Table 1.

Effect of voluntary (VOL) and electrically evoked (EVO) quadriceps contractions on peripheral and central fatigue

	VOL		EVO
	CTRL	FENT	CTRL	FENT
MVC (Δ%)	−15 ± 7	−12 ± 6	−33 ± 14*	−40 ± 14*
Q tw (Δ%)	−19 ± 10	−23 ± 11	−47 ± 21*	−59 ± 21*
VA (Δ%)	−2 ± 6#	1 ± 4#	1 ± 3#	0 ± 7#

Data are expressed as a percentage change from baseline. Majority of variables changed significantly from baseline after exercise. Note the similar exercise‐induced changes in neuromuscular function following CTRL and FENT within either exercise modality (P > 0.3). Pre‐exercise mean values for MVC, Q _tw, and VA were 224 ± 57 N m, 65 ± 18 N m, and 91 ± 6%, respectively. MVC, maximal isometric voluntary contraction; Q _tw, potentiated quadriceps twitch torque; VA, voluntary quadriceps activation. Data are presented as mean ± SD. ^#Not significantly different from pre‐exercise. ^* P < 0.05 vs. VOL.
