Summary of the mean changes in electrically induced contraction expressed as percent MVIC and corresponding mean changes of phase charge measured in microcoulombs (µC) recorded at the end of session one and six. Data are means (±SD)

		Session 1	Session 6	% Change
Females	%MVIC	21.3 (24.8)	44.6 (26.6)	109.4
	Charge(µC)	11.2 (6.2)	16.9 (8.0)	50.8
Males	%MVIC	60.7 (31.9)	74.1 (18.2)	22.0
	Charge(µC)	21.4 (8.5)	31.5 (8.6)	47.2

As seen, inter-subject variability was considerable in the studied sample. Note: The reported values would probably be different particularly in session 6 if the stimulator was more powerful (i.e., had higher maximal phase charge)
