This study intended to examine the process of development and inten-sification of martial arts education in schools of Chosun as courses of health, hygiene, and physical education implemented by the Japanese colonial government that ruled Chosun during the period of ‘Second Si-no-Japanese War’ from 1937 to 1945. During this period, the Japanese colonial government established the ‘Imperial Subjects’ Gymnastics,’ elaborated on the education of health and hygiene in order to lay the foundations for the strengthening of war potential, and intensified the theoretical education and practice of martial arts as an effective means therefore. The education of health, hygiene, and martial arts, imple-mented by the Japanese colonial power with the catchphrase of con-structing robust body, was nothing but a means to construct and control the body of colonial people at its discretion. The thoughts of health, hy-giene, and martial arts, which were presented to students, were rather intended for the cultivation of the subjects devoted to Japanese Empire than for the promotion of health and psychosomatic development of in-dividuals. In particular, along with contemporary society fell into the tur-moil of war, the amusable aspects of martial arts were lost in the edu-cation of martial arts and were replaced with the spirit of Japanese Sa-murai.

Low back pain is a health issue with significant impact to patients and society. This narrative review aims to synthesize the relationship be-tween obesity, low-grade inflammation and low back pain. It is known that a sedentary lifestyle is a risk factor for obesity and related disor-ders. The adipose tissue of obese people secretes a range of cytokines of character pro- and anti-inflammatory, with many molecular effects. In addition, pro-inflammatory cytokines are sensitizers of C-reactive protein (CRP), a marker of acute inflammation that can be linked to the musculoskeletal pain sensation individuals with back pain. Another in-flammatory marker deserves mention, prostaglandin E2. Prostaglandin E2 is important in the process of triggering actions such as pyrexia, sen-sation of pain and inflammation, which are exhibited in low back pain condition. The potential for exercises and physical activity to control these mediators and act as a preventative measure for back pain are important because they work as a nonpharmacological strategy to this target audience. There are two types of exercise discussed in this re-view, the moderate-intensity continuous training and high-intensity in-terval training.

The current study examined the effects of an exercise program on health related physical fitness, self-efficacy, and physical activity levels in adults with intellectual disability. The study used pre- and posttest experimental research design with a control group. Total of 23 adults with intellectual disability were recruited with 12 assigned for the exer-cise group and 11 for the control group, separately. The measures of health related physical fitness included cardio pulmonary endurance (step-test), body composition (bioelectrical impedance analysis), flexi-bility (sit and reach), muscle endurance (sit-up), and strength (hand grip strength). Self-efficacy was measured using the physical self-efficacy scale. Accelerometers were used to measure physical activity levels. All variables were measured and evaluated twice at baseline and at the end of the program. The exercise program consisted of band exercises and rhythmic activity for 90 min, twice per week for 12 weeks. After the intervention, significant improvements were found in the experimental group in muscle endurance, self-efficacy, and physical activity levels. An exercise program may be recommended as a nonpharmaceutical method to improve the health of adults with intellectual disabilities.

Routine medical checkups have been provided by both the govern-ment-led and private hospitals for the purposes of prevention and early detection of diseases. Various studies were conducted with clinical re-sults obtained from both government and private hospital based results. However, results from two types of health checkups have not been conducted. The results should be compared for the prevalence of met-abolic disease in the aspects of socioeconomic status and health care behaviors to observe the pros and cons of two types of health check-ups. Routine health checkup results of the National Health and Nutrition Survey (1,593 men, 2,180 women) and a private hospital (12,823 men, 7,070 women) of the year 2012 were used for the study. Education level and monthly household income were used to assess the socioeconom-ic status. Alcohol consumption, smoking, and International Physical Ac-tivity Questionnaire were used to assess health behaviors. Logistic re-gression analysis was applied (P<0.05). Participants of the private hos-pital had significantly greater household income, education level, amount of physical activity and intensity, and number of nonsmokers. Women showed no differences in the amount of vigorous physical ac-tivity. The prevalence rates of metabolic syndrome showed similar re-sults. Education level, physical activity, and alcohol consumption were significantly associated in men of the government group. Smoking showed significant influence in men of both groups. Education level, al-cohol consumption, and smoking showed significant influence in wom-en of the government group. Participants who conducted govern-ment-led health examinations showed stronger influence of socioeco-nomic level and health behaviors on metabolic syndrome especially in men.

