연구배경: 호흡곤란은 심폐질환 환자의 가장 흔한 증상이며 호흡 장애 결과로 인한 운동 능력저하는 일상 생활을 불가능하게 한다.(daily disability) 운동시 산소 소모량은 운동 능력 평가의 기능적 척도이며 심폐기능 정도를 반영하는 가장 좋은 지표로 얄려져왔다. 그러나 운동 부하 검사는 장비가 비싸고 복잡하며 증상이 심하거나 노령층의 환자에는 수행에 많은 제약점이 따른다. 반면 걷기검사는 일상 생할과 비슷한 운동량으로 실시하여 특별한 장비가 필요없고 재현성이 높은 좋은 방법으로 알려져 있다. 따라서 호흡 곤란을 호소하는 환자에서 걷기검사를 시행하여 동맥혈검사 및 폐기능 검사, Modified Borg Scale(MBS), 최대 산소 흡수율(maximal oxygen uptake; 이하 VO2max) 간의 상관 관계 및 6분과 12분 걷기검사간의 상관 관계를 알아보고자 본 연구를 시행하였다. 방법: 호흡곤란을 주소로 내원한 37 명의 환자를 대상으로 COPD, 심혈관질환, 기관지 천식, 운동시 호흡곤란을 호소하였으나 정상 소견을 보인 네 군으로 분류하여 각각의 환자에서 안정 상태에서 폐기능 검사와 동맥혈 가스 분석을 실시하였다. 안정 시 MBS를 이용하여 호흡곤란 지수를 기록하고, 걷기검사를 실시하였다. 증상 제한적 최대 운용 검사(Symptorn-limited maximal exercise)는 자전거 타기 검사로 시행하였다. 결과: (1) 전체 환자에서 VO2max 은 COPD 및 심혈 관질환에서 다른 두군에 비해 유의하게 낮았으며 (p<0.05), 걷기검사 역시 현저히 낮았다. (2) 전체 환자에서 12분 걷기 검사는 VO2max, PaCO2, FVC(% predicted), FEV 1 (% predicted)과 상관관계가 있었으며, COPD 환자군에서는 걷기검사와 VO2max간에만 상관 관계가 있었다. (3) COPD 환자군에서 VO2max와 FEV1, FVC간의 상관관계가 가장 컸고, VO2 max와 걷기검사간에 유의한 상관관계가 있었으나 걷기검사와 FEV1 FVC간에는 상관관계가 없었다. (4) 6분 걷기검사와 12분 걷기검사는 매우 유의한 상관관계가 있었다(r=0.92, p<0.01). 결론: 걷기검사는 심폐기능을 반영하는 운동능력 평가의 간단한 방법으로 VO2max의 간접적인 지표로 유용하였으나 최대 운동 능력과는 다른 개념인 'daily disability'를 평가할 수 있는 방법이다. 또한 6분 걷기검사는 12분 걷기검사보다 환자의 부담은 줄이면서 심폐질환자의 폐기능 및 운동 기능 평가에 비슷한 결과를 보였다.

Objective : The purpose of this study was to investigate the effects in the muscle function following 8-week dead-lift training with Whole-body Vibration(WBV) in rehabilitation for sports players. Method : Twenty young sports players. Each subjects were randomly assigned to a resistance training with Whole-body vibration group(TG, n=10), a resistance training without Whole-body vibration group(CG, N=10). The measurements which physical fitness test and joint torque test were performed before the randomization and after the 4-week and 8-week. The WBV group performed the dynamic Dead-lift exercise on a vibration platform during one minute. The CG group performed the equal training without vibration. The WBV and CON group repeated 5 set and trained two times weekly for 8-weeks. Paired t-test was used to test for differences between the groups at baseline and after 4-weeks and 8-Weeks. And independent t-test was used to test for differences between the groups at TG and CG. All analyses were executed using SPSS software 18.0. The level of significance was set at p<.050. Results : Following the 8-Weeks training sessions, an increase in the back-muscle strength was found to be greater for the TG compared with the CG group(p<.05). Muscle endurance was significantly decreased after training than before training only for the CG(p<.05). Isometric Hip/Lumber Extension/Flextion measurement was found to be significantly greater for the TG compared with the CG group(p<.05). The finding indicates that WBV effects as an efficient training stimulus to enhance muscle function by facilitating neural control trail. Following muscle activation in motor unit synchronization of the co-contraction of the muscles. Conclusion : The results imply that the WBV training may have enhanced muscle function in rehabilitation for sports players.

