The purpose of this study was to investigate the effects of meditation music with lumbar stabilization exercise on balance, concentration and muscle activation. Participants are divided into Group A and Group B. Group A listened to meditation music while doing 4 sets of lumbar stabilization exercise. Group B did not listen to meditation music while doing 4 sets of lumbar stabilization exercise. Surface EMG data was obtained rectus abdominis, external oblique, erector spinae, multifidus muscle during lumbar stabilization exercise. To examine the effect of before-after experiment for concentration and balance, paired t-test was adopted. Changes in EMG data of each muscles were analyzed by independence t-test. There were statistically significant increasing at concentration level and balance level in Group A. But significant difference was not shown in muscle activation. The clinical effect of the meditation music with lumbar stabilization exercise was investigated in this study with more excellent results in concentration and balance. In conclusion, these results suggest that meditation music and lumbar stabilization exercise may be useful in elderly people.

The purpose of this study was to compare the muscle activities of the thoracic extensor(TE) and lumbar extensor(LE) during trunk lift (TL) exercise according to exercise position. Seventeen healthy subjects with no medial history of back pain were recruited for this study. Subjects performed the TL exercise in prone, quadruped and heel-sitting positions. The activities of the TE and LE were measured using surface electromyography during TL exercise in each exercise position. A one-way repeated-measures analysis of variance (ANOVA) was used to compare the normalized muscle activities of the TE and LE and the TE/LE ratio. The results showed that there was not significant effect of exercise position on the muscle activities of TE(p>.05). However, there was significant effect of exercise position on the muscle activities of LE and the TE/LE ratio(p>.05). Post hoc pair-wise comparisons with Bonferroni correction showed that both muscle activities of LE and TE/LE ratio in prone position were significantly different in those in heel-sitting and quadruped positions, during TL exercise, respectively. The TE/LE ratio was the greatest for TL exercise in heel-sitting position. Therefore, for selective activation of the TE muscle, we recommend performing the TL exercise in heel-sitting or quadruped position.

Reductions in strength and range of motion in older persons have been associated with decreased functional mobility and risk of falls. The purpose of this research was to investigate the effect of intensive dynamic balance exercise (DBE) during 8 weeks on onset time of medial gastrocnemius and tibialis anterior muscle contraction after perturbation in older women. Thirty subjects were randomly assigned into DBE group or control group. The DBE group participated in 50 minutes 3 days a week for 8 weeks. Surface electromyography (EMG) activity was recorded from the medial gastrocnemius and tibialis anterior muscles of left side. Outcome data were collected both groups at the pre-exercise and post-exercise. Independent t-test and paired t-test were used to determine the statistical difference. Results showed that the passive range of motion and functional reach test were significantly increased in the DBE group than the control group at the post-exercise (p<.05). The onset time of both muscles and discrepancy of onset time significantly reduced in the DBE group than the control group at the post-exercise (p<.05). The onset time of both muscles were significantly reduced in the post-exercise than the pre-exercise in the DBE group (p<.05). The discrepancy of onset time in the DBE group was significantly reduced in the post-exercise than the pre-exercise (p<.05). These findings suggest that intensive dynamic balance exercise for the eight weeks was effective in improving the postural control with older persons.

This study was designed to investigate the effect of Gibson's smile exercise. The author took the smile photographs of 35 university students who appeared unnatural smiles though they had good dentition or well restored state of their teeth. The author explained Gibson's smile exercise and they trained their perioral muscles during 4 weeks at home. The smile photographs were taken at regular intervals, before the smile exercise, 2 weeks after and 4 weeks after the smile exercise. And then, esthetic smile scores were estimated by 10 appraisers who were dentists. Some questionares were taken aftersmile exercise. And acquired scores were analized statistically using the SPSS program. The results obtained were as follows. 1. The smile scores of 2 weeks after and 4 weeks after the smile exercise were higher than before the smile exercise. 2. The smile scores of 4 weeks after the smile exercise were higher than 2 weeks after the smile exercise. 3. The smile scores of the group interested in smiles were higher than the group not interested in smiles at 2 weeks after and 4 weeks after the smile exercise, but before the smile exercise there was no difference between two groups.

