Molecular chaperones are ubiquitous and abundant within cellular en-vironments, functioning as a defense mechanism against outer environ-ment. The range of molecular chaperones varies from 10 to over 100 kDa. Depending on the size, the specific locations and physiological roles of molecular chaperones vary within the cell. Multifunctionality of heat shock proteins (HSPs) expressed via various cyto-stress including heat shock have been spotlighted as a reliable prognostic target bio-marker for therapeutic purpose in neuromuscular disease or cancer re-lated studies. HSP also plays a critical role in the maintenance of pro-teins and cellular homeostasis in exercise-induced adaptation. Such various functions of HSPs give scientists insights into intracellular pro-tective mechanisms in the living body thus HSPs can be target mole-cules to know the defense mechanism in cellular environment. Based on experimental results regarding small to large scaled HSPs, this re-view aims to provide updated important information regarding the mo-dality of responses of intracellular HSPs towards extracellular stimula-tions. Further, the expressive mechanisms of HSPs data from tremen-dous in vivo and in vitro studies underlying the enhancement of the functionality of living body will be discussed.

High-intensity eccentric exercise is known to induce muscle damage leading to inflammatory responses and extracellular matrix (ECM) deg-radation. These degradation processes involve enzymes such as matrix metalloproteinases (MMPs) and tissue inhibitor of metalloproteinases (TIMPs). MMPs are calcium and zinc-dependent proteolytic enzymes that play a role in ECM degradation and recruitment of inflammatory and myogenic cells into the damaged site. In contrast, TIMPs inhibit MMP-induced ECM degradation to maintain normal homeostasis in ECM. Recently, several studies have examined the process of muscle remodeling and the roles of ECM, MMPs, and TIMPs in exercise-in-duced muscle damage. However, the results of these studies are not in-consistent. In the present mini-review, we will discuss the responses of MMP and TIMP to eccentric exercise based on the literature review.

Physical therapy intervention along with nutritional rehabilitation has recently become an inevitable combo after recent evidences suggest-ing a strong interaction between malnutrition and neuro-muscular dis-abilities which contribute to a significant burden in global settings. Re-cent studies confirm that appropriate physical assessment of neu-ro-musculo skeletal system, developmental assessment or cognitive tools along with nutritional assessments followed by exercise rehabili-tation will yield positive results in children with malnutrition. There is an obvious need to make available a simple physical therapy exercise guidelines with simple measure and exercise to be used in resource limited settings of developing countries. The purpose of this clinical commentary is to summarize simple assessment tools to evaluate activ-ity impairment, participation restriction, gross motor activity and simple physical therapy intervention program for children with disability sec-ondary to malnutrition.

Diabetes mellitus is considered as a risk factor for Alzheimer disease. The aim of the present study was to evaluate the possibility whether treadmill exercise ameliorates Alzheimer disease-associated memory loss in the diabetes mellitus. For this study, the effects of treadmill exer-cise on short-term memory and spatial learning ability in relation with Wnt signaling pathway were evaluated using the streptozotocin (STZ)- induced diabetic rats. Diabetes was induced by intraperitoneal injection of STZ. Step-down avoidance task and 8-arm radial maze test were performed for the memory function. Immunohistochemistry for 5-bro-mo-2‘-deoxyridine (BrdU) and doublecortin (DCX) and Western blot for Wnt3 and glycogen synthase kinase-3β (GSK-3β) were conducted. The rats in the exercise groups were made to run on the treadmill for 30 min per one day, 5 times a week, during 12 weeks. In the present results, short-term memory and spatial learning ability were deteriorated by in-duction of diabetes. Treadmill exercise improved short-term memory and spatial learning ability in the diabetic rats. The numbers of BrdU -positive and DCX-positive cells in the hippocampal dentate gyrus were decreased by induction of diabetes. Treadmill exercise increased these numbers in the diabetic rats. Wnt3 expression in the hippocampus was decreased and GSK-3β expression in the hippocampus was increased by induction of diabetes. Treadmill exercise increased Wnt3 expression and suppressed GSK-3β expression in the diabetic rats. The present study suggests that treadmill exercise alleviates Alzheimer disease-as-sociated memory loss by increasing neurogenesis through activating Wnt signaling pathway in the diabetic rats.

