Different sensors have been used widely in sports testing over the past years and practical solutions would be useful for coaching. The purpose of this study was to investigate the validity of an on-shoe 3D accelerometer sensor in jump height evaluation in athletes\u2019 own sport.\r\nAthletes from cycling, orienteering and basketball were studied to examine the suitability of the on-shoe 3D sensor method for different types of athletes. Subjects (n=29) performed three squat jump (SQJ) and three countermovement jump (CMJ) tests twice. Jump heights were assessed with a Stride Sensor Bluetooth\u00ae Smart (Polar Electro Oy, Kempele, Finland) attached on a shoe when jumping on a force plate (FP). A FP flight time method was used as reference for jump height and a FP take of velocity method was used for comparing the maximum jump results.\r\nThe paired correlation between the 3D sensor and the FP flight time method was 0.97-0.99 (p<0.001). Jump height for SQJ (n=174) with the sensor was 30.4 \u00b1 5.6 cm and with the FP method 29.1 \u00b1 5.2 cm. In CMJ (n=167) the corresponding values were 33.5 \u00b1 6.3 cm and 32.1 \u00b1 5.9 cm with the sensor and FP, respectively. Single measurements showed high consistency (p<0.001) also with SQJ ICC: 0.95, 95% CI: 0.50-0.98 and with CMJ ICC: 0.95, 95% CI: 0.51-0.98. The correlation of the maximum jumps between the 3D sensor and the FP take of velocity methods was 0.88 (p<0.001). The maximum jump heights with sensor method for the basketball players was 37.1 \u00b1 6.1 cm, which was significantly higher (p<0.001) than the orienteers 32.0 \u00b1 4.9 cm and mountain bikers 30.3 \u00b1 5.7 cm.\r\nThe 3D sensor and the FP methods correlated highly significantly in the evaluation of SQJ and CMJ height results of three different types of athletes. However, there was a small but systematic difference in jump height between the methods. The SQJ showed slightly better correlation and less variability with smaller bias of height results than CMJ. The correlation of the 3D sensor method was better with FP flight time than with take of velocity method. These results indicate that a 3D accelerometer sensor implemented on-shoe can be used for jump height evaluation and for maximum jump test. The 3D sensor method would likely offer a practical solution for jump height follow up in coaching.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Jarmo P\u00e4\u00e4kk\u00f6nen (jatapaak) on 2016-01-15 17:07:20.973264.
