“…For the MinimaxX GPS, the Pearson values were between r = 0.722 and 0.969 [26,43], and limits of agreement values between -14.41 and 19.2 cm [26,43]. For the IMU devices that were tested only once for validity, the Pearson values were between r = 0.67 and 0.99 [31,33,37,40,48], and limits of agreement values between -15.6 and 19.2 cm [31-33, 42, 45, 46].…”

Inertial measurement units (IMUs) have been extensively used for measuring human motion. One particular outcome of interest in sports is vertical jump height, which is assessed in specific performance tests or actions occurring in training or match scenarios. This systematic review aimed to (1) identify and summarize studies that have examined the validity of wearable wireless IMUs for measuring jump height and (2) identify and summarize studies that have examined the reliability of wearable wireless IMUs for measuring jump height. A systematic review of the Cochrane Library, EBSCO, PubMed, SPORTDiscus, and Web of Science databases was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. From the 596 studies initially identified, 30 were fully reviewed, and their outcome measures were extracted and analysed. Among the 16 different IMU models, 15 were considered valid, with only one device not validated. Of the 7 IMUs that were tested for reliability, all were considered reliable for measuring jump height. In general, however, despite these findings, IMUs are not considered accurate enough to detect small changes in performance. Also, generalizations were not possible for athletic populations given the lack of studies with such samples.

“…Taken as a whole, the findings indicate that VJ height can be effectively calculated from accelerometer data only when the sensor is placed on the foot. The presented approach is an alternative to the frequently used positioning of the sensor on the back of the participant [12,14,21] in terms of simplifying the calculation of the JH as there is no need to calculate the orientation of the sensor unit to extract the vertical acceleration component during the movement of the trunk. In addition, the present study provides the data related to the VJ height estimate in elite athletes using the proposed sensor placement which is lacking in [26].…”

“…As different commercial and custom IMU-based systems have been validated in relation to the measurement of VJ height [19,20], different positioning of the sensor device on the athlete's body has been used. In studies by [12,14,21] sensors have been positioned on the lumbar area at the level of vertebrae L5, while a study by [17] used the positioning of the sensor on the athlete's ankles.…”

The aim of the present study was to determine if an inertial measurement unit placed on the metatarsal part of the foot can provide valid and reliable data for an accurate estimate of vertical jump height. Thirteen female volleyball players participated in the study. All players were members of the Republic of Serbia national team. Measurement of the vertical jump height was performed for the two exemplary jumping tasks, squat jump and counter-movement jump. Vertical jump height estimation was performed using the flight time method for both devices. The presented results support a high level of concurrent validity of an inertial measurement unit in relation to a force plate for estimating vertical jump height (CMJ t = 0.897, p = 379; ICC = 0.975; SQJ t = −0.564, p = 0.578; ICC = 0.921) as well as a high level of reliability (ICC > 0.872) for inertial measurement unit results. The proposed inertial measurement unit positioning may provide an accurate vertical jump height estimate for in-field measurement of jump height as an alternative to other devices. The principal advantages include the small size of the sensor unit and possible simultaneous monitoring of multiple athletes.

“…The researchers found the accelerometer system overestimated vertical jump heights by approximately 7 cm when compared to a laboratory-based force plate system (Heredia-Jimenez & Orantes-Gonzales, 2020). Moreover, agreements in vertical jump height measurements have been noted between accelerometers and various motion capture systems (Grainger et al, 2020;Mahmoud et al, 2015), but it is not known how these devices compare to force plate evaluation.…”

While force plate technology is the gold standard for assessment of many aspects of vertical jump performance, its cost is prohibitive to a broad spectrum of the population. Accelerometry may be more practical, inexpensive, and provide a simple solution that allows hands-on practitioners to readily assess vertical jump performance acutely and over time. Thus, the purpose of this study was to examine the accuracy of an experimental accelerometer for testing vertical jump heights derived from flight times when compared to a laboratory-based force plate system as a criterion measure. Fifteen subjects performed three sets of three nonconsecutive maximal countermovement vertical jumps while standing on the force plate. The accelerometer device sampling at 100 Hz was placed on the anterior abdomen immediately inferior to the umbilicus and secured with an elastic band. Both devices recorded the data simultaneously. The experimental accelerometer was an appropriate tool for the assessment of vertical jump height; however, it significantly overestimated actual vertical jump heights by an average of 3.1 cm. This consistent discrepancy in the measurement may be easily fixed by a simple algorithm correction and should not present an issue in the practical setting where ease of use and the ability to provide immediate feedback regarding an athlete’s performance is of critical importance.
