Purpose: This study aimed to determine the appropriate stimulus strength that could result in a positive effect on the ankle joint spasticity when patients with chronic stroke performed whole body vibration (WBV) exercise. Methods: Among 72 patients who were diagnosed with stroke at least 6 months ago, those able to perform a half squat pose with ambulation issues due to ankle joint spasticity (modified Ashworth scale, $MAS{\geq}2$) were included for analysis. Individuals participated in four different frequencies of vertical WBV exercise; 0 Hz, 10 Hz, 20 Hz, and 30 Hz. Vibration amplitude was 3-4 mm and 5 minutes WBV exercise was performed at each frequency, followed by a measurement after 2-minute rest. We assigned 18 individuals to each frequency and asked them to participate in the WBV exercise once every 3 weeks. The level of spasticity was evaluated by visual analogue scale (VAS) for self-assessment. The myoton PRO was utilized to objectively evaluate the level of spasticity and check the muscle tone and stiffness. Results: Participants showed 0 Hz VAS was a significant difference between 20 Hz application conditions (p<0.05). Muscle tone was significantly different at 0 Hz between 20 Hz, and 30 Hz (p<0.05), significantly difference at 10 Hz between 30 Hz (p<0.05). Muscle stiffness significantly difference at 0 Hz between 20 Hz, and 30 Hz (p<0.05), significantly difference at 10 Hz between 20 Hz, and 30 Hz (p<0.05). Conclusion: Findings of this study show that the frequency of more than 20 Hz was effective in improving the ambulatory ability in patients with chronic stroke. Currently, the effective WBV protocol is limited. Hence, this study was designed to suggest an effective WBV protocol to improve neuromodulation ability for chronic stroke patients.

Many studies have shown that the initial median frequency (MDF) and slope correlate with the muscle fiber composition. This study tested the hypothesis that the initial MDF and slope are fixed, regardless of the interval at which data are collected. MDF data using moving fast Fourier transformation of EMG signals, following local fatigue induced by isotonic exercise, were obtained. An inverse FFT was used to eliminate noise, and characteristic decreasing regression lines were obtained. The regression analysis was done in three different periods, the first one third, first half, and full period, looking at variance in the initial MDF, slope, and fatigue index. Data from surface EMG signals during fatiguing isotonic exercise of the biceps brachii and vastus lateralis in 20 normal subjects were collected. The loads tested were 30% and 60% maximum voluntary contraction (MVC) in the biceps brachii and 40% and 80% MVC in the vastus lateralis. The rate was 25 flexions per minute. There were no significant differences in the initial MDF or slope during the early or full periods of the regression, but there was a significant difference in the fatigue index. Therefore, to observe the change in the initial MDF and slope of the MDF regression line during isotonic exercise, this study suggest that only the early interval need to be observed.

The aim of this study was to determine the association between, smoking, exercise, sex, and dietary carotenoids ($\alpha$-carotene, $\beta$-carotene, $\beta$-cryptoxanthin, lutein + zeaxanthin, lycopne) intake in Korean middle-aged adults. Food-frequency questionnaire were analyzed from 304 healthy adults (115 men, 189 women) aged 20 - 59. The self-administered questionnaire contained subject s habitual diet and alcohol intake were the previous 3 months. Data on frequency of 102 foods, including vegetables, fruits, beverages and legumes were analyzed. Total dietary carotenoids intake were 27.13 $\pm$ 3.09 mg/d for men and 26.71$\pm$ 2.82 mg/d for women. It was found that smoking had no significant contribution to the dietary intake of carotenoids. Among other lifestyle factors that had significant correlation was the amount of exercise time. The increases in exercise time was associated with increase in carotenoids intake (r= 0.121, p : 0.04). The major contributors of $\alpha$-carotene and $\beta$-carotene were carrots consumed as single-food item or carrot juice. Lutein and Zeaxanthin intake mainly came from spinach and most lycopene intake was derived from tomato products not fresh tomatoes. Persimmon was the major contributor of $\beta$-cryptoxanthin. These findings provide valuable information on understanding the unique pattern of dietary intake of Korean, which might help identify the risks for developing various diseases.

The modern convenient life formed by industrial development becomes lack of exercise and takes an interest in diet. Specially, professional walking shoes is developed as people take an interest in jogging, Those shoes, professional walking shoes or Dietshoes, increase exercise effects by change of heel types. Therefore, this study investigated motility effects by EMG experiment in order to measure Muscle Activities (MA) while wearing diet shoes (backless). Experiment was conducted by EMG measurement, from calf (gastrocnemius muscle), thigh (vastus muscle) and waist (erector spinae muscle), of 12 high school students. Exercise effects between the two shoes were analyzed by EMG (MF; Median Frequency, MPF; Mean Power Frequency, ZCR; Zero Crossing Rate). Results showed that the Dietshoes(MF: 48.21Hz, MPF: 65.0Hz, ZCR: 100.6Hz) had larger EMG value than that of Normal shoes(MF: 40.47Hz, MPF: 58.04Hz, ZCR: 82.09Hz). Also, in MA, the highest activities are showed in the calf, the second one is in waist, and last one is in thigh during gate. ANOVA between shoes in measurement parts showed significant effects in MF (gastrocnemius: p-value=.022, vastus laterals: p-value=.037, erector spinae: p-value=.082), MPF (gastrocnemius: p-value=.032, vastus laterals: p-value=.046, erector spinae: p-value=.090), and ZCR (gastrocnemius: p-value=.000, vastus laterals: p-value=.004, erector spinae: p-value=.134). And MA of Dietshoes is higher than that of Normal shoes, and decreasing rate of MA in Dietshoes is less than that of Normal shoes. Thus, this study validates exercise effects of Dietshoes.

