The present invention relates to a device for measuring an exercise amount which is installed on a body or an exercise equipment and measures amount of the exercise. The device for measuring an exercise amount comprises: a main body having a pair of through holes penetrated in both sides a fixing means including an insertion unit which is inserted and fixed to the through hole so that the body of a wearer or the exercises equipment can be mounted to one of the through hole of the main body, a hanger unit which covers a side of the main body and prevents the main body from being separated and a ring interposing a plurality of protrusion unit to prevent from being slipped from the body of the wearer or the exercises equipment a sensing means which contains a sensor for sensing a movement of the wearer or the exercises equipment within the main body, and converts information obtained from the sensor into a numerical value of the exercise amount and a terminal means which confirms the amount of exercise by the user using the numerical value of amount of exercise obtained from the sensing means. Thus, the wearer can measure the amount of the exercise with mounting the measuring device on the body or the exercise equipment, and check the own exercise amount through a desktop, a notebook PC, a smart-phone and a PDA, and so on, thereby confirming the own exercise amount and planning exercise design. Moreover, the device can be installed on the body of the wearer or the exercise equipment through the fixing means or to be installed on shoes while the fixing means is detached.COPYRIGHT KIPO 2016본 발명은 착용자의 신체 또는 운동기구 상에 장착하여 운동량을 측정하는 운동량 측정 장치에 있어서: 양측에 관통된 한쌍의 통공을 구비하는 본체 상기 본체의 통공 중 하나에 착용자의 신체 또는 운동기구에 장착되게 통공에 삽설되어 고정되는 삽입부와, 본체의 측면을 감싸 이탈을 방지하는 걸이부와, 착용자의 신체 또는 운동기구로부터 미끄러짐을 방지하는 다수의 돌기부를 개재하는 고리를 구비하는 고정수단 상기 본체 내부에 착용자 또는 운동기구의 움직임을 감지하는 센서를 수용하고, 센서로부터 얻은 정보를 운동량 수치로 변환하는 감지수단 및 상기 감지수단으로부터 얻은 운동량 수치 데이터를 사용자가 운동량을 확인할 수 있는 단말수단을 포함하여 이루어지는 것을 특징으로 한다.이에 따라 본 발명은, 착용자
