چکیده

Compensation for the downhill turning moment of a wheelchair on a 2-degree side slope results in retarding force approximately equal to the rolling drag of a wheelchair on a level surface. The total drag force on the wheelchair while transversing a sloping surface is, therefore, roughly double the rolling drag. In contrast, the net energy cost of propulsion on this side slope is only 30 percent greater than for a level surface. Side slope propulsion is managed by "dragging" the uphill rim while pushing the downhill rim. Although this results in increased mechanical efficiency through greater use of a smaller muscle mass, it is more difficult and tiring for the wheelchair user.

بررسی تغییرات فاکتور رشد شبه انسولینی یک (IGF-I)، کورتیزول سرم و عملکرد بازیکنان زن بسکتبال با ویلچر به دنبال 8 هفته تمرین قدرتی بالاتنه

Background & Aims: Wheelchair basketball players rely on upper body strength. It is well established that strength training potentiates muscle hypertrophy and improves strength. But the anabolic and catabolic effects of upper body strength training have not yet been studied in female wheelchair basketball players. Therefore, the aim of this study was to investigate the effect of a 8 week u...

Effects of ramp slope on physiological characteristic and performance time of healthy adults propelling and pushing wheelchairs

[Purpose] This study examined the effects of ramp slope (1:12, 1:10, 1:8, and 1:6) on physiological characteristics and performance times of wheelchair users and the performance times of caregivers to determine which slope would be the best for wheelchairs, in order to propose a ramp slope that incorporates a universal design. [Subjects and Methods] Twenty-four healthy subjects were enrolled in...

Effects of Seated Postural Stability and Trunk and Upper Extremity Strength on Performance during Manual Wheelchair Propulsion Tests in Individuals with Spinal Cord Injury: An Exploratory Study

Objectives. To quantify the association between performance-based manual wheelchair propulsion tests (20 m propulsion test, slalom test, and 6 min propulsion test), trunk and upper extremity (U/E) strength, and seated reaching capability and to establish which ones of these variables best predict performance at these tests. Methods. 15 individuals with a spinal cord injury (SCI) performed the t...
