Monitorointiin k\u00e4ytettiin Movesense-sensoreita, joilla voidaan mitata liikett\u00e4 kiihtyvyysanturin, gyroskoopin ja magnetometrin avulla. Tutkielmassa keskityttiin jalkakyykyn ja penkkipunnerruksen suorituksiin. Sensori kommunikoi matkapuhelimen kanssa BLE-protokollan avulla. Tutkielmassa k\u00e4ytettiin konstruktiivista tutkimusmetodia artefaktin eli prototyypin kehitt\u00e4miseen.

For the monitoring we used Movesense sensors, which were equipped with accelometer, gyroscope and magnetometer sensors. In this thesis we focused on squat and bench press movements. The used sensors communicated with a mobile phone with a wireless BLE-protocol. Design science research method was used in assistance with this thesis to perform a reliable study. According to the experiments performed in this thesis, we discovered that magnetometer and accelometer suits perfectly for the monitoring of a powerlifting movement, with an excellent accuracy and the ability to see any error in the trajectory of the movement. It was discovered that the optimal placement of the sensor in bench press was the ends of the bar. In squat the optimal placement was at the lower back of the performer. In this study we also explored the issue of data anonymity related to the information gathered. The majority of a identifiable data is possible to destroy with a simple filter to remove the actions before and after the movement. The BLE-protocol proved to be a worthy choice for the wireles communication.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2022-12-16T06:29:10Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2022-12-16T06:29:10Z (GMT).
