PROBLEM TO BE SOLVED: To provide an exercise state measurement device capable of improving calculation accuracy of an exercise state.SOLUTION: An exercise state measurement device 1 has a measurement part 20 and a calculation part 10. The measurement part 20 is mounted on a person to be measured. The measurement part 20 has a light emitting part 21 for radiating near infrared rays, and a light receiving part 22 for receiving the near infrared rays passing in blood. The measurement part 20 outputs a signal according to the near infrared rays received by the light receiving part 22. The calculation part 10 calculates deoxygenated hemoglobin concentration based on the output of the measurement part 20, and calculates an exercise state by using the deoxygenated hemoglobin concentration and without using oxygenated hemoglobin concentration.COPYRIGHT: (C)2015,JPO&INPIT【課題】運動状態の演算精度を向上できる運動状態測定装置を提供する。【解決手段】運動状態測定装置1は、測定部20および演算部10を有する。測定部20は、被測定者に取り付けられる。測定部20は、近赤外光を照射する発光部21と、血中を通過した近赤外光を受光する受光部22とを有する。測定部20は、受光部22が受光した近赤外光に応じた信号を出力する。演算部10は、測定部20の出力に基づいて脱酸素化ヘモグロビン濃度を演算し、脱酸素化ヘモグロビン濃度を用い、かつ酸素化ヘモグロビン濃度は用いずに運動状態を演算する。【選択図】図2