Compliance with a rehabilitation program is significant among athletes following a sports injury. It is also one of the main factors that influence the rehabilitation process; moreover, the outcome is also influenced by the athlete’s motivation. It is primarily an autonomous motivation, result-ing in rehabilitation adherence. The aim of this study was to investigate the perceived motivation of female football players during rehabilitation after a sports injury and the extent to which these motivating factors were autonomous. Qualitative interviews, based on a semistructured interview guide with injured female football players undergoing rehabil-itation, were analyzed using content analysis. The motivational factors that were described were their set goals, social support as well as ex-ternal and internal pressures during rehabilitation. The perceived au-tonomy varied somewhat but overall, they experienced external motiva-tion; therefore, the behavior was not entirely self-determined. Results are expected to provide a better understanding of women football play-ers’ motivation in relation to their rehabilitation; hence, physiotherapists and coaches who are part of the rehabilitation process can contribute by increasing the autonomous motivation, thus, improving the compli-ance and outcome of the rehabilitation.

We investigated the effect of exercise rehabilitation based on fine mo-tor movement for the elderly with mild dementia. Using electroenceph-alogram (EEG), the change of brain wave of them based on fine motor movement and comparing the improvement level of cognitive ability and performance capability in daily living activity was recorded. The subjects were the elderly with mild dementia living in a sanatorium in Incheon city. Mini-Mental Status Examination, activity of daily living (ADL), and the influence on depression were examined. After 8-week exercise program, significant difference in cognitive function and ADL was observed, however, and there was no significant difference in de-pression. In the EEG, there was a significant difference in α-wave. This study suggests the chance to remind the necessity of exercise programs for improving cognitive function and ADL of the elderly with dementia.

Previous experience has shown that school-based taekwondo training in the United States (US) results in many beneficial effect sregarding school education and the physical health of the adolescent participants; of especial significance, the training plays an important role in terms of exercise value and school-life adaptation. To explore this overall effect, a self-administered questionnaire was distributed to 401 adolescents over the age of 10 years. The survey comprisesa total of 29 questions that consist of 17 exercise-value-related questions (general, moral, and status) and 12 questions that are related to school-life adaptation (ad-aptation to teachers, adaptation to academic activities, adaptation to rule compliance, and adaptation to school activities). The survey results show that taekwondo training affects school-life adaptation by helping to improve student morality and by bolstering the students compliance with school rules during their schooling. The exercise value of tae-kwondo training is considered a necessity for US adolescents due to the corresponding educational aspects; in particular, the training plays a very important role in the maintenance of amenable student-teacher and student-peer relationships. From the previously mentioned findings, and if taekwondo teachers train their students carefully with education-al missions in mind, it is expected that taekwondo training will play a very important role in the cultivation of anappropriate education value among US adolescents.

The shoulder is susceptible to disturbances caused by microtraumas due to direct contact of the surrounding skeletal structures or failure of the soft parts of the rotator cuff and other muscles inserted into the gle-nohumeral joint. The purpose of the study was to compare the electro-myographic signal in the stabilizing muscles of the shoulder during the diagonal elevation exercise as recommended by the proprioceptive neuromuscular facilitation (PNF) method and dumbbell exercise. This study is classified as Quase-experiment. Subjects were instructed to perform diagonal standard exercises and the electromyographic signal was detected from pectoralis muscles, middle and upper trapezius of dominant limb in each subject. We observed greater muscular recruit-ment when the PNF method was adopted in comparison with the dumbbell workouts for the trapezius upper and middle fiber muscles and for the major pectoralis (267,30 μv/181,02 μv; 235,76 μv/;164,47 μv; 299,87 μv/148,69 μv; P<0.001). The PNF method promotes a greater re-cruitment of the shoulder dynamic stabilizing muscles during diagonal elevation exercises. Being so, such kinesiotherapeutic technique may be effectively used in the prevention, treatment and rehabilitation of shoulder disorders.

