Whole body vibration training (WBVT) has been used as a supplement to conventional exercise training such as resistance exercise training to improve skeletal muscle strength, specifically, in rehabilitation field. Recently, this exercise modality has been utilized by cardiovascular studies to examine whether WBVT can be a useful exercise modality to improve cardiovascular health. These studies reported that WBVT has not only beneficial effects on muscular strength but also cardiovascular health in elderly and disease population. However, its mechanism un-derlying the beneficial effects of WBVT in cardiovascular health has not been well documented. Therefore, this review highlighted the im-pacts of WBVT on cardiovascular health, and its mechanisms in con-junction with the improved muscular strength and body composition in various populations.

Maternal infection is an important factor causing neonatal brain injury and later developmental disability. In the present study, we investigated the effects of treadmill exercise intensity on short-term memory, hippo-campal neurogenesis, and expression of brain-derived neurotrophic factor (BDNF), and tyrosine kinase receptor B (TrkB) in the rats born of lipopolysaccharide (LPS)-exposed maternal rats. The rats were divided into six groups: control group, mild-intensity exercise group, moder-ate-intensity exercise group, maternal LPS-exposed group, maternal LPS-exposed and mild-intensity exercise group, maternal LPS-exposed and moderate-intensity exercise group. The rats in the exercise groups were forced to run on a treadmill for 30 min 5 times a week for 4 weeks. The exercise load consisted of running at the speed of 8 m/min for the mild-intensity exercise groups and 14 m/min for moderate-intensity ex-ercise groups. The latency in the step-down avoidance task was deter-mined for the short-term memory. Immunohistochemistry for 5-bro-mo-2’-deoxyuridine was performed to determine hippocampal cell pro-liferation and neurogenesis. Western blot analysis was performed for the detection of BDNF and TrkB expression. In the present study, tread-mill exercise improved short-term memory deteriorated by maternal LPS exposure. Treadmill exercise increased cell proliferation and neu-rogenesis in the hippocampal dentate gyrus of the rats born of the LPS-exposed maternal rats. Treadmill exercise increased BDNF and TrkB expression in the hippocampus of the rats born of the LPS-ex-posed maternal rats. These effects of treadmill exercise were similarly appeared at both mild-intensity and moderate-intensity.

Depression is a major cause of disability and one of the most common public health problems. In the present study, antidepressive effect of treadmill exercise on chronic mild stress (CMS)-induced depression in rats was investigated. For this, sucrose intake test, immunohistochem-istry for 5-bromo-2’-deoxyuridine, terminal deoxynucleotidyl transfer-ase-mediated dUTP nick end-labeling staining, and Western blot analy-sis for brain-derived neurotrophic factor, cyclic adenosine monophos-phate response element binding protein, and endothelial nitric oxide synthase were conducted. Following adaptation to the animal vivarium and two baseline fluid intake tests, the animals were divided into four groups: the control group, the CMS-induced depression group, the CMS-induced depression and exercise group, and the CMS-induced depression and fluoxetine-treated group. The animals in the CMS groups were exposed to the CMS conditions for 8 weeks and those in the control group were exposed to the control conditions for 8 weeks. After 4 weeks of CMS, the rats in the CMS-induced depression and ex-ercise group were made to run on a motorized treadmill for 30 min once a day for 4 weeks. In the present results, treadmill exercise alleviated CMS-induced depressive symptoms. Treadmill exercise restored su-crose consumption, increased cell proliferation, and decreased apop-totic cell death. The present results suggest the possibility that exercise may improve symptoms of depression.

Antidepressants are drugs that relieve symptoms of depressive disor-ders. Fluoxetine, tianeptine, and milnacipran are different types of anti-depressants, and they have widely been used for relieving of depres-sion symptoms. In the present study, the effects of fluoxetine, tianeptine, and milnacipran on the glycine-induced ion current by nystatin-perfo-rated patch clamp and on the amplitude of field potential in the hippo-campal CA1 region by multichannel extracellular recording, MED64, system, were studied. In the present results, fluoxetine, tianeptine, and milnacipran reduced glycine-induced ion current in the hippocampal CA1 neurons in nystatin-perforated patch clamp method. These drugs enhanced the amplitude of the field potential in the hippocampal CA1 region in MED64 system. These results suggest that antidepressants may increase neuronal activity by enhancing field potential through in-hibition on glycine-induced ion current.

This research aims to develop a questionnaire of deviant behavior for the Korean elderly people which may make a big contribution to the ex-amination of deviance behavior of the elderly people and may play an important role in providing a methodological basis. In order to accom-plish the purpose of the this study, there were three different stages; (a) making preliminary question items, (b) refining the items of the scale through a plot study, and (c) finalizing question items by a main survey. In the first stage, 43 question items were developed using the open-ended questionnaire and structural inquiry of succession from 137 elderly people who are over 65 yr. In the second phase, based on data collected by the 200 elderly people pilot testing was performed through exploratory factor analysis and reliability test. The scale is a 27-item self-report questionnaire. In the main survey conducted by 184 el-derly people, 21 items, which consisted of four subfactors, were final-ized in order to measure deviance behaviors of the Korean elderly peo-ple: social deviance (n=8), economic deviance (n=5), psychological deviance (n=5), and physical deviance (n=3).

