Purpose: This study investigates the influence of elastic resistance exercise using proprioceptive neuromuscular facilitation (PNF) on the daily activities of a patient with incomplete spinal cord injury. The result will be proposed as background data for effective intervention in a patient with incomplete spinal cord injury. Methods: The target subject was a patient with incomplete spinal cord injury to the cervical cord (C6). Elastic resistance exercise based on PNF was performed for 30 min daily, five times a week, for eight weeks. The ASIS motor scale was applied to test the muscular strength of the upper limb, and the spinal cord independence measure II (SCIM II) was used to evaluate the capacity of daily activity. Results: By applying elastic resistance exercise based on PNF, the muscular strength of the upper limb increased and the performance of daily activity improved. Conclusion: Because elastic resistance exercise based on PNF positively influences the ASIA motor scale and SCIM II of the patient with incomplete spinal cord injury. It can be used for training programs to improve the capacity of daily activity of the patient.

PURPOSE: The purpose of this study was to apply dynamic neuromuscular stabilization (DNS) to subjects with forward head posture (FHP) and to compare its effects on respiratory function as against the conventional neck stabilization exercise and neck stretching and extensor strengthening exercises. METHODS: The whole-body posture measurement system was used to measure the degree of FHP, and a spirometer and a respiratory gas analyzer were used to measure the respiratory function. After the intervention was completed, the changes over time were analyzed in the DNS group, the neck stabilization exercise group, and the neck stretching and extensor strengthening exercise group. The inter-group difference in the changes was also analyzed. A repeated ANOVA was performed to compare the respiratory function according to the period between the three groups, and the least significant difference (LSD) method was used for the post hoc test. RESULTS: After the 6-week exercise period, respiratory functions, such as forced vital capacity (FVC), forced expiratory volume for 1 second (FEV1), forced expiratory volume for 1 sec/forced vital capacity (FEV1/FVC), maximum oxygen intake (VO₂max), and the volume of expired gas (VE), significantly improved according to the period (p < .05), but no inter-group differences were found. CONCLUSION: DNS is an effective training method, and can be applied along with neck stabilization exercise and neck stretching and extensor strengthening exercises, which are widely used in clinical practice, to people with FHP who cannot directly perform neck exercises to improve their respiratory function.

Mitochondrial biogenesis-a process that leads to an increment in the number and density of mitochondria, improves physical performance and body health by enhancing exercise capacity. In the present study, we investigated the stimulatory effect of Ashitaba and red ginseng complex (ARC) on exercise capacity in L6 skeletal muscle cells and mice. In L6 skeletal muscle cells, ARC increased the mitochondrial contents and ATP production by activating AMP-activated protein kinase (AMPK), sirtuin 1 (SIRT1), and peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-$1{\alpha}$) and up-regulating the mRNA expression of nuclear respiratory factor-1 (NRF-1) and mitochondrial transcription factor A (TFAM). In the animal experiments, mice treated with ARC showed an increment in exercise capacity as compared with mice treated with Ashitaba extract or red ginseng extract alone. These studies indicate that ARC might serve as a potential natural candidate for enhancing exercise capacity by stimulation of mitochondrial biogenesis.

Purpose: The purpose of this study was to investigate the effects of home exercise program and exercise program of round shoulder adjustments on the level of trapezius muscle activity and attention capacity for middle school students. Method: The participants in this study were composed of 21 middle school students. We made the students lie on the floor in prone position, then measured the height of their acromion from the floor. We chose participants for our study whose measurement values were over 2.5cm. We divided them into two groups, one is for the experimental group, and the other is for the control group. The experimental group exercised three days a week for 6 weeks, including home training, and the control group didn't exercise. We used EMG to measure the trapezius muscle's activity and used a Stroop test for the measurement of the students' attention capacity. Results: The results of our study are as follows. There was no significant difference between the experimental group and the control group. However, there was a significant difference within the experimental group when comparing pre and post training results for Trapezius muscle activity and attention capacity. Conclusion: We found that correcting round shoulder symptom increases the Trapezius muscle activity and students' attention capacity. Future experiments should investigate with systemical management. Also, we need to increase the frequency of the exercise and participants.

The purpose of this study was to investigate the effect of left ventricular diastolic function on exercise capacity in hypertensive patients with obesity compared to the obese group. Adults who visited a general hospital in Gyeonggi-do from 2016 to 2019(man: 308, women: 192) were divided into 4 groups according to hypertension and obesity. In the hypertensive obesity group(IV), the A wave and E/E' wave were significantly higher than the normotensive obesity group(II), and the E' wave was significantly lower(respectively p<0.001). The group IV had significantly lower METS(metabolic equivalents) and exercise duration than the group II(respectively p<0.001). In group IV, E/A ratio was positively correlated with METS(p=0.025) and exercise duration(p=0.026). In contrast, E/E' wave in these groups showed a negative correlation with the exercise duration(p=0.046).

