Mechanical factors that impact sensitivity of mdx anterior crural muscles to ECC in vivo. a Eccentric torque as a ratio of maximal isometric torque, b eccentric torque loss, and c isometric torque as a percent of initial following 70 eccentric contractions at varying stimulation frequencies muscles using a 40° angle change at 2000°/s. Different from ^*0 Hz, ^#52 Hz, ^$71 Hz, and ^Ɛ93 Hz. d Eccentric torque as a ratio of maximal isometric torque using, e eccentric torque loss, and f isometric torque as a percent of initial following 70 eccentric contractions at varying degrees of angle change at 2000°/s and 150 Hz. Different from ^*0°, ^#5°, ^$10°, and ^Ɛ20°. g Eccentric torque as a ratio of maximal isometric torque, h eccentric torque loss, and i isometric torque as a percent of initial following 70 eccentric contractions at varying velocities and contraction durations a using a 40° angle change. Different from ^*125°/s. j Eccentric torque as a ratio of maximal isometric torque, k eccentric torque loss, and l isometric torque as a percent of initial following 70 eccentric contractions using a 10° angle change at varying velocities and contraction durations. Different from ^*62°/s, ^#125°/s, ^$250°/s, and ^Ɛ500°/s. Data are mean ± S.E.M with significance set at p < 0.05. N = 3–9/protocol
