Quantification of activity during wheelchair basketball and rugby at the National Veterans Wheelchair Games: A pilot study.

30 Aug 2009 To date, no published data exists on distances and speeds traveled by rugby or basketball players during game play. The purpose of this study was to provide quantitative information of selected characteristics of wheelchair basketball and rugby game ... Read more...

Fatigue-related changes in fascicle-tendon geometry over repeated contractions: difference between synergist muscles.

30 Aug 2009 Fatigue-induced changes in force production of synergist muscles were evaluated through observation of fascicle-tendon geometry and electromyography (EMG). Seven subjects performed 60 maximal isometric plantar flexions intermittently. No ... Read more...

Upper limb effort does not increase maximal voluntary muscle activation in individuals with incomplete spinal cord injury.

19 Aug 2009 OBJECTIVE: To determine the effect of upper limb effort on maximal lower limb muscle activation in individuals with incomplete spinal cord injury. METHODS: Fifteen individuals with incomplete spinal cord injury performed recumbent stepping using ... Read more...
