Development of a boxing dynamometer and its punch force discrimination efficacy

Area of Science:

• Sports Science
• Biomechanics
• Performance Analysis

Background:

• Previous punch-measuring devices lacked ecological validity due to design limitations.
• Accurate measurement of multidirectional force components in punches is crucial for performance analysis.

Purpose of the Study:

• To develop and validate a sport-specific boxing dynamometer.
• To assess the device's ability to discriminate between different levels of boxing skill.

Main Methods:

• A triaxial force measurement system was integrated with a boxing manikin interface.
• Repeatability and accuracy were tested using simulated straight punches.
• Maximal punching force was compared across elite, intermediate, and novice boxers.

Main Results:

• The boxing dynamometer demonstrated effective discrimination between skill levels (elite, intermediate, novice).
• Maximal punching forces were significantly higher for elite boxers compared to intermediate and novice boxers.
• Rear hand punches generated greater maximal force than lead hand punches across all skill levels.

Conclusions:

• The developed boxing dynamometer offers improved ecological validity for analyzing athlete performance.
• The device can effectively differentiate punching force capabilities across various skill levels.
• Findings provide valuable data for targeted training and performance enhancement in boxing.
