Participation of the ankle extensor muscle, LG, during RLMs in control posture and extension restraint. Participation of the ankle extensor muscle, LG, during RLMs in control posture and extension restraint. Participation of LG activity was quantified by the ratio of total LG burst number relative to total TA burst number in the same condition. LG participation is plotted for each experiment per age group: (A) E20, N=10; (B) E18, N=11; and (C) E15, N=9. The reduction in LG participation during extension restraint was significant (asterisk) at E20 (P<0.02) and fell just short of significant at E18 (P<0.055); at E15 it was not significant (P<0.3) (see Results for details).
