TECH BASED JUDGING

Hi Guys, The following article is an in-depth review of the best technologically-based, objective performance assessment methods currently under trial in elite-level snowboarding competitions

Abstract

This paper provides a review of objective performance assessment in elite half-pipe snowboarding.  Half-pipe snowboarding is currently coached and judged in competition using subjective measures.  Like other sports that rely on subjectivity however, the methodology underpinning how coaches assess athletic progression and judges score performance is open for debate.  This paper focuses on technology assisted, objective performance assessment.  Key considerations are the specificity of the information, the accuracy and reliability of results, the processing time required and the current accessibility.

BURTON OPEN ANALYSIS

Hi Guys, The following article is an objective and unique take on the level of snowboarding performance at the Burton Open Half-Pipe Championships held in Australia in 2008.

It is an objective take on a what is essentially a subjective lifestyle and will probably raise a few eyebrows from the discipline’s purists, however, I see no real harm in that. The analysis is heavily geared towards elite-level performance in what is now a highly regarded Winter Olympic discipline and is in line with sports-science methodologies. I also believe it contains the type of insight required to effectively manage the sport’s judging protocols in an age of continual technological progress.

The paper was recently published in the Journal of Performance Analysis in Sport and for anyone interested in elite-level half-pipe snowboarding performance (which I figure are riders, coaches, judges, officials, and spectators) it is more than likely, worth a read. A brief overview (abstract) of the paper is provided below. You can access the full paper from the link at the bottom of this post. Feel free to let me know if you have any trouble accessing the full paper.

Abstract

Half-pipe snowboarding performance is assessed by subjective measures. Knowledge of the relative importance of objective performance indicators however can improve training and competition performance assessment. We analysed previously developed key performance indicators at the Burton Open Australian Half-Pipe Championships over three years (2006, 2007, 2008). Linear regression showed the two individual key performance indicators most strongly correlated to competition success and multiple linear regression (enter method) showed the shared variance in scores explained by these objective variables. The two objective performance variables most highly correlated with competition success were average air time (AAT) and average degree of rotation (ADR). When combined (multiple linear regression), AAT and ADR objectively explain 71 – 94% of shared variance in subjective competition scores. We compared magnitudes of differences in AAT and ADR between athletes achieving top three (podium) final rankings and those achieving final rankings outside the top three. Magnitude of difference between athletic performances was established with a standardised (Cohen’s) effect size (ES) with 95% confidence limits. Differences in AAT and ADR between athletes placing in the top three and those finishing outside the top three routinely showed moderate (ES = 0.6 – 1.2 95% CL) to very large (ES >2.0 95% CL) effects.
