Physical activity reduces the incidence and progression of cognitive impairment. Cognitive-motor dual-task training, which requires dividing attention between tasks exercise, may improve various domains; therefore, we examined effect training on executive functions plasma amyloid β peptide (Aβ) 42/40 ratio, a potent biomarker Alzheimer's disease, in healthy elderly people. Twenty-seven sedentary people participated 12-week randomized, controlled trial. The subjects assigned to (DT) group...
Background: There are few studies evaluating the distribution of successful ablation sites idiopathic right ventricular outflow tract (RVOT) arrhythmias using a three‐dimensional electroanatomical mapping system. This study aims to clarify favorite site RVOT through voltage CARTO system (Biosense Webster, Diamond Bar, CA, USA). Methods: A consecutive series 72 patients (mean age 43.6 ± 16.2 years, 32 males) who underwent radiofrequency catheter (RFCA) for total 82 morphologies were studied....
The precise incidence and characteristics of ventricular arrhythmias originating from the pulmonary artery have not been fully described. purpose this prospective study was to clarify these points.Thirty-three consecutive patients with an idiopathic left bundle branch block inferior-axis deviation type arrhythmia were included. All underwent detailed electroanatomical mapping (CARTO, Biosense-Webster, Diamond Bar, CA, USA) during sinus rhythm prior catheter ablation. location tip at...
Background: This study aimed to investigate the relationship between muscle mass and effect of contraction tasks leading biceps fatigue on joint drive resistance elbow joint.Methods: A total 23 healthy men were included in this study. tone electromyograph was used measure passive flexion extension before after task. The slope regression line angular torque during motion calculated analyzed as elastic coefficient. We also investigated estimated resistance.Results: Muscle increases coefficient...
[Purpose] The purpose of the present study was to evaluate effect water immersion at different depths on respiratory function and inspiratory load breathing (ILB) during muscle strength evaluated by maximum expiratory pressures (PImax PEmax, respectively). [Subjects] Eight healthy men participated randomly in three trials. [Methods] All sessions were conducted with participants a sitting position immersed bath. We function, PImax PEmax submersion levels depth (umbilicus; 4th-rib; or...
The arrhythmogenic relationship between the presence of J-waves during sinus rhythm and idiopathic ventricular tachycardia (VT) or pre-mature contractions (PVCs) originating from right outflow tract (RVOT) has not been reported. aim this study was to investigate prevalence characteristics RVOT-VT/PVCs associated with J-waves.The enrolled 138 consecutive RVOT-VT/PVC patients undergoing radiofrequency catheter ablation (RFCA) 276 age- gender-matched control subjects. assessed in each cohort,...
The purpose of the present study was to investigate effect walking in water on respiratory muscle fatigue compared with that land at same exercise intensity. Ten healthy males participated 40-min treadmill trials and an intensity 60 % peak oxygen consumption. Respiratory function strength were evaluated before after trials. Inspiratory forced expiratory volume 1 s significantly decreased immediately water, 5 min baseline. decreases inspiratory greater land. In conclusion, induced by than young men.
This study aimed to compare respiratory muscle strength in individuals performing continuous and noncontinuous walking exercises water after the 6-week program. Twenty-nine healthy men were randomly divided into a group (CG, n=14) (NG, n=15). Firstly, both groups executed program which set them walk for 30 min, 4 times per week, over 6 weeks pool with adjusted intensity that their speed increased heart rate 60% of predicted maximum. After program, participants CG continued water-walking...
[Purpose] This study aimed to examine the influence of social-networking service usage via smartphone on internet addiction and psychological stress in Japanese university students studying physical therapy. [Participants Methods] single-university cross-sectional involved 247 therapy second fourth years (ages 19 22). By use self-administered questionnaires, we collected information daily time usage, smartphone, self-learning outside class hours. We assessed using Internet Addiction Test...
A 58‐year‐old man was referred to our emergency room with hemodynamically unstable sustained ventricular tachycardia (VT). The morphology of the VT exhibited a left bundle branch block and inferior axis deviation. He had no past history cardiovascular disease. Echocardiography, cardiac catheterization, biopsy, gallium scintigram, myocardial T1,T2‐weighted magnetic resonance imaging (MRI), gadolinium‐enhanced cine MRI did not detect any structural heart disease or abnormal function. However,...
Kyphosis may reduce the force of coughing by affecting factors related to cough peak flow (CPF). This study sought compare strength and respiratory function between non-kyphotic kyphotic elderly individuals clarify relationship these factors.The group comprised 17 with a kyphosis index less than 15.1, while 21 15.1 or higher. Cough strength, function, muscle maximum phonation time were measured, comparison two groups correlation analysis variables performed.CPF, vital capacity, expiratory...