It is important that compensatory lateral movement of the pelvis does not occur during side-lying hip abduction (SHA). The purpose of the present study is to investigate the effects of abdominal hollowing and abdominal bracing during SHA on pelvic lateral rotation (PLR) and the electromyography activity of the gluteus medius, quadratus lumborum (QL), external oblique abdominis (EO) and internal oblique abdominis (IO). A total of 22 healthy male adults participated in the study. The sub-jects performed three conditions in side-lying in random order: SHA with abdominal hollowing (SHA-AH), SHA with abdominal bracing (SHA-AB), and SHA without any condition (SHA-WC). The angle of PLR in SHA-AB was significantly lower compared to SHA-AH and SHA-WC, and angle of PLR in SHA-AH was significantly lower than that in SHA-WC. The muscle activity of the QL was significantly greater for SHA-AB compared to SHA-AH and SHA-WC. The muscle activity of the EO was significantly greater for SHA-AB compared to SHA-AH and SHA-WC. And the muscle activity of the EO for SHA-AH was significantly greater than that for SHA-WC. The muscle activity of the IO was significantly greater for SHA-AH and SHA-AB compared to SHA-WC. Based on these results, we suggest that abdominal bracing increases the muscle activity of QL, EO, and IO, and decreases the angle of PLR compare to abdominal hollowing during SHA.

The nordic hamstring exercise (NHE) is a dynamic lengthening ham-string exercise that requires trunk and hip muscles activation. Thigh muscles activation, specifically hamstring/quadriceps contractions has been previously examined during NHE. Trunk and hip muscles activity have not been enough studied. The aim of this study was to analyze of hip and trunk muscles activity during NHE. Surface electromyography (EMG) and kinematic data were collected during NHE. Ten healthy men with the age range of 21–36 years performed two sets of two repetitions with downward and upward motions each of NHE. EMG activity of fif-teen trunk and hip muscles and knee kinematic data were collected. Muscle activity levels were calculated through repeated measure anal-ysis of variance in downward and upward motions, through Paired t-test between downward and upward motions and gluteus maximus to erector spine activity ratio (Gmax/ES ratio) using Pearson correlation analyses were evaluated. Semitendinosus and biceps femoris muscles activity levels were the greatest in both motions and back extensors and internal oblique muscles activity were greater than other muscles (P<0.05). The decreased Gmax/ES ratio was significantly related to peak knee extension angle in downward (r=0.687) and upward motions (r=0.753) (P<0.05). These findings indicate the importance of synergis-tic muscles and trunk muscles coactivation in eccentric and concentric hamstrings contractions. It could be important for early assessment of subjects with hamstring injury risk.

The aim of the study was to analyze the effect of knee compression bandage and arm swing control on the maximum horizontal distance and ground reaction force variables in standing long jump. Adult male (n=8; mean age, 22.75±1.98 years; mean heights, 1.77±0.03 m; mean weights, 71.82±12.87 kg) participated in the experiment. The results ob-tained from variables of ground reaction force (GRF) in medial lateral, anterior posterior (AP), vertical (V) direction, resultant GRF (RGRF), de-cay rate (%), and maximum horizontal distance (MHD) were as follows; MHD, AP GRF, VGRF, RGRF (AP-V), and ratio of load reduction (%) showed more effective result under both wearing of knee compression bandage and arm swing. In analysis of main effects, MHD, AP GRF, VGRF, and RGRF showed more increased value in case of wearing of knee com-pression bandage than as was not. While arm swing during standing long jump (SLJ) works as important factor to MHD, showed more effec-tive factor in exercise rehabilitation, injury prevention and swell treat-ment etc. in wearing of worn knee compression bandage. Therefore it was assumed that arm swing and wearing of knee compression ban-dage may improve the performance of SLJ. Also, the characteristics of knee compression bandage suggest that it can be a great help for those participating in exercise rehabilitation.

