Hello,
Quite technical but good article on strength training and nervous system :
ARTICLES | Journal of Applied Physiology
The conclusion is :
(MVC = Maximal Voluntary Contraction)
"At the end of the training period, the strength training group displayed a significant improvement in both maximal isomeric and dynamic muscle strength. After 4 wk of strength training, the group average maximal dynamic strength increased significantly by 31.2% from 10.5 ± 2 to 13.8 ± 1.8 kg (
P < 0.001*). MVC also increased significantly by 12.5% from 21.9 ± 2.7 to 24.8 ± 2.3 N·m (
P = 0.045*). The maximal dynamic as well as isometric muscle strength of the skill learning group and the control group remained unaltered. Skill learning group mean 1 RM was 12.9 ± 1.7 before and 12.9 ± 1.9 kg after the training period, whereas MVC was 25.1 ± 2.5 before and 24.7 ± 2.6 N·m after training. 1 RM in the control group decreased slightly from 12.4 ± 1.6 to 12.2 ± 1.6 kg. MVC in the control group was 21.6 ± 2.5 N·m before training and 21.7 ± 2.2 N·m after the training. These results imply that the strength training paradigm caused significant improvements of the subjects' maximal muscle strength. Neither the skill learning paradigm nor the experimental procedures induced changes in the maximal strength of the subjects."
So it appears that a 4 days training a week, with realatively low daily volume, not going to failure, increase the nervous system potential to generate more muscle tension (strength).
