Objectives: The underlying mechanism of heart rate variability (HRV) of the
central nerves system is related with motor control. But, little is known for the association
between the HRV and fi ne motor performance. Method: The HRV of 32
healthy participants was measured using a short-term recorder, and spectrum analysis
was conducted for their fi ne motor performance using fi nger tapping test.
Results: The study fi ndings showed that the fi nger tapping test on the left hand
was signifi cantly related to the higher level of low frequency component (r = 0.36,
p < 0.05), and signifi cantly related to the lower level of higher frequency component
(r = -0.36, p < 0.05) of HRV. Conclusion: Elevated sympathetic tone could
be related with better fi ne motor response among health individuals.