The aims of this work were to compare the performances of male and female cadet and junior judo athletes and to develop classificatory ta-bles to these judo-specific tests for international-level from these ages. Data collected during training camps of male and female cadet and ju-nior judo teams from three nations (Brazil, Serbia, and Spain) were ana-lyzed, totalizing 252 individual results of special judo fitness test (SJFT), and 222 and 208 of dynamic and isometric judogi chin-up tests, respec-tively. Juniors performed better than cadets in the SJFT, with higher number of throws in A, B, C, and total (P<0.001 for all comparisons), lower final heart rate (P=0.021), and lower index (P<0.001), as well as higher relative performance in the dynamic chin-up test (P<0.001). Fur-thermore, male athletes presented better performance compared to fe-male athletes in the SJFT (higher number of throws in A, B and total, and lower index) and in the isometric and dynamic chin-up tests (higher absolute and relative performances) (P<0.001 for all comparisons). Considering these differences, tables were established by sex and age groups, using percentile values. Thereby, each of the parameters of the SJFT (number of throws, heart rate after and 1 min after the test, and SJFT index), as well as absolute and relative results in chin-up judogi tests, were classified by sex and age. These classificatory tables can be useful for judo coaches to monitor specific physical performance during different phases of periodization process.

The aims of this study were to examine the differences in technical as-pects and physical demands between small-size games (SSG; 8 vs. 8) and regular-size games (RSG; 11 vs. 11) in young Korean soccer play-ers. Seventy-nine young soccer players from 6 teams (U-12) volun-teered to participate in the study. The players completed 4 games (2 SSG, 62×51 m, and 2 RSG, 80×54 m) in 2 days. Each game was filmed to evaluate technical actions. Physical demand variables were mea-sured using global positioning system technology. SSG showed signifi-cantly greater numbers of technical plays among 17 variables when compared to RSG (P<0.05). The players covered significantly greater total distance during low-, moderate-, and high-speed running and sprinting in SSG than in RSG (P<0.05). Higher numbers of high-intensity activities (repeated high-intensity efforts, explosive efforts, decelera-tions, accelerations, and sprinting) were observed in SSG compared to RSG (P<0.05). Mean heart rate was also higher in SSG than in RSG (P<0.05). Despite the greater physical demands during SSG, the exer-cise intensity was similar to that reported in previous studies. Therefore, the SSG format applied in the present study can be a suitable official game format for Korean young soccer players, resulting in significantly greater exposure to technical plays without excessive physical de-mands.

The aim of this study was to estimate the immediate effects of plantar vibration, applied to the more affected foot, on balance impairment in patients post-stroke. This pretest-posttest clinical study included 18 pa-tients (13 men) poststroke; mean age 56.0±8.9 years (range, 41–71 years). One session of 5-min vibratory stimuli (frequency, 100 Hz) was applied to the plantar region of the more affected foot of all participants. The plantar vibration significantly improved the Timed UP and Go test (P=0.03, Cohen d=0.15), ankle plantar flexor muscle spasticity (P=0.008), and ankle passive range of motion (P<0.001, Cohen d=0.74). The posturography measures and Functional Reach Test did not im-prove significantly (P>0.05). Vibration stimuli applied to the plantar re-gion of the more affected foot had significant effects on spasticity, ankle passive range of motion and dynamic balance as evaluated by the Timed Up and Go test in patients poststroke. There was no effect on static balance performance. Based on the results, the focal vibratory stimuli applied directly to the plantar region of the more affected foot may be recommended to improve the functional mobility and dynamic balance in patients with stroke.

