Much development work and scientific research has been conducted in recent years in the field of detecting human activity and the measurement of biomechanical performance parameters using portable sensor technologies, so-called wearable systems. Despite the fact that boxers participating in one of the most vigorous and complex disciplines of all sports, it is one of the disciplines where no noteworthy, advanced performance analytic tools are used for training or for competition purposes worldwide. This research aimed to develop and validate a comprehensive punch performance sensor system for the measurement and analysis of biomechanical parameters in the sport of boxing. A comprehensive validation study on linear regression was conducted following the development of the sensor system, between the gold standard of a Kistler force plate and Vicon motion capture system, to compare sensor-derived measurements with the gold standard-derived measurements. The developed sensor system demonstrated high accuracies ranging from R = 0.97 to R = 0.99 for punch force, acceleration, velocity and punch-time data. The validation experiments conducted demonstrated the significant accuracy of the sensor-derived measurements for predicting boxing-specific biomechanical movement parameters while punching in field use. Thus, this paper presents a unique sensor system for comprehensive measurements of biomechanical parameters using the developed mobile measurement system in the field of combat sports.
近年来，在使用便携式传感器技术（所谓的可穿戴系统）检测人体活动和测量生物力学性能参数方面开展了大量的开发工作和科学研究。尽管拳击手参与的是所有运动中最激烈和最复杂的运动项目之一，但在全球范围内，该运动项目并没有用于训练或比赛目的的先进表现分析工具。本研究旨在开发和验证一种用于拳击运动中生物力学参数测量和分析的综合拳击性能传感器系统。在传感器系统开发之后，对线性回归进行了全面的验证研究，将 Kistler 力板和 Vicon 运动捕捉系统的黄金标准与传感器衍生的测量值进行了比较。所开发的传感器系统在拳击力、加速度、速度和拳击时间数据方面的准确性很高，范围从 R = 0.97 到 R = 0.99。验证实验表明，在现场使用中，传感器衍生的测量值在预测拳击特定生物力学运动参数方面具有显著的准确性。因此，本文提出了一种独特的传感器系统，用于在格斗运动领域使用开发的移动测量系统进行综合生物力学参数测量。
