摘要

Research on ischemic preconditioning (IPC) within applied exercise physiology has expanded considerably over the past few decades. While IPC demonstrates potential for enhancing exercise performance and accelerating muscle recovery, its widespread adoption is currently hindered by substantial heterogeneity in protocols and applications. Notably, recent evidence suggests that the reported ergogenic effects of IPC become less apparent in studies utilizing a three-arm experimental design (i.e., IPC, placebo and control). This variability compromises reproducibility and complicates the establishment of IPC as a reliable physiological stimulus and an ergogenic aid. Consequently, this narrative review aims to advance the field by identifying gaps, proposing methodological standards and encouraging the standardization of protocol design. We evaluate critical parameters, including cuff width, inflation pressure, number of cycles, and the duration of occlusion and reperfusion, while addressing the implications of experimental design and the confounding influence of placebo effects. As significant questions remain regarding the optimization of IPC for physical work capacity and muscle recovery, a standardized framework is urgently required to guide future research and evidence-based practice in human performance physiology.
