Abstract: The device has a torque measuring means for measuring the torque produced by pedals and a rotational speed measuring means for measuring the pedal rotational speed. Pedal load is controlled such that it increases gradually. The correlation between the torque achieved by a subject and the pedal rotational speed is measured at two or more points until the subject can no longer resist the pedal load. These measurement data are approximated by a curve. The device has a control means for estimating the maximum torque achievable by the subject to be the torque achieved by the subject as the pedal rotational speed approaches zero based on this measurement data curve. Thus, the device enables adequate evaluation of myodynamia without achieving maximum myodynamia.

Abstract: A proanthocyanidin, such as an extract of grape seeds or skin, is added to a protein food, so that the flavor of the protein food is improved.
