The purpose of this study was to apply Special Olympics (SO) move-ment and its curricula events to the social rehabilitation of the students with intellectual disabilities in Korean special school. SO is the sport or-ganization for the people with intellectual disabilities enjoyed by the athletes more than 4.4 million in 170 countries. The role of SO has been expanded and its value was increased in effecting social change and promoting social contact between the people with intellectual disabili-ties and the individuals without disabilities. Many researchers proved the effects of SO program for the individuals with intellectual disabilities to become physically and mentally appropriately fit to the society, there-fore, those programs could be the educational resources in Korean special school.

This research discusses the effects of the integrated resorts centered around casinos being implemented in Korea. It particularly focuses on the symptoms and most recent definitions of gambling addiction such as physiological or psychological dependence from excessive gam-bling. This paper suggests that there is a high prevalence rate of patho-logical gambling in Korea. It provides an argument for prevention, early detection, and lastly, active and voluntary treatment. Furthermore, the study addresses the physiological pathway of gambling addiction and the physiological factors of gambling addicts to suggest exercise reha-bilitation that are currently limited to psychological treatments.

Brain-derived neurotrophic factor (BDNF) and its receptors tyrosine ki-nase B (trkB), and cyclic adenosine monophosphate response element binding protein (CREB) have been suggested as the neurobiological risk factors causing depressive disorder. Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in the pathogenesis of depression. We in-vestigated the effect of treadmill exercise on social interaction in rela-tion with BDNF and 5-HT expressions following stress in rats. Stress was induced by applying inescapable 0.2 mA electric foot shock to the rats for 7 days. The rats in the exercise groups were forced to run on a motorized treadmill for 30 min once a day for 4 weeks. Social interaction test and western blot for BDNF, TrkB, pCREB, and 5-HT1A in the hippo-campus were performed. The results indicate that the spend time with unfamiliar partner was decreased by stress, in contrast, treadmill exer-cise increased the spending time in the stress-induced rats. Expres-sions of BDNF, TrkB, and pCREB were decreased by stress, in contrast, treadmill exercise enhanced expressions of BDNF, TrkB, and pCREB in the stress-induced rats. In addition, 5-HT1A receptor expression was de-creased by stress, in contrast, treadmill exercise enhanced 5-HT1A ex-pression in the stress-induced rats. In the present study, treadmill exer-cise alleviated stress-induced social interaction impairment through enhancing hippocampal plasticity and serotonergic function in the hip-pocampus. These effects of treadmill exercise are achieved through 5-HT1A receptor activation.

Regular running and strength training are the best ways to improve aer-obic capacity and develop the size of skeletal muscles. However, un-controlled physical activities can often lead to an undertraining or over-training syndrome. In particular, overtraining causes persistent fatigue and reduces physical performance due to changes in the various phys-iological and immunological factors. In this study, we gave an exhaus-tive submaximal endurance or resistance exercise to participants and investigated the relationship between physical stress (cortisol level in blood), oxidative stress (intracellular ROS accumulation), and adaptive immune response (CD4:CD8 ratio). Ten male volunteers were recruited, and performed a submaximal endurance or resistance exercise with 85% of VO2max or 1-repetition maximum until exhaustion. Blood sam-ples were collected at rest, and at 0 and 30 min after the exercise. Corti-sol levels, oxidative stress, and immune cell phenotypes in peripheral blood were evaluated. Cortisol levels in the sera increased after the ex-haustive endurance and resistance exercises and such increments were maintained through the recovery. Intracellular ROS levels also in-creased after the exhaustive endurance and resistance exercises. The ratio of CD4+ T cells to CD8+ T cells after each type of submaximal ex-ercise decreased compared with that at the resting stage, and returned to the resting level at 30 min after the exercise. In this study, an exhaus-tive endurance or a resistance exercise with submaximal intensity caused excessive physical stress, intracellular oxidative stress, and post-exercise immunosuppression. This result suggests that excessive physical stress induced temporary immune dysfunction via physical and oxidative stress.

The purpose of this study was to examine beach volleyball players’ ex-perience regarding shoulder injury and how it affects their return to play. To achieve the research aims a qualitative design with semi-struc-tured interviews had been conducted, five elite beach volleyball play-ers, four men and one woman aged 27-42 participated in the study. All participants had suffered a severe shoulder injury, with absence from training and competing for at least 28 days. The findings of this study in-dicate that it is the individual´s inner motivation, together with a clear goal and support from the community, family, teammate and coach that are the most important factors when going through rehabilitation and getting back to playing beach volleyball after a shoulder injury. All par-ticipants had been affected by their injury in some way; some of the participants had been affected in a positive way since they had become mentally stronger and had developed better volleyball technique after rehabilitation. The conclusions of this study indicate that there are three distinct factors that increase the chances of getting back to playing beach volleyball after shoulder injury; it is the players´ self motivation, together with a clear goal and support from the community.

