DTI‐based fiber tracking reveals a heterogeneous alteration of pennation angle upon muscle lengthening

The FASEB Journal, 2007
Introduction Diffusion tensor MRI (DTI)‐based fiber tracking can determine the 3D structure of muscle, including pennation angle (𝛉). The goal of this study was to determine how 𝛉 changes upon muscle lengthening. Methods

Mathematical model of pennate muscle. [PDF]

, 2015
The purpose of this study is to create a new mathematical model of pennate striated skeletal muscle. This new model describes behaviour of isolated flat pennate muscle in two dimensions (2D) by taking into account that rheological properties of muscle ...

Negative muscle pennation angle as a sign of massive musculotendinous retraction after tendon tear: paradoxical function of the vastus lateralis muscle [PDF]

, 2018
Case report In the presented case, an isolated vastus lateralis tendon tear resulted in a negative pennation angle of the distal muscle fibers acting paradoxical to the physiological direction of the proximal muscle fibers.

Musculoskeletal Proportionality, Biomechanical Considerations and Their Contribution to Movement in Adults and Children. [PDF]

The musculoskeletal system grows greatly throughout maturation. When trying to explain differences in strength, power and movement patterns between adults and children many pediatric exercise scientists will assume that this growth is proportional in all
