The present review summarizes current evidence and unresolved issues regarding training-induced changes in the architecture of human skeletal muscles. As architectural parameters, we focused on the fascicle length and pennation angle, which are related to force-generating capability of pennate muscles. Cross-sectional studies in sport athletes suggested changes in both the parameters following chronic sport-specific activities. Longitudinal training intervention experiments indicated direct evidence of the plasticity of the two parameters induced by resistance training, but no consensus has been reached regarding the factors influencing those changes. Considering the importance of fascicle arrangement on muscle function, future studies are required to explain the underpinning mechanisms of the adaptation.
