[Purpose] The purpose of this study were to assess physiological and biochemical characteristics in elderly women with osteosarcopenic obesity (OSO), and to analyze relationships among irisin, adipokines and bone metabolism markers. [Methods] 126 elderly women were selected and among them 10 women were classified into OSO group (76.9±5.2 yrs) and 14 women were classified as a NOSO group (72.9±5.6 yrs). Physique, body composition and bone mineral density were measured. Senior fitness tests were 30-s chair stand, 30-s arm curl, chair sit-and-reach, back scratch, 8-foot up-and-go, grip strength, and 2-min step test. Isokinetic muscle strength was measured by isokinetic dynamometer (Cybex 770, USA). Nutrition intake and physical activity were administered. Biochemical parameters including irisin, FNDC-5, leptin, adiponectin, CTx, 25(OH)D, osteocalcin, and PTH were measured. All data were analyzed by SAS 9.4. Independent t-test was applied to compare between OSO and NOSO groups. Multiple regression analysis was used. The level of significance was set at .05. [Results] The results of the study showed that there were significantly high for waist circumference, hip circumference, WHR, and BMI in OSO group compared to those of NOSO group. Higher results were also obtained for fat tissue and percent body fat but significantly low for lumbar bone mineral density. OSO group showed significant lower results for grip strength and 2-min step test compared to NOSO group. Peak torque, and relative peak torque at 60° were significantly lower for left and right knee flexion in OSO group. Protein intake was significantly low in OSO group, but no difference was obtained in level of physical activity between two groups. Irisin was significantly related to adiponectin, FNDC-5 and osteocalcin in explaining 35.2%, 81.5% and 92.1% of the variance, respectively. [Conclusions] This study shows that elderly women with OSO have higher results for physique and body composition parameters except body height. However, lower values were obtained for functional fitness, and isokinetic muscle strength. OSO may have more risks for metabolic syndrome, bone fractures, fall, lack of daily physical activity and limit of locomotion due to the imbalance of quadriceps and biceps femoris in non dominant leg. This study suggests that criteria and mechanism of OSO should be clarified by follow-up study. [목적] 본 연구는 골다공증-근감소성 비만(Osteosarcopenic obesity; OSO) 고령여성의 생리적 특성, 기능체력, 등속성 근기능 특성을 분석하고, OSO집단의 아이리신과 아디포카인, 골대사지표의 관련성을 조사하는 것이다. [방법] 본 연구는 60세 이상 고령여성 126명을 대상으로 골다공증, 근감소증, 비만의 기준으로 3가지 표현형을 모두 가진 고령여성 10명(OSO집단: 76.9±5.2 yrs)과 3가지 표현형을 모두 가지지 않는 고령여성 14명(NOSO집단: 72.9±5.6 yrs)으로 구분하여 체격, 신체구성과 골밀도(Hologic, QDR- 4500W, USA), 기능체력(Senior fitness test), 등속성 근력(Cybex 770, USA), 영양소 섭취량(CAN-Pro, version 4.0, Korea), 신체활동량(IPAQ)을 측정·분석하였다. 생화학적 변인으로는 아이리신(Irisin), FNDC5, 렙틴(Leptin), 아디포넥틴(Adiponectin)과 골대사지표(Osteocalcin, CTx, 25(OH)D, PTH)를 비교·분석하였다. 집단 간 차이를 규명하기 위하여 독립 t-검증을 실시하였으며 OSO집단의 Irisin 수준에 영향을 미치는 생화학적 변인을 분석하기 위하여 stepwise 다중회귀분석을 실시하였다. [결과] 신장은 OSO집단이 유의하게 낮게 나타난 반면, 허리둘레, 엉덩이둘레, 허리-엉덩이 비율(WHR), 체질량지수(BMI)는 NOSO집단보다 유의하게 높게 나타났다. 지방조직과 체지방률에서는 OSO집단이 NOSO집단보다 유의하게 높았으며 요추골무기질량과 골밀도에서는 NOSO집단보다 유의하게 낮았다. 기능체력은 악력과 2-min step test에서 OSO집단이 NOSO집단보다 유의하게 낮았다. 등속성 근력은 60°/sec에서 최대근력은 좌·우측 굴곡근에서 OSO집단이 유의하게 낮았으며, 체중 당 최대근력과 평균파워는 우측 굴곡근, 좌측 신전근, 좌측 굴곡근에서 유의하게 낮게 나타났다. 180°/sec에서 최대근력, 체중 당 최대근력, 총 일량 모두 좌측 굴곡근에서 OSO집단이 유의하게 낮게 나타났다. 영양소 섭취량에서는 단백질섭취량이 OSO집단이 NOSO집단보다 유의하게 낮았으며 신체활동량은 OSO집단에서 낮은 경향을 보였다. 렙틴의 경우 OSO집단이 NOSO집단보다 유의하게 높게 나타났으며 OSO집단의 Irisin 수준에 영향을 미치는 생화학적 변인으로는 Adiponectin, FNDC5, Osteocalcin이 유의하게 영향을 미치는 것으로 나타났다. [결론] 결론적으로 OSO집단이 대사증후군, 노화, 골절 등 위험에 더 노출되어 있는 것으로 판단되며, non dominant leg의 대퇴사두근과 대퇴이두근의 불균형으로 인한 낙상위험 증가와 일상생활과 관련된 기능체력, 이동성에 제한이 있는 것으로 사료된다. 향후 OSO의 특징을 더 명확히 규명하기 위한 cohort 연구와 운동프로그램 적용을 통한 종단연구가 진행되어야 할 것으로 판단된다.