The apolipoprotein E (APOE) gene has been suggested to be associated with stroke and dementia. However, the effects of exercise training on dementia according to the APOE genotype are not consistent to those reported by previous studies. Therefore, we examined the effects of ex-ercise training on stroke risk factors including blood pressure, lipid pro-files, homocysteine (Hcy) concentrations, and cognitive function ac-cording to the APOE genotype in stroke patients. We examined the stroke risk factors, Hcy, and cognitive function in 28 ischemic stroke pa-tients before and after 6 months of exercise training. After exercise training, body weight, body mass index (BMI), and percent body fat de-creased significantly in both APOE groups. According to the APOE gen-otype, the changes in BMI in the APOE ε4 group higher than those in APOE ε3 group significantly. Total cholesterol (TC), low-density lipopro-tein (LDL)-C, triglyceride (TG), and Hcy decreased and high-density lipo-protein (HDL)-C increased significantly in the both groups. According to the APOE genotype, systolic blood pressure in the APOE ε4 group de-creased, but in the APOE ε3 group increased after exercise training. TC, LDL-C, and TG in the APOE ε4 group decreased more extensively than those in the APOE ε3 group after exercise training. VO2max (maximal oxy-gen consumption) and cognition increased significantly in both groups. Folate acid intake also increased significantly in both groups. The APOE genotype affects variations in the risk factors of stroke after exercise training. However, the Hcy and cognitive function did not differ based on the APOE genotype.

There is considerable overlap in the manifestations of intellectual dis-ability, autism, and developmental disability. We aimed to determine whether students with such disabilities have differences in their motor proficiency. We compared the motor proficiency of 82 students (age, 11 to 20 years) with different severities of intellectual disability (borderline, 11 students; mild, 27 students; moderate, 19 students), developmental disability (15 students), or autism (10 students). The Bruininks-Oseretsky Test of Motor Proficiency, Second edition was used to assess motor skills. The data were analyzed using descriptive statistics, independent t-tests, and analysis of variance. Compared to students with borderline intellectual disabilities, mild intellectual disabilities, or autism, those with moderate intellectual disabilities scored significantly lower on al-most all items regarding motor skill on the Bruininks-Oseretsky Test of Motor Proficiency. The results of this study provide key information for developing exercise programs to improve the motor proficiency and quality of life of children with various developmental disorders.

The purpose of the present study was to investigate whether there is a relationship between the outcome of preseason physical performance tests and the risk of sustaining lower extremity muscle injuries within the same season, in male football players at elite level. This is a cohort study of a male football team (63 players) from the first league in Swe-den. The football players are prospectively followed, in terms of muscle injuries of the lower extremity during five seasons between 2010 and 2014. All muscle injuries were evaluated and diagnosed with ultraso-nography. The following physical performance tests were included: squats, chin-ups, YoYo intermittent recovery level 2, counter movement jump, squat jump, standing long jump, sprint, one leg squat test, and a functional movement screen. A total of 86 muscle injuries occurred during the study period. No significant correlation was found between the results of the physical performance tests and muscle injuries of the lower extremity. None of the evaluated tests predicted the risk of sus-taining muscle injuries of the lower extremity. We conclude that muscle injury risk factors are more complex than solely related to the results of the preseason physical performance tests.

The purpose of this study is to verify the effects of aquatic exercise on the health-related physical fitness, blood fat, and immune functions of children with disabilities. To achieve the aforementioned purpose, the researchers studied 10 children with grade 1 or grade 2 disabilities who do not exercise regularly. The researchers used SPSS 21.0 to calculate the averages and standard deviations of the data and performed a paired t-test to verify the differences in averages before and after an exercise. The study showed significant differences in lean body weight, muscular strength, cardiovascular endurance, flexibility, and muscular endurance. The researchers found statistically significant differences in triglyceride as well as in immunoglobulin G. The findings suggest that aquatic exercise affects the health-related physical fitness, blood fat, and immune functions of children with disabilities.

The purpose of this study is to analyze the differences among the hospi-talized cancer patients on their perception of exercise and physical ac-tivity constraints based on their medical history. The study used ques-tionnaire survey as measurement tool for 194 cancer patients (male or female, aged 20 or older) living in Seoul metropolitan area (Seoul, Gyeo-nggi, Incheon). The collected data were analyzed using frequency analysis, exploratory factor analysis, reliability analysis t-test, and one-way distribution using statistical program SPSS 18.0. The following re-sults were obtained. First, there was no statistically significant differ-ence between cancer stage and exercise recognition/physical activity constraint. Second, there was a significant difference between cancer stage and sociocultural constraint/facility constraint/program con-straint. Third, there was a significant difference between cancer opera-tion history and physical/socio-cultural/facility/program constraint. Fourth, there was a significant difference between cancer operation history and negative perception/facility/program constraint. Fifth, there was a significant difference between ancillary cancer treatment meth-od and negative perception/facility/program constraint. Sixth, there was a significant difference between hospitalization period and positive per-ception/negative perception/physical constraint/cognitive constraint. In conclusion, this study will provide information necessary to create pa-tient-centered healthcare service system by analyzing exercise recog-nition of hospitalized cancer patients based on their medical history and to investigate the constraint factors that prevents patients from actually making efforts to exercise.