The purpose of this study is to verification of relationship model be-tween Korean new elderly class’s recovery resilience and productive aging. As of 2013, this study sampled preliminary elderly people in Gyeonggi-do and other provinces nationwide. Data from a total of ef-fective 484 subjects was analyzed. The collected data was processed using the IBM SPSS 20.0 and AMOS 20.0, and underwent descriptive statistical analysis, confirmatory factor analysis, and structure model verification. The path coefficient associated with model fitness was ex-amined. The standardization path coefficient between recovery resil-ience and productive aging is β=0.975 (t=14.790), revealing a statisti-cally significant positive effect. Thus, it was found that the proposed ba-sic model on the direct path of recovery resilience and productive aging was fit for the model.

Scuba diving itself is generally known as a safe sports. However, vari-ous injury accidents can happen, and the incidences vary depending on divers’ education grade levels about the risks. Therefore, the study set out to identify and analyze the causes and patterns of injuries de-pending on the divers’ safety education grade levels through a ques-tionnaire survey targeting ocean divers (n=12), sports divers (n=16), and dive leaders (n=15), all of whom belong to the British Sub-Aqua Club. After conducting a frequency analysis on the collected question-naires, the conclusions are made as follows. First, in terms of diving depth, the most frequent diving depth was 15–20 m among ocean div-ers, 20–25 m among sports divers, and 15–20 m in case of dive leaders. Second, with regard to the causes of injuries, the most frequently an-swered causes are ‘overtension’ and ‘low skill’ among ocean divers; ‘low skill’ among sports divers; ‘overaction’ among dive leaders. Third, in terms of injury patterns, the most frequently answered injury patterns are ‘ear’ injuries among ocean divers; ‘ankle’ injuries among sports div-ers; ‘ankle’ and ‘calf’ injuries among dive leaders. Fourth, with regard to who performed first-aid when an injury accident happened, the most frequent answers are ‘instructor’ among ocean divers; ‘instructor’ and ‘self’ among sports divers; ‘self’ among dive leaders. We might suggest that more efforts need to be made to improve divers’ low dependence on specialists for treatment and consultation so that we can prevent an injury from leading to the second injury accident.

The purpose of this qualitative study was to understand and examine how patients with rheumatoid arthritis (RA) experience climate care and its effects. A qualitative approach was chosen for the study. Two men and six women were interviewed according to a semistructured interview guide. The text was analyzed using a manifest content analy-sis. The analysis resulted in four categories and 10 subcategories. The interviewees experienced climate care positively. The training was per-ceived increasing gradually. The patients felt that they performed to a maximum capacity during training and were impressed by the staff’s enthusiasm and encouragement. The patients felt that they were in-volved in the goal setting and the choice of treatment, and the staff no-ticed individual needs. There was a feeling among the patients of being acknowledged by the staff. Information about the disease was per-ceived as individualized. The climate and beautiful surroundings were viewed as encouraging physical activity and a feeling of well-being. Patients made new friends, had fun together and also shared experi-ences about their disease. Furthermore, the patients described a sense of belonging to a group as well as a feeling of not being the only one that was sick among the healthy. Not having to do everyday tasks and having time to themselves were perceived positively. Several factors contributed to the positive experiences of climate care; climate, envi-ronment, physical activity, social context, staff involvement, and infor-mation about the disease were described as interacting together and resulting in a sense of well-being. A proposal for future research would be to examine if/how the various factors might interact and affect the RA patients’ illness and quality of life.

The main aim of this study was to evaluate the perceived level of diffi-culty and fear of movement among patients with chronic low back pain (CLBP) compared with asymptomatic subjects when they visualized motor control therapeutic exercises (MCTEs) commonly used in physio-therapy. Our secondary objective was to analyse the correlation be-tween fear of MCTEs and other psychological and disability variables. Thirty patients with CLBP comprised the treatment group, and 30 as-ymptomatic subjects comprised the control group. The procedure con-sisted of showing photographs and videos of seven MCTEs and having the participants rate their perceived difficulty and fear. Participants then answered a series of psychological self-report measures. Differences were found between groups in perceived difficulty of the MCTEs shown in videos (F=21.06, P<0.001) and photographs (F=15.86, P<0.001), as well as for perceived fear (F=9.71, P<0.001; F=8.61, P<0.001, respec-tively). Regression analysis indicated that in the CLBP group the predic-tor variable for perceived difficulty and fear was the lumbar disability (explaining 44% and 28% of the variance, respectively), however in the control group the predictor variables were catastrophizing and self-effi-cacy (38% and 34% of the variance, respectively). In conclusion, pa-tients with CLBP experience greater perceived level of difficulty and fear of movement when visualizing MCTEs than asymptomatic subjects. Psychological factors and disability were correlated with perceived dif-ficulty and fear when videos and photographs of exercises were shown.

