Adaptations in motor unit properties underlying changes in recruitment, rate coding, and maximum force
Jakob Lund Dideriksen, Alessandro Del Vecchio
Abstract
Our ability to measure adaptations in neuromuscular properties in vivo is limited. Using a computational model, we quantify the effect of multiple neuromuscular adaptations on common measures of motor unit recruitment, rate coding, and force-producing capacity. Scaling and combining adaptations had a near-linear effect on these measures, indicating that the results can explain and predict neuromuscular adaptations in a wide range of conditions, including, but not limited to, strength training.
