The purpose of this research is to see how continent specific sports rose to its modern-day status through globalization. This research fo-cuses on the historical background of how England ’s football, America’s national pastime, baseball, Japan’s Judo, and Korea’s Taekwondo de- veloped into sports in addition to the reasoning behind its globalization. Promoted by England and the rest of the European continent, Soccer is considered to be one of the world’s most popular sports and has served its function as a form of cultural imperialism. It has also advanced alongside commerce, missionary work and other types of cultural clashes. In America, baseball was used to integrate its multicultural so-ciety and developed so that the team captain leads the rest of his team. The sports of Oriental countries were reborn through modernization that was influenced by the modern rationality, education etc. of its Western counterparts. Judo and Taekwondo were introduced globally through the Olympic Games. As mentioned above the birth of sporting events has a close connection to a nation’s cultural background and globalization has taken different forms depending on which continent it originated from.

Physical activity plays an important role in preventing further progres-sion of metabolic syndrome conditions to cardiovascular disease and type-2 diabetes. This study investigated physical activity disparities by socioeconomic status among metabolic syndrome patients. The fifth Korea National Health and Nutrition Examination Survey (2010–2012) data were analyzed (n=19,831). A revised definition of the US National Cholesterol Education Program Adult Treatment Panel III was used for screening metabolic syndrome patients. Using International Physical Activity Questionnaire, physical activity adherence was defined as par-ticipating in 150+ minutes of moderate-intensity physical activity, 75+ minutes of vigorous-intensity physical activity, or an equivalent combi-nation of moderate- to vigorous-intensity physical activity per week. Socioeconomic status was measured by level of education and house-hold income. Among metabolic syndrome patients, physical activity ad-herence rate of first (lowest), second, third, and fourth quartile house-hold income group were 28.31% (95% confidence interval [CI], 26.14–30.28%), 34.68% (95% CI, 32.71–36.70), 37.44% (95% CI, 35.66–39.25), and 43.79% (95% CI, 41.85–45.75). Physical activity adherence rate of groups with elementary or lower, middle-school, high-school, and college or higher education degree were 25.17% (95% CI, 22.95–27.54), 38.2% (95% CI, 35.13–41.00), 39.60% (95% CI, 38.24–41.77), and 36.89% (95% CI, 35.77–38.03), respectively. This study found that physical activity adher-ence rate was lower in socioeconomically disadvantaged metabolic syndrome patients, which may aggravate health inequity status of Ko-rean society.

Since there is lack of up to date consensus exists as to whether group training is effective in improving lumbopelvic pain (LPP) after pregnan-cy, a review of the recent evidences is needed. To determine the effect of group exercise training for the management of LPP among pregnant women compared with usual antenatal care. An electronic database search for relevant randomized control trials published in English from 2006 to 2015 was conducted. Articles with outcome measures of self-reported LPP, visual analogue scale and sick leave due to LPP after pregnancy were included. Quality of the included articles was rated us-ing Physiotherapy Evidence Database (PEDro) scale and the pooled ef-fect of self-reported LPP was obtained by Review Manager (RevMan 5) software. Significant effect of group training was detected over usual antenatal care or no treatment with P=0.0035 (95% confidence interval, -0.2348 to -0.0044). The results of this systematic review proposed that group training reduces LPP significantly better than routine antenatal care for pregnant women suffered from LPP.

This study investigated the association between spinal alignment, mo-bility of the hips and the thoracic spine and low back pain in adolescent cross-country skiers. Cohort of 51 elite cross-country skiers from a cross-country skiing high school in Sweden participated in the study. Sagittal spinal alignment, active range of motion in flexion, extension and rotation of the thoracic spine as well as passive and active exten-sion of the hips were measured. The participants also completed a questionnaire regarding training, competition, skiing technique and oc-currence of low back pain. A simple linear regression was calculated to predict pain score based on thoraco-lumbar relation, with a significant (P<0.05) regression equation of y=-0.069x+2.280 (standard error of esti-mate, 0.034). Participants with greater lordosis than kyphosis were more likely to suffer from low back pain than subjects without this off-set. Thoracic mobility and passive or active hip extension showed no correlation with low back pain. Sagittal spinal alignment seems to be related with low back pain among young elite cross-country skiers. This study shows that range of motion of the thoracic spine and hips do not have an effect on the prevalence of low back pain in this population.

This study was conducted on Korean male high school soccer players who underwent anterior cruciate ligament reconstruction (ACLR) to identify the effects of an accelerated rehabilitation exercise (ARE) pro-gram on knee joint isometric strength, thigh circumference, Lysholm score, and active balance agility. We assigned eight test participants each to a physical therapy group (PTG) and an accelerated rehabilita-tion exercise group (AREG), and compared differences between the groups. Both the PTG and AREG showed significant increases in 30° away and 60° toward isometric strength after treatment. In addition, significant differences were observed in these strength tests between the two groups. Both groups also showed significant increases in thigh circumference, Lysholm score, and active balance agility after treat-ment, but no significant differences were observed between the two groups. We conclude that the ARE treatment was more effective for im-proving isometric strength of the knee joint than that of physical thera-py, and that an active rehabilitation exercise program after ACLR had positive effects on recovery performance of patients with an ACL injury and their return to the playing field.

