Objective: Patients with chronic obstructive pulmonary disease (COPD) may experience reduced physical activity and quality of life (QoL) due to decreased pulmonary function. The purpose of this study was to investigate the level of pulmonary function, physical activity, and QoL of COPD patients. Design: Cross-sectional observational study. Methods: This study examined the published data of the Korea National Health and Nutrition Examination Survey in 2015-2019. Among 39,759 subjects who participated for 5 years, data from 151 patients diagnosed with COPD were analyzed separately. For the pulmonary function, the results of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV6, forced expiratory flow 25-75%, and peak expiratory flow were observed. Physical activity was identified as frequency and duration. For the QoL, EQ-5D-3L evaluation results were examined, and the frequency and index of the Korean version were investigated. Results: In pulmonary function, all variables were found to be lower than age and weighted matched normal values. COPD patients showed to perform very low levels of high/medium physical activity and sitting time was confirmed to be more than 8 hours a day. In QoL, it was found that the highest reporting rate of some problems was the "pain and discomfort" and "mobility". Conclusions: It was found that COPD patients showed that the prevalence of circulatory disease was relatively high, lowered pulmonary function, and QoL. These can be improved through regular physical activity, and it is thought that this can be achieved through optimization of pulmonary rehabilitation.

본 연구는 만 65세 이상의 노인 49명을 대상으로 가속도계와 신체활동일기를 함께 사용하여 신체활동량과 좌식행동패턴을 성별에 따라 비교하고 WHO 신체활동지침의 실천율을 평가하였다. 1. CPM과 METs는 성별에 따른 유의한 차이가 없었으나 PAEE는 남자가 여자보다 유의하게 높았다. 활동 강도별 1일 평균 소요시간을 살펴보면, 본 연구대상자들은 좌식행동에 소요되는 시간 (남녀 각각 60.6%, 57.6%)이 가장 많았으며 좌식행동 및 중 고강도 활동의 소요시간에서는 남녀간의 유의한 차이를 보이지 않았으나 저강도 활동의 소요시간은 여자가 $364.2{\pm}74.5$분으로 남자 ($313.7{\pm}70.8$분)보다 유의하게 많았다. 2. 남녀 모두 수면시간을 제외한 좌식행동 (2 ~ 5단계) 중 2단계의 '휴식, 담화 및 TV보기' 활동으로 가장 많은 시간 (남자 26.9%, 여자 22.0%)을 보내고 있었으며, 남자가 $388.0{\pm}134.3$분으로 여자 ($316.1{\pm}65.2$분)보다 유의하게 많았다. 저강도 활동에 포함되는 활동 중에서는 7단계의 '미용 및 옷 갈아입기' 활동과 9단계의 '음식 준비 및 정리하기' 활동의 소요시간에서 여자가 남자보다 유의하게 많았다. 중 고강도 활동에서는 15단계의 '체조, 탁구 및 자전거타기' 활동의 소요시간에서 남자가 여자보다 유의하게 많게 나타났다. 3. 좌식행동패턴을 성별에 따라 비교한 결과, 좌식행동을 30분과 40분 이상 지속한 횟수에서 남자가 각각 $3.10{\pm}1.34$회, $1.78{\pm}1.09$회로 여자 ($2.34{\pm}1.22$회, $1.32{\pm}1.07$회)보다 유의하게 많았으나 시간당 좌식행동의 지속을 끊어주는 횟수는 남자 ($5.74{\pm}0.89$회)가 여자 ($6.44{\pm}0.71$회) 보다 유의하게 적었다. 좌식행동을 30분 이상 지속한 횟수 및 시간 당 좌식행동을 끊어주는 횟수는 2단계의 '휴식, 담화 및 TV보기' 활동의 소요시간과 유의한 상관관계를 보였으며 주로 저강도 활동을 통해서 좌식행동의 지속이 끊어지는 것으로 나타났다. 4. 일주일 동안 중 고강도 활동을 각각 2분과 5분 이상 지속한 시간에서는 남자가 $319.8{\pm}255.2$분과 $247.3{\pm}228.2$분으로 여자 ($193.3{\pm}130.6$분, $137.2{\pm}101.9$분)보다 유의하게 많은 것으로 나타났다. 또한 본 연구대상자의 경우 중 고강도 활동의 짧은 지속시간 (10분 미만)으로 인하여 WHO 신체활동지침의 실천율이 22.4% (남자 30.8%, 여자 13.0%)으로 매우 낮았다. 본 연구 결과를 통하여 노인의 경우 장시간 지속되는 좌식행동 패턴을 줄이기 위하여 노력해야함을 알 수 있었다. 이를 위하여 무엇보다도 앉아서 TV를 시청하는 시간을 줄이는 것이 중요함이 지적되었다. 앞으로 노인의 만성질환 예방을 위하여, 노인의 신체활동량 및 좌식행동 패턴과 건강 관련 지표와의 관련성 분석 평가 연구가 필요하다. 특별히 본 연구에서 노인만을 위한 별도의 신체활동지침 마련의 필요성이 제시된 바, 노인에게 적합한 신체활동의 적정 강도 및 적정 유지 시간 등이 반영된 새로운 지침이 개발되어야 할 것이다.