정성우(Jung, Sung-Woo),서명원(Seo, Myong-Won),김성우(Kim, Sung-Woo),김덕윤(Kim, Deog-Yoon),송종국(Song, Jong-Kook) 한국체육과학회 2017 한국체육과학회지 Vol.26 No.5

We examined the effects of 16 weeks combined exercise training on irisin, adipokines, bone metabolism markers, functional fitness and isokinetic muscle function in elderly women with osteosarcopenic obesity in elderly women. 16 participants who were 65 years of age or older were recruited and were randomly assigned into training group (n=8; TG) and control group (n=8; CG) Body composition and bone mineral density (BMD) were measured by DXA (Hologic, QDR-4500, USA). Senior fitness tests were 30-s chair stand, 30-s arm curl, chair sit-and-reach, back scratch, 8-foot up-and-go, grip strength, and 2-min step test. Isokinetic muscle strength was measured by isokinetic dynamometer (Cybex 770, USA). Biochemical parameters including irisin, leptin, adiponectin, C/Tx, 25(OH)D, osteocalcin, and PTH were measured. All data were analyzed by SAS 9.4. Two-way repeated measures ANOVA was applied. Following of combined exercise training, lumbar BMD was increased significantly (p<.05) in the training group, while fat mass and lean body mass were not changed in both TG and CG. Significant improvements were obtained for 30-s chair stand (p<.001), 8-foot up-and-go (p<.01) and 2-min step test (p<.05) in the training group. Relative peak torque in left extensor (p<.001), flexor (p<.01) and right flexor (p<.05) at 60 degree was increased significantly between pre-and post-tests. Left extensor relative total work done (p<.01), right flexor relative total work done (p<.05) and left flexor relative total work done (p<.05) at 180 degree were also increased significantly in TG. Combined exercise training improved significantly the level of irisin (p<.05) and 25(OH)D (p<.05) during intervention period. Our major findings indicate that 16 weeks combined exercise training increased level of irisin, and 25(OH)D and improved lumber BMD, functional fitness and isokinetic muscle function. We can conclude that combined exercise training is effective in preventing osteoporosis and age-related decline in muscle function.

