Abstract: Trunk motor control is essential for athletic performance, as the trunk is the centre of the kinetic chain and the base for limb movements. This thesis aims to expand the knowledge of trunk motor control in athletes compared to non-athletes, and whether it differs between athletes of different backgrounds, namely runners and golfers. Postural control was investigated using a seated postural control task. Neuromuscular control was investigated using sudden trunk loading perturbations. Proprioceptive ability was examined using active trunk repositioning. Athletes demonstrated greater trunk postural control during the seated postural control task compared to non-athletes. Athletes demonstrated faster trunk muscle activation onsets, higher muscle amplitudes, and less lumbar spine movement in response to sudden trunk loading perturbations when compared to non-athletes. Golfers demonstrated greater proprioceptive ability in trunk repositioning tasks compared to runners and non-athletes. This suggests an interactive relationship between neuromuscular control, postural control, and proprioception in athletes.
