Abstract

This study investigated the association between judges’ scores and the varia­bles that represent judging criteria of surfing events. A total of 164 waves ridden by 21 international surfers were recorded and analyzed in two stages of the Brazilian ASP World Tour (2007 and 2010). The following tests were used for descriptive analysis of data: the Kolmogorov-Smirnov and the Student t test, one-way ANOVA, the Tukey post-hoc test and Pearson correlation analysis (p≤0.05). Significant differences were found between the scores of waves with bad, average and exceptional take-offs (p≤0.05) and with controlled exit, fall in the main section of the wave (MSW) and after the MSW (p≤0.001). There was a significant correlation (p≤0.05) between wave scores and the following variables: frequency of imbalance in the maneuvers (r=-0.30), percentage of maneuvers in the critical section of the wave (r=0.68), variety of maneuvers (r=0.62), frequency of carving (r=0.51), re-entry (r=0.43), floater (r=0.23) and cut-back (r=0.27) maneuvers, length of ride (r=0.76) and total frequency of maneuvers (r=0.79) for the ASP World Tour 2007; percentage of maneuvers in the critical section of the wave (r=0.34), variety of maneuvers (r=0.70), frequency of carving (r=0.46), re-entry (r=0.51), cut-back (r=0.30) and aerial maneuvers (r=0.30), length of ride (r=0.71) and total frequency of maneuvers (r=0.75) for the ASP World Tour 2010. The results showed that all surfing criteria used by judges in this study correlated significantly with scores in the ASP World Tour 2007 and 2010, except for frequency of imbalances in the second competition.

Highlights

  • Surfing is currently practiced in many countries, but it a more advanced competition sport in Australia, Brazil and the United States[1]

  • From sports that evaluate athlete performance according to objective measures, such as time, distance or height, esthetic sports rely on the subjective evaluation of a judging panel, which involves human judgment

  • This study evaluated the association between the scores assigned by judges and variables that are representative of judging criteria in surfing competitions according to the Association of Surfing Professionals (ASP) in international professional surfing competitions

Summary

INTRODUCTION

Surfing is currently practiced in many countries, but it a more advanced competition sport in Australia, Brazil and the United States[1]. The judgment of athlete performances has always been the greatest problem during competitions. The judgment criteria in most esthetic sports are limited, and few objective measurements justify the scores assigned by judges[2]. From sports that evaluate athlete performance according to objective measures, such as time, distance or height, esthetic sports rely on the subjective evaluation of a judging panel, which involves human judgment. Judgment criteria may be described in details, several factors may affect scoring[2]. Sports such as gymnastics, figure skating, diving and surfing, for example, in which performance has measureable aspects, are often the focus of studies to identify how to best judge them. This study evaluated the association between the scores assigned by judges and variables that are representative of judging criteria in surfing competitions according to the Association of Surfing Professionals (ASP) in international professional surfing competitions
