Purpose: A dance exercise program was performed to investigate the effects of exercise on exercise intention and exercise-related affect as these are important determinants of exercise behavior. Method: The subjects were overweight (23$\leq$BMI<25) or obese (BMI$\geq$25) postmenopausal women (n=14), who participated in an exercise program from May, 2003 through November, 2003 at one public health center located in Kyong-gi Province. Data was analyzed with an SAS PC program. Result: Exercise intention was significantly increased after the exercise program (t=-2.24, P=0.04). Exercise-related affect was also increased, but there was no statistically significant change (t=1.81, P=0.09). Conclusion: This study suggests that exercise participation can increase the level of future exercise behavior by increasing exercise intention and exercise-related affect.

Purpose: This study was performed to examine predictors of allied health science students' exercise behavior using Pender's Health Promotion Model. Method: The subjects were 203 university students majoring in nursing, emergency medical service, and exercise prescription. The hypothetical model was based on the HPM(Pender, 1996). Exogenous variables of the model were exercise habit and role belief. Endogenous variables were exercise-related affect, exercise self-efficacy, exercise barrier, exercise intention, and exercise behavior. The data were analyzed by SAS PC program and LISREL 8.12 program. Result: The degree of exercise behavior was low(mean 1.86, range 1~4). The overall fit of the model to the data was acceptable. Exercise habit, exercise self-efficacy and exercise-related affect were significant predictors of exercise intention and exercise behavior. Conclusion: This study shows the necessity of the program to increase the level of exercise participation of university students majoring in allied health science. The model constructed in this study is applicable to explain exercise behavior of university students majoring in allied health science, and suggests that we should focus on exercise habit, exercise self-efficacy and exercise-related affect to increase the level of exercise behavior of this group.

Purpose: This study was done to identify practical exercise performance and to define the factors related to exercise performance in middle-aged women. Methods: The researchers collected data from 206 middle-aged women, ages 40 to 59. The measurements used were a scale for degree of exercise performance, and self-efficacy scale, affect, perceived barriers and benefits related exercise, body-shape perception, and the youngest child's education stage. The data were analyzed with SPSS/WIN 17.0 and SAS program using t-test, ANOVA, and stepwise multiple regression. Results: Exercise performance showed significant differences according to body-shape perception (F=5.45, p<.01), the youngest child's education stage (F=4.44, p<.05). Exercise performance had a significant strong positive relation with self-efficacy (r=.616), a moderate relation with self-rated health (r=.428) and with affect related exercise (r=.519), a mild relation with perceived benefits (r=.339) and with social support (r=.239), and a negative mild relation with perceived barriers (r=-.330) with 99% significance. Self-efficacy, affect, perceived barriers, and the youngest child's education stage explained 46.4% of a variance in exercise performance in middle-aged women. The factor most influencing was self-efficacy related exercise at 37.9% of the variance. Conclusion: We can conclude that self-efficacy, affect, perceived barriers, and the youngest child's education stage should be considered as important factors for developing program of middle-aged women.

본 연구는 운동중독이 신체적, 정서적 삶의 질적 가치에 영향을 줄 수 있다는 전제하에 운동참여자의 사회인구학적특성에 따른 운동중독과 정서의 성향을 분석하고 운동중독과 정서는 어떠한 관련성이 있는지를 규명하여 운동참여자의 운동중독을 예방함과 동시에 합리적인 대처방안을 제시하고자 고찰하였다. 그 결과, 운동 참여자들은 테니스를 통하여 본인의 건강 유지 증진에 대한 심리적, 정서적 안녕감이 크게 작용하고 신체적인 기술성취의 중요성으로 인하여 운동중독현상과 더불어 긍정적, 부정적인 정서에도 유의한 영향을 미친다는 결과가 나타났다. 이러한 사실을 상기하여 각 개인에게 긍정적 참여행동을 주지시키는 것은 물론 지도자들은 테니스 운동 참여자들이 보다 긍정적인 운동수행이 되도록 운동 참여행동을 제시하고 이러한 행동을 지속적으로 수행해 나갈 수 있도록 하는 것이 건강을 위한 여가의 한 형태로서 테니스 운동참여가 이루어질 수 있는 올바른 방향이라 사료된다.

