Objective: The purpose of this study was to investigate the effects of neuromuscular training of ballet dancers with chronic ankle instability on ankle stability and posture controlability. Design: A randomized controlled trial. Methods: A total of Thirty-twoyoung female ballet dancers with chronic ankle instability have voluntarily participated in the study. The participants were randomized to the neuromuscular training group(n1=11), elastic resistance squat group(n2=11), and control group(n3=10). The intervention was applied to a total of 18 exercises per six weeks and conducted in each group for one hour a day, three times a week. All subjects were evaluated for Cumberland ankle instability tool(CAIT), static balance at before-after intervention. Results: In the comparison of the effects within the groups, the effect of the intervention on CAIT and posture control was significantly increased in the neuromuscular training group and elastic resistance squat group (p <0.05). In the comparison of the effects between the groups, the neuromuscular training group, and elastic resistance squat group were found to significantly increase more than the control group (p <0.05). The effect of ankle stability is similar in neuromuscular training and elastic resistance squat training, neuromuscular training is more effective in improving posture control rather than elastic resistance squat training. Conclusions: When planning a rehabilitation training program for a ballet dancer with chronic ankle instability, neuromuscular training can be applied as an intervention method to improve ankle stability and posture control ability.

The purpose of this study is to investigation the effects of functional compression clothing on muscle function by comparing the iEMG response of muscle during exercise according to the wearing of taping applied functional clothing. Six men in their twenties in Chungcheongnam-do were selected for the study. Resistance exercise was performed by cross-distributing the conditions of wearing and not wearing functional clothing. Resistance exercises for iEMG measurements are biceps curl, wrist curl, reverse wrist curl, kickback and push-up. iEMG measurement muscles were the biceps brachii, triceps brachii, extensor carpi ulnaris, flexor carpi radialis. During biceps curl exercise, the iEMG of triceps brachii, biceps brachii wearing condition was lower than the non-wearing condition. During kickback exercise, the iEMG of triceps brachii, extensor carpi ulnaris wearing condition was lower than the non-wearing condition. During reverse wrist curl exercise, the iEMG of extensor carpi ulnaris wearing condition was lower than the non-wearing condition. During wrist curl exercise, the iEMG of flexsor biceps brachii, carpi radialis wearing condition was lower than the non-wearing condition. During push-up exercise, the iEMG of triceps flexsor biceps brachii, carpi radialis, brachii, biceps brachii non-wearing condition was lower than the wearing condition.
Objective: The purpose of this study was to investigate the effect of high-intensity complex exercise program using whole-body vibration (WBV) and respiratory resistance on pain and dysfunction, psychosocial level, balance ability, and pulmonary function in low back pain (LBP) patients with high obesity. Design: A randomized controlled trial Methods: A total of 44 LBP patients withhigh obesity (body mass index, BMI≥30kg/m2) were randomly assigned to an experimental group (n=22) and a control group (n=22). Both groups underwent a lumbar stabilization exercise program. In addition, the experimental group implemented the high-intensity complex exercise program combined with WBV and respiratory resistance. In order to compare the effects depending on the intervention methods, numeric pain rating scale (NRPS), Roland-Morris disability questionnaire (RMDQ), fear-avoidance beliefs questionnaire (FABQ), balance ability, and pulmonary function were used for measurement. Results: Both groups showed significant differences in NRPS, RMDQ, FABQ, balance ability before and after intervention (p<0.05). In addition, the experimental groupshowed significant difference in the amount of change in RMDQ, balance ability and pulmonary function values than the control group (p<0.05). Conclusions: High-intensity complex exercise program using WBV and respiratory resistance has been proven to be an effective and clinically useful method to decrease dysfunction, increase balance ablilty, and pulmonary function for LBP patients with high obesity.
Purpose: This study was conducted to verify the effect of applying a pressure biofeedback unit on walking ability and knee joint function while performing knee joint extensor strengthening exercises using resistance exercise equipment in total knee replacement (TKR) patients. Methods: This study was conducted on twelve patients receiving rehabilitation treatment after being admitted to a rehabilitation hospital post-TKR. Of these, six were allocated to a feedback group with a pressure biofeedback unit, and the other 6 were allocated to a control group without a pressure biofeedback unit. The subjects performed an exercise program for 45 minutes per session, five times a week, for two weeks. Walking ability and knee joint function were evaluated and analyzed before and after exercise. Results: The feedback group showed significantly better improvements in walking speed, gait cycle, step length on the non-operation side, time on the foot on the operation side, K-WOMAC stiffness, and K-WOMAC function than the control group (p<0.05). Conclusion: When strengthening the knee joint extensor muscles using resistance exercise equipment in TKR patients, the provision of a pressure biofeedback unit was found to improve walking ability and knee joint function by inducing concentric-eccentric contraction of the knee joint extensor muscles. Therefore, the study shows that exercise based on the provision of a pressure biofeedback unit should be considered when strengthening knee joint extensor muscles to improve the walking ability and knee joint function of TKR patients in clinical practice.

