Thesis (M.Tech.: Chiropractic)-Dept. of Chiropractic, Durban University of Technology, 2007 xi, 60 leaves, Annexures 1-9 / The Transversus Abdominis (TrA) muscle is recognised in the literature as playing a vital and protective role in maintaining a healthy core and aiding lumbar biomechanics in the dampening of external forces applied to the lumbar spine. Pilates purports to employ the principles of core training yet there remains a deficit in the literature despite its popularity in rehabilitation and fitness industries. This study aimed to evaluate the efficacy of Pilates method in training the TrA in comparison to a moderately active population that regularly exercises in a gym environment, as well as a sedentary control.
