  • Publication number: 20090182243
    Abstract: A body fat measuring apparatus includes: an upper limb unit including a hold portion that can be held in a hand of a subject and a main portion; and a lower limb electrode to be contacted with a lower limb of the subject. The hold portion includes an upper limb electrode, and the main portion includes a first surface to be contacted with a surface of an abdomen of the subject as well as a pair of first electrodes and a pair of second electrodes arranged at the first surface. The body fat measuring apparatus calculates a visceral fat amount of the subject based on two types of potential differences that are detected respectively in a case where an electric current is applied via a pair of the upper and lower limb electrodes and a case where an electric current is applied via the pair of second electrodes as well as physical data of the subject.

  • Patent number: 7366565
    Abstract: In an exercise machine, when a measurement starts, an electrocardiographic signal is detected by an electrocardiographic sensor 1 (ST33), a load drive is started (ST4), and heartbeat rate intervals of the electrocardiographic signal are sequentially obtained. A fluctuation of heartbeat rate intervals PI(n) % is obtained from a calculation formula in which the RR interval RR(n+1) of the current heartbeat is subtracted from the RR interval RR(n) of the previous heartbeat, which is then divided by RR(n) and multiplied by 100% (ST5). Entropy is calculated from 128 pieces of such PI (ST6). From the change of the entropy under the gradually increasing load (ST8), a minimum point of the entropy is obtained, which point is designated as an anaerobic threshold point (ST7). The load of the exercise machine is controlled employing this anaerobic threshold.

  • Patent number: 7326150
    Abstract: In the fat burning value calculating apparatus (6), an electrocardiographic signal is detected (1, 41, 45-47) at the start of exercise, and a heart rate is calculated from the detected value. Further, a power of heart rate variability is calculated, and an AT level is determined from the variability power. Once the AT level is determined, a preset exercise program is executed. A work load during the exercise is detected, and consumed calories are calculated. Thereafter, the electrocardiographic signal during the exercise is detected, the heart rate is calculated from the detected signal, and a fat burning rate during the exercise is calculated. A fat burning amount is calculated from the consumed calories and the fat burning rate, their accumulated values are also calculated, and these values are displayed.

  • Publication number: 20060224080
    Abstract: In a body fat measuring apparatus, a constant electric-current is flowed between hand electric-current electrodes and leg electric-current electrodes. From two detected voltages generated between an annular-shaped voltage electrode placed on an abdominal portion and two voltage electrodes placed at the both sides of a lumbar portion, two abdominal impedances are determined. Two electric-current electrodes and two voltage electrodes are placed such that they are spaced apart by a small interval from one another at an umbilicus portion. A constant electric current is flowed between the two electric-current electrodes and the impedance in the vicinity of the subcutaneous of the abdominal portion is determined from the detected voltage generated between the two voltage electrodes. From the two abdominal impedances, the impedance in the vicinity of the subcutaneous of the abdominal portion, and the input physique information, a viscera impedance is calculated.

  • Publication number: 20060206271
    Abstract: There are provided a hold portion that can be held in a hand of a subject, a cable having one end connected to the hold portion, and a rest portion on which a foot of the subject can be rested. The rest portion includes a reel portion connected to the other end of the cable for winding the cable, a first detection unit for detecting a draw-out extent to which the cable is drawn out from the reel portion, and a second detection unit for detecting an angle formed by the rest portion and the cable. Based on the detected draw-out extent and angle, the part length of a body part of the subject is calculated.

  • Patent number: 4927264
    Abstract: In order to measure the oxygen saturation in venous blood, a venous blood stream is made time-variant by applying pressure with a peak value of the minimum blood pressure to a proximal portion from a measuring part. Light beams with different wavelengths are transmitted from the measuring part and detected by photodiodes. Photodetected signals are logarithm-converted and venous signal components are separated from logarithm-converted signals with a filter circuit. The oxygen saturation of venous blood is calculated on the basis of separated venous signal components.
