1986年至1990年对美国6个城市的活跃业余拳击手进行了研究，以确定两年间中枢神经系统功能的变化(通过知觉/运动功能、注意力/注意力、精神运动速度、记忆、视觉建构能力和精神控制、共济失调和脑干听觉诱发电位以及脑电检查来评估)是否与参与业余拳击的程度有关。共有484名参与者在基线时接受了检查；393人(81.2%)在两年后进行了检查。在基线时，22%的参与者还没有参加过一场比赛；9%的人在第二次考试时从未参加过一场比赛。暴露的定义是比赛次数、拳击年限和与职业拳击手的拳击次数。在暴露和功能改变之间几乎没有发现有统计学意义的优势比。在基线检查前发生的回合总数与记忆、视觉建构能力和知觉/运动能力的变化之间发现了显著的趋势测试。后两个领域的功能变化的显著趋势主要是由于区块设计测试的表现，这在两个测试域都是常见的。在最近的比赛(在基线访问之后)和任何功能领域之间，也没有发现在比赛或拳击和任何其他结果测量之间有统计学意义的关联。过去几场比赛的显著趋势，但不是最近的几场比赛，可能反映了在效果显现之前需要一个长潜伏期。或者，考虑到安全实践的变化，观察到的关联可能与1986年之前发生的更严重的接触有关，当时实施了新的安全措施。
Active amateur boxers from six US cities were studied in 1986–1990 to determine whether changes in central nervous system function over a 2-year interval (as evaluated by tests of perceptual/motor function, attention/concentration, psychomotor speed, memory, visuoconstructional ability, and mental control, measures of ataxia and brainstem auditory evoked potentials, and electroencephalography) were associated with degree of participation in amateur boxing. A total of 484 participants were examined at baseline; 393 (81.2%) were examined 2 years later. At baseline, 22% of the participants had not yet competed in a bout; 9% had never competed in a bout by the second examination. Exposure was defined by number of bouts, sparring-years, and sparring with a professional boxer. Very few statistically significant odds ratios were found between exposure and change in function. Significant tests of trend were found between the total number of bouts incurred before the baseline examination and changes in memory, visuoconstructional ability, and perceptual/motor ability. The significant trends for change in function in the latter two domains were primarily due to performance on the Block Design test, which was common to both test domains. No statistically significant associations were found between more recent bouts (after the baseline visit) and any functional domains, nor between bouts or sparring and any other outcome measures. The significant trends with past bouts, but not more recent bouts, may reflect the need for a long latency period before effects are manifest. Alternatively, given changes in safety practices, the observed association may be related to more severe exposure from bouts that occurred before 1986, when new safety measures were imposed.