김나혜 ( Kim Na-hye ),박정희 ( Park Jeong-hui ),서명원 ( Seo Myong-won ),전정우 ( Jeon Jeong-woo ),이정민 ( Lee Jung-min ) 한국체육학회 2021 한국체육학회지 Vol.60 No.2

이 연구는 2019년 청소년건강행태온라인조사 자료를 활용하여 BMI가 정상범위에 있으면서도 체중조절을 시도한 청소년을 대상으로 체중조절 방법과 정신건강(스트레스, 우울 및 자살)의 관계를 분석하고자 하였다. 이를 위하여 2019년 제15차 청소년건강행태온라인조사의 원시자료를 이용하였으며, 연구 대상자는 BMI가 정상범위이면서 체중조절을 시도한 8,075명을 체중조절 방식에 따라 네 집단으로 구분하였다(그룹 1: 규칙적인 운동, 그룹 2: 약물 및 단식과 같은 부적절한 방법, 그룹 3: 규칙적인 운동+부적절한 방법, 그룹 4: 체중조절을 시도하지 않은 집단). 모든 자료는 SPSS 25 ver.를 이용하여 분석했으며, 각 변수에 대한 빈도분석과 체중조절을 시도하지 않은 집단을 기준으로 대상자의 일반적 특정을 보정한 후 다항 로지스틱 회귀분석을 실시하였다. 그 결과 첫째, 여자 청소년은 남자 청소년 보다 운동, 약물 및 단식 등과 같은 다양한 체중조절 방법을 시도할 가능성이 높게 나타났으며, 연령이 높을수록 체중조절을 위해 운동을 시도할 가능성은 낮아졌다. 둘째, 그룹 1 (규칙적인 운동)이 그룹 2(약물 및 단식)보다 스트레스를 적게 받을 가능성이 높았으며, 그룹 3(규칙적인 운동+부적절한 방법)의 스트레스 정도는 더욱 심해질 것으로 나타났다. 셋째, 세 집단 (그룹 1, 2, 3) 모두 우울감을 느낄 가능성이 높게 나타났다. 넷째, 그룹 3(규칙적인 운동+부적절한 방법)의 경우 자살행동(자살생각, 자살시도)을 시도할 가능성이 다른 집단에 비해 높게 나타났다. 본 연구는 BMI가 정상범위에 있는 청소년들의 체중조절 시도 방법과 정신건강(스트레스, 우울 및 자살)간의 연관성을 확인하였으며, 청소년들의 부적절한 체중조절 시도가 정신건강과 밀접한 관련이 있는 것으로 나타났다. 특히, 자살과 같은 심각한 정신적 문제가 발생하기 이전에 건강 생활에 대한 교육과 더불어 올바른 신체관과 건강한 심신의 함양을 위해 학교와 가정이 연계된 실효성 있는 교육 방안이 제시되어야 한다. The purpose of this study was to investigate the association of personal characteristics and weight control methods on stress, depression, and suicidal behavior in adolescents who tried to control their weight. This study was used from the 15th Online Adolescent Health Behavior Survey in 2019. Eight thousand seventy-five adolescents who attempted weight control were included in this study while their BMI was in the normal category. Descriptive statistics and multinomial logistic regression analysis for each variable were performed using SPSS 25 ver. As a result of the analysis, female adolescents were more likely to control weight with exercise (OR=2.061) or exercise plus inappropriate methods (OR=3.682) than male adolescents. The who tried exercise plus inappropriate methods group was associated with a risk of stress (OR:4.265; Severe stress). Also, exercise (OR=1.202), exercise plus inappropriate methods group (OR=2.070), inappropriate (OR=2.205), shown a high risk of depression. Exercise plus inappropriate methods also shown a relativly high risk for suicide behavior (Suicidal Ideation; OR=1.215, Suicide attempt: OR=1.461). This present study demonstrated that inappropriate weight control practices among adolescents greatly influenced their mental health. Therefore, it is necessary to support preventive education programs regarding appropriate weight-control strategies for adolescents.

