| Summary: | Background and objective: This study investigates the physical factors
that determine the top ranker players based on the Greco-Roman wrestlers in the
national athletic team of South Korea. Additionally, the study developed a
prediction model using physical factors. For this analysis, the data of 163
players in the last 20 years (1999–2018) available on the Athletic Competition
Performance Assessment Computer System were used. A top ranker was defined as an
athlete who had won a medal in a world championship or the Olympic Games.
Methods: The logit model was used as the model and the estimations were
performed using maximum likelihood estimation (MLE) with E-views9.5 (Lightstone Corp., Tokyo, Japan). The estimation results demonstrated that the probability of becoming a top ranker
increased with the following: increase in the length of the career compared to
age, increase in the distance of standing long jumps, decrease in response time
to light, and increase in bench press weight.
Results: The analysis of the model’s estimation results showed that
superior results were produced when the standing long jumps, response time to
light, and bench press weight were normalized using the weight class based on
McFadden R2, Akaike Information Criterion (AIC), and Schwarz information
criterion (SBIC) as compared to when they were normalized using the height and
body weight.
Conclusion: The estimation model established in this study for the
significant physical strength factors shown in the South Korean top rankers is
expected to be used as important data for predicting and fostering world-class
South Korean Greco-Roman wrestlers.
