Thigh (A), quadriceps (B), and nonquadriceps (C) muscle volume in the immobilized leg corrected to the contralateral within-participant nonimmobilized leg at each time point. Muscle volumes were determined using MRI at day 0 and after 2 and 7 days of unilateral leg immobilization following either no exercise (CON; n = 11) or 300 eccentric muscle damaging knee extensor contractions performed in both legs immediately before immobilization (DAM; n = 10). Data are presented as means with lines representing individual responses. Statistical analysis was performed with separate two-factor ANOVAs. *Difference between time points. One symbol P < 0.05, two symbols P < 0.01, and three symbols P < 0.001.
