Abstract:
The purpose of this study was to develop a system for analyzing sports performance, determining performance indicators, and predicting competition results of male beach volleyball games by collecting information from video recordings of final sixteen teams participating beach volleyball competition during the 40th Thai National Games in Khon Kaen province, Thailand, a total of 38 matches, 176 sets, and 6,308 scores from 8,541 serving data, 6,196 serving reception data, 7,668 setting data, 9,580 attacking data, 5,988 digging data, 5,421 blocking data, and 6,231 scoring data. It was found that development of sports performance analysis to analyze winning and losing points during competition from serving, serving reception, attacking, setting, digging, and blocking in beach volley games can be performed well using Focus X2 software. From analysis, the average attacking was 23.70 times per set, average setting was 21.72 times per set, average serving was 17.78 times per set, average serving reception was 17.60 times per set, average blocking was 16.99 times per set and average digging was 15.39 times per set.It was found from performance analysis that key performance indicators were winning point from attack indicator 58.12%, losing point from blocking indicator 55.90%, attacking by spiking indicator 43.17%, winning point from attacking indicator 38.65%, float serve indicator 84.76%, easy to receive serving indicator 73.98%, excellent digging indicator 29.53%, excellent setting indicator 78.03%, and competition results using performance indicators derived from using Focus X2 software could be predicted with 92.86% accuracy from 26 out of 28 matches. The researcher has visual basic predictive values in each performance indicator to assess the best prediction using the average of all performance indicators compared to team averages for analysis and predictive analytics
