The mechanical properties of a boxing punch have been determined using several techniques. The results are consistent with the medical consequences of boxing discussed in the report of the Board of Science and Education Working Party on boxing. Data were gathered from a world ranked British professional heavyweight, Frank Bruno, as he punched an instrumented, padded target mass suspended as a ballistic pendulum. Within 0.1 s of the start the punch had travelled 0.49 m and attained a velocity on impact of 8.9 m/s. The peak force on impact of 4096N (0.4 ton), attained within 14 ms of contact, represents a blow to the human head of up to 6320N (0.63 ton). The transmitted impulse generated an acceleration of 520 m/s2 (53 g) in the target head. For comparison an equivalent blow would be delivered by a padded wooden mallet with a mass of 6 kg (13 lbs) if swung at 20 mph.
已使用多种技术测定了拳击一拳的力学性能。这些结果与科学与教育委员会拳击问题工作小组报告中所讨论的拳击对医学方面的影响相一致。数据是从世界排名靠前的英国职业重量级拳击手弗兰克·布鲁诺身上收集的，当时他击打一个作为弹道摆悬挂着的、装有仪器的、带衬垫的目标物。在开始后的0.1秒内，这一拳移动了0.49米，撞击时的速度达到8.9米/秒。接触后14毫秒内达到的4096牛（0.4吨）的撞击峰值力，相当于对人的头部高达6320牛（0.63吨）的一击。传递的冲量在目标头部产生了520米/秒²（53克）的加速度。作为比较，如果一个质量为6千克（13磅）的带衬垫木槌以每小时20英里的速度挥动，会产生等效的一击。