The relationship between bone mineral density and the environmental factors were investigated from the view point of preventing osteoporosis in Korean pubescent girls. The effects of calcium, nutrient intake, physical activity on total bone mineral density, lumbar spine and femoral bone mineral density and total bone mineral content were evaluated 33 healthy pubescent girls aged 14∼16y. A convenient method was used to assess nutritional and energy intake and calcium index was used together. Calcium intake in childhood was estimated by asking whether subjects usually drank milk as children. Eating habits data and history of menstruation were obtained by questionnaire and interview. Average energy expenditure was calculated. Bone mineral density and content were measured by dual energy x-ray absorptiometry using a Lunar DPX＋Scanner (Lunar, Madison, WI). The lumbar spine(L2∼L4) and three sites in the proximal femur (femoral neck, trochanteric region, and Ward's triangle)were measured. Height and weight were measured, and the body mass index(BMI) was derived from the formula : BMI=kg/㎡ Statistical analysis was performed by simple correlation using the SAS package. The mean calcium intake (736mg) was below the RDA of 800mg/d. Twelve percent of the total subjects did not drink milk at all because they did not like the taste. Skipping meals, low calcium intake and low energy intake were significantly correlated with the low BMD. Also the data indicate that girls who reported drinking milk with every meal during childhood had significantly higher bone densities than girls who reported drinking milk less frequently. The results suggest that milk consumption in childhood appears to be needed not only for growth and development, but possibly also to assure an optimal peak of bone mass and thus greater latitude for the maintenance or skeletal integrity in the face of bone losses. There was a highly significant correlation between the total BMD and overall level of physical activity. Body weight was a better predictor of total BMD than was and other factor. Simple mechanical loading may explain why body weight, but total BMC was positively relatd to height. Conclusively, increasing calcium intake and physical activity in the pubescent girls could influence BMD.

Background: The International Classification of Functioning, Disability and Health (ICF) model, created by the World Health Organization, provides a theoretical framework that can be applied in the diagnosis and treatment of various disorders. Objects: Our research purposed to ascertain the relationship between structure/function, activity, and participation domain variables of the ICF and pain, pain-associated disability, activities of daily living (ADL), and quality of life in patients with chronic low back pain (LBP). Methods: Two-hundred patients with chronic LBP (mean age: 35.5 ± 8.8 years, females, n = 40) were recruited from hospital and community settings. We evaluated the body structure/function domain variable using the Numeric Pain Rating Scale (NPRS) and Roland-Morris disability (RMD) questionnaire. To evaluate the activity domain variable, we used the Oswestry Disability Index (ODI) and Quebec Back Pain Disability Scale (QBDS). For clinical outcome measures, we used Short-form 12 (SF-12). Pearson's correlation coefficient was used to ascertain the relationships among the variables (p < 0.05). All the participants with LBP received 30 minutes of conventional physical therapy 3 days/week for 4 weeks. Results: There were significant correlations between the body structure/function domain (NPRS and RMD questionnaire), activity domain (ODI and QBDS), and participation domain variables (SF-12), rending from pre-intervention (r = -0.723 to 0.783) and postintervention (r = -0.742 to 0.757, p < 0.05). Conclusion: The identification of a significant difference between these domain variables point to important relationships between pain, disability, performance of ADL, and quality in participants with LBP.

