In the first step we build our own prototype to measure the radial acceleration. In the second step there is a validation with an infrared camera system. It is a comparison between the radial acceleration along the wire axis, that is measured by the sensor against the velocity that is delivered by the infrared camera system. As a result, significant correlation was observed between the measured velocity and the acceleration (r = 0.99, p &lt; 0.001). These suggest that this system can used in the training to improve the technique of the hammer throw.<\/jats:p>","DOI":"10.2478\/ijcss-2022-0001","type":"journal-article","created":{"date-parts":[[2022,3,24]],"date-time":"2022-03-24T19:54:48Z","timestamp":1648151688000},"page":"1-8","source":"Crossref","is-referenced-by-count":3,"title":["Wireless inertial sensor system for hammer throwing"],"prefix":"10.2478","volume":"21","author":[{"given":"Stefan","family":"Tiedemann","sequence":"first","affiliation":[{"name":"Dept.
