Key points
Previous studies have indicated that several weeks of strength training is sufficient to elicit significant adaptations in the neural drive sent to the muscles.
There are few data, however, on the changes elicited by strength training in the recruitment and rate coding of motor units during voluntary contractions. We show for the first time that the discharge characteristics of motor...
Introduction
Muscle activation was investigated during resistance exercise with 2 relatively high‐intensity loads.
Methods
Ten resistance‐trained men performed the leg press exercise to repetition failure: a set at 70% of 1‐repetition maximum (1RM) and a set at 90% of 1RM. Surface electromyography (EMG) was used to assess peak and mean muscle activation of the vastus lateralis, rectus femoris,...
