Purpose: Considering the influence of horizontal velocity on many biomechanical characteristics of walking, the purpose of this study was to investigate how inter-lower-limbs local and global asymmetry is influenced by changes in walking speed from slow to fast. Methods: Ground reaction force data and trajectory of attached markers of bilateral lower limbs of 15 right leg-dominant able-bodied ...

the object of this study was evaluation of a walking tractor drawn peanut harvester at different conditions of soil moisture content and forward speed and comparing it with manual harvesting. the evaluation factors for peanut harvester were two levels of soil moisture content and three levels of forward speed. the results revealed that the effect of soil moisture content was only significant on...

the aim of study was to investigate and compare the concentric torque of quadriceps and hamstring muscles and timed-walking test in two groups. thus, one group of healthy subjects and one group of patients with low grade of tibiofemoral osteoarthritis (oa) were selected. concentric torque of quadriceps and hamstring were measured in both groups. besides, pain measurement, timed-walking test, ra...

background: osteoporosis is one of the most common metabolic bone diseases. the purpose of this study was to investigate the effect of a prevention program based on health belief model on osteoporosis among women. methods: in this quasi-case study, 120 patients (60 cases and 60 control), registered under the health centers in fasa city, fars province, iran were selected in 2014. a questionnaire...

objectives: the purpose of current semi-experimental study was a survey on effect abstract  of 16 week walking on psychosocial functioning related to quality of life among 60 to 75 years old men. methods & materials: for this reason, short form of health-related quality of life questionnaire (sf-36) and geriatric depression scale (gds) had been distributed to the subjects at 2 times of pre-test...

background: hypertension is one of the prevalent and dangerous complications of diabetes mellitus. as it is difficult to control hypertension, the necessity of using new techniques such as non-pharmaceutical methods and complementary therapy is doubled. this study aimed to determine the effect of aerobic exercise on the blood pressure of patients with type 2 diabetes. methods: this study was a ...

Visual flow is used to perceive and regulate movement speed during locomotion. We assessed the extent to which variation in flow from the ground plane, arising from static visual textures, influences locomotion speed under conditions of concurrent perceptual load. In two experiments, participants walked over a 12-m projected walkway that consisted of stripes that were oriented orthogonal to the...

dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. this study is aimed to elaborate this notion in the case of three dimensional (3d) walking and extend it f...