The purpose of this study is to investigate the effect of the long-term aerobic exercises on cardiac structure, left ventricular stroke volume, and cardiac output. To achieve the purpose of the study, a total of 22 volunteers—including 10 people who have continued regular exercis-es and 12 people as the control group—were selected as subjects. With regard to data processing, the IBM SPSS Statistics ver. 21.0 was used to calculate the mean and standard deviation, and the difference of the means between the groups was verified through an independent t-test. As a result, there were significant differences between groups in the left ventricular end-diastolic internal dimension, left ventricular end-systolic internal dimension, left ventricular end-diastolic septum thickness. There were significant differences between groups in left ventricular end-diastolic volume, left ventricular mass, and left ventric-ular mass index per body surface area. However, in cardiac function, only left ventricular stroke volume showed a significant difference be-tween groups.

The purpose of this study is to investigate the effects of strenuous exer-cises on resting heart rate, blood pressure, and maximal oxygen uptake. To achieve the purpose of the study, a total of 30 subjects were select-ed, including 15 people who performed continued regular exercises and 15 people as the control group. With regard to data processing, the IBM SPSS Statistics ver. 21.0 was used to calculate the mean and stan-dard deviation. The difference of mean change between groups was verified through an independent t-test. As a result, there were signifi-cant differences in resting heart rate, maximal heart rate, maximal sys-tolic blood pressure, and maximal oxygen uptake. However, the maxi-mal systolic blood pressure was found to be an exercise-induced high blood pressure. Thus, it is thought that a risk diagnosis for it through a regular exercise stress test is necessary.

Athletes and coaches believe that adequate sleep is essential for peak performance. There is ample scientific evidence which support the conclusion that sleep loss seems to stress many physiological functions in humans. The aim of this study was to determine the effect of one night’s sleep deprivation on intermittent exercise performance in the evening of the following day. Ten male Taekwondo players performed the Yo-Yo intermittent recovery test (YYIRT) in three sleep conditions (reference sleep night [RN], partial sleep deprivation at the beginning of night [PSDBN], partial sleep deprivation at the end of night [PSDEN]) in a counterbalanced order, allowing a recovery period ≥36 hr in between them. Heart rate peak (HRpeak), plasma lactate concentrations (Lac) and rating of perceived exertion (RPE) were measured during the test. A significant effect of sleep restriction was observed on the total distance covered in YYIRT (P<0.0005) and Lac (P<0.01) in comparison with the RN. In addition, performance more decreased after PSDEN (P<0.0005) than PSDBN (P<0.05). Also, Lac decreased significantly only after PS-DEN (P<0.05) compared with RN. However, there were no significant changes in HRpeak and RPE after the two types of partial sleep depriva-tion compared to RN. The present study indicates that short-term sleep restriction affect the intermittent performance, as well as the Lac levels of the Taekwondo players in the evening of the following day, without alteration of HRpeak and RPE.

The aim of the present study was to determine whether 1 week of train-ing cessation can affect exercise performance in well-trained soccer players. Upon the completion of a competitive season, 11 male soccer players went through 1-week training cessation. Performances in the 5-m (1.05±0.04 sec vs 1.02±0.03 sec, P=0.03) and 10-m (1.79±0.06 sec vs 1.74±0.06 sec, P=0.03) sprints were significantly increased after 1 week of detraining with a trend for an increase in the 20-m sprint per-formance (3.07±0.06 sec vs 3.02±0.07 sec, P=0.06). However, the re-peated sprint performance (total sprint time [45.7±2.6 sec vs 48.0±2.6 sec, P=0.01] and fatigue index [5.8%±2.8% vs 7.8%±3.2%; P=0.04]) were reduced. In addition, no significant differences were observed for the 30 m (4.23±0.06 sec vs 4.24±0.09 sec, P=0.63), agility (right: 8.08±0.17 sec vs 8.03±0.37 sec, P=0.54; left: 8.05±0.21 sec vs 8.04±0.30 sec, P=0.84), coordination (13.98±1.21 sec vs 14.06±1.34 sec, P=0.75), Yo-Yo intermittent recovery level 2 (1,040.0±291.8 m vs 1,134.5±232.7 m, P=0.08), and knee extensors and flexors peak torques at all applied an-gular velocities (P<0.05) after detraining. These results indicate that short-term detraining for well-trained soccer players has a significant effect on the speed endurance performance. It is therefore important for the players and their coaches to plan a suitable training program to maintain exercise performance especially speed endurance during off-season.

The aim of this study was to investigate the motor ability of forelimb ac-cording to on- or off-riding during cadences (walk and trot) of horse. Horses and rider selected as subject consisted of total 37 heads of Jeju native horse and 1 female rider. The variables analyzed composed of 1 stride length, 1 step length, elapsed time of stance, elapsed time of swing, elapsed time of 1 step, and forward velocity (x-axis). Two-way analysis of variance of variables was employed for the statistical analy-sis with the level of significance set at 5% (P<0.05). Trot cadence showed significant difference with the faster and shorter during trot than that of walk in velocity and elapsed time. When analyzed interac-tion effect in stance and swing phase, the locomotion showed the shorter elapsed time in trot than that of walk, but more delayed in case of on-riding during stance phase, whereas the case of on-riding showed with the shorter during swing phase than that of the case of off-riding These result of horse’s analysis meant that there was very close relation among variables of rider’s weight-velocity-stride length-stride elapsed time. Next study will be necessary to analyze cadence variables added both stride length and rider’s weight for riding activity and rehabilitation during horse riding using Jeju native horse.
