Postpartum depression (PPD) is defined as the depressive symptoms that occur from the moment of delivery until 12 months after delivery. PPD symptoms are closely associated with reduced activity of the se- rotonergic system. Serotonin (5-hydroxytryptamine, 5-HT) plays an im- portant role in the pathogenesis of depression. Tryptophan hydroxylase (TPH) catalyzes the rate-limiting step of 5-HT biosynthesis in the seroto-nergic neurons. Exercise exerts anti-depressive effect on depression patients as well as on animal models of depression. In the present study, the effect of treadmill exercise on PPD was investigated using rats. For this study, open field test for activity and forced swimming test for depressive symptoms, and immunohistochemistry for 5-HT and TPH were conducted. The rats in the exercise groups were forced to run on a motorized treadmill for 30 min once a day for 2 weeks. Activity in the open field test was decreased in the postpartum rats, however, per- forming treadmill running increased activity in the postpartum rats. The climbing time was decreased and the immobility time was increased in the postpartum rats. Treadmill exercise increased climbing time and suppressed immobility time in the postpartum rats. 5-HT and TPH ex- pressions in the dorsal raphe were suppressed in the postpartum rats, and treadmill exercise enhanced 5-HT and TPH expressions in the postpartum rats. Treadmill exercise ameliorated the PPD very effective-ly by enhancing serotonin level.

Cerebral palsy (CP) is a chronic disorder characterized by physical dis-ability and disruption of brain function. We evaluated the effects of treadmill exercise on motor and memory functions in relation with phosphatidylinositol 3-kinase (PI3K)-Akt pathway using CP rat model. Rota-rod test, step-down avoidance task, 5-bromo-2’-deoxyuridine (BrdU) immunohistochemistry, and western blot for synapsin I, postsyn-aptic density-95 (PSD-95), PI3K, Akt, and glycogen synthase kinase-3β (GSK-3β) were performed. CP was induced by maternal lipopolysac-charide (LPS)-injection with sensorimotor restriction. Five weeks after birth, the rats in the exercise groups were made to run on the treadmill for 30 min per one day, 5 times a week, during 4 weeks. Motor and memory functions were impaired in the LPS-induced CP rats and tread-mill exercise increased motor and memory functions in the CP rats. Cell proliferation in the hippocampus was suppressed in the LPS-induced CP rats and treadmill exercise increased hippocampal cell proliferation in the CP rats. Expressions of synapsin I, PSD-95, phosphorylated (p)-PI3K, and p-Akt were decreased in the LPS-induced CP rats and tread-mill exercise enhanced the expressions of synapsin I, PSD-95, p-PI3K, and p-Akt in the CP rats. GSK-3β expression was increased in the LPS-induced CP rats and treadmill exercise suppressed GSK-3β ex-pression in the CP rats. The present results suggest that treadmill exer-cise might improve motor and memory functions through activation of PI3K-Akt pathway.

Sleep deprivation (SD) inhibits normal biorhythms, causing physical and mental problems. To solve the problems caused by SD, fundamental measures are needed. I investigated change of recovery by rest time in psychological aspect after repetitive SD. The mice were divided into four groups: control 24-hr rest after 24-hr SD group, 48-hr rest after 24-hr SD group, and 72-hr rest after 24-hr SD group (n=20 in each group). I carried out SD in the water cage included multiple platforms. Repetitive SD executes for 36 days. I measured weight every week after SD for 6 weeks. To check emotional condition, I carried out intruder-evoked ag-gression test and modified forced swimming test. In the present results, group treated 24-hr rest and 48-hr rest after 24-hr SD showed lower natural aggressiveness and high depression. However, group treated 72-hr rest after 24-hr SD indicated emotional changes to recover the normal conditions. In the weight change, all group showed significant decrease compared to control for 6 weeks. I suggest that appropriate rest time after SD can help to restore emotional change.