Background: The bridge exercise prevents repeated damage to the tissues around the spine by reducing stimulus transmission to the ligaments and joint capsules, thereby alleviating back pain. It also contributes to strengthening the muscles of the lower extremities. Design: A Single Subject experience design. Methods: This study was conducted on 28 healthy adults in their 20s to 30s and conducted at St. Mary's Hospital in C City from May to July 2021. Four types of bridge exercise were performed in this study: the normal bridge exercise and bridge exercises with 0.5%, 1%, or 1.5% body weight resistance applied on the pelvis through manual resistance during the bridge exercise and to determine the effect of resistance applied in the bridge exercise on the activation of the trunk and lower extremities muscles. Results:This study showed that the muscle activity of the trunk and lower extremities improved significantly in response to stronger resistance when manual resistance equivalent to 0.5%, 1%, or 1.5% of body weight was applied during the bridge exercise compared to when the normal bridge exercise was performed. Conclusion: This study shows that manual resistance can be applied as an effective method of bridge exercise since muscle activity in the trunk and lower extremities increases when manual resistance causing isometric contraction is applied.
The purpose of this study is to offer basic data for the fall prevention by analyzing the kinematic difference between the lower limb joints and the lower extremities in elderly people's walking given the lower-limb resistance exercises. For this, three-dimensional image analysis was carried out by selecting 7 elderly women from over 70s to under 80 years old. To obtain the three-dimensional location coordinates in the lower limb joints and the lower extremities, it shot with 100Hz/s by using MCU(Qualisys, Sweden) camera. The shot image gained raw data on the location coordinates by using QTM(Qualisys, Sweden). As a result of calculating three-dimensional angle by using program of Matlab 6.5, the following conclusions were obtained. Flexion and extension in the thigh and the lower-leg extremities were indicated to be big in motion of flexion after exercising at E5. Foot segment indicated statistical difference while showing eversion at E4. Knee joints showed flexion at E4 after exercising. Ankle joints showed statistical difference while indicating motion in inversion at E3 and in eversion at E4(p<.05).

The present study evaluated the effects of fermented whey protein using kimchi lactic acid bacteria Lactobacillus casei DK211 on skeletal muscle mass, muscle strength, and physical performance in healthy middle-aged males performing regular resistance exercises. Effective protein supplementation and regular exercise are two important factors for improving muscle health. Therefore, in this study, the effects of consuming fermented whey protein twice a day were investigated and compared with that of non-fermented supplementation. Forty-eight males (average age 44.8) were randomly assigned to two groups: Fermented whey protein supplementation (FWPS) and non-fermented whey protein concentration supplementation (WPCS) groups. Each group ingested 37 g of FWPS or WPCS twice a day for eight weeks. Body composition, muscle strength, and physical performance were assessed pre- and post-intervention. Independent t-tests or chi-square tests for the categorical variables were performed for analyzing the observations. FWPS was effective in promoting the physical performance in dynamic balance measurement and muscle health, indicated through the increment in grip strength (left), upper arm circumference, and flat leg circumference from the baseline. However, similar improvements were not observed in the WPCS group. These results imply that whey protein fermented by L. casei DK211 is an effective protein supplement for enhancing muscle health in males performing regular resistance exercises.

