Background: The purpose of this study was to identify the effects of the blood flow on carotid and vertebral artery during the forward shift on head. Methods: A 20-year female healthy subject participated in this study. This study was set up the forward shift on head at the 3cm and 6cm in a shoulder midline (acromion). Measurement method were using duplex ultrasound with colour doppler imaging for the blood flow on carotid and vertebral artery. Results: Carotid artery was increased the blood flow and vertebral artery was decreased the blood flow during forward shift on head. Conclusions: These findings suggest that carotid and vertebral artery changes to the blood flow during forward shift on head. Therefore, we should be consider that hemodynamic factor when apply to the therapeutic exercise for patients of forward head posture.

본 연구는 노력성 호흡 운동 중심의 촛불끄기 호흡훈련이 성인의 몸통 근력 강화를 의미하는 호흡 능력 향상에 어떤 유의한 효과가 있는지를 알아보기 위하여 실시하였다. 4주간의 촛불끄기 훈련을 통해 실험 전-후의 노력성폐활량(FVC)은 통계학적으로 유의하게 증가하였다(p<.05). 4주간의 촛불 끄기 훈련을 통해 실험 전-후의 1초간 노력성 날숨량(FEV1)의 변화는 통계학적으로 유의한 차이를 보이지 않았다(p>.05). 4주간의 촛불 끄기 훈련을 통해 실험 전-후의 최대날숨유속(PEF)은 유의하게 증가하였다(p<.05). 본 연구는 건강한 성인을 대상으로 노력성 호흡 운동 중심의 촛불끄기 호흡운동을 실시하여 성인의 몸통 근력 강화를 의미하는 노력성 폐활량(FVC), 1초간 노력성 날숨량(FEV1), 최대날숨유속(PEF) 등의 노력성 호흡훈련과 허파기능의 관계에 대해 조사하여 유의한 결과를 얻었다. 앞으로 물리치료가 꼭 필요한 중증 호흡기계 질환자를 대상으로 하는 연구가 진행되어야 할 것으로 사료된다.

Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV₁ showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

Purpose: We investigated to evaluate the effectiveness of water-based exercise (WE) program on respiratory functions for children with spastic diplegic cerebral palsy (CP). Methods: Fourteen children with spastic diplegic CP were randomly assigned, to either the experimental group (EG, n=7), or the control group (CG, n=7). Respiratory function was measured by a spirometer, a CardioTouch 3000S ( Bionet, Seoul, Korea) at a chair-sitting posture. Forced vital capacity (FVC), forced expiratory volume at one second (FEV1), peak expiratory flow (PEF) were measured. The intervention program will last 8 weeks, with three 40 minutes sessions per week (24 training session). The usual care and the addition of a WE program, were compared in the CG and EG, respectively. Results: The EG showed a significant increase in the FVC, FEV1, PEF after training (p<0.05), whereas there was no significant difference in the CP after training. In the EG, FVC increased significantly, compared to the control group (p<0.05), but not FEV and PEF. Conclusion: These findings suggest that WE program have an effect on the respiratory function in children with spastic diplegic CP.

본 연구는 노인에 있어서 입체조 운동의 효과와 만족도의 관계를 조사하기 위해 시행되었다. 47명의 실험군을 12주 동안 주 2회 입체조 운동을 하였고, 39명의 대조군은 물리적 검사를 수행하였다. 타액분비량은 실험군이 0.075 ml로 대조군 0.046 ml보다 높았다. 최대 개구량은 실험군이 4.12 cm로 대조군 3.92 cm보다 높았다. 구강 교호 운동량은 실험군과 대조군이 각각 초당 1.69 회와 1.65 회로 나타났다. Kaiser 정규화와 함께 Quartimax법에 의한 주성분 분석 결과는 입체조 프로그램에 대한 유행 예측도가 높아 노인의 구강건강을 위해 앞으로 입체조 프로그램이 많이 사용되리라 예상이 된다. 상관분석 결과 입체조 프로그램이 타액분비량을 증진시키므로(r=.592) 노인의 구강기능을 증진시키기 위해 적극 권장될 필요가 있다. 입체조를 어려워하는 노인에 대해 좀 더 접근성이 용이하도록 개선할 필요가 있다. 추후 구강운동이 노인의 구강건강 뿐만 아니라 고령화 시대 노인의 건강 증진 방안의 일환으로 적극 활용되어야 할 것이다.

This study investigates the geometrical impact on the nanomedicine drug delivery via nanodevices. A nanomotor made of the nanotube carrying the drug as the motor blade is considered in the blood flow. Physical activities change the blood flow, and sports training enhances the blood flow and plays a significant role in the stability of drug delivery devices. This paper studies the impact of geometrical parameters on the nanomotors carrying the nanomedicine. The effect of physical exercise on the dynamic response regarding the stability of drug delivery devices is discussed in detail.

Purpose: The purpose of this study was to identify the effects of low intensity blood flow restriction training (LBFR) on the central nervous system of healthy adults. Methods: Ten healthy right-handed adults (eight males and two females, mean age of 28.6 ± 2.87 years) were selected as study subjects. Functional magnetic resonance imaging (fMRI) was conducted to measure brain activation (BA) following LBFR and non-LBFR. The primary motor area, premotor area, and supplementary motor area, which are closely related to exercise, were set as the regions of interest. Results: The BA recorded during the LBFR condition was 931.7 ± 302.44 voxel, and the BA recorded during the non-LBFR condition was 1,510.9 ± 353.47 voxel. Conclusion: BA was lower during LBFR than during non-LBFR.

The purpose of this study was to evaluate far-infrared clothing (FIR condition) with non-far-infrared clothing (Control condition) to assess the effects of FIR on thermo-physiological responses. Eight young healthy males (23.0±2.3 yr, 176.5±3.7 cm, and 69.0±4.3 kg) participated in this experimental trial, which consisted of a 20 min rest followed by a 40 min walk (4.0 km·hr^-1) and a 20 min recovery at 20℃ with 50%RH. The results showed that finger skin blood flow and mean skin temperature were significantly higher for the FIR condition than the control during exercise and recovery (p<.001). Clothing microclimate temperature of the FIR condition was 0.5℃ higher on the back (p=.001) and 0.4℃ higher on the thigh (p=.015) during recovery. Clothing microclimate relative humidity of the FIR condition was 13% higher on the chest (p=.006) and 19% higher on the back (p<.001) during exercise than control. Subjects felt warmer and more comfortable in the FIR condition than in the control (p<.05). Perceived skin wettedness (%BSA) was less in the FIR condition than in the control (p=.001). These results indicate that ceramic-embedded clothing had significant effects on thermoregulatory responses for light activity in an indoor environment.

A 2-month-old female Abyssinian cat was presented with a severe ascites, cyanosis, and exercise intolerance. Diagnostic studies revealed V/VI holosystolic murmur, sinus tachycardia, generalized cardiomegaly with marked left atrial enlargement and shunt flow between left and right ventricles. Doppler study showed bi-directional shunts in rest and right-to-left shunt after exercise. Based on clinical signs and diagnostic findings, the cat was diagnosed as a reversed ventricular septal defect. The cat was treated with furosemide, nitroglycerine, dobutamine and oxygen supplement. Despite initial improvement of clinical signs after initiation of medical treatment, the cat died of sudden cardiac arrest. Necropsy revealed a perimembranous ventricular septal defect.
