Abstract：
Previous research has demonstrated that professional mixed martial arts (MMA) athletes employ a variety of weight manipulation strategies to compete at given weight classes. Although there is much literature demonstrating weight manipulation methods, minimal research exists analyzing how much weight MMA athletes lose prior to the official weigh-in. Moreover, there is minimal research examining how much weight professional MMA athletes gain between the official weigh-in and competition. Therefore, the purpose of the current study was to analyze weight loss/regain in professional MMA athletes. Data collected from 616 professional MMA athletes (31.1 ± 4.0 yrs.; 177.1 ± 4.7 cm) competing for the Ultimate Fighting Championship (UFC) between 2020 and 2022 were used for the study. The athlete\'s weight was obtained 72 h, 48 h, and 24 h prior to the official weigh-in, at the official weigh-in, and prior to competition. Random effects analysis was utilized to compare weight at a variety of time points between different weight classes. All statistics were analyzed, and significance was set at p ≤ 0.05. There is a significant (p ≤ 0.05) difference between weight classes and time points in professional MMA. MMA athletes decrease body weight significantly prior to the official weigh-in. MMA athletes increase body weight significantly between official weigh-in and competition. Based on these data, it appears that MMA athletes average a weight loss of nearly 7% within 72 h prior to the official weigh-in. The data also suggest that athletes gain nearly 10% of total weight between the official weigh-in and competition.
摘要：
先前的研究表明，专业混合武术（MMA）运动员采用各种重量操纵策略来在给定的重量等级中竞争。尽管有很多文献证明了体重操纵方法，很少有研究分析MMA运动员在官方称重之前损失了多少重量。此外，很少有研究研究专业MMA运动员在官方称重和比赛之间获得多少体重。因此,本研究的目的是分析专业MMA运动员的体重减轻/恢复情况.从616名专业MMA运动员（31.1±4.0年。；这项研究使用了177.1±4.7厘米）在2020年至2022年之间争夺终极格斗锦标赛（UFC）。运动员的体重获得72小时，48h,在官方称重前24小时，在官方称重时，在竞争之前。利用随机效应分析来比较不同体重类别之间在各种时间点的体重。对所有统计数据进行了分析，显著性设定为p≤0.05。在专业MMA中，体重等级和时间点之间存在显着差异（p≤0.05）。在正式称重之前，MMA运动员的体重显着降低。MMA运动员在官方称重和比赛之间显着增加体重。基于这些数据,看来，MMA运动员在官方称重前72小时内平均体重减轻近7％。数据还表明，运动员在官方称重和比赛之间获得了近10％的总重量。
