    (A) The experimental setup for assessing voluntary wrist flexion strength and central activation. (B) Force trace of a maximal voluntary contraction coupled with superimposed electric stimulation to assess central activation. (C) No sex differences were observed at baseline for central activation, nor were immobilization-induced sex-specific effects observed. (D) Temporal changes in voluntary wrist flexion strength by sex during 3 weeks of immobilization and after 1 week of recovery.

    *Indicates significantly less than baseline when data are pooled across sex (P≤.05).

    †The recovery of voluntary muscle strength was depressed in women when compared with men (P=.03, η2=.46).
