이 B그룹과 통제군보다 더 크게 증가하였고, WHR은 A, B그룹이 통제군보다 더 크게 감소하였고, %fat은 A, B그룹이 통제군보다 더 크게 감소하였다. HOMA-IR은 집단 내에서는 운동군 모두 유의하게 감소하였으나 통제군은 유의하게 증가하였다. 집단 간 비교에서는 A, B그룹이 통제군보다 더 크게 감소하였다. HbA1c는 집단 내에서는 운동군 모두 유의하게 감소하였고 통제군은 변화가 없었다. 집단 간에서는 A그룹이 통제군보다 더 크게 감소하였다. 이러한 결과는 복합운동을 할 때 유산소운동 형태보다는 저항운동의 비율을 높여주는 것이 신체조성과 대사관련 인자 개선에 효과적이라는 것을 확인시켜 주는 것이며 본 연구의 결과로 볼 때 복합운동의 강도는 WT의 비중을 높게 설정하는 것이 바람직할 것으로 생각된다.

Background: Plyometric exercise is an exercise exerting forceful power in a brief period using isotonic activation. It is effective to improve reaction of muscle, agility, endurance and athletics performance. Weight training is an exericse improving muscular strength, endurance and respirating ability applying diversely in frequency and load of exercise Plyometric exercise and Weight training is to facilitate the athletics performance though improving the function of lower limb muscle, there is a difference that Plyometic jump squats is the way to improve agility and Weight training is the way to improve muscular strength. Therefore, it is necessary to know how this difference effects on athletics performance as measuring ankle, ROM, and jumping ability. Design: Randomized controlled trial. Method: This study was conducted with the voluntary participation of 40 university students, who were randomly assigned to jump squat and calf raise groups (n=20 per group). For each subject, we measured the range of motion of the ankle joint before and after exercise, as well as a standing broad jump and vertical jump test performance. We compared the performance indices before and after exercises using paired t-tests, and between groups using independent-samples t-tests. Conclusions: Both jump squat and calf raise exercises improved ankle joint dorsiflexion and plantar flexion, as well as standing broad jump and vertical jump height performance. However, there were no significant differences before versus after exercise, or between exercise types. Although jump squats and calf raises have different purposes, it is thought that, in combination, these exercises improve performance more effectively than either alone, and that such a combined exercise program improves the quality of training in both the general public and athletes in various sports.

PURPOSE: Forward head posture and turtle neck are common musculoskeletal disorders of the cervical vertebrae. The purpose of this study was to investigate the effects of combined exercise training and chiropractic on the grip strength and cervical muscle strength of subjects with forward head posture and turtle neck. METHODS: The subjects were divided into two groups: forward head posture (n=9) and turtle neck (n=9). Both groups performed combined exercise training and chiropractic. The subjects were instructed about the exercise training once a week. This training was performed for 30 minutes every day for 8 weeks, and the chiropractic was performed for 15 minutes once a week. The cervical muscle strength and grip strength were measured. Two-way repeated measured ANOVA was performed for statistical analysis. RESULTS: In changes to the left grip strength, the main effect over time was significant, but the interaction effect and the main effect in the groups were not significant. In changes to the right grip strength, no difference was found to be statistically significant. In changes to the cervical muscle strength, no difference was found to be statistically significant. CONCLUSION: The increases of grips strengths and cervical muscle strength in forward head posture group were greater than turtle neck group but there were not found to be statistically significant.

PURPOSE: This study aimed to provide basic clinical data by analyzing the impact of motion observation training and stretching exercises for improving postures on the neck alignment and balance of stroke patients to enable them to accurately recognize the correct exercise method. METHODS: After sampling 20 stroke patients who met the selection criteria, this study randomly assigned 10 people who were administered the stretching exercise with observation training to the experimental group and 10 who received only the stretching exercise intervention to the control group by drawing lots. Next, neck alignment and balance were pre-tested. All interventions were conducted for 30 minutes, 3 times a week for 4 weeks, and when all the interventions were completed after 4 weeks, neck alignment and balance were re-measured in the same way as the pre-test. RESULTS: The comparison of changes in neck alignment and balance within the experimental and control groups showed statistically significant differences in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). Between the groups, statistically significant differences were found in the craniovertebral angle, cranial rotation angle, and balance (p < .05) (p < .01). CONCLUSION: A statistically significant difference in neck alignment and balance was observed in the group that underwent stretching exercises combined with observational training and a statistically significant difference was found between the groups. Therefore, it is believed that observation training should be used in clinical practice to improve forward head posture and restore balance in stroke patients.

PURPOSE: The aim of this study was to determine how biofeedback training with Shaker exercise effects the activation of the cervical myocardial muscle in stroke with swallowing disorder. METHODS: From June 2018 to September 2018, 30 patients who were hospitalized at C hospital and K hospital in Daegu, and K hospital in Gumi were surveyed to meet the criteria for selection. The participants were classified into three groups, and Shaker exercise was applied three times a day, five times a week, for four weeks; visuoauditory biofeedback group (VABG), visual biofeedback group (VBG), and self-exercises group (SG). In addition, the suprahyoid muscle activity was performed three times (before intervention, after intervention, and after two weeks). RESULTS: The pre and post-test comparisons, revealed a significant difference between the three groups (p<.01); VABG had the highest suprahyoid muscle activity. The post-test and follow-up test produced similar results in, the three groups (p>.05). The mean comparison showed the smallest difference in VABG, indicating that muscle persistence was the best. CONCLUSION: Shaker exercise has an effect on suprahyoid muscle activation. Biofeedback training, which provides an input of multi-sensory information in swallowing disorder treatment is recommended because it has the greatest effect when combined with visuoauditory biofeedback.

Purpose : This study aimed to identify whether resistance exercise using elastic bands for six weeks can improve muscle strength, muscle tone, balance, and gait in patients with stroke. Methods : In total, 35 patients with stroke were randomly divided into three groups: resistance exercise using elastic band training combined with less affected side training group, more affected side training group, and both sides training group. Muscle strength, muscle tone, balance, and gait were assessed using a hand-held dynamometer, the modified Ashworth scale, the Berg Balance scale (BBS), and wireless 3-axis accelerometer, before and after training. Results : All three groups showed a significant increase in muscle strength of the lower extremity after training, and there was a significant difference among the groups. There was no change in muscle tone in all three groups. BBS scores increased significantly in all three groups after training, but these scores were not significantly different. The gait speed increased significantly in all three groups after the training, but the difference was not significant. The cadence increased significantly in Group 2 after training; however, there was no significant difference between Groups 1 and 3. There were no significant differences between the groups before and after the training. Step length increased significantly in Groups 2 and 3 after the training, but it was not significantly different in Group 1. After training, Groups 2 and 3 were significantly greater than Group 1 in the change in step length. Conclusion : The results show that resistance exercise using elastic bands can improve strength, balance, and gait in patients with chronic stroke. Especially, more affected side training was more effective in improving muscle strength than less affected side training. More affected side and both sides training are thought to be more effective than less affected side training to improve step length.