The main purpose of the present study was to calculate the probabili-ty—based on a Bayesian approach—to win a medal in the Olympic Games given the athlete is seeded and to verify if the number one ranked athlete has any advantage compared to other seeded athletes concerning his/her chances to be Olympic champion. For this, data from athletes who took part in the London 2012 and Rio 2016 Olympic Games were considered. For males the probability of seeded athletes to win a medal was 41.1% and 42.9%, while for females it was 35.7% and 44.6% at London 2012 and Rio 2016, respectively. Furthermore, the probability of athletes ranked as number one to become Olympic cham-pion among the seeded athletes was 19.5% and 36.8% for males and 32.3% and 36.8% for females in London 2012 and Rio 2016, respectively. Based on these results the cost-benefit of investing human and finan-cial resources to qualify an athletes among the top eight competitors and his/her exposure to competitions—resulting in technical-tactical analysis of the opponent and higher risk of injury—should be carefully analyzed when determining the competition calendar to each athlete.

The aim of this study was to investigate the acute effects of 16 different combinations to cause the postactivation potentiation (PAP) in elite young soccer players. Squat exercise in 4 different intensities (40%, 60%, 80%, and 100% one-repetition maximum [1RM]) was performed and its effects were evaluated in the performance of countermovement jump (CMJ), after 4 different recovery times (1, 3, 5, and 10 min). For this purpose, 25 young soccer players, underwent five experimental ses-sions. At the first session the control to determine 1RM in half-squat was carried out. The following four experimental sessions were com-prised of four intensity combinations with four different recovery inter-vals in order to perform the CMJ test later, randomly determined and with 30-min interval between each combination. The conditions were compared using an analysis of variance with repeated measurements, followed by Bonferroni test, using 5% significance level (P<0.05). The different intensities investigated did not provide significant increases in CMJ height, but significant differences were noted in recovery time, where, at CMJ maximum height, 1-min interval was better than after 3 min (P<0.05), 5, and 10 min (P<0.001). On the average jump perfor-mances, 1-min interval resulted in better results (P<0.001) compared to other intervals. The 10-min recovery resulted in poorer performances compared to the other intervals (P<0.001). Our results indicate that re-gardless the intensity used in the half-squat exercise with elite young soccer players, the 1-min recovery time was more appropriate to pro-mote an increase in vertical jump.

This study aimed to develop an intervention program based on accep-tance and commitment therapy (ACT) for youth taekwondo players. Eight sessions of the ACT program were provided to nine youth tae-kwondo players. The content analysis was conducted for the activities, activity sheets, assignments, and program evaluations. First of all, the results showed that the ACT program changed the participants’ diverse psychological inflexibility a flexible and value-oriented state, which was supported by their positive mood changes after each session. Second-ly, ‘walking meditation,’ ‘a bus driver and a passenger role play,’ and ‘writing a letter to the self’ were positively evaluated according to the analysis on the feedbacks and evaluations on each session and activity. Lastly, overall evaluation on the ACT program indicated that there were changes in a positive attitude, thoughts, and feelings (anger and irrita-tion) toward taekwondo. The most memorable activities were ‘eating meditation,’ ‘breath-counting meditation,’ and ‘welcoming the beggar’ exercise. These results suggest that an intervention program based on the ACT may have a positive impact on anger management for youth.

