PROBLEM TO BE SOLVED: To provide a joint torque computing system, a cycle computer and a joint torque measuring method materializing downsizing and measuring a joint torque of lower extremities in a short time.SOLUTION: A joint torque computing system 10 includes a first detection part 11, a second detection part 12, and an arithmetic processing part 14. The arithmetic processing part 14 calculates second joint position information of a knee joint on the basis of rotation position information of a crank 31 acquired from the first detection part 11, length information from a hip joint to the knee joint, length information from the knee joint to an ankle joint, length information from the ankle joint to a pedal shaft 32, first joint position information of the ankle joint, and third joint position information of the hip joint. The arithmetic processing part 14 performs arithmetic processing by inverse dynamics analysis on the basis of tread force information applied to a pedal 33, acquired from the second detection part 12, and one information out of the first, second, and third joint position information, and calculates a joint torque of one joint out of the ankle, knee, and hip joints.SELECTED DRAWING: Figure 1

    【課題】小型化を実現し、短時間において下肢の関節トルクを測定する関節トルク演算システム、サイクルコンピュータ及び関節トルクの測定方法を提供する。【解決手段】関節トルク演算システム10は、第1検出部11と、第2検出部12と、演算処理部14とを備えている。演算処理部14は、第1検出部11から取得されるクランク31の回転位置情報と、股関節から膝関節までの長さ情報、膝関節から足首関節までの長さ情報及び足首関節からペダルシャフト32までの長さ情報と、足首関節の第1関節位置情報と、股関節の第3関節位置情報とに基づいて、膝関節の第2関節位置情報を算出する。演算処理部14は、更に第2検出部12から取得されるペダル33に作用する踏力情報と、第1、第2及び第3関節位置情報の1つの情報とに基づいて、逆動力学解析による演算処理を行い、足首、膝及び股の1つの関節の関節トルクを算出する。【選択図】図1
