Activity-induced muscle injury and dysfunction have been identified as key components of musculoskeletal injuries. These injuries often occur following eccentric contractions, when the muscle is under tension and stretched by a force that is greater than the force generated by the muscle. Many daily activities require muscles to perform eccentric contractions, including walking (or running) downhill or down stairs, lowering heavy objects, and landing from a jump. Injuries often occur when these activities are performed at high intensity or for prolonged periods of time. General features of eccentric-induced muscle injury are well documented and include disruption of intracellular muscle structure, prolonged muscle weakness and dysfunction, a delayed-on-set muscle soreness, and inflammation. Several weeks are required for the affected tissue to fully regenerate and recover from eccentric-in-duced muscle injury. Possible mechanisms responsible for eccentric-in-duced muscle injury are activation impairment and structural disruption of the sarcomere. These two factors seem to be the main sources of ec-centric-induced muscle injury. Rather than being separate mechanisms they may be complimentary and interact with each other. Therefore, in this review we will focus on the two main cellular mechanism of muscle cell injury following accustomed eccentric contraction.

Emotional disorder is psychological and behavioral problems of emo-tional domain that is different from cognitive domain, such as thought and memory. Typical emotional disorders are anxiety disorder, depres-sion, and bipolar disorder. In the present study, we discussed on the symptoms, progression, and treatment for the anxiety disorder (panic disorder, social phobia, and obsessive compulsive disorder), depres-sion, and bipolar disorder. The goal of treatment for the emotional disor-der is removal of symptoms. In spite of the development of brain science, removal of symptoms, prevention of recurrence, and coming back to normal life require patience and effort.

During pregnancy, diabetes mellitus exerts detrimental effects on the development of the fetus, especially the central nervous system. In the current study, we evaluated the effects of postnatal treadmill exercise on short-term memory in relation with cell proliferation and apoptosis in the hippocampus of rat pups born to streptozotocin (STZ)-induced dia-betic maternal rats. Adult female rats were mated with male rats for 24 h. Two weeks after mating, the pregnant female rats were divided into two groups: control group and STZ injection group. The pregnant rats in the STZ injection group were administered 40 mg/kg of STZ intraperito-neally. After birth, the rat pups were divided into the following four groups: control group, control with postnatal exercise group, maternal STZ-in-jection group, and maternal STZ-injection with postnatal exercise group. The rat pups in the postnatal exercise groups were made to run on a treadmill for 30 min once a day, 5 times per week for 2 weeks beginning 4 weeks after birth. The rat pups born to diabetic rats were shown to have short-term memory impairment with suppressed cell proliferation and increased apoptosis in the hippocampal dentate gyrus. Postnatal treadmill exercise alleviated short-term memory impairment by increased cell proliferation and suppressed apoptosis in the rat pups born to dia-betic rats. These findings indicate that postnatal treadmill exercise may be used as a valuable strategy to ameliorate neurodevelopmental prob-lems in children born to diabetics.

Schizophrenia is a severe mental disorder characterized by abnormal mental functioning and disruptive behaviors. Abnormal expression of N-methyl-D-aspartate (NMDA) receptor, one of the glutamate receptor subtypes, has also been suggested to contribute to the symptoms of schizophrenia. The effect of treadmill exercise on schizophrenia-in-duced apoptosis in relation with NMDA receptor has not been evaluat-ed. In the present study, we investigated the effect of treadmill exercise on neuronal apoptosis in the hippocampus using MK-801-induced schizophrenic mice. MK -801 was intraperitoneally injected once a day for 2 weeks. The mice in the exercise groups were forced to run on a treadmill exercise for 60 min, once a day for 2 weeks. In the present re-sults, repeated injection of the NMDA receptor antagonist MK-801 re-duced expression of NMDA receptor in hippocampal CA2-3 regions. MK-801 injection increased casapse-3 expression and enhanced cyto-chrome c release in the hippocampus. The ratio of Bax to Bcl-2 was high-er in the MK-801- induced schizophrenia mice than the normal mice. In contrast, treadmill exercise enhanced NMDA receptor expression, suppressed caspae-3 activation and cytochrome c release, and inhibited the ratio of Bax to Bcl-2. Based on present finding, we concluded that NMDA receptor hypofunctioning induced neuronal apoptosis in MK-801-induced schizophrenic mice. Treadmill exercise suppressed neuro-nal apoptosis through enhancing NMDA receptor expression in schizo-phrenic mice.

Trekking includes downhill walking and enhances lower limb strength. Muscle fitness is a predictor of mortality and is associated with cardio-vascular risk factors in adults. The purpose of this study was to investi-gate the effects of trekking on cardiovascular health and fitness in older obese women. The participants were randomly assigned to an exercise group (EG, n=32) and a control group (CG, n=48). The EG participated in the trekking program for 12 weeks, 3 times per week, and 90 min per session, at a moderate intensity. Cardiovascular health (BMI, percent-age of body fat, blood pressure, glucose, triglycerides, and total choles-terol) and fitness (muscle strength, muscle endurance, balance, and flexibility) were measured before and after the 12-week program. A two-way repeated ANOVA was used to compare and analyze the group dif-ferences. Body weight, systolic blood pressure, and muscle strength were significantly different between the groups. These results indicate that trekking played a significant role in the reduction of weight and sys-tolic blood pressure in obese women. The results of this study can be utilized to reduce cardiovascular risk factors associated with aging.

