Key words: presynaptic inhibition of the Ia afferents of H-reflex stimulation.

When using all three delays between conditioning and testing stimuli, high-skilled sprinters have a significantly smaller increase in the amplitude of the H-reflex (p<0.05) than low-skilled sprinters. This fact indicates that presynaptic inhibition Of ia afferents coming from m. quadriceps to m. soleus motor neurons, more pronounced in highly qualified sprinters.
