The purpose of this study was to analyze the effects of flossing band exercise on the range of motion and vertical jump for taekwondo demonstration athletes with ankle functional instability. The subjects of this study were 21 male Taekwondo Demonstration Team athletes enrolled at D University. They were divided into functional ankle instability group(FAIG, n=7), mild ankle instability group(MAIG, n=7), and ankle stability group(ASG, n=7). All groups performed a acute flossing band exercise program. The results of this study are as follows; dorsi flexion(p<.01), inversion(p<.01), eversion(p<.05) and vertical jump(p<.01) were significantly increased in the FAIG. Flossing band exercise of Taekwondo demonstration team with FAI increased joint range of motion and vertical jump. Therefore, it was confirmed that it could be an intervention that can improve performance and reduce the risk of ankle injury.

Purpose: This study aims to compare the effect on balance during core and ankle muscle strengthening exercises using the Thera-Band. Methods: 21 healthy college students were recruited. The participants were divided into a core strengthening group (CSG), an ankle strengthening group (ASG), and a non-exercise group (NEG). CSG and ASG were performed twice a week for a total of 4 weeks, and static and dynamic balance were measured before and after the intervention. The static balance were measured as stability index and weight distribution index using Tetrax^®. The dynamic balance was measured in each direction by the Y balance test. The Thera-Band intensity was increased after 2 weeks of exercise, and the exercise was subsequently performed. Results: Participants showed static balance with Tetrax^®, a significant difference was noted between normal eye closes and pillow with eye closes in ASG (p<0.05). In the case of dynamic balance with the Y balance test, a significant difference was observed in posterolateral direction (PL) and composite score (CS) between each group for the pre- and post-intervention differences (p<0.05). A significant difference was observed between PL and CS in CSG (p<0.05). Conclusion: These findings show that the progressive Thera-Band exercise had a positive effect on balance abilities. It was confirmed that core strengthening was effective for dynamic balance, and ankle strengthening was effective for static balance.

Purpose: This study examined the effects of an elastic band resistance exercise program on the body functions and Glycosylated hemoglobin (HbA1c) of elderly people with type 2 diabetes. Methods: Twenty-seven elderly patients with type 2 diabetes were enrolled in this study (exercise group 14, control group 13). The subjects in the exercise group participated in the program for 60 minutes a day, three times a week, for 12 weeks. All the subject's body functions, HbA1c were measured to compare the following: before the intervention, at the completion of the 12 weeks intervention, and eight weeks after the intervention. Results: Compared to the control group, the exercise group showed significant improvements in the 12 week and follow-up measurement after the intervention in body function, such as the strength of the upper and lower limbs, agility and limit of stability. The body functions of the exercise group improved as the period of intervention progressed. On the other hand, the HbA1c level at each follow-up measurement was similar in the two groups. Conclusion: The 12 week elastic band exercise program is recommended as an effective intervention for improving the body functions of elderly people with type 2 diabetes. Nevertheless, a combined intervention of steady exercise, diet therapy and drug therapy will be needed for further active prevention and management of type 2 diabetes.

Background: In patients with forward head posture (FHP), the head is positioned forward, causing increased tension in the muscles and structures of the head, neck, and shoulders. This can result in joint dysfunction that may lead to abnormal afferent information. The purpose of this study was to investigate the effect on foot pressure through the isometric hip abduction (IHA) bridge exercise using elastic bands in patients with FHP. Methods: Twenty patients with FHP were randomly assigned to a study group that applied joint mobilization, soft tissue mobilization, a deep neck flexor strengthening exercise, and the IHA bridge exercise using an elastic band. A control group was also constituted, and members were given joint mobilization, soft tissue mobilization therapies, and the deep neck flexor strengthening exercise. Ten patients were assigned to each group. The static foot pressure and dynamic foot pressure of each patient were measured before and after the intervention, and the interventions for each group were applied twice a week for 4 weeks. Results: Both the study group and the control group showed significant differences in static and dynamic foot pressure before and after the interventions (p<.05). There were no significant differences in foot pressure between the study and control groups. Conclusion: : The results of this study revealed that there were no significant differences between the group doing the IHA bridge exercise using the elastic band and the control group. However, the intervention methods applied to both the groups were effective in improving the body center control of FHP patients.

