Description

<p>The purpose of this study was to evaluate the impact of boxing punches in a safe and non-invasive manner. We collected punching data from two experienced right-handed boxers. The motions were （1） jab, （2） one-two, （3） one-two-three and （4） one-two-hook. Thirty seconds of punching motions were collected in each case. The subject threw punches into punching mitts, which were held by an experienced boxer. Motion data were collected using an optical motion capture system. Ground reaction forces were collected in an experimental environment which has 15 force plates arrayed in a rectangle shape. Small and light-weight accelerometers were attached on the outside of the wrist of both arms. Based on the data from the motion capture system and force plates, the impulse of a punch was calculated as 10.00～19.87 kg･m/s and 7.28 N･s～9.85 N･s. The measured values from the accelerometers were found to exceed ±16G . The results of this research suggest that the impacts can be reasonably assessed in activities that include strong collisions such as boxing. These findings will be sound foundations to further develop this line of research.</p>