This study investigated the influence of physical education class (PEC) as an intervention method for aggression, sociality, stress, and physical fitness levels in children from multicultural families. The hypothesis was that participating in PEC would result in reduced aggression and stress and improved sociality and physical fitness in multicultural children. A three-item questionnaire, a body composition test, and physical fitness tests were given three times. Eighty-four subjects were divided into four groups: multicultural children who participated in PEC (multi-PEG, n=12), multicultural children who did not participate in PEC (multi-NPEG, n=13), single-cultural children who participated in PEC (sing-PEG, n=11), and single-cultural children who did not participate in PEC (sing-NPEG, n=12), respectively. Parametric and nonparametric statis-tical methods were conducted on the collected data with a significance level set a priori at P<0.05. After 8 weeks of PEC, fat mass (F=2.966, P=0.045) and body mass index (F=3.654, P=0.021) had significantly dif-ferent interaction effects. In the aspect of interaction effects from phys-ical fitness variables, cardiopulmonary endurance (F=21.961, P=0.001), flexibility (F=8.892, P=0.001), muscular endurance (F=31.996, P=0.001), muscular strength (F=4.570, P=0.008), and power (F=24.479, P=0.001) were significantly improved in the multi-PEG compared to those of the other three groups. Moreover, sociality (F=22.144, P=0.001) in the multi-PEG was enhanced, whereas aggression (F=6.745, P=0.001) and stress (F=3.242, P=0.033) levels were reduced. As conclusion, the PEC re-duced aggression and stress levels, and improved sociality and physi-cal fitness levels after 8 weeks. This study confirmed that PEC for chil-dren from multicultural families can improve psychosocial factors and physical health.

The aim of the present study was to investigate the effects of caffeine (CAF) and carbohydrate (CHO) intake on strength performance and its metabolic and inflammatory responses during concurrent training. Sev-en active males ingested a double-placebo (P), CAF (capsule 5 mg/kg) or CHO (20% maltodextrin solution) supplementation before strength exercise. Participants performed three randomized sessions of 5,000-m high-intensity intermittent aerobic exercise at maximal intensity fol-lowed by strength exercise, performing after the P, CHO, and CAF in-take. The blood samples were collected before (pre) and immediately after concurrent strength exercise (post). We found a similar number of repetitions and total volume in all supplementation groups. There was a main effect of time on glucose, lactate, and interleukin (IL)-6 (P<0.05). When compared the changes between groups (postvalues minus prevalues), there was lower glucose in CAF group when compared to CHO group (CAF= 5.0±10.4 vs. CHO=27.8±20 vs. P=15.1±14, P=0.031) and higher IL-6 levels (CAF=11.9±9.2 vs. CHO=-2.4±1.7 vs. P=4.3± 11.7, P=0.017). There was significant interaction for glucose and lactate (P<0.001). In conclusion, CAF and CHO intake did not improve strength performance during concurrent strength training in active males. How-ever, CAF affected immunometabolic responses.

Most protocols for testing and rehabilitation for recovery and improve-ment of muscular endurance have been set at 180°/sec, 240°/sec, and 300°/sec. These protocols can cause confusion to clinical providers or other researchers. This study was aimed at investigating the optimal isokinetic angular speed for measuring or developing muscular endur-ance after assessing the relationship between cardiopulmonary re-sponses and isokinetic moments. This study was conducted with 31 male and female college students. Graded exercise test and body com-position were measured as well as the isokinetic moments of the knee muscles at three angular speeds: 180°/sec, 240°/sec, and 300°/sec. The specific isokinetic moments of knee muscles that were measured in-cluded: peak torque (PT) and total work (TW) on extensor (e) and flexor (f) of knee joints, which were denoted as ePT180, fPT180, eTW180, fTW180, ePT240, fPT240, eTW240, fTW240, ePT300, fPT300, eTW300, and fTW300 according to the three angular speeds. Spearman correla-tion test was used to examine the relationship between the sum means of cardiopulmonary responses and the variables of isokinetic moments. This study confirmed that the optimal angular speed for testing or train-ing for muscular endurance was 180°/sec, which showed a stronger relationship between cardiopulmonary responses and isokinetic mo-ments. Therefore, this angular speed is recommended for testing and training for muscular endurance of the knee joints.

