Purpose: The purpose of the present study was to investigate the effects of a simultaneous dual-task and horse-riding simulator (HRS) training regime on pulmonary function and flexibility. Methods: Sixteen subjects were recruited and randomly allocated to two groups: a dual-task (DT) (n=8) or a single-task (ST) (n=8) training group. Flexibility and pulmonary function were assessed before and after HRS training. Both groups underwent HRS training for 4 weeks, 3 times/week in 15-minute training sessions. The ST group underwent HRS training and the DT group underwent dual-task HRS training, which consisted of throwing and catching a ball and ring catching while HRS training. Results: Training significantly increased flexibility and FVC (forced vital capacity) and FEV1 (forced expiratory volume in 1 second) in both groups (p<0.05), but FEV1/FVC and PEF (peak expiratory flow) were not significantly different after training in both groups (p>0.05). After the training, flexibility and FVC in the DT group were significantly greater than in the ST group (p<0.05), but FEV1, FEV1/FVC, and PEF were not significantly different (p>0.05). Conclusion: Simultaneous dual-task and HRS motor training improved flexibility, FVC, and FEV1, and our comparative analysis suggests that dual-task HRS training improved flexibility and FVC more than single-task training.

Purpose : The purpose of this study was to study the effect of rectus abdominal muscle contraction by proprioceptive neuromuscular facilitation trunk stabilization training using extremity simultaneous pattern (PNF trunk stabilization training) and traditional trunk stabilization training methods. Methods : A group of 24 adults male and female, healthy, with no previous medical history nor disability in neuromuscular system and musculoskeletal system was chosen as subjects, and was divided into a control group, a PNF trunk stabilization training group and a traditional trunk stabilization training group. Experiments were performed on the last two groups, 3 times a week for 6 weeks, totaling 18 times. Using a dynamometer, muscle strength and endurance time on trunk flexion were measured before and after each experiment, and surface electromyography in left and right rectus abdominis were measured. Results : following results were obtained; 1. As for the change in the maximal voluntary isometric contraction (MVIC), all subjects in the trunk stabilization training group showed significant difference from those in the control group. 2. As for surface electromyography measurement and the changes in root mean square at the time of trunk flexion, in the left rectus abdominis, PNF trunk stabilization training group showed significant difference from the control group, while in the right rectus abdominis, traditional trunk stabilization training group showed significant difference. Conclusion : To sum up the results, both trunk stabilization training groups showed improvement in the MVIC of abdominal muscle, motor unit action potential activity, but the difference between two trunk stabilization training groups was not significant. Therefore, while trunk stabilization training significantly improved abdominal muscle contraction, but the difference attributable to training methods was found to be insignificant.

Purpose : This study examined the effect of transcranial direct current stimulation (tDCS) combined high intensity interval training (HIIT) on the aerobic exercise capacity of college soccer players. Methods : The subjects of this study were 30 college soccer players. They were divided into a high intensity interval training group combining transcranial direct current stimulation (Group I) and a high intensity interval training group (Group II). Each group had 15 subjects randomly assigned. After receiving general soccer training, each group additionally received high intensity interval training combined with transcranial direct current stimulation and high intensity interval training for 30 minutes 5 times a week for 8 weeks. Their VO₂max and 20 meter shuttle run test, Yo-Yo intermittent recovery test were analyzed before the intervention. After 8 weeks of intervention, the above items were re-measured and an intergroup analysis was performed. Results : As a result of comparative analysis of VO₂max intake between groups, 20 meter shuttle run test and Yo-Yo intermittent recovery test, a statistically significant difference was found. The high intensity interval training group (Group I) combined with transcranial direct current stimulation showed a significant difference in aerobic exercise capacity compared to the high intensity interval training group (Group II). Conclusion : These results showed that high intensity interval training group combined with transcranial direct current stimulation was more effective for aerobic exercise. Based on this study, this study proposes an effective program for patients as well as elite athletes. In the future, it is necessary to develop an effective transcranial direct current stimulation program and to study how to apply it for various patients.

Purpose : The purpose of this study was to examine the effect of task-oriented circuit training using unstable support surface on balance, gait ability, and balance confidence in subacute stroke patients. Methods : Forty-five patients with subacute stroke were randomly divided into the three following groups of 15: 1) TOCT-US group; task-oriented circuit training using unstable surface (experimental group 1), 2) TOCT-SS group; task-oriented circuit training using stable surface (experimental group 2), and 3) CON group; conventional physical therapy (control group). All patients participated in one of the three training programs for 6 weeks, 30 minutes per session, 3 times per week. Patients' balance ability was assessed using the BT-4, BBS (berg balance scale), TUG (time up and go test), and LOS (limit of stability). Gait speed was measured to examine gait ability. K-ABC (activities-specific balance confidence scale) was also used to assess the level of patients' confidence in daily activities. Results : After the intervention, the sway area in experimental groups 1 and 2 decreased, but that in the control group increased. Experimental group 1 showed significant improvement compared with experimental group 2 and the control group. BBS, TUG, and LOS scores of experimental group 1 were significantly improved compared with those of experimental group 2 and the control group. Also, gait speed significantly improved in experimental group 1 compared with experimental group 2 and the control group. Experimental groups 1 and 2 showed significant improvement in K-ABC scores after training. Conclusion : Patients with subacute stroke had significantly improved balance, gait, and level of confidence in performing activities of daily living following task-oriented circuit training using the unstable surface. This indicates that task-oriented circuit training using unstable surfaces can be an effective treatment method for the recovery of balance and gait in subacute stroke patients.