To assess the effect of pinitol supplementation and strength training for two weeks on the anaerobic capacity during and after exercise, and improvement of glucose metabolism during the recovery period of muscular fatigue with repeated acute bouts of cycling exercise, a total of 24 healthy young men were recruited and randomly and equally divided into three groups; pinitol supplementation group (PSG), placebo group (PLG), and control group (CON). Using a randomized double-blinded design, subjects in PSG were provided pinitol supplement, consumed orally 1.2 g/day, and participated in the resistance exercise program and cycling exercise for two weeks. Subjects in PLG underwent the same protocol as those in PSG but consumed the same amount of placebo. No supplementation and exercise program was given to CON. Before and after the intervention, all subjects were tested for their anaerobic capacities evaluated by Wingate test twice separated by 30 min. During the test, peak anaerobic power (PP), mean anaerobic power, total work, and fatigue index were evaluated During resting and recovery, blood samples were drawn and plasma pinitol, myo-inositol, chiro-inositol, insulin, free fatty acid, glucose, and lactate levels were analyzed After two weeks, PP and relative PP of the second biking were improved from the first biking in PSG only (p<0.05). No changes were found in all other variables of Wingate test in all groups. No statistical differences between groups and pre- and post-intervention were observed in concentrations of pinitol, myo-inositol, and chiro-inositol, but pinitol concentration was higher during recovery compared to the baseline in all groups and testings (p<0.05). Lactate level during recovery was higher than the resting level, but no other blood parameters were significantly changed. In conclusion, two weeks of pinitol supplementation in conjunction with short duration of anaerobic training in healthy young men did not induce any obvious benefits in terms of anaerobic capacity and energy metabolism Individual and/or population susceptibility may be one factor responsible for adopting pinitol supplementation.

Purpose: This study examined whether breathing exercises might increase the chest expansion and pulmonary function of stroke patients. Methods: Twenty four patients with stroke were assigned randomly into two groups: a combination of diaphragmatic resistive breathing and pursed-lip breathing exercise (CB) group (n=10) and control group (n=14). The CB group completed a 4-week program of diaphragmatic resistive breathing and pursed-lip breathing exercise. The subjects were assessed using the pre-test and post-test measurements of the chest expansion (length for resting, deep inspiration, deep expiration, deep expiration-inspiration) and pulmonary function (forced vital capacity (FVC), forced expiratory volume at one second (FEV1), FEV1/FVC, peak expiratory flow (PEF), vital capacity (VC), tidal volume (TV), expiratory reserve volume (ERV), inspiratory reserve volume (IRV)). Results: A comparison of the chest expansion between the pre and post tests revealed similar rest, deep inspiration, deep expiration, and deep expiration-inspiration lengths in the CB and control groups (p>0.05). A comparison of the pulmonary function between pre and post tests, revealed significant improvements in the FVC, FEV, PEF, VC, IRV, and ERV in the CB group (p<0.05). There was a significant difference in the FVC, FEV1, PEF, VC and IRV between the 2 groups (p<0.05). Conclusion: These findings suggest that breathing exercise should help improve the pulmonary function, such as the volume and capacity. This suggests that the pulmonary functions of stroke patients might be improved further by a continued respiratory exercise program.

PURPOSE: The purpose of this study was to investigate the effects of passive stretching exercises of the scalene muscles known as respiratory accessory muscles, on forced vital capacity. METHODS: Ten of the participants were randomly selected as an experiment group to perform passive stretching exercises on the scalene muscles. Ten additional students were selected randomly as a control group. The forced vital capacity was assessed by using a digital spirometer (Pony FX, COSMED Inc, Italy) both before and after the passive stretching exercises were performed. Subsequently, passive stretching exercises of the scalene muscles were performed in the experimental group. There were no interventions to the control group. RESULTS: As for the forced vital capacity (FVC), the experiment group showed significant increase in items of forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), peak expiratory flow (PEF), forced expiratory volume in 1 second/vital capacity ($FEV_1/VC$), and maximal expiratory flow 75%(MEF 75%) after the scalenemuscles passive stretching exercises were performed. The control group, however, showed no change. CONCLUSION: This study demonstrated that passive stretching exercises of the scalene muscles could be helpful for forced vital capacity improvement.
