The aims of this study were to investigate the correlation between the electromyographic (EMG) activity of the abductor hallucis (AbdH) and the amount of pressure measured by a pinch gauge (PG), and to compare the EMG activity of AbdH and the pressure measured by the PG during short foot (SF) exercise in subjects with pes planus and in subjects with a neutral foot alignment. Fourteen subjects were recruited for this study (pes planus group=7; neutral foot alignment group=7). A surface EMG was used to collect AbdH activity, and a PG was positioned under the first metatarsophalangeal joint to measure the pressure produced by the first metatarsal head during the SF exercise. The AbdH activity and the pressure measured by the PG showed a positive good correlation (r=.80, p<.05). The EMG activity of the AbdH and the pressure measured by the PG were significantly lower for subjects with pes planus than for subjects with a neutral foot alignment (p<.05). Based on these findings, the PG can be recommended as an effective instrument for evaluating the performance of the AbdH. It may also be beneficial for monitoring how well the SF exercise is performed, and for providing visual feedback to patients with pes planus during SF exercise in a clinical setting.

본 연구는 슬링을 이용한 능동 운동프로그램이 무릎 관절 전치환술 환자의 통증과 균형에 미치는 영향을 알아보고자 실시하였다. 대상자는 무릎 관절 전치환술을 받고 입원 중인 환자 20명이며, 수술 후에 CPM (Continuous passive motion) 만을 적용하는 집단 (CPM group; CG)과 CPM과 슬링을 이용한 능동 운동프로그램을 병행하는 집단 (CPM with active exercise program using sling group; CSG)으로 10명씩 무작위로 배치되었다. CG는 CPM을 주 5일, CSG는 CPM을 주 2일, 슬링을 이용한 능동 운동프로그램을 주 3일 실시하였고, 각 중재는 하루 40분씩 총 4주간 실시하였다. 통증은 VAS(Visual analog scale)을 이용하여 평가하였고, 균형은 BT4 (Balance training 4)를 이용하여 C90 area, Trace length, Sway average velocity를 눈을 뜬 상태와 감은 상태로 측정하였다. 그 결과, 두 집단 모두 통증에서 집단 내에서 유의하게 감소하였고, 집단 간의 변화량에서도 유의한 차이가 있었다. 균형에서 CG의 C90을 제외한 모든 변인이 중재 후 유의한 변화가 있었으며, 집단 간 변화량에서는 눈을 감은 상태의 C90과 Vel에서 유의한 차이가 있었다. 따라서 CPM과 슬링을 이용한 능동 운동프로그램을 함께 시행하는 것은 무릎 관절 전치환술 환자의 통증 감소와 균형 향상에 효과적인 중재라고 생각한다.

Purpose: This study examined the effects of the fumanet exercise program on the cognitive function and fall down-related physical fitness factor in elderly people. Method: The study period was May 2-June 24, 2016. The participants included 20 elderly persons (control group 10, experimental group 10) who registered at the day-care Center in G. City. Descriptive statistics were used for the analysis of the control and experimental groups' general characteristics. The chi-square and Mann-Whitney U tests were conducted to identify the two groups' general characteristics' and dependent variables' homogeneity. The Wilcoxon signed-rank test was used to compare the pre-and post-intervention cognitive function and fall down-related physical fitness factor, and a Mann-Whitney U test was used to analyze the rate of cognitive function and fall down-related physical fitness factor changes between the groups after the intervention. Result: The participants' fall down-related physical fitness factors (balance, gait, leg strength) increased and memory in the cognitive function sub-area improved in the participants who participated in the fumanet exercise program. The amount of change in gait was significantly different between the control and experimental groups. Conclusion: The fumanet exercise program included gait training using the learn, remember and repeat phased steps. Therefore, this study proposes using the fumanet exercise program to improve the elderly's cognitive function and physical fitness factor.

