Anterior cruciate ligament reconstruction (ACLR) may affect movement even years after surgery. The purpose of this study was to determine possible interlimb asymmetries due to ACLR when running on a treadmill and in field conditions, with the aim of contributing to the establishment of objective movement assessment in real-world settings; moreover, we aimed to gain knowledge on recovered ACLR as a biomechanical risk factor. Eight subjects with a history of unilateral ACLR 5.

Hence, the purpose of the current study was to investigate 'ride' and rollover with a heel cap-mounted inertial measurement unit (IMU) when running under field conditions to get realistic results. Twenty athletes ran on a 1 km outdoor track with five different shoe conditions, only differing in their midsole bending stiffness.

- Previous studies examined how different operating ranges (ORs) of accelerometers affect the accuracy of running measurements like stride length and running velocity, but their impact is still uncertain.
- The current study tested 21 recreational heel strike runners on a 15-meter track using various midsole stiffnesses in their footwear and combined different ORs when analyzing data from accelerometers placed on the runners.
- Results indicated that lower ORs led to significant underestimations of biomechanical parameters, suggesting that accelerometers should have at least a ±32 g OR for accurate measurements.