The purpose of the study was to compare skeletal maturity, bone mineral density, physical fitness, aerobic and anaerobic capacity in children who participated in different sports. Fifty boys (swimming: N=14; soccer: N=24; taekwondo: N=12), aged 10-12 years old, volunteered to participate in the study. Physique including height, weight, and body circumference were measured. Body composition and bone mineral density were assessed by DXA (Hologic, Co., QDR-4500, USA). Skeletal maturation was evaluated by TW3 method. Physical fitness tests (flamingo balance, sit and reach, grip strength, standing long jump, and side step) were administerd. For aerobic capacity parameters, the Bruce protocol was conducted on the treadmill with Quark b2 (Cosmed, Co., Italy). The Wingate anaerobic power test was performed. All data were expressed as mean and standard deviation. One-way ANOVA was applied to evaluate the difference among sport events. There was a significant difference in skeletal age among groups (F=4.01, p<.05). The swimming group has the most advanced chest circumference compared to the soccer or taekwondo group. There was a significant difference in femoral bone mineral density among groups (F=10.62, p<.001). Sit-ups (F=19.17, p<.0001), and the side-step test (F=12.44, p<.0001) showed significant differences among groups. The soccer group (68.3±7.05 ml/kg/min) had a significantly higher level of peak VO_2max than the swimming group (61.7±8.06 mL/kg/min) (F=3.52, p<.05). Significant differences in relative anaerobic peak power (F=3.87, p<.05), and mean power (F=4.89, p<.05) were observed among groups. In conclusion, there were differences in skeletal maturity, bone mineral density, aerobic and anaerobic capacity, and physical fitness in adolescent boys who participated in different sports. Longitudinal study is necessary to investigate clear relationships between physical activity levels, sports events, life style, and energy intake in children.

The aim of the study was to determine the effects of participation in short and long track speed skating on body composition, bone mineral density, physical fitness, and aerobic capacity in male adolescents. Forty male adolescents aged 14-17years participated in this study. Subjects were divided into three groups(Control[CON]: n=13, Intermediate Skating Group[ISG]: n=13, Advance Skating Group[ASG]: n=14) according to their skating career(CON=0yr, ISG=3.0±1.08yr, ASG=8.0±1.41yr). Body composition and bone mineral density were assessed by DXA(QDR-4500, Hologic, USA). Physical fitness test included sit and reach, standing long jump, grip strength, and sit-ups. VO2max was measured by the Bruce Protocol on the treadmill with Quark b2(Cosmed, Italy). One-way ANOVA was applied to evaluate the difference among the groups. Significant differences were observed for lean body mass (F=4.327, p<.05), fat mass (F=7.882, p<.001), percent body fat (F=13.755, p<.001), femur bone mineral density (F=5.202, p<.01), and lumbar bone mineral density (F=3.226, p<.05) between groups. There were significant differences on sit and reach (F=11.419, p<.001), grip strength (F=3.882, p<.05), sit-ups (F=30.411, p<.001), and standing long jump (F=3.545, p<.05) among groups. Both speed skating groups (ISG= 72.3±8.64ml/kg/min; ASG=75.9±7.12 ml/kg/min) had a significantly higher peak VO₂max than the control group (56.5±6.97mL/kg/min)(F=25.494, p<.001). This study showed that participation in short and long track speed skating improves body composition, bone mineral density, physical fitness, and aerobic capacity during adolescence. Therefore, long term participation in short and long track speed skating is essential for healthy growth and health.

The aims of the study were to determine physiological characteristics of elite and non-elite speed skating athletes and to analyze factors impacting on speed skating performance related to the skating distance events. Subjects were 30 elite and non-elite athletes and they were divided into two groups based on athletic achievement medal including elite(short distance 7, middle and long distance 8) and non-elite athletes(short distance 8, middle and long 7). Body composition and bone mineral density were measured by DXA(Hologic, QDR-4500W, USA). Physical fitness test included sit-reach, grip strength, sit-ups, standing long jump, and 50m shuttle run. Aerobic and anaerobic capacity was measured. Isokinetic muscle strength was a ssessed u sing Cybex 770 NORM. The results o f the study showed that elite athletes had higher lean body mass(p<.05) and femur bone mineral density(p<.05) than nonathletes. Elite athletes showed better performance in sit-ups(p<.05) and 50m shuttle run(p<.05) than non-athletes but no difference in aerobic and anaerobic capacity between two groups. Factors such as anaerobic power, standing long jump, and sit-reach were significantly related to 500m skating performance. Mean anaerobic power and lean body mass were related to 1000m, and VO2max and left and right knee maximal muscular extension were related to 1500m. In conclusion, elite athletes had different body composition parameters and showed greater performance in physical fitness compared to non-elite athletes. Several factors relating to the distance of speed skating performance should be taken into account for athlete’s training and injury prevention.

