      <content:encoded><![CDATA[Change of direction movement is common in sports and the ability to perform this complex movement efficiently is related to athlete's performance. Wearable devices have been used to evaluate aspects of change of direction movement, but so far there are no clear recommendations on specific metrics to be used.

The aims of this scoping review were to evaluate the reliability and validity of inertial measurement unit sensors to provide information on change of direction movement and to summarize the available evidence on inertial measurement units in analyzing change of direction movement in sports.

A systematic search was employed in MEDLINE (Ovid), CINAHL (EBSCO host), SPORTDiscus (EBSCO host), EMBASE and Cochrane Database of Systematic Reviews and Web of Science to identify eligible studies. A complementary grey literature search was employed to locate non-peer reviewed studies. The risk of bias of the studies evaluating validity and/or reliability was evaluated using the AXIS tool.

The initial search identified 15,165 studies. After duplicate removal and full-text screening 49 studies met the inclusion criteria, with 11 studies evaluating validity and/or reliability.

There are promising results on the validity and reliability, but the number of studies is still small and the quality of the studies is limited. Most of the studies were conducted with pre-planned movements and participants were usually adult males. Varying sensor locations limits the ability to generalize these findings. Inertial measurement units (IMU) can be used to detect change of direction (COD) movements and COD heading angles with acceptable validity, but IMU measured or derived kinetic or kinematic variables present inconsistency and over-estimation.

Studies can be improved with larger sample sizes and agreement on the metrics used and sensor placement. Future research should include more on-field studies.]]></content:encoded>

      <content:encoded><![CDATA[Background: Research on change of direction movement (COD) has focused on factors related to performance and injury prevention or rehabilitation. Wearable devices are used to evaluate accelerations and angles during COD movement, but so far there are no clear recommendations on specific metrics to be used. Objective: To evaluate the reliability and validity of inertial measurement unit (IMU) sensors to detect COD movement and aspects related to COD movement. To summarize the available evidence on how wearable IMUs are used to analyze COD movement in sports and exercise. Design Scoping review. A systematic search was employed in MEDLINE (Ovid), CINAHL (EBSCO host), SPORTDiscus (EBSCO host), EMBASE and Cochrane Database of Systematic Reviews. A grey literature search was employed to locate nonpeer reviewed studies. The risk of bias of the studies evaluating validity and/or reliability was evaluated using the AXIS tool. Setting: Sport and exercise. Participants: Studies on sports related COD movements measured with IMUs. Main Outcome Measurements: Methodological quality of included studies on validity and reliability. Results: After screening 11,376 articles 47 studies remained, with eleven studies evaluating validity and/or reliability. Most of the studies were conducted with preplanned movements in the laboratory setting and participants were usually adult males. Varying sensor locations limits the ability to generalize these findings. Conclusions: There are promising results on validity and reliability of analysis of COD movement with IMUs, but the number of studies is small and the quality of the studies is limited. Studies using IMUs to evaluate COD movement can be improved with larger sample sizes and agreement on the metrics used and sensor placement. Future research should include on-field studies, where movements are unplanned and factors like speed and how opponent players affect the movements are included in analyses. ]]></content:encoded>
