Maximal knee extension torques were recorded at a specific joint angle (0.52 rad below the horizontal plane) for all test speeds. Subjects were randomly assigned to one of three experimental groups: group A, control, n = 7; group B, training at 1.68 rad . s-1, n = 5; or group C, training at 4.19 rad . s-1, n = 5. Subjects trained the knee extensors by performing two sets of 10 single maximal voluntary efforts three times a week for 4 wk. Before training, each training group exhibited a leveling-off of muscular tension in the slow velocity-high force region of the in vivo force-velocity relationship. Training at 1.68 rad . s-1 resulted in significant (P less than 0.05) improvements at all velocities except for 5.03 rad . s-1 and markedly affected the leveling-off in the slow velocity-high force region. Training at 4.19 rad . s-1 did not affect the leveling-off phenomenon but brought about significant improvements (P less than 0.05) at velocities of 2.51, 3.35, and 4.19 rad . s-1. The changes seen in the leveling-off phenomenon suggest that training at 1.68 rad . s-1 might have brought about an enhancement of motoneuron activation. <\/jats:p>","DOI":"10.1152\/jappl.1981.51.3.750","type":"journal-article","created":{"date-parts":[[2017,12,25]],"date-time":"2017-12-25T07:35:28Z","timestamp":1514187328000},"page":"750-754","source":"Crossref","is-referenced-by-count":156,"title":["Training-induced alterations of the in vivo force-velocity relationship of human muscle"],"prefix":"10.1152","volume":"51","author":[{"given":"V.
