The purpose of this dissertation was to evaluate the stability of strength asymmetry over a long-term period (1 year) and investigate the relationship of strength asymmetry to field test performance asymmetry in NCAA division-1 athletes. Isometric mid-thigh pull (IMTP) peak force asymmetry, ground contact time and finish time asymmetries on 10m sprint and 505 agility test performances were also observed. The impact of strength was also investigated in these studies to determine its effect on the magnitude of asymmetry. In the second study, peak force asymmetry over a one-year period was observed to be a rather volatile quality, with ranges between 16% or 8%, depending on the formula used. Based on this finding, it is possible that there may be a “normal” range of asymmetry that an individual athlete exhibits that could be linked to training adaptations along with other factors. Based on simple observation, an individual tendency toward symmetry existed in certain athletes. This relationship may be useful to explore in future study.
