TA, tibialis anterior; Per brev, peroneus brevis; Sol, soleus; GM, gastrocnemius medialis; VL, vastus lateralis; ST, semitendinosus; Bi, biceps femoris. Frequency: frequency of occurrence, expressed as a ratio (i.e. the number of MUs in which a significant effect (P < 0.05 at least) was evoked/the number of units tested (raw values)), and, in parentheses, as a percentage (i.e. the former as a percentage of the latter). Size: mean values (±s.e.m.) of the size of the peak (Monosynaptic and Late excitation) or trough (Late inhibition), assessed as explained in Methods and expressed as a percentage of the number of triggers, calculated in all experiments with a significant effect. Latency and Duration: mean values (±s.e.m.) of the latency and duration of the effect, in milliseconds.
