The impact of video review in sport karate (English)
Abstract [sv]

SyfteSyftet med denna studie var att, genom analys av inspelade matcher från en Premier League-tävling inom sportkarate, undersöka vilken effekt videogranskning har för matchens utgång.MetodUnder analysen av de inspelade matcherna noterades tidpunkten för begärd videogranskning och dess utfall samt aktuell poängställning. Vidare noterades matchkategori (kval/final), kön, viktklass, tävlingsfärg (röd/blå) och slutresultat i en mall. För att besvara de uppsatta frågeställningarna användes Χ2-test där analyserna genomfördes med hjälp av Statistical Package for Social Science (SPSS). Alfanivån för statistisk signifikans sattes till 0,05.ResultatAv samtliga 555 analyserade matcher var 9,7% av videogranskningarna matchavgörande. Totalt av samtliga begärda videogranskningar blev 30,7% av dessa beviljade. Fler videogranskningar görs samtidigt som färre videogranskningar beviljas desto längre matchen går (båda är p < 0,01). Det görs även fler videogranskningar i underläge jämfört i överläge (p < 0,001). Ingen signifikant skillnad beroende på matchkategorin och videogranskningens poängutfall hittades (>0,05). Ingen skillnad i beviljade videogranskningar fanns mellan utövarna (aka = röd/ao = blå).SlutsatserVideogranskning är ett effektivt verktyg för att ge en mer rättvis bedömning av internationella matcher inom sportkarate och kan ha en direkt påverkan på matchresultatet.

Abstract [en]

PurposeThe purpose of this study is, by analyzing recorded matches of a Premier League competition in sports karate, to investigate what effect video review has on the match outcome.MethodsDuring the analysis of the recorded matches, the time of the requested video review and its outcome and the current score was noted. Furthermore, match category (elimination/ final), gender, weight class, competition color (red / blue) and the matchresults were noted. To answer the questions of the study, Χ2-test were used by the Statistical Package for Social Science (SPSS) program. The alpha level for statistical significance was set to 0,05.ResultsOf all the 555 matches that was analyzed, 9,7% of the video reviews were critical for the match outcome. Total of all requested video reviews was 30,7% granted. More video reviews were done and fewer are granted the longer the match goes (both are p < 0,01). More video reviews are made in the underdogposition compared to the dominant position (p < 0,001). No significant difference was found depending on the match category and the video review outcome (> 0,05). There was no difference between the video review granted between the competitors (red/blue).ConclusionsVideo review is an effective tool to give a fairer judgement on international matches in sport karate and can have a direct impact on match outcome.