Spinal cord injury (SCI) disrupts both axonal pathways and segmental spinal cord circuity, resulting in permanent neurological deficits. Physi-cal exercise is known to increase the expression of neurotrophins for improving the injured spinal cord. In the present study, we investigated the effects of treadmill exercise on locomotor function in relation with brain-derived neurotrophic factor (BDNF) expression after SCI. The rats were divided into five groups: control group, sham operation group, sham operation and exercise group, SCI group, and SCI and exercise group. The laminectomy was performed at the T9–T10 level. The ex-posed dorsal surface of the spinal cord received contusion injury (10 g × 25 mm) using the impactor. Treadmill exercise was performed 6 days per a week for 6 weeks. In order to evaluate the locomotor function of animals, Basso-Beattie-Bresnahan (BBB) locomotor scale was con-ducted once a week for 6 weeks. We examined BDNF expression and axonal sprouting in the injury site of the spinal cord using Western blot analysis and immunofluorescence staining. SCI induced loss of loco-motor function with decreased BDNF expression in the injury site. Treadmill exercise increased the score of BBB locomotor scale and re-duced cavity formation in the injury site. BDNF expression and axonal sprouting within the trabecula were further facilitated by treadmill exer-cise in SCI-exposed rats. The present study provides the evidence that treadmill exercise may facilitate recovery of locomotor function through axonal regeneration via BDNF expression following SCI.

Autism is a complex developmental disorder with impairments in social interaction, communication, repetitive behavior and motor skills. Exer-cise enhances cognitive function, ameliorates motor dysfunction, and provides protective profits against neurodegeneration. In the present study, we evaluated the effect of treadmill exercise on the motor coor-dination and Purkinje cell loss in relation with reactive astrocytes and microglial activation in the cerebellum using valproic acid (VPA)-in-duced autism rat model. On the 12th day of pregnancy, the pregnant rats in the VPA-exposed group received intraperitoneal injections of 600-mg/kg VPA. After birth, the rat pups were divided into four groups: the control group, the exercise group, the VPA-treated group, the VPA- treated and exercise group. The rat pups in the exercise groups were forced to run on a treadmill for 30 min once a day, 5 times a week for 4 weeks. In the present results, motor balance and coordination was dis-turbed by induction of autism, in contrast, treadmill exercise alleviated motor dysfunction in the autistic rats. Purkinje cell loss, reactive astro-cytes, and microglial activation were occurred by induction of autism, in contrast, treadmill exercise enhanced survival rate of Purkinje neu-rons through inhibition of reactive astrocytes and microglia in the autis-tic rats. The present study showed that exercise may provide a potential therapeutic strategy for the alleviation of motor dysfunction in autistic patients.

Intracerebral hemorrhage (ICH) is a severe type of stroke causing neu-rological dysfunction with high mortality rate. Depression is one of the most common complications of ICH. In the present study, the effects of treadmill exercise on ICH-induced depressive symptoms in relation with apoptosis were investigated using rats. ICH rat model was induced by injection of collagenase into the hippocampus using stereotaxic instru-ment. Open field test for activity and forced swimming test for depres-sive symptoms were conducted. Apoptosis in the hippocampus was detected using terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling assay, immunohistochemistry for caspase-3, and western blot for Bcl-2 and Bax. Western blot analysis for 5-hydroxy-tryptamine (5-HT, serotonin) and tryptophan hydroxylase (TPH) in the dorsal raphe was also conducted for biomarkers of depression. In the present results, immobility time was increased and climbing time was decreased by induction of ICH and treadmill exercise inhibited immobil-ity time and increased climbing time in ICH rats. DNA fragmentation and caspase-3 expression in the hippocampal dentate gyrus were en-hanced by induction of ICH and treadmill exercise suppressed ICH-in-duced DNA fragmentation and caspase-3 expression. Bax expression in the hippocampus was increased by induction of ICH and treadmill exercise inhibited Bax expression in the ICH rats. Expressions of 5-HT and TPH in the dorsal raphe were decreased by induction of ICH and treadmill exercise increased expressions of 5-HT and TPH in the ICH rats. In the present study, treadmill exercise ameliorated depressive symptoms through inhibiting apoptosis.