Stroke patients often use various arm slings, but the effects of different slings on the joint kinematics and muscle activity of the arm in the gait have not been investigated. The effects of joint kinematics and muscle activity in the gait were investigated to provide suggestions for gait training for stroke patients. In all, 10 chronic stroke patients were volun-tarily recruited. An eight-camera three-dimensional motion analysis system was used to measure joint kinematics while walking; simultane-ously, electromyography data were collected for the anterior and pos-terior deltoids and latissimus dorsi. The amplitude of pelvic rotation on the less-affected side differed significantly among the different arm slings (P<0.05). Changes in the knee kinematics of the less-affected side also differed significantly (P<0.05), while there were no significant differences in the muscle activity of the affected arm. In stroke patients, an extended arm sling is more useful than no sling or a flexed arm sling in terms of the amplitude of the rotation of the less-affected pelvic side in the stance phase while walking. The less-affected knee joint is flexed more without a sling than with any sling. All arm slings support the ex-tension of the contralateral knee.

The purpose of this study was to evaluate the effects of core strength-ening combined with pelvic proprioceptive neuromuscular facilitation (PNF) on trunk impairment, balance, gait, and functional ability of chron-ic stroke patients. Twenty-three participants with chronic stroke were recruited and randomly allocated to one of the two groups: core strengthening combined with pelvic PNF (group 1, n=13), and pelvic PNF with trunk flexibility exercises (group 2, n=10). Intervention was given to both groups for 60 min per session 5 times per week for 4 weeks. Performance of both groups was evaluated on Trunk Impair-ment Scale, Tinetti Performance Oriented Mobility Assessment (Tinet-ti-POMA), Balance Evaluation Systems Test (Mini-BESTest), Wisconsin Gait Scale, and Barthel Activities of Daily Living Index prior to and after the completion of the intervention. The comparison between postinter-vention scores of Tinetti-POMA between group 1 (18.76±1.78) and group 2 (16.8±1.87) and Mini-BESTest group 1 (16.15±1.28) and group 2 (14.7±1.41) showed significant difference (P=0.018). The results indi-cated that core stabilisation combined with pelvic PNF was more effec-tive for improving trunk impairment, balance and gait of chronic stroke patients.

In this study, we examine the thickness of the abdominal muscle and its activity during the performance of the three drawing-in methods. The subjects were 20 healthy male and female students in their 20s. Using ultrasonography and electromyography, the experimenter measured the thickness of the transversus abdominis (TrA) muscle, internal oblique (IO) muscle and external oblique (EO) muscle. The ultrasonog-raphy measurements for the drawing-in manoeuver (DI), abdominal bracing, and posterior pelvic tilt (PT) techniques were 0.64±0.20, 0.54±0.15, and 0.46±0.12, respectively, with significant differences for the TrA. The electromyography results of the DI, SA, and PT techniques were 4.35±1.72, 3.00±1.48, and 2.70±1.52, respectively, for the IO. There was a significant difference in the DI, SA, and PT techniques for the EO (5.10±3.30, 3.85±3.89, 2.25±1.29, respectively). The DI method activated the oblique abdominal muscles, but there was no great change in their thickness; the TrA, however, was selectively strengthened through changes in its thickness.

Pulmonary rehabilitation (PR) is part of the recommended management plan of pulmonary hypertension (PHTN) and is important to better quali-ty of life and exercise tolerance. This study aimed at determining effec-tiveness of PR on exercise capacity. Retrospective chart analysis was conducted on patients referred to our PHTN clinic for PR. Patients who had PHTN diagnosed on right heart catheterization (defined by mean pulmonary artery pressure>25 mmHg) and completed a standardized 12-week PR program were considered for the study. Patients’ baseline exercise tolerance was recorded as speed attainable on a treadmill and duration of exercise in minutes. Demographics, age, sex, and oxy-gen use were obtained from chart review. Eighteen PHTN patients (5 male, 13 female; mean age 67.7±11.6 years) were considered for the study (six World Health Organization [WHO] group 1 pulmonary arterial hypertension [33.33%], eight WHO group III PHTH [44.44%], two WHO group IV and two WHO V PHTN [11.11%]). Treadmill speed improved following rehabilitation (1.3 mph [interquartile range {IQR}, 1.0–1.8 mph] to 2.2 mph [IQR, 1.3–2.8 mph]; P<0.0001, Wilcoxon signed rank test). Median exercise time improved (27 min (IQR, 22–30 min) to 30 min (IQR, 24–30 min); not significant. Improvement was defined only as an in-crease in speed or duration, or both. Sixteem of 18 participants im-proved (88.9% [95% exact binomial confidence interval, 65.3%–98.6%). Patients with PHTN benefit from a structured PR program to improve their exercise capacity and should be enrolled in PR programs as part of their management.