This study was conducted to examine the effect of children's dietary quality, dietary habits, food behavior and health-related lifestyles according to the mother's lifestyles of health and sustainability (LOHAS). The subjects were 580 children. Mother's LOHAS attitude index was 66.85 points and 100 points was a perfect score. The mother's high LOHAS attitude items that children perceived were "My mother often communicates with the family"(3.99 points) and "My mother thinks that the family's health is more important than her health"(3.93 points). In contrast, the LOHAS attitude items for "My mother does community service activity on weekends"(2.78 points), and "My mother participates in environmental protection service activity for the local community"(2.78 points) were very low. The high LOHAS behavior index of mothers was "resource saving", whereas "social welfare" scored low. When self-perceived health status and monthly income of children was high, the mother's LOHAS score was high. The LOHAS attitude index of mothers had a meaningful impact on the children's dietary quality, dietary habits, food behavior and health-related lifestyles. The most frequent food behavior variables were "high skipping rate", "frequency of snacks is 2~4 times per week", "speed of eating is rapid", and 'meals' amount is sufficient. The highest daily life habits item was "I try to maintain a pleasant and enjoyable life style"(3.42 points). The highest nutrient intake attitude score was "I tend to eat rice everyday."(3.41 points). They were highly recognized with "moderate physical activity", "high exercise preference", "positive posture exercise", "exercise <2 days per week", and "over 30 minutes exercise time per day" for the exercise performance status items. It was verified that the higher mother's LOHAS lifestyle score is, the higher children's food behavior, daily life habits, nutrient intake, exercise performance state score are.

[Purpose] The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the im-provement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function. [Methods] In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM). [Results] Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group. [Conclusion] These results suggest that the composition and timing of protein intake are more important than the total amount.

To assess the effect of pinitol supplementation and strength training for two weeks on the anaerobic capacity during and after exercise, and improvement of glucose metabolism during the recovery period of muscular fatigue with repeated acute bouts of cycling exercise, a total of 24 healthy young men were recruited and randomly and equally divided into three groups; pinitol supplementation group (PSG), placebo group (PLG), and control group (CON). Using a randomized double-blinded design, subjects in PSG were provided pinitol supplement, consumed orally 1.2 g/day, and participated in the resistance exercise program and cycling exercise for two weeks. Subjects in PLG underwent the same protocol as those in PSG but consumed the same amount of placebo. No supplementation and exercise program was given to CON. Before and after the intervention, all subjects were tested for their anaerobic capacities evaluated by Wingate test twice separated by 30 min. During the test, peak anaerobic power (PP), mean anaerobic power, total work, and fatigue index were evaluated During resting and recovery, blood samples were drawn and plasma pinitol, myo-inositol, chiro-inositol, insulin, free fatty acid, glucose, and lactate levels were analyzed After two weeks, PP and relative PP of the second biking were improved from the first biking in PSG only (p<0.05). No changes were found in all other variables of Wingate test in all groups. No statistical differences between groups and pre- and post-intervention were observed in concentrations of pinitol, myo-inositol, and chiro-inositol, but pinitol concentration was higher during recovery compared to the baseline in all groups and testings (p<0.05). Lactate level during recovery was higher than the resting level, but no other blood parameters were significantly changed. In conclusion, two weeks of pinitol supplementation in conjunction with short duration of anaerobic training in healthy young men did not induce any obvious benefits in terms of anaerobic capacity and energy metabolism Individual and/or population susceptibility may be one factor responsible for adopting pinitol supplementation.

Purpose : The purpose of this study was to investigate the effect of backward walking exercise on changes in the cervical angle and gait parameters in subjects with moderate forward head posture. Methods : Four subjects were selected for this study. In particular, subjects with an average of 43 subjects with moderate craniovertebral angles were selected as the criteria for subject selection. The exercise program consisted of a 5 minutes warm-up exercise, 20 minutes main exercise, and 5 minutes cool-down exercise. In the main exercise, the treadmill speed was 2.5 km/h for men, 2.0 km/h for women in the first week, from the 2nd week to the 4th week, it was increased by 0.5 km/h every week. Results : Craniovertebral angle increased by 2.06±2.46 ° before and after the backward walking exercise, and craniorotational angle decreased by -1.69±3.33 ° before and after exercise. As for the gait parameters, in the amount of change before and after the backward walking exercise, the left foot pressure was 4.58±5.70 % from front to back and the right foot pressure was 5.08±3.06 % from front to back. The left step length and right step length showed a change of -.33±4.43 cm and -2.08±7.26 cm, respectively. stride length showed a change of -2.59±11.18 cm. The left and right stance phase showed a change of -1.02±2.03 % and -1.23±1.54 %, respectively. The left and right swing phase showed changes of 1.02±2.03 % and 1.22±1.53 %, respectively. The left and right step times were -.01±.06 sec and -.02±.12 sec, respectively. The stride time showed a change of -.03±.18 sec. Conclusion : Changes in cervical angle and gait parameters were confirmed by performing backward walking exercise for subjects with moderate forward head posture for 4 weeks. Therefore, additional research should be conducted based on this case study.

