This thesis explored field-based alternatives to 3D retro-reflective motion capture, with a focus on measurement of multi-planar trunk and pelvis motion. Cricket bowling was utilised as the primary reference movement task. An examination of 2D video digitising indi.cated it was unsuitable for comprehensive bowling analysis. Consequently, magneto-inertial measurement units were investigated. MIMUs produce valid 3D measurements of trunk and pelvis motion when their coordinate systems are closely matched with retro-reflective coordinate systems. However, substantial differences exist when MIMUs are assessed against gold-standard, 3D anatomically-based models. This has important implications for coaches and biomechanists considering field-based motion capture approaches.
