The principal aim of the present thesis was to investigate the effect of increasing muscular strength on the co-ordination of movement during accelerative sprinting. Physically active males fro the University of Edinburgh participated in an 8-week resistance training study. Pre and post-training measures of 10 m and 20 m sprint time, maximum strength and explosive strength were taken. The first 3 strides of the 20 m sprint were videoed for further analysis. Changes in co-ordination were assessed using phase-plane diagrams and continuous relative phase (CRP) measures. The resistance training intervention resulted in a significant increase in maximum and explosive strength immediately following the training period, but sprint times were not improved. Increases in the vertical impulse, with concomitant decreases in the horizontal impulse were recorded following the training period. These changes caused a reduction in stride frequency. Although the resistance training increased muscular strength the control of the orientation of the ground reaction force with respect to the centre of mass (CoM), which has been identified as a specific constraint associated with the stance period of accelerative sprinting, was not adapted. The result of the present thesis demonstrates that an 8-week resistance training intervention increases muscular strength but does not improve accelerative sprint performance immediately following the training period. Sprint running performance is affected by the complex interaction of constraints associated with the task and the physical characteristics of the performer. Muscular strength has been identified as a characteristic that constrains the co-ordination of multi-joint movements. Considering the effect of resistance training on the control and co-ordination of multi-joint movements provides further insight into the effectiveness of potential training interventions, such as resistance training, and provides information for coaches to develop strategies to expedite the transfer of strength to accelerative sprinting.