In this study, we explained the effects of compression garment and electrostimulation on athletes’ recovery period by evaluating blood lac-tate and isokinetic peak torque parameters.Twenty volunteers (15.55± 0.51 yr) were included to study. At recovery period, blood samples was taken for lactate values at 0th, 3rd, 5th, 15th, 30th min. The isokinetic strength test was performed on right ankle at 15th min and on the left ankle at 30th min. The same protocol was performed for compression garment on 2 weeks and for electrostimulation on third weeks and re-sults were compared. There wasn’t any significant difference on blood lactate levels within groups. At women; there was not any significant difference on isokinetic peak torques within two groups. but at electro-stimulation usage we found significant increases on right plantar flexion (P<0.1), right dorsal flexion (RDF) (P<0.1) and left plantar flexion (LPF) (P<0.1) values compared to control measurements. At men; with com-pression garment usage, there was significant increase on LPF values compared to control measurements. At electrostimulation usage, we found significant increases on RDF (P<0.1) and left dorsal flexion (P<0.1) values compared to control measurements. During recovery, there is not any beneficial effect seen on blood lactate level within two groups. When compared to passive rest, compression garments and electrostimulation interventions effects on force generation capacity at recovery are statically significant. Also in terms of force generation ca-pacity; usage of electrostimulation during 15 min and compression gar-ments during 30 min were statically more significant.

The purpose of this study was to investigate the effects of an 8-week Taekwondo (TKD) intervention on balance in children with autism spec-trum disorder (ASD). A total of 14 children with ASD participated in this study. Eight children (eight males; mean age, 10.25±2.38 yr) completed TKD intervention (50 min/2 times/8 week), and six children received no intervention serving as controls (five males, one female; mean age, 10.00±2.83 yr). A computed posturography system with a long force-plate (NeuroCom Balance Master) was used to evaluate static (double and single leg stance with various test conditions) and functional bal-ance (step-quick-turn). Balance was measured before and after the in-tervention. A mixed-model analysis of variance showed a significant group by time interaction in single leg stance balance. After the inter-vention, the TKD group displayed a greater improvement in single leg stance balance with eyes closed condition than the control group (P=0.046). Within-group analysis showed that the TKD group signifi-cantly improved single leg stance balance with eyes open condition (P=0.014). In addition, TKD group displayed trends of improvements in double leg stance balance with unstable surface under eyes closed condition (ES=0.83) and step-quick-turn (Cohen d [ES]=0.70). The con-trol group did not show any significant changes in balance outcomes. In conclusion, TKD training can help children with ASD improve their balance. Children with ASD also showed a high rate of adherence (92%) to the TKD training. Our findings suggest that TKD can be a fun, feasible, and effective therapeutic option for balance improvement of children with ASD.

Acute high-intensity physical exercise is known to improve cognitive performance of children, including those with attention-deficit/hyperac-tivity disorder (ADHD). In this work, we investigated the acute effect of an aerobic stretching and moderate-intensity, health and happiness im-proving movement (HHIM) exercise on the cortical activity of children with and without ADHD using electroencephalography (EEG). Children aged 12 to 14 yr with combined-type ADHD and age-matched healthy controls participated in the study, performing two individual movements (n=79, 35 controls) and a single exercise bout (n=45, 18 controls). elec-troencephalographic signals were recorded before and immediately after each movement, and before and after acute exercise under rest-ing conditions, to obtain absolute and relative power estimates for the theta (3.5–8 Hz), alpha (8–12 Hz), sensory motor rhythm (12–16 Hz), and beta (16–25 Hz) bands. After acute HHIM exercise, all children showed significant changes in their relative EEG, mainly in the theta and alpha bands. Individual movements were found to influence relative theta, al-pha and beta, and theta-to-beta ratios. He presents aerobic stretching HHIM exercise has demonstrated acute effect on the cortical activity of children.