The aim of the study was to compare body composition, physical fitness and isokinetic strength between short-track and speed skaters. The subjects who participated in this study were 33 short-track skaters and 21 speed skaters who were enrolled in Korea Ice Skate Association in 2014. Anthropometric measurements included body height and body weight. Body composition was measured by DXA. Physical fitness tests included sit and reach, grip strength, sit-ups, standing long jump and 50m shuttle run. Aerobic and anaerobic capacity were also measured. Isokinetic muscular strength was measured by Cybex 770. The results of the study indicated that anaerobic fatigue(p<.05), muscular endurance(p<.05) in short-track skaters was significantly greater than in speed skaters. 50m shuttle run(p<.05) in speed skaters was significantly greater than short-track skaters. However, no differences could be obtained in body composition, sit and reach, grip strength, sit-ups, standing long jump and aerobic capacity between the two groups. This may have implications for training and performance both in short-track and speed skating.

스포츠 조직 여성 구성원의 직무 스트레스와 사회적 적응의 관계

서명원 한국학교체육학회 2000 한국학교 체육학회지 Vol.10 No.1

최근 들어 여가 및 스포츠에 대한 일반인의 욕구가 증대됨에 따라 이를 충족시키기 위한 수단으로서 스포츠 센터가 급증하고 있으며, 보다 쾌적한 환경 속에서 고품질의 '스포츠 서비스'를 제공할 수 있는 상업 스포츠 센터의 수가 늘어나고 있는 추세에 있다. 이처럼 스포츠 센터의 규모가 커지고 그 구성원의 수가 많아짐에 따라 스포츠 조직의 효율적인 관리에 대한 비중이 점차 증대하고 있다. 본 연구에서는 특히 상업 스포츠 센터에서 근무하고 있는 구성원 중에서 많은 비중을 차지하고 있는 여성 구성원의 직무 스트레스와 사회적 적응의 관계에 대하여 고찰하였다. 본 연구에서는 서울에 위치한 상업 스포츠 센터에서 근무하고 있는 여직원 356명을 대상으로 하여 연구를 수행하였다. 결과분석을 위하여 사용한 본 연구에서 사용한 통계분석 방법은 일원변량분석과 중다희귀분석 이었다. 이러한 연구 목적과 방법을 통해 나타난 결론은 다음과 같다. 첫째, 스포츠 조직 여성 구성원의 인구통계학적 특성에 따라 직무 스트레스와 사회적 적응에는 차이가 있다. 즉 직무 스트레스는 연령이 높을수록, 학력이 높을수록, 근무경력이 오래될수록, 그리고 연봉이 많을수록 높다. 사회적 적응은 20세-25세 미만 연령의 근무자가, 고졸이하의 학력자가, 1년-3년 미만의 경력자가 높다. 둘째, 스포츠 센터 여성 구성원의 직무 스트레스와 사회적 지원은 사회적 적응에 유의한 영향을 미친다. The purpose of this study was o find the relationships between job stress and social adjustment the female employees who work in the commercial sport organizations. For this purpose, a total of 356 female employees were sampled and analysed who welted at the commercial sport centers which were located in Seoul City. The questionnaire method was used to investigate the relationships between job stress, self-esteem, and social adjustment. Collected data were analysed by SPSS programs. And the statistical methods far the analysis of the study were one-way variance analysis(ANOVA) and multiple regression analysis. The results of this study were summarized as follows: First there was statistically significant differences in the job stress and social adjustment of the female employees in accordance with the demographic characteristics. Second, the job stress and self-esteem were the strong factors that affected to the social adjustment of the female employees.