스텝운동(bench-step aerobics: BSA)이 과체중 및 비만 우리나라 성인 여성을 위한 효과성, 안전성 및 실행 가능성을 갖춘 운동 프로그램이라는 것이 다수 연구자들에 의해 시사되어 왔다. 그러나 그 효과성은 일부 생리적 효과에 한하여 검증되었을 뿐 심리적 효과에 대해서는 거의 연구되지 않았다. 따라서 본 연구는 스텝운동 프로그램이 우리나라 과체중 및 비만(체질량지수 ${\geq}\;2\;kg/m^2$) 성인 여성에게 미치는 심리적 효과를 알아보기 위해 수행되었다. 이러한 목적을 달성하기 위해 보건소 방문자와 지역신문 및 보건소 홈페이지 홍보를 통해 모집된 여성 중 편의 추출한 운동군 15명과 대조군 13명의 분노(anger), 운동관련 자기 효능감(exercise self-efficacy), 운동관련 정서(exericse-related affect), 그리고 신체상(body image)을 운동 프로그램 전후에 측정하여 비교하였다. 자료 수집은 12주 스텝운동 프로그램(2006년 8월${\sim}$11월) 전과 후에 보건소에서 이루어졌다. 운동군에게 적용된 스텝운동 프로그램은 중강도[개인의 예비 심박 수(Heart Rate Reserve : HRR)의 $40/50{\sim}50/60%$]로 $45{\sim}60$분 동안 주 3회 이루어졌으며, 상기 운동 강도 및 운동 시간은 대상자의 적응도에 따라 12주에 걸쳐 점진적으로 증가되었다. 12주간의 스텝운동 후 운동군의 신체상이 유의하게 개선되었으며, 이는 대조군에서의 변화와도 유의한 차이를 보였다. 분노, 운동관련 자기 효능감, 그리고 운동관련 정서 또한 개선되는 경향이었으나 통계적으로 유의한 변화는 보이지 않았다. 이로써 우리나라 과체중 및 비만 성인 여성 대상 스텝운동의 심리적 효과가 부분적으로 지지되고 있으나, 현재까지 이루어진 관련 연구가 거의 없고 본 연구 또한 연구 설계상의 제한점을 갖고 있으므로 연구결과의 일반화를 위한 추후 연구가 요구된다. 특히 Floor effect 및 Ceiling effect 등에 의한 효과를 배제하기 위해 분노 수준이 상대적으로 더욱 높거나 운동관련 정서 수준이 상대적으로 낮은 과체중 및 비만여성을 대상으로 반복 연구를 수행할 필요가 있다.

The purpose of present study is to examine the relative efficacy of active exercise programs for work-related chronic low back pain and to figure out how much they affect mechanical stability of lumbar. Subjects are 43 employees with work-related chronic low hack pain, and they were randomly divided into two groups with general physiotherapy groups and thoracic exercise groups for increasing thoracic mobility. Active exercise programs were done 3 times a week, for 6 months, and the subjects were tested for Pain intensity(VAS), the Oswestry Disability Index, Maximal stretching with both hands in the overhead direction and the lumbar region angle of inclination. All subjects were reassessed with same measurement with Pre-study and 6 months after study After applying active exercise programs, pain intensity didn't show any significant difference between two groups. The Oswestry Disability Index showed significant difference between two groups and thoracic exercise groups decreased significantly compare to general physiotherapy group(p<0.05). Maximal stretching with both hands in the overhead direction showed significant difference between two groups and thoracic exercise group increased significantly more than general physiotherapy groups(p<0.05). The lumbar region angle of inclination showed significant difference between two groups and thoracic exercise group decreased significantly more than general physiotherapy groups (p<0.05). According to the results above, exercise for increasing thoracic mobility has an effect on lumbar stability. For the work-related chronic lower hack pain workers, it is far more effective for lumbar stabilization than general physiotherapy.

Purpose: The purpose of this study was to verify the effectiveness of the model based on the TPB, behavior-related theories, and exercise-related empirical studies in predicting exercise intention and behavior. Methods: The subjects who participated in this study were 152 middle-aged women. The data were analyzed by use of SAS PC program and LISREL 8.12a program. Results: 1) The overall fit of the hypothetical model to the data was acceptable ($\chi^2$ 24.01(p=0.0043), $\chi^2/df$ 2.67, RMSEA 0.11, standardized RMR 0.04, GFI 0.97, AGFI 0.84, NFI 0.95, NNFI 0.85). 2) Affect, subjective norm, perceived behavioral control and habit were significant determinants of the exercise intention. Attitude and facilitating conditions were not significant determinants. These six variables explained 43% of the total variance of the exercise intention. 3) Perceived behavioral control and habit were significant determinants of the exercise behavior. Intention and facilitating conditions were not significant determinants. These four variables explained 95% of the total variance of the exercise behavior. Conclusion: This study shows the model's applicabiltiy in explaining exercise behavior of middle-aged women, and suggests that we should focus on perceived behavioral control and habit rather than intention to improve exercise behavior of middle-aged women.

Purpose : Bridge exercise has been commonly used in clinical rehabilitation settings to improve trunk control, and hip adductor muscles were a related muscle that may affect trunk muscle activation. The aim of this study was to investigate whether the co-contraction of hip adductor muscles may affect trunk muscle activation during bridge exercises. Methods : Thirty-eight healthy young subjects (19 men and 19 women) performed bridge exercises (with and without hip adduction movement). Surface electromyography (EMG) data were collected from the dominant-side internal oblique (IO), rectus abdominis (RA), multifidus (MF) and erect spine (ES) during bridge exercises to compare trunk muscles activation patterns. Result : The EMG activities of IO and RA appeared to be significantly higher during bridge exercise with hip adductor co-contraction than during bridge exercise alone (p<.01), but there were no significant differences in those of MF and ES. Furthermore, there were significant differences in the IO:RA EMG ratio during bridge exercise with hip adductor co-contraction (p<.05). Conclusion : These findings suggest that integration of hip adduction during bridge exercise may be beneficial in increasing deep muscles' activity for trunk stabilization.
