LECTURE 6 Flashcards
Two challenges for motor control researchers, coaches, teachers, practitioners…
Develop and disseminate new, valid, reliable knowledge appropriate for audience.
Interpret new knowledge with respect to evaluating, understanding and improving human motor performance.
Validity
The degree to which a test measures what it purports to measure
Measures of validity
Variance, Standard Deviation, Range, Coefficient of variation, Z-scores, Confidence intervales, Relative standard deviation, Interquartile Range
Performance Outcome Measures
Focus on the end result, the outcome of performing a skill
Performance Process Measures
Focus on how movement was performed
Experimental Method: Mechanical
Joint/Segment motion, control of force, movement success, interactions between person and environment
Experimental Method: Electrical
Electromyography (EMG)
Experimental Method: Metabolic
Magnetic Resonance Imaging (MRI), fMRI, Position Emission Tomography (PET)
In-Phase Coordination
When two joints are flexing (or extending) at the same time)
Anti-Phase Coordination
When one joint is flexing and the other is extending
Pre-Motor Time
Amount of time between when the brain identifies a stimulus and when it organises a response