The purpose of the present study is to evaluate the effects of isometric exercise types on low back pain (LBP) patients. Isometric exercise types were mat exercise and I-Zer exercise. Subjects were divided into 3 groups: LBP control group, LBP mat exercise group, and LBP I-Zer ex-ercise group in 23-25 aged men. Visual analogue scale (VAS) and elec-tromyography (EMG) were used to evaluate the degree of pain and the muscle activity in LBP patients. Root mean square (RMS), median fre-quency (MDF), and mean frequency (MNF) were checked by EMG pow-er spectrum analysis on longissimus thoracic (LT), iliocostalis lumborum (IL), mulitifidus (M), and rectus abdominis (RA). LBP mat exercise pro-gram and LBP I-Zer exercise program were conducted 5 sets once time, 3 times per week during 6 weeks. The two-way ANOVA with repeated measure was used to check the pain degree and muscle activity. The present results showed that muscle activity in the LBP I-Zer exercise group was increased compared to the LBP mat exercise group and LBP control group (P<0.05). LBP I-Zer exercise group and LBP mat exercise group showed increased mean frequency in LT, IL, M, and RA muscles than the LBP control group. Therefore, LBP patients performed isomet-ric exercise may have positive effect to reduce pain degree and to in-crease muscle activity. Especially, LBP I-Zer exercise type showed more effectiveness in reducing pain degree and enhancing muscle activity.

Frailty is a disorder of multiple inter-related physiological systems. It is unclear whether the level of physical performance factors can serve as markers of frailty and a sign. The purpose of this study was to examine the relationship between frailty and physical performance in elderly women. One hundred fourteen elderly women participated in this study, their aged was from 65 to 80. We were measured 6-min walk test, grip-strength, 30-sec arm curl test, 30-sec chair stand test, 8 foot Up- and Go, Back scratch, chair sit and reach, unipedal stance, BMI, and the frailty with questionnaire. The collected data were analyzed by descrip-tive statistics, frequencies, correlation analysis, ANOVA, and simple lin-er regression using the IBM 21. SPSS program. In results, statistic tests showed that there were significant differences between frailty and 6-min walk test, 30-sec arm curl test, 30-sec chair stand test, grip-strength, Back scratch, and BMI. However, we did not find significant differences between frailty and 8 foot Up- and Go, unipedal stance. When the subjects were divided into five groups according to physical performance level, subjects with high 6-min walk, 30-sec arm curl test, chair sit and reach test, and high grip strength had low score frailty. Physical performance factors were strongly associated with decreased frailty, suggesting that physical performance improvements play an im-portant role in preventing or reducing the frailty.

The current study had three aims: (1) to validate a Korean version of the Student Athletes’ Motivation toward Sports and Academics Question-naire (SAMSAQ-Kr), (2) to examine South Korean university stu-dent-athletes’ motivation towards athletic and academic achievement, and (3) to identify the relationship between athletic identity and their athletic and academic achievement. A total of 126 South Korean univer-sity student-athletes (41.4% males and 58.6% females; mean age 20.5, SD = 2.74) completed the SAMSAQ-Kr. To investigate the validity evi-dence of the SAMSAQ-Kr a confirmatory factor analysis (CFA) and Rasch model were employed. To examine the relationship between Athletic Identity Measurement Scale (AIMS) and SAMSAQ for Spear-man correlation coefficients were calculated. Findings indicated that the SAMSAQ-Kr showed a different model from other versions and re-vealed positive correlations between AIMS scores and athletic motiva-tions. The current study highlighted that importance of considering so-cio-cultural context in developing questionnaire and contributed to help understand South Korean university student-athletes’ motivation to-wards athletic and academic achievement.

Although instrument playing-based training has been repeatedly report-ed to improve functional hand movements including grasping, the at-tempts to present quantitative information on physiological mechanism of grasping have been relatively insufficient to determine the type and the intensity of the exercises involved. This study aimed to examine the muscle activation during hand percussion playing depending on the grasping type and the playing tempo. A total of twelve healthy older adults with a mean age of 71.5 yr participated in this study. Surface electrodes were placed on three grasping-related muscles: Flexor digi-torum superficialis, extensor digitorum, and flexor pollicis brevis. Partic-ipants were instructed to play with the egg shaker, paddle drum mallet and clave involving different types of grasp at three different tempi (i.e., 80, 100, and 120 bpm) and sEMG data were collected during each play-ing. Significantly greater muscle activation was generated with the small sphere type of egg shaker, compared to the handle type of paddle drum mallet and the small cylinder type of clave. Playing at faster tempo also elicited significantly greater muscle activation than at slower tem-po. With regard to the rise time of muscle activation, while tempo sig-nificantly affected the rise time, the time to peak muscle activation did not significantly change depending on the grasping type. This study confirmed that grasping pattern and the tempo of movement signifi-cantly influence the muscular activation of grasping involved in instru-ment playing. Based on these results, clinical implication for instrument selection and structured instrument playing would be suggested.

Retained surgical gauze that was left inside the patient during a surgi-cal procedure is called gossypiboma or textiloma. It is a rare complica-tion of surgery commonly seen after abdominal operations. The symp-toms of gossypiboma are non-specific, such as pain, palpable mass and fever, which make clinical diagnosis difficult. We present a case of young female athlete patient with right lower quadrant (RLQ) pain for 1 month, caused by surgical gauze which was retained from previous ce-sarean delivery performed 24 yr ago. Patient with retained surgical gauze can be asymptomatic for a long period. In our case, laparoscopy was used as the diagnostic and therapeutic tool. This report discusses the approach to, and manifestations of gossypiboma which presents a long asymptomatic period.