The aim of the present study was to investigate the effects of inspirato-ry muscle exercise (IME) on metabolic and hemodynamic parameters, cardiac autonomic modulation and respiratory function of older women with metabolic syndrome (MS). For this, sixteen older women with MS and 12 aged-matched controls participated of the present study. Two days before and 2 days after the main experiment, fasting blood sam-ples (i.e., total cholesterol, triglycerides and blood glucose), cardiac au-tonomic modulation (i.e., heart rate variability), and respiratory muscle function were obtained and evaluated. The sessions of physical exer-cise was based on a IME, which was performed during 7 days. Each session of IME was performed during 20 min, at 30% of maximal static inspiratory pressure. In the results, MS group presented higher levels of triglycerides, blood glucose, and systolic blood pressure when com-pared to control group. IME was not able to change these variables. However, although MS group showed impaired respiratory muscle strength and function, as well as cardiac autonomic modulation, IME was able to improve these parameters. Thus, the data showed that sev-en days of IME are capable to improve respiratory function and cardiac autonomic modulation of older women with MS. These results indicate that IME can be a profitable therapy to counteracting the clinical mark-ers of MS, once repeated sessions of acute IME can cause chronical alterations on respiratory function and cardiac autonomic modulation.

Stretch of tensor fascia lata (TFL) improves range of motion on hip and pelvis and it reported to help reduce low back pain. Accordingly, the purpose of this study was to investigate effects of static stretching us-ing a load on TFL in patients with low back pain. Twenty three subjects were recruited according to the selection criteria. The subjects were randomly assigned to static stretching group (control, n=12), and a static stretching using a load group (experimental, n=11). All group per-formed stretching for 15 min (side for 50 sec per time and a rest for 30 sec) per day in the left side and the right, respectively, for 2 weeks. Be-fore and after the intervention, all groups measured visual analogue scale (VAS), stand and reach test, and the Oswestry disability index (ODI). In the present results, we found that the experimental group showed significant differences in VAS, stand and reach test, and the ODI (P<0.05) in before and after the intervention. Therefore, static stretching using a load can be actively utilized for low back pain pa-tients with shortened TFL.

In sports, there is a constant discussion about the hyper-pronation and supination of the foot during loading and its relation to injuries or dis-comfort. The purpose of the present study was to investigate the possi-ble differences in the subtalar joint in the midstance phase of running, between individuals with Pes Planus and Pes Cavus, after 5 min and 45 min of running. Thirty-four subjects, meeting the requirements for Pes Planus (30 feet) and Pes Cavus (35 feet), according to the criteria for Medial Longitudinal Arch-angle, were included in the study. The calca-neal vertical angle, representing the eversion/inversion of the subtalar joint, was measured using with two-dimensional digital analysis and Dartfish Software with the subjects running barefoot on a treadmill, be-fore and after 45 min of outside running wearing shoes. Both individuals with Pes Cavus and Pes Planus showed a significant increase in the calcaneal eversion (P<0.05) after 45 min of running. Between the groups, there was a significantly greater eversion of the Pes Planus, on the right foot, after 45 min of running (P<0.05) compared to the Pes Ca-vus. The effect of fatigue evident in the present study suggests that fur-ther biomechanical research should be considered when exposing the foot to the repetitive nature of running, conditions most likely responsi-ble for the overrepresented overuse injuries among runners.

