Preferred speed and cost of transport: the effect of incline.
Preferred speed is the behavioral tendency of animals to utilize a relatively narrow set of speeds near the middle of a much broader range that they are capable of using within a particular gait. Possible explanations for this behavior include minimizing musculoskeletal stresses and maximizing energetic economy. If preferred speed is determined by energetic economy (cost of transport, C(T)), th...
متن کاملEffect of load on preferred speed and cost of transport.
Horses have a tendency to utilize a relatively narrow set of speeds near the middle of a much broader range they are capable of using within a particular gait, i.e., a preferred speed. Possible explanations for this behavior include minimizing musculoskeletal stresses and maximizing metabolic economy. If metabolic economy (cost of transport, CT) and preferred speeds are linked, then shifts in C...
متن کاملRESPONSES OF OXYGEN CONSUMPTION, HEART RATE AND PERCEIVED EXERTION TO CRUTCH WALKING: A COMPARISON BE TWEEN PAR APLEGIC AND ABLE-BODIED SUBJECTS
In this study, 10 normal volunteers and 5 sports-trained paraplegics with lesions between T6 and L2 were studied whilst walking with axillary crutches and knee-anlde-foot orthoses. All subjects walked at their preferred speed on a figureof- eight track. Normal subjects also walked at slower and faster speeds. Oxygen consumption, heart rate and rating of perceived exertion were measured. In...
متن کاملThe Physiological Cost Index and Some Kinematic Parameters of Walking and Jogging in Blind and Sighted Students
Background: Vision plays an important role in supporting efficient locomotion. The present study aimed to measure the physiological cost index (PCI) and some kinematic parameters of preferred walking and jogging in blind and sighted students.Methods: A cross-sectional study was conducted among blind (n=18) and sighted (n=27) students aged 8-16 years. The following parameters were measured...

Background: Spinal cord injuries are among the most common problems originated in human societies. In our country this problem takes into account more seriously when considering the devotees of 8-year imposed war. Materials and methods: After filling the questionnaire and receiving necessary educations, paraplegic patients walked on a course like "figure of 8" with preferred speed for 5 minutes...
متن کاملConstrained optimization in human running.
Walking humans spontaneously select different speed, frequency and step length combinations, depending on which of these three parameters is specified. This behavior can be explained by constrained optimization of cost of transport (metabolic cost/distance) where cost of transport is seen as the main component of an underlying objective function that is minimized within the limitations of speci...
