Abstract

Purpose: This meta-analysis aims to assess the impact of ischemic preconditioning (IPC) on physical fitness and performance, with a focus on its specific role in aerobic endurance, anaerobic endurance, explosive power and strength.

Methods: Systematic searches were conducted across multiple databases (CNKI, CBM, Cochrane Library, Web of Science, PubMed, and Embase) up to September 6, 2023. We included studies that employed randomized controlled trial methods and sham ischemic preconditioning as the placebo group, and two reviewers independently screened literature and extracted data, using Review Manager 5.3 for analysis.

Results: This meta-analysis comprises 27 articles with 405 individuals, selected according to specified criteria. IPC significantly increased the blood lactate concentration after anaerobic speed endurance exercise (MD = 0.74, P = 0.03), the blood lactate concentration after incremental exercise (MD = 0.49, P = 0.04), the blood lactate concentration after muscular endurance exercise (MD = 0.68, P = 0.02), and the one-repetition maximum (MD = 1.38, P = 0.00001). Furthermore, it also significantly shortened completion time of the exercises primarily powered by glycolysis (MD = - 0.49, P = 0.01) and completion time of the exercises primarily powered by aerobic system (MD = - 7.27, P = 0.05), while marginally prolonging time to exhaustion (MD = 22.68, P = 0.08). However, IPC had no significant effect on maximum oxygen uptake, blood lactate concentration in fixed-load aerobic endurance exercise, peak power, or peak aerobic power, nor on completion time of the exercises primarily powered by phosphagen system.

Conclusion: IPC could serve as a method to enhance physical performance, particularly for exercises primarily powered by aerobic system and glycolysis. Future research might explore how various cycles, locations, and widths of IPC affect the physical performance of participants with different activity levels.

缺血预处理对体能和表现的影响：对健康成年人的荟萃分析。

目的：本荟萃分析旨在评估缺血预处理（IPC）对体能和表现的影响，重点关注其在有氧耐力、无氧耐力、爆发力和力量方面的具体作用：截至 2023 年 9 月 6 日，我们在多个数据库（CNKI、CBM、Cochrane 图书馆、Web of Science、PubMed 和 Embase）中进行了系统检索。我们纳入了采用随机对照试验方法和假缺血预处理作为安慰剂组的研究，两位审稿人独立筛选文献并提取数据，使用Review Manager 5.3进行分析：本荟萃分析包括 27 篇文章，共 405 人，按照特定标准筛选。IPC能明显提高无氧速度耐力运动后的血液乳酸浓度（MD = 0.74，P = 0.03）、增量运动后的血液乳酸浓度（MD = 0.49，P = 0.04）、肌肉耐力运动后的血液乳酸浓度（MD = 0.68，P = 0.02）以及单次重复最大值（MD = 1.38，P = 0.00001）。此外，它还明显缩短了主要由糖酵解驱动的运动的完成时间（MD = - 0.49，P = 0.01）和主要由有氧系统驱动的运动的完成时间（MD = - 7.27，P = 0.05），同时略微延长了力竭时间（MD = 22.68，P = 0.08）。然而，IPC对最大摄氧量、固定负荷有氧耐力运动中的血液乳酸浓度、峰值功率或峰值有氧功率以及主要由磷酸原系统驱动的运动的完成时间均无明显影响：IPC可作为一种提高体能表现的方法，尤其适用于主要由有氧系统和糖酵解驱动的运动。未来的研究可能会探索 IPC 的不同周期、位置和宽度如何影响不同活动水平的参与者的体能表现。

期刊介绍： The European Journal of Applied Physiology (EJAP) aims to promote mechanistic advances in human integrative and translational physiology. Physiology is viewed broadly, having overlapping context with related disciplines such as biomechanics, biochemistry, endocrinology, ergonomics, immunology, motor control, and nutrition. EJAP welcomes studies dealing with physical exercise, training and performance. Studies addressing physiological mechanisms are preferred over descriptive studies. Papers dealing with animal models or pathophysiological conditions are not excluded from consideration, but must be clearly relevant to human physiology.
