Grinding is integral to tacking and gybing manoeuvres in Americaâs Cup sailing. Grinding is a standing position cyclic upper body task requiring manual arm cranking of winches, which control movement of the mast and sails. Limited information exists on biomechanical factors involved in grinding performance. This thesis determined technique and muscular performance characteristics of sailors related to grinding performance, and effects of a training intervention on grinding performance. Reliability of grinding ergometer performance testing was evaluated across direction, load and heel conditions.