The subjects of this research are 30 students of Dong-Eui Institute of Technology in Busan city, who were grouped into two categories after applying the curriculum of the second semester of the freshman year to their classes: those whose academic performance was at the top 20% (15 students) and those whose academic performance was at the bot-tom 20% (15 students). For the measurement items, we measured their weight, body fat mass, body fat rates, body mass index, and abdominal fat rates by using a body composition testing machine. We then ana-lyzed the t-test results by using the IBM SPSS ver. 18.0 program. Through this research, we found that there was a significant difference among those in the group of students whose academic performance was at the top 20% in terms of body fat mass and body fat rates, which means that academic performance has relatively little effect on body composition and abdominal fat rates.

This study aimed to evaluate functional capacities of Cameroonian tu-berculosis (TB) patients in initial intensive phase of treatment using the 6-min walk test (6MWT) and to compare them to an age-matched healthy group. Twenty-eight TB patients newly diagnosed and 19 healthy age-matched peoples participated in the study. Performance parameters were determined using the 6MWT. Anthropometric and cardiorespiratory parameters were measured at baseline and after 6MWT. Two months later, TB patients were submitted to the same eval-uation. We found significant differences in anthropometric parameters between the two groups. The baseline cardiorespiratory parameters and performance characteristics of TB patients were lower than con-trol group (571.7±121.0 m vs 841.6±53.0 m, P<0.0001 for 6-min walk dis-tance (6MWD) and 18.1±2.8 mL/kg/min vs 24.3±1.2 mL/kg/min, P<0.001 for mean VO2 peak (peak oxygen consumption). Two months after, signifi-cant improvements were noted in anthropometric, cardiorespiratory and performance parameters except for bone mass and FEV1/FEV6 (forced expiratory volumes in 1 second/6 seconds) ratio. Significant correlations were found between the 2-min walked distance (P<0.0001, r=0.95), 4-min walked distance (P<0.0001, r=0.97) and 6MWD. In con-clusion, TB patients have impaired physical functional capacity but they improved after 2 months of treatment. 6MWT can be a useful tool in the assessment of physical parameters and cardio-respiratory functional capacity rehabilitation of TB patients during the treatment.

The aim of the present pilot study was to prove if the action-observation (AOb) improved the cervical range of motion (CROM) in patients with nonspecific chronic neck pain (CNP). Double blind pilot study. A total of 28 subjects were randomly assigned to an effective-movement group (n=14) and an ineffective-movement group (n=14). The follow-up con-sisted of: pretreatment, posttreatment and 10 min after second mea-surement (motor imagery). Outcome measures were CROM, and pres-sure pain detection thresholds (PPDTs). No statistical differences were found in baseline on CROM and on the PPDT. Test for independent groups revealed significant changes in cervical rotation movement. Both groups in posttreatment (P=0.042; Cohen d=0.81) and after 10 min (P=0.019; Cohen d=0.9). For intragroup PPDT, the Wilcoxon test re-vealed significant effects in the effective movement at C2 of the pre to 10-min post (P=0.040). However, the ineffective movement revealed a significant reduction in PPDT in zygapophyseal joint of C5–C6 as the pre to post (P=0.010) as the pre to 10-min post (P=0.041) periods. In conclu-sions this pilot study demonstrated that the effective AOb produced sig-nificant changes versus ineffective AOb in the CROM and it could influ-ences in PPT in subject with CNP immediately.

This study is aimed at exploring ideas for the development of Pilates in-structor qualification system by identifying a range of difficulties Pilates instructors are experiencing. Open-ended questionnaires and semi-structured interviews were conducted to collect data before they were analyzed with inductive content analysis method. In consideration of the difficulties Pilates instructors experience during three qualification stages (before-during-after qualification education), three key catego-ries were incorporated in the collected data: (1) lack of information on Pilates qualification system, (2) difficulties in understanding the human anatomy related with the diverse movements taught in Pilates classes and its application to Pilates practice, (3) need for professional develop-ment through retraining. Based on these findings, a need for rethinking the monitoring and evaluation process for Pilates qualification system and Pilates education in Korea was identified. In addition, we need to summarize and offer information on a range of Pilates qualifications. And the quality of Pilates instructor education program should be im-proved as well by proving them a range of teaching methods including microteaching, discussion-based lessons as well as reading and writ-ing sessions and other necessary teaching media.

