Tai Chi is a low-impact and moderate intensity exercise that has shown positive effects in patients with musculoskeletal disorders. Recently have been developed clinical studies on the benefits of Tai Chi tech-niques combined with hydrotherapy. Both types of treatment include physical training of balance, mobility, strength, coordination and senso-ry input that could complement each other. This report aims to present the current evidence about the benefits of the combination of water based Tai Chi in musculoskeletal diseases in order to establish whether the combined intervention is better than Tai Chi or hydrotherapy alone.

This study aimed at presenting what factors are to predict the social isolation of the elderly as an element to prevent the problem of why var-ious matters related to old people are inevitably taking place by careful-ly examining the meaning of social isolation and the conditions of social isolation that the South Korean senior citizens go through after working on previous studies. This section discusses the results obtained through document analysis. First, the aspects of the elderly’s social isolation arising from the changes of the South Korean society are changes of family relationship, the social structure, the economic structure and the culture. Second, the social isolation and social activity of the elderly are problems (suicide, criminals, dementia, depression and medical costs) of the elderly, change trend of the elderly issues related to social isola-tion and prediction factors that personal and regional. Lastly, as a role and challenges of the field of rehabilitation exercise aimed at resolving social isolation should be vitalized such as the development and provi-sion of various relationship-building programs.

Huntington’s disease is a chronic neurodegenerative disorder inherited in an autosomal dominant fashion, and characterized as involuntary movement. Quinolinic acid has been used to produce an animal model of Huntington’s disease. In the present study, the effect of treadmill ex-ercise on spatial-learning ability and motor coordination focusing on the apoptosis in the hippocampus was investigated using quinolinic ac-id-induced Huntington’s disease rats. Huntington’s disease was induced by unilateral intrastriatal injection of quinolinic acid (2 μL of 100 nmol) using stereotaxic instrument. The rats in the treadmill exercise groups were subjected to run on a treadmill for 30 min once a day during 14 days. Spatial learning ability and motor coordination were determined by radial 8-arm maze test and rota-rod test. Immunohistochemistry for caspase-3 and western blot for Bax and Bcl-2 were also conducted for the detection of apoptosis. In the present results, spatial learning ability and motor coordination were deteriorated by intrastriatal injection of quinolinic acid. In contrast, treadmill exercise exerted ameliorating ef-fect on quinolinic acid-induced deterioration of spatial learning ability and motor coordination. Bcl-2 expression in the hippocampus was de-creased and expressions of casepase-3 and Bax in the hippocampus were increased in the quinolinic acid-induced Huntington’s disease rats. Treadmill exercise increased Bcl-2 expression and decreased ex-pressions of casepase-3 and Bax in the Huntington’s disease rats. The present results showed that treadmill exercise might ameliorate quino-linic acid-induced loss of spatial learning ability and motor coordination by suppressing apoptosis in the hippocampus.

We induced middle cerebral artery occlusion (MCAO) in rats using sili-cone-coated vascular embolus. We transplanted mouse embryonic stem (mES) cells after MCAO. Rats were tested behaviorally using mo-tor and sensory function with neurological assessment. Functional ef-fectiveness of the transplanted mES cells gradually improved the func-tion of sensory and motor neurons. This study demonstrated that the transplanted cells have synaptic connection in the recipient brain. We suggest that stem cell transplantation can have a positive effect on be-havioral recovery and reduction of infarct size in focal ischemic rats. Cell transplantation may induce certain functional recovery of the brain tissue by endogenous cell mediated effect. Our study suggests that in-tracerebrally injected mES cells survived and migrated into the infarct area from inoculation site and neuroglially differentiated in the ischemic brain area of adult rats. Therefore, mES cells may be a useful tool for the treatment in neurological diseases. In conclusion, cell transplanta-tion therapy represents a novel approach that may enhance the effica-cy and effectiveness of stem cell transplantation after ischemic stroke.

Menopause may increase risk of hypertension and abnormal lipid pro-file. The aim of the study was to examine the effects of morning and af-ternoon aerobic exercises on hypertension and lipids in overweight hy-pertensive postmenopausal women. Forty five women aged from 49 to 60 years were randomly assigned into three groups. Group (A) 15 pa-tients received medicine, (B) 15 patients performed morning aerobic exercises and received medicine, and group (C) 15 patients performed afternoon aerobic exercises and received medicine. Blood pressure measurement and lipid profile tests were performed before and after the study. The results showed that there was a statistical significant dif-ference among all groups in systolic and diastolic blood pressure, fa-voring group C. Also there was a statistical significant difference among all groups in lipid levels, favoring group C. Therefore, it can be conclud-ed that morning aerobic exercises were more effective in reducing the blood pressure and lipids than afternoon exercises in overweight hy-pertensive postmenopausal women.

The fear of falling is a common psychological consequence of falling, especially for elderly individuals. Fear of falling can lead to activity re-striction and medical problems. The primary purpose of this study was to examine the correlation between fall efficacy and physical fitness factors in elderly women. We assessed physical fitness factors and in-vestigated the Korean version of the Fall Efficacy Scale-International (KFES-I) in 173 participants. We investigated the correlation between physical fitness factors and fall efficacy. When the subjects were divid-ed into four groups according to physical fitness level, subjects with high 6-m walk, 30-s chair stand test, 30-s arm curl test, chair sit and reach test, 8-foot up and go test scores and high grip strength had low fall efficacy. Physical fitness factors were strongly associated with de-creased fall fear, suggesting that physical fitness improvements play an important role in preventing or reducing the fear of falling.

