a motor task performance and imagery show several parallel characteristics. in this study, the effect of a voluntary speed change in mental images of a complex difficult sequence of karate techniques on subsequent motor performance was assessed. 24 male karate volunteers (mean age: 24.58±5.27 years) who were well skilled at performing the sequence movements participated in the pretest. during t...
Background: Evaluation of intra-city roads in terms of environmental factors of motor vehicle injuries can help us to better identify these factors and the share of each of the factors in injuries. Therefore, this study was conducted to determine the high injury areas and the risk factors of motor vehicle crashes resulting in injury and death in Tehran, the capital city of Iran, from November...
The aim of this study was to investigate the effectiveness of motor and cognitive dual-task training on dynamic balance of elderly women. For this purpose, 27 old women (aged 60 -82 years) from the old people center of Birjand city were selected randomly and divided into 3 groupd based on their TUG scores. The groups comprised of cognitive dual-task training, motor dual-task training and contro...
Combining the main advantages of the permanent magnet synchronous motors and pure synchronous reluctance motors (SynRM), permanent magnet assisted synchronous reluctance motor (PMaSynRM) has been considered as a promising alternative to the conventional induction motors. In this paper, utilizing a macroscopic design parameter, called insulation ratio along the q-axis, and based on the magnetic ...
Objective: The aim of the present study was to investigate the effect of eight weeks selected sport trainings on perceptual- motor skills among typical obese girls and girls with Down syndrome (aged 7-13). Materials & Methods: In this quasi-experimental study with control group, 22 obese children with Down syndrome and 22 typical obese children who were selected purposefully participated in ...
Background and Aim: Intellectually disabled children have problems in development and motor skills. Thus, the purpose of the present study was to assess the impact of Spark Motor Program on improving of gross motor skills in intellectually disabled educable boys. Materials and Methods: In this semi-experimental study, out of 98 intellectually disabled educable male students studying in schools ...
Objective: Cerebral palsy is the most common chronic motor disability in children and can have negative effect on motor functions. The purpose of this study was to investigate the effect of eight weeks resistance training on gross motor ability, balance and walking speed in a group of such children. Methods: 21 cerebral palsy boys with spastic diplegia, aged between 12 and 16 years (mean, 13...
Objective: The purpose of this study was studying of explicit motor learning in Relapse-Remission (RR) MS patients and compare with healthy subject. Materials & Methods: A serial reaction time task by using software was applied for studying explicit motor learning in 15 RRMS patients and 15 matched healthy subjects. In this task four squares with different colors appeared on the computer scr...
The present research was designed to investigate the cognitive and motor inhibition in persons suffering from obsessive compulsive and schizophrenic disorders and comparing them with a normal group. 90 persons with obsessive compulsive and schizophrenic disorders and normal persons (30 persons in each group) age range between 25-45 were selected. The participants were asked to answer individual...
Cogging torque is the major limitation of axial flux permanent magnet motors. The reduction of cogging torque during the design process is highly desirable to enhance the overall performance of axial flux permanent magnet motors. This paper presents a double-layer magnet design technique for cogging torque reduction of axial flux permanent magnet motor. Initially, 250 W, 150 rpm axial flux brus...
