A randomized control trial was conducted to investigate the synergistic effects of Gotu kola supplementation and multicomponent exercise on cognitive function, inflammation, and oxidative stress in older adults with mild cognitive impairment (MCI). Sixty participants aged 74.6±7.3 years with Mini-Mental State Examination (MMSE) scores of 20.7±2.6 were randomly assigned to one of three groups: a multicomponent exercise training group (EXE, n=20), a multicomponent exercise training with Gotu kola supplementation group (EXE+GK, n=20), or a placebo-controlled group (CON, n=20). Each participant received one capsule of placebo or 500 mg twice a day of Gotu kola extract. The multicomponent exercise program comprised of supervised resistance, aerobic, balance and dual-task training: three 80-min sessions/week for 12 weeks. The primary outcomes, such as cognitive function, inflammatory markers, and oxidative stress, were measured before and after the 12-week intervention. Following the interventions, the EXE and EXE+GK had significantly higher MMSE (P<0.01), Digit Span Forward test (DSF) (P<0.01), Digit Span Backward test (P<0.01) scores, and lower Trail Making Test parts A (P<0.01) and B (P<0.01) and lower 8-iso-prostaglandin F2α (P<0.01) and tumor necrosis factor alpha (TNF-α) (P<0.01) than the CON. The change in DSF and TNF-α in the EXE+GK had a negative correlation (r=-0.504, P<0.05). In conclusion, multicomponent exercise training with or without the supplement Gotu kola improves cognitive function, inflammation, and oxidative stress in older adults with MCI. Although supplementing with Gotu kola had no additional effects on cognitive function, it may improve the effects of multicomponent exercise on executive function by decreasing TNF-α levels.

This study aimed to analyze nursing diagnoses determined by the nursing students for patients in rehabilitation unit. Data were collected from 190 case reports submitted by the nursing students who practiced in the rehabilitation unit, and analyzed on the basis of North American Nursing Diagnosis Association (NANDA) International, Inc. nursing diagnoses. Thirty different diagnoses were documented in rehabilitation unit. The most frequent nursing diagnosis was impaired physical mobility (n=68, 14.6%). The 30 diagnoses were grouped into 10 domains and 20 classes of the NANDA International, Inc. human response patterns. The average quality of nursing statements corresponded to a score of 8.63, indicating relatively good quality. The results of this study will help to improve the quality of nursing process education and provide guidelines to improve the quality of nursing care for the rehabilitation nursing situation in Korea.

The purpose of this study is to identify the factors affecting the job stress of commercial sports center workers on organizational commitment and turnover intention. The causal relationship between their demographic characteristics and job stress was investigated for 261 out of 300 workers working at commercial sports centers in Seoul, Incheon, and Gyeonggi province. There was a difference by work type, and it was found that there was a difference between regular and contract workers. Role-related and interpersonal relationships had a negative influence relationship in terms of tenure commitment, normative commitment, and affective commitment. Job characteristics, role-related, interpersonal relationship, and compensation system had an influence on turnover intention. In other words, it was found that role-related and interpersonal relationships had a positive effect on turnover intention, and job characteristics and compensation system had a negative effect on turnover intention. It was found that job stress affects both organizational commitment and turnover intention. The results of this study indicate that job stress, organizational commitment, and turnover intention should be dealt with mainly in order to reduce turnover intention of commercial sports center workers. In other words, clearer guidelines on the role of commercial sports center workers and various welfare programs for improving human relationships should be provided. Therefore, commercial sports centers should continuously research and develop ways to maximize job satisfaction from the perspective of workers in order to reduce job stress and induce positive organizational commitment.

This study aimed to investigate the adequacy of the visual-motor inte-gration (VMI) scale for Korean elderly (VMIS-KE) compared to tradition-al measures, mini-mental state examination of Korean version (MMSE-KC) and Beery VMI for cognitive decline in diabetic older adults. For this explanatory research, data were collected from September 1 to Sep-tember 15, 2013, from 34 diabetic older adults and 31 nondiabetic older adults in Daegu and Gyeongsan of Korea. Mean differences between the two groups were analyzed with SPSS 18.0. The diabetic older adults showed significantly lower scores in the VMIS-KE (t=4.128, P<0.001) and MMSE-KC (t=2.231, P=0.029) compared with the nondiabetic older adults. In all subcategories of VMI-KE, figure cognition (t=5.342, P<0.001), memory (t=3.011, P=0.004) and spatial cognition (t=2.639, P=0.011), there were significant differences whereas no significant difference in the VMI-6th revision (t=0.994, P=0.325). VMIS-KE could be a sensitive indicator to assess cognitive change in older adults with diabetes and health care providers should periodically evaluate vulnerable groups such as them with it.

It is necessary to understand movement characteristics of elite female soccer players during a match to develop effective training program. The purpose of this study is to analyze the physical demands of Korean female professional soccer players during a competitive season. Twenty-four female professional players (age: 27.8±3.9 years; height: 165.7± 5.1 cm) from a team, belonging to the women's professional soccer league in South Korea participated in the study. The players participated in 11 home matches and 10 away matches from April 26 to November 9 of the 2011 season. Body weight and body mass index decreased during the first half-season compared to the preseason (P<0.05), and the decreased values were maintained until the second half-season. Total distance covered by the players was more than 9.5 km per match. No difference was found in the total distance, movement distance by exercise intensities, number of sprints and accelerations, and maximum speed between the first half- and second half-seasons. Midfielders covered the most distance during a match compared to other positions (P<0.05). Wing forward covered the most distance of high-intensity exercise. Maximum speed during the match was higher among wing forward and forward than in other positions (P<0.05). There were no significant differences between home and away matches in all variables (P>0.05). In conclusion, in order to improve the performance of female soccer players and prevent injuries, a training program should be constructed that considers the characteristics of each player and playing position rather than uniform training in a team.