This study investigated the reliability of ultrasound in combination with surface electromyogram (EMG) for evaluating the activity of the abdom-inal muscles in individuals with and without low back pain during the abdominal drawing-in maneuver (ADIM). The study recruited ten indi-viduals with or without low back pain, respectively. While the partici-pants were performing the ADIM, the activities of the transversus ab-dominis (TrA) and the internal oblique (IO) were measured using ultra-sound, while the activities of the external oblique (EO) and the rectus abdominis (RA) were measured using surface EMG. Intra-class cor-relation coefficients (ICC) were used to verify the inter-rater reliability of ultrasound in combination with surface EMG at rest and during the ADIM, and Bland-Altman plots were used to verify intra-rater reliability. The inter-rater reliability for the two groups at rest and during the ADIM was excellent (ICC2,1=0.77-0.95). In the Bland-Altman plots, the mean differences and 95% limits of agreement in the abdominal muscles of the two groups at rest were -0.03~0.03 mm (-0.66 to 0.60 mm) and -0.12~ -0.05 (-0.58 to 0.48% MVIC), respectively. The mean differences and 95% limits of agreement in the abdominal muscles of the two groups during the ADIM were -0.04~0.02 mm (-0.73 to 0.65 mm) and -0.19~0.05% MVIC (-1.24 to 1.34% MVIC), respectively. The ultrasound in combination with surface EMG showed excellent inter-rater and intra-rater reliability at rest and during the ADIM.

The purpose of this study is to investigate the effect of exercising pro-gram utilizing proprioceptive neuromuscular facilitation integration pat-tern (PIP), which is effective in improvement of the physical function, on the fall efficacy and gait ability of the elders who experienced injuries from falls. Also, this study aims to investigate he applicability of exercise program as methods for fall reoccurrence prevention and physical functions enhancement. The subjects of the study were 30 elders in the local community with experience of injuries from falls. The period of the study was 4 weeks with 12 exercise sessions. The subjects were ran-domly allocated to 2 groups where 15 elders were allocated to PIP and the rest 15 elders were allocated to general exercise (GE) group. Fall ef-ficacy scale (FES) and GAITRite were used for the measurements in this study. Paired t-test was used to analyze the differences within the group while independent t-test was used to analyze the difference be-tween two groups. In the comparison of measurements before and af-ter exercise program, FES, velocity, cadence, and stride length were shown to be significantly increased in both PIP group and GE group. Also, in the comparison between two groups after the exercise pro-gram, the measurements of FES, cadence, stride length, and step length in PIP group were shown to be significantly increased compared to the GE group. Therefore, the PNF combined pattern is judged to be applica-ble to as methods for fall reoccurrence prevention and physical func-tions enhancement of the elders with experience of being fallen.

Controlling pain in patients with fractured ribs is essential for preventing secondary complications. Conventional medications that are adminis-tered orally or by using injections are sufficient for the treatment of most patients. However, additional aggressive pain control measures are needed for patients whose pain cannot be controlled effectively as well as for those in whom complications or a transition to chronic pain needs to be prevented. In this study, we retrospectively analyzed the medical records of patients in our hospital to identify the efficacy and characteristics of intercostal nerve block (ICNB), as a pain control method for rib fractures. Although ICNB, compared to conventional methods, showed dramatic pain reduction immediately after the proce-dure, the pain control effects decreased over time. These findings sug-gest that the use of additional pain control methods (e.g. intravenous patient-controlled analgesia and/or a fentanyl patch) is recommended for patients in who the pain level increases as the ICNB efficacy de-creases.

This study investigated age-related changes of cognitive function in Korean adults using the Korean-Developmental Test of Visual Percep-tion-2 (K-DTVP-2) and the Visual Motor Integration-3rd Revision (VMI-3R) test, and determined the main factors influencing VP and VMI in older adults. For this research, 139 adults for the K-DTVP-2 and 192 adults for the VMI-3R, from a total of 283 participants, were randomly and separately recruited in province, Korea. The present study showed that the mean score of the K-DTVP-2 and VMI-3R in 10-yr age incre-ments significantly decreased as age increased (K-DTVP-2, F=41.120, P<0.001; VMI-3R, F=16.583, P<0.001). The mean score of the VMI-3R and K-DTVP-2 were significantly decreased in participants in their 50s compared to those in their 20s (P<0.05). Age (t=-9.130, P<0.001), gen-der (t=3.029, P=0.003), and the presence of diseases (t=-2.504, P= 0.013) were the significant factors affecting K-DTVP-2 score. On the oth-er hand, age (t=-6.300, P<0.001) was the only significant factor affect-ing VMI-3R score. K-DTVP-2 score (Standardized β=-0.611) decreased more sensitively with aging than VMI-3R (Standardized β=-0.467). The two measurements had a significant positive correlation (r =0.855, P< 0.001). In conclusion, it can be suggested that VP and VMI should be regularly checked from an individual’s 50s, which is a critical period for detecting cognitive decline by aging. Both the K-DTVP-2 and VMI-3R could be used for determining the level of cognitive deficit by aging.
