Purpose: People who have Down Syndrome (DS) usually have deficiencies in muscular strength, muscular endurance, the development of motor skills, postural control, and gait cycle. These muscular and balance deficits impair daily living activities in people with DS; therefore, attention to improving these factors in various recreational environments seems necessary. Thus, the present study aimed ...
this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...
The aim of this study was to determine the effect of weight transfer training on static and dynamic balance of older women. 20 accessible subjects that met our criteria divided randomly into two experimental and control groups. The experimental group trained for 6 weeks, 3 times a week and each session 60 minutes a day. Biodex balance system used for training and testing procedures. Data analys...
the aim of the present study was to investigate and compare the effects of twokinds of motivational and instructional self–talk on the performance of static anddynamic balance tasks in the elderly. for this purpose, 45 old subjects agedbetween 60 and 70 from qom province participated in this study. static balancetask (stand on one leg) and dynamic balance task (sebt test) were instructed withno...
Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Me...
Background and purpose: Physical activity is one of the components of impulsivity and is one of the risk factors for falls in elderly. In the other words, it causes loss of balance. The aim of this study was to investigate the relationship between impulsivity level in elderly and their ability in maintaining balance. Materials and methods: This cross-Sectional study was performed in 50 elder...
torque, speed, and power as mechanical variables are associated with the functional performance of any rotating machinery. the real-time performance and the efficiency of a machine can be determined with on-line measurement of these parameters. in this investigation a rotary torque meter (transducer) was constructed from strain gauge sensors for measuring the torque of rotating shafts. the syst...
Objectives: Balance is a key component of motor skills ranging from maintaining posture to executing complex sport skills. The aim of this study was to Comparison of static and dynamic balance of athletes of different sports in conditions with and without posture disturbances. Methods: Fort two athletes with 3 years athletic experience (wrestling (n=14, age 19.85±2.79 years, height 177.14±5.17...
Objectives: The goal of this study was to compare the effect of 8 weeks aerobic exercise with resistance training on Brain-derived neurotrophic factor level of old men. Methods & Materials: In this semi-experimental study, a total of 30 elderly men were selected from worldly-wise club of Broujen City, Iran and randomly divided into 3 groups of aerobic training, resistance trai...