Purpose: The purpose of this study is to examine the effects of a resistance band training program on body composition, physical fitness, and health promotion behavior in nursing students. Method: This study has a one-group pretest-posttest design to examine the change in body composition, physical fitness, and health-promoting lifestyle profile after participation in the resistance band training program. Training consisted of hands-based exercises using an elastic resistance band for ten weeks. Participants performed the resistance band training two days per week with a sports trainer, and 30 minutes self-training three days per week. The participants were 21 freshmen in nursing. Results: Mean age of the participants was 20.9 years, and 61.9% were not satisfied with their body shape. After the training program, muscle mass, muscular endurance, and balance of the body were significantly improved. In health promoting lifestyle profile, categories of physical activity, health responsibility, and stress management showed a significant increase. Conclusion: Results of this study suggested that exercising with a resistance band improved body composition, physical fitness, and health promoting behavior in the nursing students. We propose that resistance band training should be suitable for those who have the environment with limitation of time and space.

Background: The purpose of this study was to investigate how the resistive exercises with vibration stimuli could affect the strength of knee muscles and balance in patients with a history of reconstructive surgery. Methods: Thirty four subjects with anterior cruciate ligament reconstruction were randomly divided into 3 groups; Resistive exercises with vibration stimuli group (n=11), Resistive exercises (n=11) and control group (n=12). The paired t-test was used to show the variation before and after exercise in all three groups. One way ANOVA was used to separate the total variation between groups. Results: The results showed that there was significant improve in the strength of knee muscles in all three groups and resistive exercise with vibration stimuli he group showed a better result in all area than the other two groups. Comparisons of sway distances with open and closed eyes showed a statistically significant decrease before and after treatment in all three groups, there was no statistically significant difference between groups. There was a significant difference only in the sway distance with the eyes closed. Conclusions: Applying the resistive exercise with vibration stimuli as a therapeutic exercise program resulted in a positive effect to the functional activity not only in rapidly recovering the strength the weaken muscles and lost of balance ability, but also expecting an earlier return to daily life by advancing the date of the process for the functional activity.

Purpose : The purpose of this study is to find out which shoulder abduction angle among the three representative angles of lower trapezius strengthening exercises most effectively improves rounded shoulder posture. Methods : Thirty-one people with rounded shoulders, the subjects of this study, were selected. With the use of a random number table, group A was randomly assigned to a Y-type exercise, group B to a T-type exercise, and group C to an MPC exercise. In the prone position, both arms are abducted at the angles suggested for each group (145 °, 90 °, and 45 °, respectively), and the hands are holding dumbbells to assume a functional posture. With the start signal, the thumb raised the arm to the sky and the arm is raised to the level of the ear for 10 seconds and then returned to the original position. Each week, the strength required was increased by changing the resistance weight, number of times, and set, and the exercise was performed three times a week for a total of four weeks. Results : There was a significant difference in the change in shoulder height of each group after four weeks of exercise in comparison to the amount of change in height before and after exercise in all groups (p<.05). However, no significant difference was observed between all groups in the change in muscle activity of the lower trapezius muscle in each group following four weeks of exercise (p>.05). Conclusion : The results of this study showed that the three lower trapezius strengthening exercises have a positive effect on the improvement of rounded shoulders. In consideration of these results, it is therefore proposed that the various lower trapezius strengthening exercises be applied in parallel during physical therapy for patients with rounded shoulders in clinical practice.
