TABLE 4.

Effects of age (mature/juvenile) and treatment (control/unloaded) on time to peak tension (seconds) at beginning (Initial) and conclusion (Final) of 5 min train of indirect (nerve) or direct (muscle) stimulation.

	Initial		Final
	Indirect stimulation†	Direct stimulation	Indirect stimulation	Direct stimulation
Juvenile, CTL	0.845 ± 0.035	0.916 ± 0.093	0.835 ± 0.030	0.877 ± 0.022
Juvenile, UL	0.645 ± 0.111	1.004 ± 0.068	0.855 ± 0.060	0.955 ± 0.040
Mature, CTL	0.748 ± 0.038	0.837 ± 0.080	0.919 ± 0.030	0.976 ± 0.030
Mature, UL	0.613 ± 0.090	0.810 ± 0.054	0.911 ± 0.042	0.869 ± 0.087

Values are mean ± SE, N = 10/group.

^†Indicates significant (P ≤ 0.05) main effect for treatment (CTL > UL), i.e., longer time to peak force.

CTL, control; UL, unloaded.