This study compared nutritional intake, body composition, bone mineral density, and isokinetic strength by dance type in collegiate female dancers. The study subjects included Korean dancers (n=12), ballet dancers (n=13), contemporary dancers (n=8), and controls (n=12). Nutritional intake was estimated using the Computer Aided Nutritional Analysis Program. Body composition and bone mineral density were measured using dual-energy X-ray absorptiometry. Isokinetic knee joint strength was measured by Cybex 770-NORM. All statistical analyses were performed by SAS 9.2. Means and standard deviations were cal-culated using descriptive statistics. One-way analysis of variance was applied to evaluate nutritional intake, body composition, bone mineral density, and isokinetic strength differences. Duncan multiple range test was used for post hoc testing. A level of significance was set at P<0.05. The study results indicated no significant differences in nutritional in-take among dancer types. Despite no significant differences in body composition among dancer types, contemporary and ballet dancers had lower body fat percentages than controls (P<0.05). No significant differences were seen in bone mineral density and bone mineral con-tents among dancer types. No significant differences were found in isokinetic strength in right or left knee flexion and extension at 60°/sec (P<0.05). There were significant differences in body composition and isokinetic strength between dancer groups and the control group. Fur-ther studies of different professional dance type and more scientific methods of dance training are needed.

This study examined sources of variability in habitual physical activity of children, and the minimum number of days required for estimating chil-dren’s habitual physical activity levels using pedometers. A total of 31 children wore two pedometers during five weekdays and four weekend days. A two random facet completely crossed design was conducted with two-way analysis of variances across weekdays, weekends, and weekdays and weekend days combined. Moderate/high generalizabili-ty coefficients were estimated across all days. Primary sources of vari-ability were variance components of the person and person by day in-teraction. Minimum numbers of days required for estimating habitual physical activity levels using a pedometer were five during weekdays. However, estimating habitual physical activity levels during weekends, and weekdays and weekend days combined was impractical.

Depression is a general public health problem; there is an association between regular exercise or vigorous physical activity and depression. Physical activity has positive physical, mental, and emotional effects. The purpose of this study was to examine the relationship between de-pression symptom and physical performance in elderly women. A total of 173 elderly women aged 65 to 80 participated in this study. We evalu-ated elderly women using the 6-min walk, grip-strength, 30-sec arm curl, 30-sec chair stand, 8-foot up and go, back scratch, and chair sit and reach, and unipedal stance, measured the body mass index (BMI), and depression symptom assessed using Korean version of the Geriat-ric Depression Scale (GDS-K). The collected data were analyzed using descriptive statistics, correlation analysis, paired t-tests, and simple lin-ear regression using IBM SPSS Statistics ver. 21.0. There were signifi-cant correlations between GDS-K and the 6-min walk, 30-sec chair stand, 30-sec arm curl, chair sit and reach, 8-foot up and go, and grip strength tests (P<0.05), but not BMI, back strength, and unipedal stance. When divided into two groups (GDS-K score≥14 and GDS-K score<14), there was a difference between the two groups in the 6-min walk, 30-sec chair stand, 30-sec arm curl test, chair sit and reach, 8-foot up and go test, and grip strength test performances. Physical perfor-mance factors were strongly associated with depression symptom, suggesting that physical performance improvements may play an im-portant role in preventing depression.

The purpose of this study was to investigate whether pelvic stabilization affects multifidus (MF) and iliocostalis lumborum (IL) muscle activities during dynamic extension exercise. Nine males (age, 25.1±6.3 yr; height, 176.6±2.4 cm; body mass, 74.9±6.7 kg) performed an isometric lumbar extension strength test and dynamic exercise in an upright seat-ed position with or without pelvic stabilization. The electromyography and muscle strength of the MF and IL muscles were measured when the subjects performed the isometric lumbar extension strength test at the trunk angle 110˚, 146˚, and 182˚. In addition, the trunk extensor mus-cle activities were measured using 50% muscle strength of maximum isometric strength during a dynamic trunk extension exercise. The MF and IL muscle activities were significantly higher at 110°, 146°, and 182° with pelvic stabilization than that without pelvic stabilization during the isometric lumbar extension strength test (P<0.05) and the dynamic ex-ercise (P<0.05). These results suggest that the lumbar extension exer-cise with pelvic stabilization may be more effective for MF and IL mus-cle activity compared to that without pelvic stabilization.
