Mixed martial arts (MMA) have become a fast-growing worldwide expansion of martial arts competition, requiring high level of skill, physical conditioning, and strategy, and involving a synthesis of combat while standing or on the ground. This study quantified the effort-pause ratio (EP), and classified effort segments of stand-up or groundwork development to identify the number of actions performed per round in MMA matches. 52 MMA athletes participated in the study (M age = 24 yr., SD = 5; average experience in MMA = 5 yr., SD = 3). A one-way analysis of variance with repeated measurements was conducted to compare the type of action across the rounds. A chi-squared test was applied across the percentages to compare proportions of different events. Only one significant difference (p < .05) was observed among rounds: time in groundwork of low intensity was longer in the second compared to the third round. When the interval between rounds was not considered, the EP ratio (between high-intensity effort to low-intensity effort plus pauses) was 1:2 to 1:4. This ratio is between ratios typical for judo, wrestling, karate, and taekwondo and reflects the combination of ground and standup techniques. Most of the matches ended in the third round, involving high-intensity actions, predominantly executed during groundwork combat.
混合武术（MMA）已成为全球范围内快速发展的武术竞赛项目，需要高水平的技能、身体素质和策略，并涉及站立或地面战斗的综合运用。本研究量化了努力-暂停比（EP），并对站立或地面技术发展的努力阶段进行分类，以确定 MMA 比赛中每轮的动作次数。52 名 MMA 运动员参与了这项研究（M 年龄=24 岁，SD=5；平均 MMA 经验=5 年，SD=3）。采用单向方差分析和重复测量来比较回合中动作的类型。卡方检验用于比较不同事件的比例。仅观察到回合之间的一个显著差异（p<.05）：低强度地面动作的时间在第二轮比第三轮更长。当不考虑回合之间的间隔时，EP 比（高强度努力与低强度努力加暂停之间的比）为 1:2 到 1:4。该比值介于柔道、摔跤、空手道和跆拳道的典型比值之间，反映了地面和站立技术的结合。大多数比赛在第三轮结束，涉及高强度动作，主要在地面战斗中执行。
