Brief Summary

We will explored the effect of cross education training on different cortex functional connectivity, cortex and muscle functional connectivity, and maximal voluntary contraction. Healthy participants receive cross education training of the elbow flexor (12 rep./set, 3sets, 60%MVC, 180°/s, eccentric).Maximal voluntary contraction, electroencephalogram and electromyogram will record during cross education tasks to determine the effects of cross education training on cortical network and muscle functional connectivity

Conditions

Healthy Adults

Keywords

cross education, functional connectivity

Outcome Measures

Primary Outcomes (3)

• Corticocortical coherence

  Level of electroencephalography and electromyography synchronization in frequency domain when participants maintain 20% maximal voluntary contraction

  Measured immediately after cross education training

• Corticomuscular coherence

  Level of electroencephalography and electromyography synchronization in frequency domain when participants maintain 20% maximal voluntary contraction

  Measured immediately after cross education training

• Maximal voluntary contraction

  The ability to generate maximal voluntary elbow flexor force

  Measured immediately after cross education training
