Brief summary
Accurate quantification and analysis of jumping and landing technique is one method to improve sport performance. The current gold-standard method for quantifying movement is three-dimensional biomechanical analysis in a motion analysis laboratory. However, due to financial, time, and logistical constraints, this method is frequently inaccessible to the wider sporting population. Wearable inertial measurement units (IMU) – consisting of micro-sensors– have been used as a cost-effective, accessible option that can provide real-time feedback of performance. To further promote wearable IMU use, it is important to evaluate the validity and reliability compared to the previously established method of motion analysis – three-dimensional biomechanical analysis. Study hypothesis: that wearable IMUs are a valid and reliable alternative to quantifying jumping and landing movements compared to three-dimensional biomechanical analysis.
Interventions
All participants will perform 3 athletic tasks - a) unanticipated 45 degrees change-of-direction manoeuvre, b) single-leg drop jump landing and c) bilateral drop landing. Their movements will be simultaneously assessed using a wearable inertial measurement unit (IMU) system (exposure), and a marker-based optical tracking system (comparator).
The exposure group - where movement will be assessed using wearable IMUs - will be performed using devices with in-built accelerometers, magnetometers, and
All participants will perform 3 athletic tasks - a) unanticipated 45 degrees change-of-direction manoeuvre, b) single-leg drop jump landing and c) bilateral drop landing. Their movements will be simultaneously assessed using a wearable inertial measurement unit (IMU) system (exposure), and a marker-based optical tracking system (comparator). The exposure group - where movement will be assessed using wearable IMUs - will be performed using devices with in-built accelerometers, magnetometers, and gyroscopes mounted on an elastic band to be snugly worn across the trunk (like a waist strap) and/or bodypart (like a thigh strap). The assessment will last a total of 90mins: Part 1 (15-30mins) - Participant brief, fitting wearable IMU system, and instrumenting retro-reflective markers on their body Part 2 (10-15mins x 3) - For performing each of the three tasks Part 3 (10-15mins) - Debrief participant and removal of instrumentation The entire process will be administered by an Australian Health Practitioner Regulation Agency registered Physiotherapist.
