  1. 1. ANALYSIS OF ATTACKS ON THE 25 YARD SECTOR IN FIELD HOCKEY Courtney McGowan email: u3028166@student.canberra.edu.au INTRODUCTION RESULTS CONCLUSION Field hockey has made only limited use of performance There was a total of 518 attacks on the 25 yard sector by the T3G From the analyses conducted, clear strategies on how to 60% analysis in the past. The majority of research has been teams and 603 attacks by the B3G. The majority of these attacks successfully attack the 25 y sector were developed. An confined to analysis of the types of shots on-goal used and occurred down the left-hand side for both groups ( T3G - 40.15%; important finding from this study was that the 25 y attacks 50% where those shots were taken in the 25 yard sector(1, 2, 3, 4). % O F E V E NTUAL O UTCO M E B3G - 48.09%; Figure 1). Passing was the most common method by the T3G were evenly distributed across the field The majority of attacks on the 25 y sector have been reported used by both groups to enter the 25 y sector ( T3G - 49.42%; compared to the B3G which tended to attack mostly down to occur from the right-hand side of the field (4), however 40% B3G- 58.0%; Figure 1). the left-hand side of the field.

Finally, they should encourage their team to ensure they Performance analysis was conducted on 15 elite men’s field There was a significant association between the number of attack down the left side as frequently as they attack down hockey games from the 2008 Men’s Champions Trophy.

The subjects were split into 2 groups T3G: Passes (χ2 (60) = 168.551, p = .000 < 0.001). The above findings were shown to lead to improvements in according to their overall placings in the tournament ( top 3 Time (χ2 (907) = 1274.927, p = .000 < 0.001). the likelihood of attaining positive outcomes in attacks on the ranked teams = Australia, Spain, Argentina [T3G]; bottom 25 y sector in this study.