Therapeutic importance of physical activity during and after cancer treatment has been supported. To examine the patterns of physical ac-tivity according to the stages of breast and colorectal cancer survivor-ship in Korean, Korean National Health and Nutrition Examination Sur-vey data from 2008 to 2011 were used. International Physical Activity Questionnaire (IPAQ) was utilized to estimate weekly time spent in vig-orous- and moderate-intensity physical activity, and walking, and to calculate MET-minute/week. Depending on the survivorship, the sub-jects were categorized into “never diagnosed with cancer” (group 1), “0-4 yr since cancer diagnosis” (group 2), and “5 or more years since cancer diagnosis” (group 3), separately for colorectal and breast can-cer. The associations between physical activity and the cancer survi-vorship were studied. Following results were obtained: (1) Breast can-cer (n=10,167, mean age=48.55±16.27): The mean physical activity lev-els expressed in MET-minutes/week were 2,064.83, 1748.82, and 1998.36 in groups 1, 2, and 3, respectively. Even though cancer survivors tended to be less active compared to people without cancer, there were no statistically significant difference among the three groups. (2) Colorectal cancer (n=17,270, mean age=48.62): MET-minutes/week was 2064.30, 1084.83, and 709.04 36 in groups 1, 2, and 3, respectively. The differences were significant between group 1 and 2 (F=5.87, P=0.016) and group 1 and 3 (F=28.99, P<0.001). Despite potential therapeutic benefits of physical activity, colorectal cancer survivors were less active than peo-ple without cancer in Korea.

Pilates and resistance exercises are used for lumbar stabilization train-ing. However, it is unclear which exercise is more effective for lumbar stabilization. In our study, we aimed to compare surface muscle activity and deep muscle thickness during relaxation and spinal stabilization exercise in experienced Pilates and resistance exercise instructors. This study is a retrospective case control study set in the Exercise Pre-scription Laboratory and Sports Medicine Center. The participants in-cluded Pilates instructors (mean years of experience, 3.20±1.76; n=10), resistance exercise instructors (mean years of experience, 2.53±0.63; n=10), and controls (n=10). The participants performed 4 different sta-bilization exercises: abdominal drawing-in maneuver, bridging, roll-up, and one-leg raise. During the stabilization exercises, surface muscle activity was measured with electromyography, whereas deep muscle thickness was measured by ultrasound imaging. During the 4 stabiliza-tion exercises, the thickness of the transverse abdominis (TrA) was sig-nificantly greater in the Pilates-trained group than the other 2 other groups. The internal oblique (IO) thickness was significantly greater in the Pilates- and resistance-trained group than the control group, during the 4 exercises. However, the surface muscle activities were similar between the groups. Both Pilates and resistance exercise instructors had greater activation of deep muscles, such as the TrA and IO, than the control subjects. Pilates and resistance exercise are both effective for increasing abdominal deep muscle thickness.

This study puts its purpose in identifying the effect of the participation in physical activity-based recreation programs on the optimism of chil-dren, humor styles, and school life adjustment. To achieve the study purpose, this study selected 190 subjects as samples were extracted targeting senior students of elementary schools who participated in the physical activity-based recreation in the metropolitan areas as of 2014. As research methods, questionnaire papers were used and reliability analysis, factor analysis, correlation analysis, and multiple regression analysis were conducted by utilizing SPSS 18.0 after inputting analysis data into the computer. The study results, obtained in this study are as follows: First, in terms of the effect of the participation in physical activi-ty-based recreation programs on optimism, participation frequency and participation intensity would have an effect on optimism, while partici-pation period would have a significant effect on being positive among the sub-factors of optimism. Second, participation in physical activi-ty-based recreation programs might have a significant effect on humor styles. Third, in terms of the effect of the participation in physical activi-ty-based recreation programs on the school life adjustment, it was demonstrated that participation period and participation intensity would have a significant effect on school life adjustment, while participation frequency would have a significant effect on regulation-observance and school life satisfaction.

Horse riding (HR) is a sport harmonized with rider and horse. HR is re-nowned as an effective sport for young and old women and men. There is rare study regarding comparison between elite horse riders and am-ateurs. We aimed to investigate comprehensive ranges of parameters such as change of lactate, heart rate, calorie, VO2max, skeletal muscle mass, body water, body fat, etc between amateurs and professionals to emphasize HR not only as a sport training but also as a therapeutic as-pect. We performed 3 experiments for comparing physical fitness, body compositions, lactate value, heart rate and calorie consumption change before and after riding between amateurs and elites. Around 3 yr riding experienced elites are preeminent at balance capability compared to 1 yr riding experienced amateurs. During 18 min horse riding, skeletal muscle mass and body fat were interestingly increased and decreased, respectively. Lactate response was more sensitive in elites rather than amateurs and its recovery was reversely reacted. Exercise intensity es-timated from heart rate was significantly higher in elites (P<0.05). The similar pattern of calorie consumption during riding between amateurs and elites was shown. Horse riding possibly induces various physiolog-ical (muscle strength, balance, oxidative capability, flexibility, and meta-bolic control) changes within body and is thus highly recommended as combined exercise for women, children, and aged as therapeutic and leisure sport activity.
