	Subject A	Subject B
	(male)	(female)
Absolute baseline twitch (N)	3.8	7.6
% change	1.6	5.5
Absolute 3 min post twitch (N)	1.9	7.1
% change	1.1	4.9
Absolute ${\dot{V}}_{{\mathrm{O}}_2}$ (l min−1)	0.05	0.09
% change	1.0	2.6
Absolute ${\dot{V}}_{{\mathrm{O}}_2}$ (ml kg−1 min−1)	0.7	0.1
% change	1.3	0.2
Absolute ${\dot{V}}_{\mathrm{E}}$ (l min−1)	1	6
