Architectural Ultrasound Pennation Angle Measurement of Lumbar Multifidus Muscles: A Reliability Study [PDF]
Journal of Clinical Medicine, 2022 The pennation angle has been shown to be a relevant parameter of muscle architecture. This parameter has not previously been measured in the lumbar multifidus musculature, and it is for this reason that it has been considered of great interest to establish an assessment protocol to generate new lines of research in the future.

Dynamic measurement of pennation angle of gastrocnemius muscles during contractions based on ultrasound imaging [PDF]
BioMedical Engineering OnLine, 2012 Background Muscle fascicle pennation angle (PA) is an important parameter related to musculoskeletal functions, and ultrasound imaging has been widely used for measuring PA, but manually and frame by frame in most cases.

Changes in muscular pennation angle after crenotherapy. [PDF]
Muscles Ligaments Tendons J, 2013 Muscular architecture involves the organization of fibres in the muscle and is one of the most important factors of muscular function. Studies have demonstrated an association with muscular architecture and contraction, with an increase of the pennation angle in muscles.

Feasibility and Potential Effects of Exercise Training Combining Eccentric and Concentric Cycling in Patients With Breast Cancer. [PDF]
Eur J Sport SciABSTRACT Breast cancer treatment impairs aerobic and neuromuscular capacities, leading to a decrease in quality of life. Exercise may counteract these effects if it is individualized to patient characteristics. This study aimed to assess the feasibility and potential effects of combined concentric and eccentric cycling training on exercise capacity ...