The purpose of this study was to investigate the needs for exercise of adult inpatients and ultimately to provide basic data for planning nursing intervention of patients who need exercise. The tool used for this study was a structured questionnaire which consisted of 42 items. The test items were classified into seven factors. The seven factors of the needs for exercise were need for achievement, need for activity, need for affiliation, need for autonomy, need for catharsis, need for homeostasis, and need for exhibition. Subjects of this study were 127 patients in two general hospitals in Seoul, and one general hospital in Chun Ann City. The needs of exercise were identified and the data were analyzed by gender, age, occupation, education level, monthly income, size of patient room, patient group who requires exercise and the other patient group who requires bed rest, using one-way ANOVA and Scheffe test as post-hoc. The findings of this study were as follows ; 1) Among the needs for exercise of adult patients, the highest level of the needs was the need for homeostasis. The next highest was the need for achievement, then need for activity, need for catharsis, need for autonomy, need for affiliation, and the lowest was the need for exhibition. 2) Maintaining physical fitness stood first in the need for homeostasis, relieving psychological and physical powerlessness in the need for activity, mood diversion in the need for catharsis, happiness of the family in the need for affiliation, maintaining the balanced body figure in the need for exhibition, practicing planned life in the need for achievement, and improving the ability to overcome the crisis in the need for autonomy. 3) Male patients exhibited the higher level of the needs than female patients in all factors except the need for exhibition and homeostasis. 4) There was no statistical difference in the needs between age, occupation, monthly income, and the size of patient room. 5) The need for achievement was high as the level of education goes higher. 6) The patients who performed regular exercise before admission had higher needs for activity, achievement, and autonomy, compared with the patients who did not perform the regular exercise before admission. 7) There was no statistical difference in the needs between patient group who requires exercise and the other patient group who requires bed rest. The need for homeostasis was the highest in both groups. The results from this study suggest that the need for exercise of adult inpatients should be assessed before planning exercise intervention.

Hypertension is among the most common and important risk factors for stroke, heart attack, and heart failure which is considered to be the leading cause of death in Korea. The prevalence rate of hypertension in Korea is 27.9%, according to the 2006 Korea National Health and Nutrition Survey. Since non-pharmacologic nutrition education is recommended as the first step in the management of hypertension, evaluation of nutrition program is needed to form strategies for improving patients' dietary adherence. This study was designed to evaluate the overall effectiveness of a hypertension nutrition education program (HNEP) for reducing the salt intake, at a public health center located in Gyunggi-province. The HNEP was offered for 16 weeks from May to September in 2007. Nutrition education activities included cooking classes, food preparation demonstrations, physical fitness programs, salty taste preference test sessions, games, case-study presentations, planning and evaluation of menus, etc. Forty patients participated fully in the program which had 47 female enrollees. Data about nutrient intake (24-hour recall), nutrition knowledge, food behavior were collected before (baseline) and after the program. Changes after program completion indicated the following: 1) diastolic blood pressure was decreased (p < 0.05), 2) sodium (salt) intake was also decreased (p < 0.01), especially baseline high salt intake group, 3) nutrition knowledge was improved (p<0.001), 4) dietary behaviors for maintaining a low salt diet was improved (p < 0.001), 5) participants preferred cooking class from nutrition education methods. As a conclusion, it appears that a nutrition education program for hypertensive female elderly for reducing the salt intake might effectively decrease blood pressure and salt intake. It also improves nutrition knowledge, dietary behavior, and finally adherence to a recommendable low-sodium diet.

