Electronic Distance Measuring Instruments01:30

Electronic Distance Measuring Instruments

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short distances...

Area of Science:

  • Sports Science
  • Biomechanics
  • Martial Arts Performance Analysis

Background:

  • Accurate evaluation of combat sports techniques, like the roundhouse kick, is vital for athlete performance.
  • Traditional kick evaluation methods are often complex and expensive, limiting their practical application.

Purpose of the Study:

  • To introduce and validate a novel, accessible contact mat-based tool for measuring roundhouse kick execution time.
  • To assess the reliability of this tool in measuring attack and recovery phases of the kick.

Main Methods:

  • 16 male Shotokan karate athletes participated in a test-retest reliability study.
  • A standardized warm-up and roundhouse kick test protocol were used across four sessions.
  • Intraclass correlation coefficients (ICC) and Friedman tests were employed for statistical analysis.

Main Results:

  • The contact mat tool demonstrated high reliability for measuring attack (ICC=0.85), recovery (ICC=0.89), and total kick time (ICC=0.90).
  • No significant differences were found between the testing sessions (p > 0.31), confirming consistent measurements.
  • The tool proved to be a simple and reliable system for timing roundhouse kicks.

Conclusions:

  • The developed contact mat system offers a practical and reliable solution for assessing roundhouse kick timing in combat sports.
  • This tool can aid coaches and athletes in optimizing technique and performance through objective data.
  • Its accessibility and ease of use make it a valuable addition to sports performance analysis tools.