Objectives: The purpose of this study is to investigate the effect of exercise load on sleep structure and stress hormone secretion during sleep. Methods: Five male physical education students were included in this study after giving their written, informed consents in the Research Institute for Sports Science at the University of Hanyang. All subjects have performed for at least 3 years in a regular aerobic exercises such as football, basketball, and running. The subjects were divided into three groups ; NOE(non-exercise), MDE(middle duration exercise), LDE(long duration excercise). MDE group maintained a total of 120 min exercise, and LDE group maintained a total of 300 min exercise by football, basketball or badminton. All subjects were acclimatized to the experimental sleep condition by spending one night under expermental conditions, including the placement of an intravenous catheter. During the subsequent night(24:00-08:00), somnopolygraphic sleep recordings were obtained, and blood for measuring growth hormone, cortisol, testosterone, and $\beta$-endorphin was collected every 120 min throughout the night. Blood samples were obtained from prominent forearm veins of subjects. Then, the samples were immediately placed in ice and centrifuged within 10 min at 3000 rpm at $4^{\circ}C$. Statistical analyses were performed using the SPSS/$PC^+$. Data were analyzed by one-way ANOVA with repeated measures. Results: No significant differences among groups were observed in sleep latency, total sleep time, stage 2 sleep, and slow wave sleep. However, daytime exercise produced significant changes in stage 1 sleep, REM sleep, stage 2 sleep latency, REM sleep latency and sleep efficiency. Stage 1 sleep, stage 2 sleep latency, and REM sleep latency significantly increased in LDE compared to those of NOE and MDE groups. But the amount of REM sleep significantly decreased in LDE. Sleep efficiency of MDE was higher than those of NOE and LDE. The blood concentrations of growth hormone, testosterone, and cortisol during night sleep were significantly lower in LDE than in NOE. $\beta$-endorphin concentrations in blood during night sleep were not different among groups. Conclusion: The daytime exercise load was significantly related to sleep structure and stress hormone secretion during night sleep. Long duration exercise showed a harmful effect on sleep structure and hormone secretion. However, middle duration exercise had a beneficial effect on sleep structure and hormone secretion during sleep.

Young adults are likely to start a new life style which may cause weight gain or obesity since leaving their parents for higher education or university. Whilst young people are slim in general, it is common to see them trying to manage their weight. Few studies have been carried out in Korea to support those changes in lifestyle that can result in weight gain in early adulthood. This study aims to identify prevalence of dieting as well as factors inducing weight gain among university students under unrestricted living conditions. A total of 99 university students were enrolled and asked to complete a questionnaire over a 3-day study period from June to September, 2008. T-test and $X^2$-test were applied to compare each behavior between weight gainers and maintainers. Logistic regression was also used for further analysis. Half of the participants used 'eat less' and 'exercise' as a way of dieting, and weight gainers tried to control their weight significantly more than weight maintainers. Most participants were engaged in very little exercise and were more likely to watch TV and use a computer. The time of lunch was proven as the only factor to predict weight change in the participants. As a result of this study, an intervention to promote exercise with friends or as a group is required to makeup for the lack of exercise among young adults. Further studies are also necessary to investigate how each meal time a day relates to the amount of food eaten. (Korean J Community Nutrition 14(4) : $374{\sim}382$, 2009)
