The Intensive Diet and Exercise for Arthritis (IDEA) trial: design and rationale
(East Carolina University, 2009-07-28)
Background: Obesity is the most modifiable risk factor, and dietary induced weight loss potentially the best nonpharmacologic intervention to prevent or to slow osteoarthritis (OA) disease progression. We are currently ...
Muscle work is biased toward energy generation over dissipation in non-level running
(East Carolina University, 2008-12-05)
This study tested the hypothesis that skeletal muscles generate more mechanical energy in gait tasks that raise the center of mass compared to the mechanical energy they dissipate in gait tasks that lower the center of ...
Muscles do more positive than negative work in human locomotion
(East Carolina University, 2007-10)
Muscle work during level walking and ascent and descent ramp and stairway walking was assessed in order to explore the proposition that muscles perform more positive than negative work during these locomotion tasks. Thirty ...
How do low horizontal forces produce disproportionately high torques in human locomotion?
(East Carolina University, 2008)
Although horizontal ground forces are only ~15% of vertical forces, they account for 47% and 33% of the metabolic cost in walking and running. To explain these disproportionately high metabolic costs we hypothesized that ...
Teager-Kaiser Operator improves the accuracy of EMG onset detection independent of signal-to-noise ratio
(East Carolina University, 2008)
A temporal analysis of electromyographic (EMG) activity has widely been used for non-invasive study of muscle activation patterns. Such an analysis requires robust methods to accurately detect EMG onset. We examined whether ...