Muscle fatigue is characterized as a progressive increase in discomfort arising from the active muscle at moderate load levels are maintained. The median frequency is the most commonly used as a parameter to describe muscle fatigue. However, the estimate of the median frequency is difficult to indicate muscle fatigue because of its high standard deviation and instability. This paper investigates the power changes of the appropriate low frequency band as a fatigue parameter in EMG during isotonic exercise. To select the appropriate band, linear regression lines are employed to calculate the slopes and the coefficient of determination. Three females and seven males volunteered to participate in surface EMG recordings placed on the biceps brachii and each recording experiment continued until their exhaustion. The results of experiment shows that the power changes of the selected low frequency band (15~45 Hz) have linear slopes and high determinant coefficients. Therefore, this fatiguing parameter using the power changes of the low frequency band is valid to measure the state of muscular fatigue.

Purpose: This study examined the effects of aerobic exercise using a flex band on the improvement of physical functions & body image in breast cancer women undergoing radiation therapy after a mastectomy. Method: Women with breast cancer(n =26) were assigned to an experimental group(EG, n = 15) and control group(CG, n = 11). The E.G participated in an aerobic exercise program with a 60% to 80% intensity of maximal heart rate for 25 minutes during the main exercise, 3 times per week, for 6 weeks. The EG did not exercise regularly for 3 months before participating in this program. The CG received no exercise treatment during the research period. Data were analyzed using the $x^2-test$ and Mann-Whitney U test by the SPSS version 11.0 program at a 5% significant level. Results: Group analysis revealed that the EGwomen had significantly more improved cardio-pulmonary functions, ROM of the affected shoulder joint, and body image compared to the CG, Conclusion: Aerobic exercise using a flex band may be an effective rehabilitative measure for mastectomy women with respect to cardio-pulmonary functions, ROM, & body image. Further studies are recommended to study early rehabilitation programs within 10 days post-operatively.

Objective: The purpose of this study was to examine the effects of hip joint exercise using an elastic band on dynamic balance, agility, and flexibility in healthy subjects. Design: Randomized controlled trial. Methods: Thirty-five subjects (between 19 and 23 years) were randomly allocated to two groups: hip flexion exercise (HFE) group (n=17) and the hip abduction exercise (HAE) group (n=18). The HFE group participated in flexion exercise of the hip joint using an elastic band for 50 minutes a day, three days a week for four weeks, while the HAE group participated in abduction exercises of the hip joint using an elastic band for the same period. Dynamic balance was measured using the timed up and go (TUG) test, agility was measured with the standing long jump, and flexibility was measured using the Schober's test (5 cm, 10 cm). Results: The HFE group showed significant differences in the TUG test, standing long jump, and the Schober's test (10 cm) after training (p<0.05). The HAE group showed significant differences in the TUG test, standing long jump and the Schober's test (5 cm, 10 cm) after training (p<0.05). However, there was no significant difference between the HFE group and the HAE group. Conclusions: Flexion and abduction exercises of the hip joint using and elastic band increased dynamic balance, agility, and flexibility in healthy subjects. Additional research on hip joint exercises using an elastic band for improving dynamic balance, agility and flexibility are necessary.

In this research we would like to develop an exercise ECG signal analysis algorithm using the wavelet transform, which is possible to analyze the time and the frequency simultaneously. Wavelet transform has an advantage of dividing the nonstationary signals into the high frequency and low frequency band successively. Thus, it can separates the unnecessary noises from the frequency band of QRS complex and then using the selected frequency band we could detect the QRS complex and ST segment.

Purpose: The purpose of the study was to investigate the effects of visual feedback exercise (VFE), sandal exercise (SE), and thera-band exercise (TE) on people with functional ankle instability. Methods: The 45 study participants were divided into three groups of 15. In the VFE group, participants performed short-foot exercises using visual feedback; the SE group performed sandal exercises, and the TE group performed thera-band exercises. Over a period of 8 consecutive weeks, the experimental groups exercised for 15 minutes per session, four times per week. Balance was measured using the Biodex Balance System for dynamic balance ability (overall balance index [OBI], mediolateral balance index [MBI], and anterioposterior balance index [ABI]). Vibration threshold sense (VTS) was assessed using a vibratory sensory analyzer. Ankle muscular strength was measured using the Biodex 4 Pro. The main outcome measures were assessed at baseline and after 8 weeks of training. Results: Significant improvements in dynamic balance were noted in all three groups (p < 0.05). Significant improvements in VTS and muscular strength were also noted in the VFE and TE groups but not in the SE group (p < 0.05). Conclusion: Appropriate environmental and situational mediation may be of great clinical significance for patients suffering from chronic ankle instability. It is hoped that the findings will inform a program for prevention of ankle instability.
