Contractile properties in control DIAm and following 42 days of SH-induced DIAm inactivity

	n	Pt, N/cm2	Po, N/cm2	Fatigue Index, %
Control	6	7.7 ± 1.1	19.7 ± 1.9	28.5 ± 1.1
SH	7	4.5 ± 2.1*	12.1 ± 4.0*	47.6 ± 23.8

Data were analyzed by 1-way ANOVA and are presented as means ± SD. P_t, peak twitch force; P_o, maximum tetanic force normalized for physiological cross-sectional area; Fatigue index is the ratio of force generated following repetitive stimulation (at 40 Hz in 330-ms trains each second) over 2 min to the initial force.

^*Significantly different from control (P ≤ 0.029).