The purpose of this study was to elucidate incidence of $VO_2$ plateau by comparing data derived from different time averaging intervals during incremental cycling exercise to $VO_2max$. Seventeen subjects (age: $23.5{\pm}3.3$ years and $VO_2max$: $3.65{\pm}0.73$ L/min, respectively) completed $VO_2max$ tests on cycle ergometer which breath by breath gas ex-change data were obtained. These data were time-averaged into 11-breath, 15, 30 and 60 s sampling intervals. The incidence of plateau were 100, 35, 24 and 6% for the 11 breath, 15 s, 30 s and 60 s averaging, respectively. No correlation was between ${\Delta}$ $VO-2$ at $VO_2max$ and $VO_2max$ (r=0.008). 53% (maximal HR within 10 b/min) and 100% $(RER{\geq}1.15)$ of subjects met the criteria for attainment of $VO_2max$. This data indicate that shorter sampling intervals (11 breath) is the most suitable for de-tection of the $VO_2$ plateau and RER can be used for the criteria for attainment of $VO_2max$ but not maximal HR. Also, the incidence of a plateau is not related to training status or physical fitness of subjects.

In this paper, we designed and implemented IoT sensors based badminton motion analysis and training system that can be readily used by badminton players with PC. Unlike the traditional badminton training system which uses signals of the flags by coach, the proposed electronic training system used IoT sensors to automatically detect and analysis the motions for badminton players. The proposed badminton motion analysis and training system has the advantage with low power, because it communicates with the program through BLE communication. The badminton motion analysis system automatically measures the training time according to the player's movement, so it is possible to collect objective result data with less errors than the conventional flag signal based method by coach. In this paper, training data of 5 athletes were collected and it provides the feedback function through the visualization of each section of the training results by the players which can enable the effective training. For the weakness section of each player, the coach and the player can selectively and repeatedly perform the training function with the proposed training system. Based on this, it is possible to perform the repeated training on weakness sections and they can improve the response speed for these sections. Continuous research is expected to be able to compare more various players' agility and physical fitness.

The purpose of this study was to determine the effects of aerobic rhythmical exercise program on $VO_2$ max, leg strength, grip strength, flexibility, exercise self-efficacy and quality of life in elderly. This quai-experimental study was designed as a non-equivalent control group pretest-posttest study. 36 subjects, aged between 65 and 73 years who have normal cognition. sensory function and cerebellum function participated in this study. 19 experimental group subjects participated aerobic rhythmical exercise program. Aerobic rhythmical exercise program was developed on the basis of calisthenics, stretching, aerobic exercise, Korean traditional dance and music by the author. The program consisted of approximately 1 hours of exercise, 3 times a week for 9 weeks. During 1 hours workout, there were 15 minutes of warm-up dancing, 35 minutes of conditioning dance and 10 minutes of cool-down dancing. The intensity for the conditioning phase was between $40\%\;and\;60\%$ of age adiusted maximum heart rates. The $VO_2$ max, grip strength, leg strength, flexibility, exercise self-efficacy and quality of life were measured prior to and following the experimental treatment. Data were analyzed with $x^2-test$, t-test, mean, standard deviation. percentage of change and ANCOVA test using SAS program. Results were obtained as follows. 1. The $VO_2$ max of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=7.76, p=0.008). 2. The grip strength of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=4.61, p=0.039). 3. The leg strength of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=9.29, p=0.000). 4. The was no significantly difference of flexibility between experimental and control group 5. The self-efficacy of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=43.40, p=0.000). 6. The quality of life of the experimental group were significantly lower than those of the control group following the aerobic rhythmical exercise program(F=8.91. p=0.005). The results suggest that aerobic rhythmical exercise program can improve $VO_2$ max, grip strength. leg strength. exercise self-efficacy and quality of life elderly.
