Purpose The purpose of this study is conducted to analyze the objectivity of the ski technical championships hosted by Korea Ski Instructor Association (KSIA) and to identify the error sources that affect the score of the competition. Methods To this end, we used the data from the 25th(2009) to 33rd(2017) ski technical championships held by the Korea Ski Instructor Association (KSIA). The data provided by Win Excel 2010 was used to sort out the missing data, such as abandonment, according to the data processing method. The collected data were analyzed by using SPSS 22.0 to calculate the mean and standard deviation of each season, event, and judges, and the Intraclass Correlation Coefficient (ICC). In addition, by using the single facet crossed design(p*j) of the generalizability theory’s G study, the variance component estimates for the participant(p) and the judges (j) are calculated, and the influence (%). Results As a result of the research, it was confirmed that the results of all the seasons and events from the 25th to the 33th events were very consistent, with the objective of .845~.986 higher than the recognition level of .80. In addition, the results show that the relative ratio of the judges to the error of the judging score is very low as a result of the error analysis through the dispersion component estimates. Conclusion In summary, the results of the KSIA evaluation are highly evaluated objectivity and have very low impact on the judges' errors.
PURPOSE This study aimed to develop physique and basic physical fitness evaluation criteria for middle school soccer players, providing a foundation for training and player development to be used by coaches in the field. METHODS The study involved 440 middle school soccer players (Grade 1=178, Grade 2=132, and Grade 3=130). Measurements were conducted on seven physique and ten basic physical fitness factors. Measurement results were organized using Windows Excel 2021 and descriptive statistics were performed using Windows SPSS 26.0. Based on the descriptive statistics of the measurement results, the Cajori 5-Grade evaluation method was applied to establish evaluation criteria for each grade and fitness component. RESULTS The study results provide evaluation criteria for middle school soccer players based on the measured data, considering grade, physique, and basic physical fitness. CONCLUSIONS The criteria established in this study are expected to be widely utilized by coaches in the field to set training goals for areas such as player selection, development, injury prevention, and rehabilitation.