The present study was conducted to investigate the effect of ankle strengthening exercise applied on unstable supporting surfaces on the proprioceptive sense and balance in adults with functional ankle insta-bility. As for the study method, 30 adults with functional ankle instability were randomly assigned to an ankle strengthening exercise group and a stretching group on unstable supporting surfaces, and the interven-tions were implemented for 40 min. Before and after the interventions, a digital dual inclinometer was used to measure the proprioceptive sense of the ankle, the Balancia program was used to measure static balance ability, and the functional reach test was used to measure dynamic bal-ance ability. In the results, both proprioceptive sense and static dynam-ic balance ability were significantly different between before and after the intervention in the experimental group (P<0.05). When such results are put together, it can be seen that ankle strengthening exercise ap-plied on unstable supporting surfaces may be presented as an effective treatment method for enhancing the proprioceptive sense and balance ability in adults with functional ankle instability.

This study was conducted to compare the acute effects of radial extra-corporeal shockwave therapy (r-ESWT), ultrasound (US) therapy and home exercise therapy on pain, fatigue, performance and walking dis-tance in women with plantar fasciitis (PF). Fifty-four female patients di-agnosed with PF participated in the study. The patients were randomly divided into 3 groups as r-ESWT and home exercise groups, US and home exercise groups, and only home exercise groups. Patients’ pain and fatigue levels were assessed by using a visual analog scale. Also walking distances, walking speed and plantar flexor muscles perfor-mance were assessed. Patients’ pain at night before bedtime and leg fatigue after the 6-min walking test decreased in the US therapy group in comparison to the other two groups (P<0.05). The 20-m walking speed improved in the US and r-ESWT therapy groups following the treatments (P<0.05) and there was no difference between the groups. After treatment, while the 20-m walking speed was increasing in US and r-ESWT groups (P<0.05), no increase was observed in exercise group. But there was no difference between the 20-m walking speed of 3 groups after treatment (P>0.05). However, all three groups’ com-plaints decreased after treatment. Our study results illustrated that r-ESWT, US, and home exercise therapy have acute effects on the PF treatment and when there is no possibility of practising any treatment to patients, home exercises such as r-ESWT, US treatment are effective therapies for decreasing pain and fatigue levels and improving perfor-mance and walking distance.

The study was undertaken to compare and analyze kinetic variables during downward foot-on according to the foothold heights under inter-rupted-visual information on 25-t cargo truck. Skilled adult male drivers (n=10) engaged in cargo truck driving over 1 year participated in the experiment. The results obtained from cinematographic and ground re-action force data during downward foot-on as follows; First, leg stiff-ness, peak vertical force (PVF) and loading rate showed significant dif-ference as an increase of foothold heights, that is, interrupted-visual in-formation showed greater impulse force than as was not. Second, vari-ables of center of pressure (COP) with interrupted-visual information did not showed difference, but anterior-posterior COP and COP area showed an increasing tendency as an increase of foothold heights. Third, dynamic posture stability index (overall, medial-lateral, anteri-or-posterior, and vertical) showed significant difference as an increase of foothold height, that is, interrupted-visual information showed lower index than as was not. Therefore it will be possible to control success-fully the leg stiffness, loading rate, and PVF when preparing an estimate for air phase time and impulse force through habitual cognition and confirmation at landing during downward foot-on from cargo truck. Identifying these potential differences may enable clinicians to assess type of injury and design exercise rehabilitation protocols specific.