The purpose of this study was to determine whether the timing of tread-mill exercise application can control expression levels of neuropathic pain- and regeneration-related proteins in the ipsilateral lumbar 4 (L4) to 6 (L6) dorsal root ganglion cells (DRG) after sciatic nerve injury (SNI). The experimental rats were randomly divided into five groups: the normal control, SNI+sedentary (IS), exercise+SNI (EI), SNI+exercise (IE), exercise+SNI+exercise (EIE) groups. The rats in exercise groups per-formed treadmill exercise at a speed of 8 m/min for 30 min once a day during 14 days before and/or after SNI. For investigating the expression of specific neuropathic pain and regeneration-related proteins in DRG, we prepared L4 to L6 DRG in the ipsilateral side. In the quantitative analysis, growth associated protein 43 (GAP-43) and brain-derived neurotrophic factor levels were further increased in the ipsilateral DRG at all treadmill exercise groups than those in IS group. In the histological findings, GAP-43 was qualitatively increased IE and EIE groups than IS group at DRG. Wnt3a and β-catenin were dramatically downregulated in EIE and IE groups than IS groups. In addition, nuclear factor kappa-light-chain-enhancer of activated B cells and tumor necrosis factor-α were significantly decreased in IE and EIE groups than IS group in the ipsilateral DRG. Our findings suggested novel information that regular low-intensity exercise before and/or after SNI might be a therapeutic and preventive approaches for relieving neuropathic pain and improving axonal elongation after peripheral nerve injury.

Scoliosis is defined as a deviation from the normal vertical line of the spine and consists of a lateral curvature in which the spine rotates within the curvature. Adolescent idiopathic scoliosis (AIS) is the most common form of scoliosis and the cause is unknown. In this study, it was investigated whether conservative treatment for adolescent idiopathic scoliosis (CONTRAIS) reduced the patient's Cobb angle, and the effect of CONTRAIS according to the severity of idiopathic scoliosis and the efficacy of CONTRAIS by spinal region were also verified. Idiopathic scoliosis patients with a Cobb angle of 10° or more were recruited and classified into mild, moderate, and severe groups according to the Cobb angle (°). Cobb angle was measured radiographically before and after 10 weeks of treatment. A combination of CONTRAIS, including physical therapy, exercise therapy, manual therapy, and home exercise was prescribed for all patients. The patients visited the hospital 3 times a week for 10 weeks for treatment, and exercised at home for 20 min every day. In this study, the effect of reducing Cobb angle of CONTRAIS did not differ according to the spinal region. Also, the Cobb angle reduction effect of CONTRAIS was more effective in severe group. This study may suggest that early detection and treatment through CONTRAIS enables successful correction of AIS.

In this study, the effect of chronic alcohol intake for 4 weeks on the muscular atrophy factors of rat skeletal muscle was studied using 6-week-old growing Sprague-Dawley rats. Experimental animals were classified into a control group and an alcohol intake group. The alcohol intake group consumed alcohol orally at a concentration of 3-g/kg body weight every day for 4 weeks. The control group consumed tap water in the same way. After 4 weeks alcohol ingestion, glucose, total cholesterol, triglyceride, and high-density lipoprotein cholesterol in serum levels were measured. Western blot was performed to detect the expressions of muscle RING-finger protein-1 (MuRF1), protein kinase B (Akt), phosphorylated Akt (p-Akt), forkhead box O (FoxO), phosphorylated FoxO (p-FoxO), p38, and phosphorylated p38 (p-p38). Results of this experiment showed that chronic alcohol intake enhanced triglyceride concentration. Chronic alcohol intake increased MuRF1 expression to promote muscle proteolysis and decreased p-Akt/Akt ratio and p-FoxO/FoxO ratio to inhibit skeletal muscle growth. Therefore, alcohol consumption has been shown to cause muscle atrophy.

This study was conducted to analyze the relationship between locomotive syndrome and sarcopenia in the old people using a functional evaluation tool. In this study, 237 Korean old people selected from the Miraeseum Seongnam Senior Complex and the Misa Riverside Welfare Center were diagnosed with the two diseases and the Berg balance scale was performed to confirm the deterioration of dynamic balance sensory. Through the diagnostic evaluation of the two diseases, the locomotive group (n=180) and the sarcopenia group (n=34) were classified and statistically analyzed. As a result of the study, a significant difference in dynamic balance sensory between the two diseases was confirmed, and a significant negative correlation was confirmed with 25-question geriatric locomotive function scale and grip strength among the diagnostic evaluation items of the two diseases. These results suggest that gradual deterioration of locomotive syndrome and sarcopenia occurs in the deterioration of physical performance in the old people, suggesting that the evaluation of locomotive syndrome can be used as a screening test for sarcopenia.