Purpose: This study compared the different sling and resistance exercises on pelvic rotation during active straight leg raises (ASLR) and on pain in patients with chronic low back pain (CLBP). Methods: Twenty subjects were divided randomly into a sling group (SG) and a resistance exercise group (REG). Internal oblique (IO), external oblique (EO), rectus abdominis (RA), and rectus femoris (RF) muscle activity; pelvic rotation angle during ASLR; and visual analogue scale, pressure pain threshold were measured. Sling and resistance exercises were then performed for 30 minutes and the measurements taken again. Results: Both groups showed significantly lower RF muscle activity and significantly higher EO and IO muscle activity (p<0.05). The RA muscle activity decreased significantly in the SG, but increased significantly in the REG (p<0.05). The pelvic rotation angle was significantly lower in the SG (p<0.05). The pain press threshold increased significantly in both groups (p<0.05). The visual analogue scale decreased significantly in the SG (p<0.05). Conclusion: Both exercises appear to be beneficial for modifying the muscle activity and pain control in the intervention of CLBP. On the other hand, the sling was more effective in increasing the pressure threshold than resistance exercise, and the pelvic rotation angle was reduced. Therefore, both exercises can help patients with CLBP change their muscle activity and control pain. CLBP patients should use a sling for short periods of time to learn to reduce the pain and control pelvic rotation.

Purpose : The purpose of this study is to determine the effects of high heeled shoes on the static balance and EMG activity of lower extremity muscles. Methods Twenty subjects were composed of control group(wearing low-heeled shoes) and experimental group(wearing high-heeled shoes). Two groups participated in bearfoot standing and measured static balance and EMG activity of lower extremity muscles. Balance Performance Monitor(BPM) was used to measure the static balance and FlexComp $Infiniti^{TM}$ was used to measure the EMG activity of lower extremity muscles. Results In static balance, sway area and path of experimental group was significantly larger than control group(p<0.05). And sway velocity of experimental group was significantly faster than control group(p<0.05). They means static balance of experimental group was significantly lower than control group(p<0.05). In EMG activity, L5 paraspinalis and biceps femoris of experimental group was significantly more increased than that of control group(p<0.05). Conclusion : The long-time experience in wearing high heeled shoes may have caused change in static balance and EMG activity of lower extremity muscles.

Background: Previous studies investigating the association of physical activity with risk of lung cancer reported conflicting results. In order to update and improve available evidence on any link, a meta-analysis was performed. Method: We searched the PubMed database for prospective cohort studies investigating the relation of physical activity with risk of lung cancer. The pooled relative risk (RR) with its 95% confidence intervals (95%CI) was used to assess the association. Results: We included 14 prospective studies with a total of 1,644,305 participants, with 14,074 incident lung cancer cases documented during follow-up. Meta-analysis of all 14 studies suggested both high and medium levels of physical activity to be associated with decreased risk of lung cancer compared to the reference group with low level of physical activity (for high level, RR = 0.77, 95%CI 0.73-0.81, P < 0.001; for medium level, RR = 0.87, 95%CI 0.83-0.90, P < 0.001). Subgroup analyses by gender found obvious associations in both men and women. No publication bias was observed. Conclusion: Our findings suggest that high and medium levels of physical activity have a beneficial effect on lung cancer by reducing the overall risk of tumour development among both men and women.

Background: A typical plank exercise (PE) strengthens the core muscles, stabilizes the spinal column, and provides stability around the pelvis and trunk when the trunk is aligned. However, because PE require that the hip joint be kept straight, they can activate the hamstring (HAM). Excessive HAM activation can induce tightness, which may cause low back pain. Therefore, it is necessary to explore PE methods that can minimize HAM activity while maximizing core muscle activity. Design: Cross-sectional study. Methods: This study included 30 healthy adults as subjects. We measured the activity of the HAM and the erector spinae (ES), rectus abdominis (RA), and external oblique (EO) muscles using surface electromyography during three PEs (typical PE, PE with balance pad, and PE with sling). Results: The RA, EO, and ES showed the highest muscular activity during PE with balance pad and the lowest during PE with sling; however, the differences were not significant. The HAM showed lower activity during PE with sling than during the other two PEs; however, these differences were also not significant. Conclusion: Although HAM activation was not significantly difference among PE positions, we should recognize altering activation of core and hamstring muscle according to PE postures.
