TABLE 5.

Effects of age (mature/juvenile) and treatment (control/unloaded) on fatigue (% decline), during a 5 min train of indirect (nerve) or direct (muscle) stimulation.

	Indirect stimulation * † ‡	Direct stimulation* † ‡
Juvenile, CTL	67.1 ± 4.4	42.2 ± 3.0
Juvenile, UL	15.3 ± 10.2#	41.6 ± 7.7
Mature, CTL	82.7 ± 7.2	52.7 ± 5.7
Mature, UL	84.8 ± 3.7	58.1 ± 7.2

Values are mean ± SE, N = 10/group. Fatigue calculated as percent decline in peak tension during 5 min train of stimulation.

*Indicates significant (P ≤ 0.05) main effect for age (Mature > Juvenile).

^†Indicates significant (P ≤ 0.05) main effect for treatment (CTL > UL).

^‡Indicates significant (P ≤ 0.05) interactive effect between age and treatment, whereby Juvenile, HS is less than all other groups during that interval.

^#Indicates significant (P ≤ 0.05) difference from all other groups.

CTL, control; UL, unloaded.
