The role of motor learning in increases of muscular strength due to training is still \nunclear. The aim of this study is to investigate the effect of motor learning on the changes in\nmuscular force during strength training, detraining, and retraining on previously untrained \npeople.\nThe study was conducted as a part of a larger project, of which one of the experimental groups \nwere included in this study. Participants were previously untrained (n = 20, 18-40 y.). The study \nconsisted of a 10-week training period, 10 weeks of detraining, and 10 weeks of retraining. \nTraining was conducted 2 times a week and all training sessions were supervised. All sets and \nrepetitions were recorded. Measurements during the study were 1 repetition maximum 1RM \nbilateral dynamic leg press (JP), maximal unilateral isometric voluntary contraction of the knee \nextensors (IPO) and cross-sectional area of vastus lateralis (VLA). Measurements were done at \nthe beginning of training periods, at 5-week interval during training periods and at the end of \nthe training periods.\nLeg press 1RM, IPO, VLA and training load of the leg press (JPHA) all increased during both \ntraining periods (p < 0.05). During both training periods JPHA (+ 43 % and + 30 %) increased \nmore than JP (+ 22 % and +15 %) (p < 0.05) and JP improved more than IPO (+ 12 % and + 9 \n%) (p < 0.05). Proportional changes in VLA (+ 15 %) were greater than changes in IPO during \nretraining period (p < 0.05). Additionally, IPO regressed back to the pretraining levels during \ndetraining, whereas JP and JPHA remained elevated.\nThe differences in structural and functional adaptations and differences in their timescales \nprovide evidence for the role of motor learning in strength development. Especially changes \nduring detraining support motor learning and the relative stability of neural changes when \ncompared to structural changes in musculature. Motor learning should be considered when \ndesigning strength training plans especially for previously untrained people, because changes \nin muscle function didn\u2019t affect changes in muscle hypertrophy.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2023-09-01T05:46:19Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2023-09-01T05:46:19Z (GMT).