Objective: The community has implemented a variety of exercise programs for the elderly population. However, studies comparing changes in the cardiovascular system through body composition and blood analysis after applying aqua aerobic exercise are insufficient. The purpose of this study was to investigate the effect of a 12 weeks aqua exercise on body composition and cardiovascular index in elderly women. Design: Non-equivalence pre-post design. Methods: Thirty elderly women were assigned to aquarobic group(n=15) and control group(n=15). The aquarobic exercise was 60 minutes per every session, 2times per week, for 12weeks. Weight, skeletal muscle mass, body fat percentage, total cholesterol, triglyceride, HDL cholesterol, and LDL cholesterol were measured before and after the exercise program. Paired and independent t-tests were performed using SPSS program. Results: The result showed was weight(p<0.05), body fat percentage(p<0.05), total cholesterol(p<0.05), triglyceride(p<0.05), HDL cholesterol(p<0.05), and LDL cholesterol(p<0.05) were significantly decreased and skeletal muscle mass(p>0.05) was not significantly increased after aquatic exercise program. Conclusions: According to the study result, aqua exercise program made a positive effect in the improvement of obesity and cardiovascular function in elderly women. Therefore, we suggest that you actively consider implementing the Aquarobic exercise program when operating the community health promotion program in the future. In addition, in future studies, comparative studies according to various ages and genders and studies on the effects of aqua aerobic exercise as a community exercise program for chronically illness patients are needed.

Objective: This study was aimed at investigating the effects of lumbar stabilization exercise according to correct verbal instructions in pain and muscle strengthening of the low back pain patients. Design: A randomized controlled trial. Methods: Twenty subjects with low back pain were selected. They were randomly assigned to one of two groups (10 in each group): namely the lumbar stabilization exercise and lumbar stabilization exercise according to the correct verbal instructions group. The lumbar stabilization exercise group performed lumbar stabilization exercises for 6 weeks (5 times a week). The lumbar stabilization exercise according to correct verbal instructions group performed lumbar stabilization exercise according to correct verbal instructions for 6 weeks (5 times a week). We measured pain, muscle power, proprioception, and body balance before and after exercise by using visual analog scale (VAS), digital handheld dynanometer, Joint repositioning error, time up and go test respectively. Results: We found statistically significant differences in pain, muscle power, proprioception, and body balance in lumbar stabilization exercise and lumbar stabilization exercise according to correct verbal instructions group, before and after (p<0.05). Conclusions: We confirmed the effect of lumbar stabilization exercise according to correct verbal instructions. Thus we thought these results could be used as basic data and reference for low back pain. But we need more study effect of correct verbal instructions on other exercises.

The purpose of this study was to investigate the effect of the intensity of warm-up exercise on the physiological response and exercise performance during resistance exercise. For this purpose, 8 male college students with at least 1 year of experience in resistance movement were selected. The warm-up condition was set to NON condition (preparatory exercise not performed), 3 set condition, 6 set condition, and 9 set condition, and the intensity was different for each set. After warm-up, 75% 1RM of main exercise was performed, and blood pressure and heart rate were measured immediately after exercise to measure RPP. The number of repetitions and total work for each condition were measured as the number of repetitions and momentum during the main exercise. The measured data were analyzed by repeated measures two-way ANOVA. As a result, although there was no difference in Rate Pressure Product according to the warm-up conditions, the number of repetitions and total amount of exercise showed the highest in the 3-set condition. Therefore, it is thought that the number and intensity of warm-up exercises should be set appropriately during resistance exercise, and warm-up of 3 sets or more during resistance exercise is thought to decrease exercise performance.

The purpose of this study was to verify the validation of effect on improvement of muscle strength unbalance according to exercise load deviation during rowing exercise. We performed evaluation of muscular activity and joint torque before the test. We recruited twenty subjects who one side's muscle strength is bigger in more 20% than other side. Subjects divided two groups. One is dominant left side and the other was dominant right side. Subjects performed rowing exercise in electric load deviation rowing equipment (Robo.gym, Humonic Co., Ltd., Daegu, Korea). Exercise performed four sets a day including 25 times a set, and three days a week. Measurements consist of evaluation of muscular activity and joint torque. Exercise load deviation adapted that different value of muscle strength in both arms multiplied 1RM% and added 1RM 50%. The results in adapted load deviation showed that the differences of maximal peak torque in 22.75% were getting increase significantly during exercise in 5.72%. This interpreted that rowing exercise with loading deviation types could provide muscle strength and muscular endurance exercise in same time for balance. Our study found out that loading deviation could provide muscle strength and muscular endurance exercise for improving muscle unbalance.
