An overhead view of a dissected rat muscle resting on grid paper.

The same view of the muscle as Image 1, but the muscle is translucent and grid lines are visible through it.

A fluorescence micrograph of the rat tibialis anterior muscle, stained to differentiate the long nerve fibers from the dot-like neuromuscular junctions.

A higher magnification of Image 3.

The innervation of the tibialis anterior muscle in a rat has never been so clear! Processed with SmartBatch+ by the UIC/Structural Circuits Core, for @greisinglab.bsky.social in the UMN School of Kinesiology. Red = nerves, yellow = neuromuscular junctions. #3DThursday @lifecanvastech.bsky.social

CORP: In Vivo Muscle Strength- Perspectives on the Design and Interpretation of Preclinical Animal Studies | American Journal of Physiology-Regulatory, Integrative and Comparative Physiology | American Physiological Society Accurate and reproducible tools to evaluate skeletal muscle contractility help to advance the field of physiology by defining skeletal muscle function in the context of skeletal muscle development, disease, aging, and injury recovery. The biomechanical assessment of muscle strength can be accomplished by measuring in vivo muscle torque, specifically, the muscle force generated at a moment arm around a joint. This approach to assess skeletal muscle contractility in preclinical animal studies primarily measures muscle torque in anesthetized animals using non-invasive electrophysiological stimulation. This method is advantageous because skeletal muscle contractions are evoked in a controlled, quantifiable manner that is independent of subject motivation allowing for maximal functional data and reproducible research outcomes. The purpose of this Cores of Reproducibility in Physiology (CORP) review is to discuss the underlying physiology of the in vivo method, to highlight common outcomes and their physiological importance, and to provide considerations for technical reproducibility and data interpretation. The hope is this CORP will provide skeletal muscle researchers with the foundational and practical knowledge to better incorporate the in vivo technique in their future studies.

Happy to contribute to this Cores of Reproducibility in Physiology with Drs. Call and Baumann
