To systematically evaluate and meta-analyze the effects of high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on athletes of aerobic endurance performance parameters.
PubMed, Web of Science, EBSCO, Embase, and Cochrane databases were searched. The assessment of quality was conducted employing The Cochrane Risk of Bias Assessment Tool, while heterogeneity examination and subgroup analysis were performed. Moreover, regression and sensitivity analyses were executed.
There was no significant difference between the effects of HIIT and MICT on the enhancement of athletes' running economy (RE) (P > 0.05); 1-3 weeks and 4-9 weeks of HIIT were more effective in improving athletes' maximum oxygen uptake (VO2max) (P < 0.05), and 10 weeks and above were not significant (P > 0.05); 1-3 weeks of HIIT was more effective in improving athletes' anaerobic threshold (AT) (P < 0.05), and 4-10 weeks was not significant (P > 0.05); 3 weeks of high-intensity interval training (HIIT) did not significantly enhance athletes' minute ventilation (VE) (P > 0.05), whereas a duration of 6-10 weeks yielded superior results (P < 0.05); 8 weeks of moderate-intensity continuous training (MICT) did not significantly enhance athletes' hemoglobin (Hb) level (P > 0.05), whereas a duration of 2-3 weeks yielded superior results (P < 0.05).
(1) HIIT and MICT have similar effects on enhancing athletes' RE. (2) 6-9 weeks' HIIT was more effective in improving athletes' VO2max and VE, and 3 weeks' HIIT was more effective in improving athletes' AT. (3) Within 3 weeks, MICT was more effective in improving the Hb level of athletes.

系统评价和荟萃分析高强度间歇训练（HIIT）和中等强度持续训练（MICT）对有氧运动耐力运动员表现参数的影响。
检索 PubMed、Web of Science、EBSCO、Embase 和 Cochrane 数据库。采用 Cochrane 偏倚风险评估工具评估质量，同时进行异质性检验和亚组分析。此外，还进行了回归和敏感性分析。
HIIT 和 MICT 对提高运动员的跑步经济性（RE）的影响没有显著差异（P＞0.05）；1-3 周和 4-9 周的 HIIT 更有利于提高运动员的最大摄氧量（VO2max）（P＜0.05），而 10 周及以上则没有显著影响（P＞0.05）；1-3 周的 HIIT 更有利于提高运动员的无氧阈（AT）（P＜0.05），而 4-10 周则没有显著影响（P＞0.05）；3 周的高强度间歇训练（HIIT）对运动员的分钟通气量（VE）没有显著提高（P＞0.05），而 6-10 周的训练则效果更好（P＜0.05）；8 周的中等强度持续训练（MICT）对运动员的血红蛋白（Hb）水平没有显著提高（P＞0.05），而 2-3 周的训练则效果更好（P＜0.05）。
（1）HIIT 和 MICT 对提高运动员的 RE 有相似的影响。（2）6-9 周的 HIIT 更有利于提高运动员的 VO2max 和 VE，而 3 周的 HIIT 更有利于提高运动员的 AT。（3）在 3 周内，MICT 更有利于提高运动员的 Hb 水平。