The daily food intake and its related factors of the elderly(aged over 60) living in Incheon were compared. Self administered questionnaires were collected from 418 elderly. Statistical data analysis was completed using a SPSS v. 10.0 program. The results are summarized as follows: About 70% of elderly took grains and starch foods relatively high. The daily intakes of them was significantly influenced by ages of elderly, self-perceived health status, degree of drinking, meal regularity and nutritional balance of meals. More than 80% of elderly responded to take the food group of meat, fish and eggs poorly. Among various factors, the residence type and snack intake frequency influenced the daily intake of those foods statistically. A half of elderly took the vegetables and fruits everyday more than average. The daily consumption of vegetables and fruits was significantly influenced by sex, ages, exercise, snack intake frequency and preference of spices. Most elderly consumed fewer servings of milk and dairy products. About 60% of them did not take milk and dairy products daily. The daily contribution of those foods was significantly influenced by residence and exercise. 45.5% of elderly took oils and sugars more than average everyday which was influenced significantly by residence, exercise, snack intake frequency and meal regularity. In conclusion, the important influencing factors on the daily food intakes of elderly might be related to ages, residence, family, smoking, drinking, exercise, snack intake frequency and meal regularity. Therefore, a situation-oriented and practically organized nutrition education and ingestion support programs which consider the elderlies' socioeconomic status may help to improve the daily food intake of elderly in Incheon area.

The purpose of this study was to determine the effects of transcutaneous electrical nerve stimulation(TENS) on delayed onset muscle soreness(DOMS). Twenty males performed eccentric exercise of the elbow flexor. Subjects were randomly assigned to one of three groups: 1) a group ($n_1$=7) that received low frequency TENS (7 Hz), 2) a group ($n_2$=7) that received high frequency TENS (500 Hz), 3) a control group ($n_3$=6) that received no treatment. DOMS was induced in a standardised fashion in the non-dominant elbow flexor of all subjects by repeated eccentric exercise. Treatments were applied immediately following exercise and again at 24 hours and at 48 hours after. Subjects attended on three consecutive days for treatment and measurement of elbow flexion, extension and resting angle(universal goniometer), and pain(Visual Analogue Scale; VAS) on a daily basis. Measurements were taken after treatment. Analysis of results using repeated measures analysis of variance(ANOVA) and post hoc tests were as follows: 1) there were between groups differences in pain value at 48 hours after (p<0.05), 2) one-way ANOVA with repeated measurement for pain, resting angle, flexion angle and extension angle revealed significant differences within low frequency TENS group, 3) one-way ANOVA with repeated measurement for flexion angle revealed significant difference within high frequency TENS group.

The purpose of this study was to analyze the changes in muscle fatigue by using electromyography (EMG) measurements of the median frequency of shoulder muscles of patients who underwent rotator cuff repair, and to provide basic data for efficient exercise methods during rehabilitation after the repair. In the study, 24 male and 8 female patients who underwent rotator cuff repair performed continuous passive shoulder joint motion for 3 weeks and the median frequency of their shoulder muscles before and after the repair were compared using measurements by EMG. The infraspinatus, supraspinatus, and serratus anterior muscles showed significant differences in the changes in the median frequency before and after the repair. Significant differences were also found in the median frequency of the three muscles both before and after the repair. Additionally, the middle deltoid muscle had a lower median frequency than the supraspinatus muscle before the repair and the infraspinatus muscle had a lower median frequency than the middle deltoid muscle after the repair. It is expected that these results will serve as important data in developing rehabilitation exercise programs for the infraspinatus, supraspinatus, and serratus anterior muscles by compensating the middle deltoid muscle with the lowest muscle fatigue after the rotator cuff repair erase.

In rehabilitation programs involving muscle re-education and endurance exercise, it is necessary to confirm when fatigue occurs. It is also necessary to quantify fatigue, to confirm whether the muscle has been exercised sufficiently. In general, as fatigue occurs, the force-generating ability of the muscle is reduced. If the median frequency (MDF) obtained from electromyogram (EMG) power spectrum is correlated highly with work, then the timing and degree of fatigue may be confirmed. This study examined the relationship between work and MDF obtained from the EMG power spectrum during repetitive isokinetic exercise. Surface EMG signals were collected from biceps brachii and vastus lateralis of 52 normal subjects (26 males, 26 females) at $120^{\circ}/sec$ and $60^{\circ}/sec$ while performing an isokinetic exercise. The exercise was finished at 25% of peak work. MDF data was obtained using a moving fast Fourier transformation (FFT), and random noise was removed using the inverse FFT, then a new MDF data was obtained from the main signal. There was a high correlation between work and MDF during repetitiv isokinetic exercise in the biceps brachii and vastus lateralis of males and the biceps brachii of females (r=.50~.77). However, there was a low correlation between work and MDF in the vastus lateralis of females (r=.06~.19).
