Effect of Step Length and Step Period on Walking Speed and Energy Consumption: a Parameter Study
Stability and performance are two main issues in motion of bipeds. To ensure stability of motion, a biped needs to follow specific pattern to comply with a stability criterion such as zero moment point. However, there are infinity many patterns of motion which ensure stability, so one might think of achieving better performance by choosing proper parameters of motion. Step length and step perio...
متن کاملStep length reductions in advanced age: the role of ankle and hip kinetics.
BACKGROUND Aging is associated with a reduction in gait velocity, which is due to a shortened step length. This study investigated the relationship between joint kinetics and step length. METHODS Three-dimensional gait kinematics and kinetics were measured during usual pace gait in 26 older subjects (average age 79) and in 32 young subjects (average age 26). Gait measures were obtained at max...
متن کاملThe effect of knee orthosis on co-contraction values of knee and ankle muscles during running in people with knee deformity in the frontal plane.
Background and Aims: the use of knee orthosis changes the mechanics of running. One of the important biomechanical factors in rehabilitation and injury prevention is co-contraction of knee and ankle joints. Therefore, the aim of the present study was to investigate the effects of knee orthosis on changes in the contraction of knee and ankle muscles during running in people with genu varum. Mat...
متن کاملthe effects of previewing and providing background knowledge on iranian university efl learners’ comprehension of literary and academic texts
abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
15 صفحه اولthe effects of planning on accuracy and complexity of iranian efl students’ written narrative task performance
this study compared the different effects of form-focused guided planning vs. meaning-focused guided planning on iranian pre-intermediate students’ task performance. the study lasted for three weeks and concentrated on eight english structures. forty five pre-intermediate iranian students were randomly assigned to three groups of guided planning focus-on-form group (gpfg), guided planning focus...