Ligament laxity measurement is clinically valuable to diagnose the inju-ry and also to compare the laxity before and after surgical procedure. The aim of the study was to compare the accuracy of the Lachman and Anterior Drawer Tests to evaluate the knee examination with the KT1000 arthrometer after the anterior cruciate ligament (ACL) surgery in early follow-up period. Fourty ACL reconstructed knees were examined with the Lachman and Anterior Drawer Tests, and KT1000 arthrometer with compariable intact knee of the same patients. Physical emanina-tion findings were compared with the KT1000 arthrometer with each power. Spearman correlation and receiver operating characteristic (ROC) analysis were used for the evaluation of relations between pa-rameters. Significance was evaluated in P<0.1 and P<0.05. The mean age was 28.18±6.21 yr, and the mean follow-up was 23.09±9.08 months. The mean KT1000 measurements of 40 operated knees state at 6.8, 9.1, 13.6 kg and maxium anterior displacement forces were 4.9, 6.7, 8.7, and 11.9 mm, respectively. The same values for the same acting forces of intact knees were 4.2, 5.9, 7.8, and 10.2, respectively. In Spearman’s cor-relation and ROC analysis at 13.6-kg power on KT1000 arthrometer sta-tistically matched with pyhsical examinations (P<0.1, P<0.01). In our study, correlation of physical examinations with KT1000 arthrometer is a worthy evaluation technique that can be added to examination of ACL reconstructed knee to control with inexperinced examiners’ findings. We suggest that at 13.6-kg power with KT1000 arthrometer findings perfectly match the Lachman and Anterior Drawer Tests of the knee.

This study aimed to analyze an effect of the kinetic variables and pos-tural stability between bilateral in lower limbs by participation of Oreum trekking exercise program and subjects participated were composed of adult male and female subjects (n=14) of 20s. Experiment was per-formed with the drop landing which can evaluate postural stability and kinetic variables between bilateral in lower limbs. peak vertical force (PVF) value showed significant difference with the less in case of post than before participation of Oreum trekking exercise. Also PVF of bilat-eral in lower limbs did not showed significant difference, and too the ef-fect of interaction. vertical stability index (VSI) and dynamic postural stability index (DPSI) showed significant difference with improvement of postural stability by Oreum trekking, but did not between bilateral in the limbs. Particularly the result of one-way analysis of variance due to VSI’s effect of interaction, showed the more influence on the improve-ment of postural stability in left leg after participation of Oreum trekking exercise. When consideration the above, the analysis result on asym-metric index of bilateral in lower limbs showed more symmetric pattern in post than before participation of Oreum trekking exercise program.

Older adults with disability might have been increasing due to the rapid aging of society. Many studies showed that physical activity is an es-sential part for improving quality of life in later lives. Regular physical activity is an efficient means that has roles of primary prevention and secondary prevention. However, there were few studies regarding old-er adults with disability and physical activity participation. The purpose of this current study was to investigate restriction factors to regularly participate older adults with disability in physical activity by employing keyword network analysis. Two hundred twenty-nine older adults with disability who were over 65 including aging with disability and disability with aging in type of physical disability and brain lesions defined by dis-abled person welfare law partook in the open questionnaire assessing barriers to participate in physical activity. The results showed that the keyword the most often used was ‘Traffic’ which was total of 21 times (3.47%) and the same proportion as in the ‘personal’ and ‘economical’. Exercise was considered the most central keyword for participating in physical activity and keywords such as facility, physical activity, dis-abled, program, transportation, gym, discomfort, opportunity, and leisure activity were associated with exercise. In conclusion, it is necessary to educate older persons with disability about a true meaning of physical activity and providing more physical activity opportunities and decreas-ing inconvenience should be systematically structured in Korea.
