Abstract
The muscle efficiency of a living animal is evaluated with apparatus comprising a nuclear magnetic resonance (NMR) analytical device that comprises a hollow electromagnet having a bore of sufficient size to receive the animal. A treadmill within the bore and beneath the animal is utilized to produce locomotion of the animal at different rates of work. The NMR analytical device is used to measure at different rates of work the following ratio within a locomotion-producing muscle mass of the animal: ##EQU1## where Pi is the concentration within the muscle mass of inorganic phosphate and PCr is the concentration within the muscle mass of phosphocreatine. Means is provided for relating the measured ##EQU2## values to the rates of work then being performed by the animal to provide an efficiency profile for the muscle mass.
