The purpose of this study was to evaluate the effectiveness of different defending techniques employed by International Netball players when marking a shot at goal. Data collection was conducted through a hand notation system which analysed pre-recorded videos of international matches. The system recorded several variables including; Defensive Playing Position, Attacking Playing Position, Body Position, Location of Defender, Foot Position, Arm Placement, Body Action and Outcome of Shot. Non-parametric statistical tests were applied to the data collected, enabling any significant findings to be revealed. Statistical tests included; Mann-Whitney U-Test, Kruskal-Wallis H-Test and Cross tabulation. Body Action and Location were identified as portraying significant differences (p<0.05) on the shot outcome. Further tests also confirmed that in particular instances these two variables combined also had a significant difference on shot outcome. The results highlighted that an effective defensive strategy when marking a shot involved the body action; jump. This was evident at all locations of the shooting circle. With regards to location of defender, defensive strategies were most successful when defenders were located in locations 1 and 3. Therefore defenders should endeavour to force shooters to attempt shots from the outer area of the shooting circle. Aspiring international netball players need to be aware of the most effective defensive strategies when marking a shot. This will enable them to acquire a greater understanding of possible technical strategies and achieve optimal performance.
