Abstract: An exercise support apparatus includes an information processing unit that supports a setting of a next exercise menu for improvement to a targeted body, based on prior body motion information on a subject detected by a motion sensor. The information processing unit includes an image display processing unit that outputs distribution information on an amount of activity and a number of steps of at least one category obtained by classifying activity intensity that has been obtained from a target people group in advance, for each of the selected category, stored in a storage unit, and selected in advance, to a display unit, an activity amount processing unit that calculates the amount of activity and the number of steps for a same category as a selected category, based on body motion information on the subject, and that stores a calculation result in a measurement data storage unit, and an image display processing unit that outputs the amount of activity and the number of steps that have been calculated by the activity amount processing unit, to the display unit.

Abstract: To provide a collagen sponge excellent in mechanical strength and a production method for the collagen sponge. A collagen sponge including a porous construct having a pore structure, the collagen sponge having a tensile strength of 1 N or more and 5 N or less in every direction including a length direction and a width direction. The collagen sponge may be produced by a production method including the following steps: (1) a step of subjecting a collagen solution obtained by mixing collagen and a solvent to stirring and deaeration treatment; (2) a step of subjecting the collagen solution to freeze-dry treatment; and (3) a step of subjecting a dried collagen product after the freeze-dry treatment to insoluble treatment.

Abstract: Disclosed are a ground reaction force index estimation system, a ground reaction force index estimation method, and a ground reaction force index estimation program that can compute ground reaction force indices at low computation costs. The ground reaction force index estimation system comprises footwear and an external device connected to the footwear. The footwear comprises a wearable sensor that measures triaxial acceleration and/or triaxial angular velocity and a computation unit that computes ground reaction force indices by multiple regression analysis from values computed from the measurement results to be used as explanatory variables. The external device comprises a controller that evaluates walking and running motions for the user on the basis of the measurement results by the wearable sensor received from the footwear, the computed ground reaction force indices, and the determination reference information and a presentation unit that presents the results of the evaluation of the running motion.

Abstract: An apparatus (1) includes an exercise sensor (31) that continuously detects a movement of an exerciser accompanied by intermittent exercise, and a heart rate meter (32) that continuously measures a heart rate of the exerciser, and further includes an activity detection unit (12), a heart rate monitoring unit (13), an activity monitoring unit (14), and a notification processing unit (15). The activity detection unit (12) detects, from the movement of the exerciser, an activity intensity, a high activity intensity period, and a low activity intensity period. The heart rate monitoring unit (13) detects a declining trend in the heart rate of the exerciser, in the low activity intensity period each time, and monitors whether or not the declining trend of this time is low as compared with a predetermined reference. The activity monitoring unit (14), in a case in which the monitoring by the heart rate monitoring unit is affirmed, monitors whether or not the activity intensity to be detected in the high activity intensity period of a next time is low as compared with activity intensities detected in high activity intensity periods up to a previous time. The notification processing unit (15), in a case in which the monitoring by the activity monitoring unit is affirmed, forecasts an outbreak of disease. With this configuration, the outbreak of disease in an exerciser during an exercise is forecasted with higher accuracy.

Abstract: Provided is a collagen sponge which has compressive strength (stress) equivalent to that of a tissue into which the collagen sponge is to be implanted, has no unevenness in structure and stress, and has a pore structure for allowing cells to infiltrate thereinto. The collagen sponge is obtained by subjecting a collagen dispersion, a collagen solution, or a mixture thereof having a collagen concentration of 50 mg/ml or more to freeze-drying and insolubilization treatment thereafter. The collagen sponge thus obtained has a stress of from 10 kPa to 30 kPa when loaded with 10% strain, has in its surface and inside a pore structure having a mean pore diameter ranging from 50 μm to 400 μm, and has a pore diameter standard deviation equal to or less than 80% of the mean pore diameter.
