The vastus lateralis neuromuscular activity during all-out cycling exercise.

Objective: The objective of this work was to study modifications in motor control through surface electromyographic (sEMG) activity during a very short all-out cycling exercise.

Methods: Twelve male cyclists (age 23+/-4 years) participated in this study. After a warm-up period, each subject performed three all-out cycling exercises of 6s separated by 2 min of complete rest.

Neuromuscular response of young boys versus men during sustained maximal contraction.

Purpose: This study was designed to compare neuromuscular response between boys and men during sustained maximal voluntary contraction (MVC).

Methods: Fifteen boys (YB, 10.5 +/- 0.
