Abstract

The purpose of this study was to investigate the relative weights of physical strength factors in sports events. We selected 16,645 people as a sample group who participated in physical fitness measurements through eight sports science centers across the country from 2016 until August of 2018, and divided into four sports types depending on the sports physiological view: type A: short-term muscular power and short-term muscular endurance, type B: mid-term muscular power, type C: long-term cardiorespiratory endurance, type D: coordination capability (CC), agility, flexibility, and balance. Categorized the performance level into excellent athletes and non-excellent athletes, and standardized (T-score) the measured value after considering sex, age and sports type group. Used logistic regression analysis for the method of analysis, and calculated the relative weights of physical strength factor with different sports by using Wald value which was calculated from logistic regression analysis. As a result, the relative weights of physical factor in type A were power 30%, muscular power (MP) 18%, CC 16%, agility 11%, flexibility 10%, cardiorespiratory endurance (CE) 1%, and balance 0%. The relative weights of physical factor in type B were muscular endurance (ME) 43%, MP 25%, power 20%, balance 9%, CE 2%, flexibility 1%, agility 0%, and CC 0%. The relative weights of physical factor in type C were ME 41%, CE 37%, power 10%, agility 8%, flexibility 2%, CC 2%, ME 0%, and balance 0%. Need more specific classification standard for type D sports. Hope the results of this study were used to measure physical fitness level and used as baseline data for recruiting future talents.

Highlights

It’s a proven fact through many studies that physical strength is a vital factor to improve performance in sports
If one examines the studies about finding out the physical factors that are related with the performance, you can see that they are sorted by two big categories which are theoretical studies about the literature, or content validity with collections of expert opinions [1] and studies based on measurement of physical fitness data [2,3]
R2 generally appeared low in all sport type groups, but in case of logistic regression analysis, the sums of the coefficient of determinations differ depending on the value of a dependent variable, but still that value is generally low as well

Summary

Introduction

It’s a proven fact through many studies that physical strength is a vital factor to improve performance in sports. If one examines the studies about finding out the physical factors that are related with the performance, you can see that they are sorted by two big categories which are theoretical studies about the literature, or content validity with collections of expert opinions [1] and studies based on measurement of physical fitness data [2,3]. The first category has strength in internal validity and contents as it applies literature and the opinions of experts, while the other category has strength in objectivity as it applies physical fitness data. Both methods can verify the priorities of important physical factors of each sport, Appl.