Purpose: The purpose of the study was to assess the effects of proprioceptive neuromuscular facilitation (PNF) training and respiratory muscle endurance training on pulmonary function and activity in chronic stroke patients. Methods: The participants were 25 chronic stroke patients. They were assigned to two groups: a PNF and respiratory muscle training group (experimental group; n = 12) and a conservative training group (control group; n = 13). The experimental group completed 50 minutes (30 minutes of conventional physical therapy, 10 minutes of PNF training, and 10 minutes of respiratory muscle endurance training). The control group also completed 50 minutes (30 minutes of conventional physical therapy and 20 minutes on a full-body workout machine). Pulmonary function and activity were measured before and after the intervention, using Cosmed to analyze pulmonary function and 6MWT as clinical evaluation indicators. Results: Both groups showed significant within-group differences on all tests before and after the intervention; the experimental group showed greater improvement on all tests. Conclusion: The findings confirm that PNF training and respiratory muscle endurance training have a positive effect on pulmonary function and activity index in chronic stroke patients.

Objective : This study is conducted to find the influence on upper extremity function, cognitive function and activities of daily living when stroke patients receive task-oriented training in group or individually. Methods : Twenty-six inpatients are assigned to two groups(task training group and individual training group) randomly, who receive rehabilitation therapy after stroke diagnosis for 5 months(june to november, 2012) in a hospital. Both groups receive a task-oriented training for 30 minutes a day for 3 weeks. FMA were used to measure upper extremity function, K-MMSE were used to measure cognition, and MBI for ADL. Results : Before training. two groups were not different significantly in upper extremity function and cognitive function. But in activities of daily living, bathing self(p<.001), feeding, personal hygiene and total score(p<.05) are higher in group training group. After training, upper extremity function is higher in individual training group(p<.001). In both training group, upper extremity function, feeding, personal hygiene, bathing self, dressing, toilet, chair/bed transfers, ambulation and stair climbing, total score are improved significantly(p<.05). In comparing of variation before and after training, upper extremity function(p<.001), feeding and total score of activities of daily living are more improved significantly in individual training group(p<.05). Conclusion : The outcome shows that task-oriented training can improve upper extremity function and activities of daily living in both training group. Especially, the more upper extremity function is improved, the more activities of daily living is improved. In the future, it will be necessary longitudinal study for a long time for more patients.

Purpose : This study is to examine the effects of different task-related circuit training by types of tasks on the depression and quality of life in stroke patients. Method : Forty-four chronic stroke patients were divided into a dual motor circuit task training group, a dual cognitive circuit task training group and a simple task training group. Over the course of eight weeks, before training, all the patients were identically encouraged to receive conservative physical therapy for 30 minutes, five times a week for a total of eight weeks with individual additional tasks. The dual motor circuit tasks training consisted of continuous circuit training motor tasks and additional motor tasks and the dual cognitive circuit task training consisted of tasks combining the same circuit training motor tasks and additional cognitive tasks. The simple task training consisted of natural walks on a flat terrain to the front, rear and lateral sides of the terrain. Result : As for the Stroke-Specific Quality of Life(SS-QOL) that showed significant diffe rences in comparison between the groups over the training period, the dual motor circuit task training group showed statistically significant differences in both different types of tasks at 8 weeks(p<.05). The score of Hospital Anxiety and Depression Scale(HADS) decreased in three groups, in the HADS showed significant changes over the training time in the three training groups(p<.05). Conclusion : It could be seen that the practical and continuous dual circuit task training was more effective than simple task training on quality of life. In comparison between the types of dual tasks, the dual motor circuit task training group showed more effects than the dual cognitive circuit task training group. This researcher hopes that the results of this study will be actively applied as rehabilitation methods for chronic stroke patients.

The effects of Physical exercise, gymnastics and sports on the cardiopulmonary function were studied in the middle and high school toys. The subjects were divided into 4 groups; non-training group and training group in both middle school and high school boys. In the above groups, pulmonary function studies were performed, and blood pressure and the heart rate were also checked to evaluate physical fitness during and immediately after running exercise on the tread-mill, with the speed of 5 MPH and elevation of 9% and 11.25%. The types of sports in the training group were base ball, body building, Taekwondo (Korean style boxing) and hand ball. The results obtained were as followings: 1) In the training group, cardiopulmonary function showed some tendency of the increase comparing to the non-training group. 2) The increase in cardiopulmonary function was observed according to the age became older, but the clear changes on cardiopulmonary function was not observed as the difference of the group between the training and the non-training. 3) The expiratory volume was decreased as the increase of age except 17 years of age for the value of the per kg body weight. 4) In the non-training group, the mean value of oxygen consumption under maximum work load was increased, while those in the training group was decreased. But it may be noted that oxygen consumption for the expiratory volume was increased in the training group, and that the oxygen cost in the training group was .higher than that of the non-training group. 5) The pulse pressure of the high school group during and immediately after running exercise was observed in the higher value comparing with that of the middle school group It was suggested that the changes of the pulse pressure was owing to the method of determination and that to the decrease of diastolic pressure caused by the decrease of peripheral vascular resistance up to critical closing pressure. 6) Any differences of the changes in the heart rate between the training group and non-training group was not observed during and immediately after running exercise. 7) The relative value of the expiratory volume to the heart rate was decreased in the elder age group.
