3. Psychomotor Efficiency Hypothesis
A refined orchestration of neuromotor processes in the brain
Minimized interference with the central motor processes for the neuromotor activity
Structured
Consistent

5. Sensorimotor Rhythm (SMR)
Activity in sensorimotor cortex
Higher
Lower
Superior Performance
(Sterman, 1996)
12-15 Hz

10. Results - Control Analysis
No changes was observed in the flanking frequency bands

11. Discussion The Superior Putting Performance Psychomotor Efficiency
Higher SMR power
Lower interference in the sensorimotor area
More automaticity
Psychomotor Efficiency
Specialized cortical activity
SMR as an indicator

12. Conclusion
The superior putting performance is typified by the lowered activation in the sensorimotor cortex
The activation of the sensorimotor cortex might serve as an indicator to investigate the psychomotor efficiency hypothesis
