Estimation of the force-velocity properties of individual muscles from measurement of the combined plantarflexor properties.

The force-velocity (-) properties of isolated muscles or muscle fibers have been well studied in humans and other animals. However, determining properties of individual muscles remains a challenge because muscles usually function within a synergistic group. Modeling has been used to estimate the properties of an individual muscle from the experimental measurement of the muscle group properties.

Tendons from kangaroo rats are exceptionally strong and tough.

Tendons must be able to withstand the forces generated by muscles and not fail. Accordingly, a previous comparative analysis across species has shown that tendon strength (i.e.

The Contributions of Individual Muscle-Tendon Units to the Plantarflexor Group Force-Length Properties.

The combined force-length (F-L) properties of a muscle group acting synergistically at a joint are determined by several aspects of the F-L properties of the individual musculotendon units. Namely, misalignment of the optimal lengths of the individual muscles will affect the group F-L properties. This misalignment, which we named [Formula: see text], arises from the properties of the muscles (i.

Analyzing the potential benefits of using a backpack with non-flexible straps.

Background: Conventional backpack straps are flexible. Due to this flexibility, backpacks freely move on the human back. In this study, a new design of backpacks with non-flexible straps is proposed.

Cylindrical agar gel with fluid flow subjected to an alternating magnetic field during hyperthermia.

Purpose: In magnetic fluid hyperthermia (MFH), nanoparticles are injected into diseased tissue and subjected to an alternating high frequency magnetic field. The process triggers sufficient heat to destroy the cancerous cells. One of the challenging problems during MFH is blood flow in tissue.
