Leivseth, Gunnar Gruber, Markus Gruber, Markus 2011-12-27T15:09:00Z Helgerud, Jan 2011-12-27T15:09:00Z The purpose of this study was to investigate whether neural adaptations following functional multiplejoint leg press training can induce neural adaptations to the plantar Xexor muscles in a single-joint contraction task. Subjects were randomised to a maximal strength training (MST) (n = 10) or a control group (n = 9). MST consisted of 24 sessions (8 weeks) of 4 x 4 repetitions of horizontal leg press using maximal intended velocity in the concentric phase with the movement ending in a plantar Xexion. Neural adaptations in the soleus and gastrocnemius medialis (GM) were assessed by surface electromyographic activity and V-waves during maximum voluntary isometric contraction (MVIC), and also by H-reXexes in the soleus during rest and 20% MVIC. One repetition maximum leg press increased by 44 ± 14% (mean ± SD; P < 0.01). Plantar Xexion MVIC increased by 20 ± 14% (P < 0.01), accompanied by 13 ± 19% (P < 0.05) increase in soleus, but not GM surface electromyography. Soleus V/MSUP increased by 53 ± 66% and in GM by 59 ± 64% (P < 0.05). Normalised soleus H-reXexes remained unchanged by training. No changes occurred in the control group. These results suggest that leg press MST can induce neural adaptations in a single-joint plantar Xexion MVIC task. deposit-license eng Hoff, Jan Helgerud, Jan Functional maximal strength training induces neural transfer to single-joint tasks Leivseth, Gunnar Fimland, Marius S. 2009-09
