Innovative dynamometer enables precise measurement of muscle power output in skeletal muscle, suggesting enhanced MRI analysis capabilities.
Abstract 31P-Magnetic Resonance Spectroscopy is commonly used to study muscle energy metabolism, in vivo in healthy and diseased humans. Skeletal muscle is a unique tissue in that its metabolic rate can increase 30-fold, depending on power output. Thus, comprehensive characterization of the metabolic response in working skeletal muscle requires a powerful yet precise dynamometer for controlling muscle power output. The design of such a device must be compatible with the strong, static magnetic field and constrained dimensions inside of the bore of the magnet, and with the horizontal position of the human subject.
