Motor unit systematic review project

The aim of this project was to identify and summarize all literature investigating motor unit discharge rate and discharge rate variability (coefficient of variation of the inter-spike interval; CoV-ISI) during voluntary isometric contractions at various force levels. Databases were searched up to May 9, 2024, and a total of 251 studies were included. The meta-means of motor unit discharge rate and CoV-ISI were estimated and compared across human muscles. As a secondary aim, we conducted linear meta-regressions to assess whether the effect of contraction intensity on motor unit discharge behaviour differed between muscles.For further details, please refers to the <b>READ ME</b> file.