This research was performed to identify the incidence of spinal and lower extremity deformity and to identify the relationship of the inci-dence between the physical characteristics. One hundred forty-seven Physical Education major students and 54 nonmajor students partici-pated in this study. Data collecting was performed by questionnaire and visual postural evaluation. The incidences of genu varus (P<0.00001), genu recurvatum (P=0.0007), forward head (P<0.00001), lordosis (P<0.00001), and scoliosis (P=0.0008) were significantly lower in non-major students compared to major students. The incidences of genu varus (P=0.0017), leg length discrepancy (P=0.0015), and forward head (P=0.005) were significantly greater in women than their counterpart. However, in genu recurvatum (P<0.00001), kyphosis (P=0.0001), and lordosis (P=0.0024), the incidences were significantly lower in women. Overweight (body mass index [BMI]>24.5 kg/m2) students showed sig-nificantly high incidence (4.7 times, P=0.0044) in genu varus compared to students with normal BMI, and revealed significantly low incidence in genu recurvatum (P=0.0047) and protruding abdomen (P=0.0002).

To identify the effects of core stabilization exercise on the Cobb angle and lumbar muscle strength of adolescent patients with idiopathic sco-liosis. Subjects in the present study consisted of primary school stu-dents who were confirmed to have scoliosis on radiologic examination performed during their visit to the National Fitness Center in Seoul, Ko-rea. Depending on whether they participated in a 12-week core stabili-zation exercise program, subjects were divided into the exercise (n=14, age 12.71±0.72 years) or control (n=15, age 12.80±0.86 years) group. The exercise group participated in three sessions of core stabilization exercise per week for 12 weeks. The Cobb angle, flexibility, and lumbar muscle strength tests were performed before and after core stabiliza-tion exercise. Repeated-measure two-way analysis of variance was performed to compare the treatment effects between the exercise and control groups. There was no significant difference in thoracic Cobb angle between the groups. The exercise group had a significant de-crease in the lumbar Cobb angle after exercise compared to before ex-ercise (P<0.001). The exercise group also had a significant increase in lumbar flexor and extensor muscles strength after exercise compared to before exercise (P<0.01 and P<0.001, respectively). Core stabiliza-tion exercise can be an effective therapeutic exercise to decrease the Cobb angle and improve lumbar muscle strength in adolescents with idiopathic scoliosis.

The prediction of life-expectancy in terminally ill patients is important both for medical and social reasons but it is widely recognized as being inaccurate. The aim of this study was to investigate the mortality pre-dictors and indicators of life extension among elderly patients in a hos-pice service center. In order to determine the mortality predictors, we investigated the relationship between patients’ cognitive status using the Korean-Mini Mental State Examination & Global Deterioration Scale (K-MMSE & GDS), the patient’s physical function using the instrumental Activities of Daily Living (ADL) score, and the patient’s blood component values. The subjects included 43 men and 57 women with a mean age of 82.4±8.4 years, and a mean nursing period of 11.1±12.2 months. These terminally ill patients were enrolled in a cross-sectional study. All data were collected from paper and electronic charts, and patient in-terviews. A simple correlation analysis was performed to determine the relationship between the variables and to satisfy the normal distribution (P<0.01). The results revealed that the time of death negatively cor-related with ADL score (r=-0.273, P=0.006). However, the K-MMSE & GDS, and the values of blood component such as albumin, gamma-glu-tamic transpeptidase, blood urea nitrogen, and creatinine were not cor-related with the time of death. Consequently, the ADL score might be an important predictor of mortality and life extension in elderly patients. Therefore, in order to improve ADL score, physical exercise and overall fitness may be potential non-pharmacologic methods useful in prevent-ing mortality in elderly people.
