지난 40년 멀리뛰기선수의 경기력 추이 분석 = Analysis of Performance Trends of Long Jump Athletes over the Last 40 Years

다국어 초록 (Multilingual Abstract)

This study was conducted for the purpose of understanding the performance trends of long jumpers from 1985 to 2024. Using the Korea Association of Athletics Federations website, the annual best records of men and women in elementary, middle, high, college, and general divisions from 1985 to 2024 were collected.
The collected data were standardized into standard scores and visualized as line graphs to analyze the performance trends by growth stage, and the performance trends of long jumpers were analyzed by integrating the growth stages. The results of this study are as follows. First, the performance trends of long jumpers by growth stage show different aspects. The performance of elementary school athletes was the lowest at -1.95 in 2020, the highest at 2.15 in 1985, and a -0.04% decrease through linear regression. The performance of middle school athletes was the lowest at -1.35 in 2020, the highest at 1.95 in 1989, and a -0.02% decrease through linear regression. The performance of high school athletes was the lowest at -1.89 in 2020, the highest at 1.57 in 1991, and a -0.03% decrease through linear regression. The performance of college athletes was the lowest at -1.27 in 2020, the highest at 1.66 in 2005, and a -0.03% decrease through linear regression.
The performance of industrial athletes was the lowest at -2.10 in 1986, the highest at 1.81 in 2009, and a 0.05% increase through linear regression. Second, the performance trends of long jumpers vary. The performance trend starts in 1985 and declines until 1993, then rises until 2009, then declines slightly again until 2018, then declines sharply until 2021, and then rebounds until 2024, reaching the average record. In particular, the highest record is achieved in 1985 and the lowest record is achieved in 2020. Based on the standard deviation, the average record is maintained for a considerable period from 1988 to 2024, and the average record is above 1985, 1986, 1987, 2007, 2009, and 2014, and the average record is below 1993, 2019, 2020, 2021, and 2023. The performance trend of long jumpers is determined by the performance of the times, events, the efforts of the Athletics Association, and structural issues. It is hoped that the above research will help improve the performance of long jumpers in athletics as well as the performance of athletics athletes.
