Mechanisms Underpinning An Improvement In Dynamic Muscle Force Production Following A High-Intensity Warm-Up, Cody J. Wilson
Theses: Doctorates and Masters
The present research explored the mechanisms underpinning the enhancement of voluntary knee extensor torque after (1) extensive task-specific practice, and then (2) brief, intense warm-up exercise (conditioning activity; CA) as part of a complete warm-up routine. The same warm-up was completed in two Experiments (detailed below). In Experiment 1, voluntary (180⁰·s-1; T180) and electrically-evoked (isometric) knee extensor torques and electromyogram (EMG) and muscle temperature (Tm) data were recorded before and after (1) extensive task-specific practice where peak voluntary knee extensor performance was achieved, and (2) two isokinetic CAs matched for total concentric contraction time (CA60: 5 repetitions at 60⁰·s-1 vs. …
