Long-distance runners with exercise-induced hypertension (EIH) are at increased risk for cardiovascular complications. Although blood flow restriction (BFR) training has shown promise in improving vascular function, hemodynamic response, and cardiorespiratory fitness, its effects in EIH runners remain understudied. This study aimed to evaluate the effects of BFR training on cardiovascular responses and exercise performance in this population as a potential non-pharmacological therapy. Middle-aged male long-distance runners aged 40-65 with peak systolic blood pressure (SBP) ≥ 210 mmHg during graded exercise testing were randomly assigned to either a BFR group ( = 18) or a non-BFR control group ( = 15) using a computer-generated random sequence. There were no significant differences in baseline characteristics between the groups. Both groups performed aerobic training at 40-60% HRR for 20 min twice weekly for 8 weeks. SBP, diastolic blood pressure (DBP), rate pressure product (RPP), ventilatory threshold (VT), VO, and perceived exertion were assessed before and after the intervention at rest, during exercise, and during recovery. Compared to the non-BFR group, the BFR group showed statistically significant reductions in resting and maximal SBP and DBP ( < 0.05), along with significant increases in VO and VT ( < 0.05). During submaximal exercise and post-exercise recovery, SBP and RPP were significantly lower in the BFR group ( < 0.05). The reductions in maximal SBP and DBP were significantly greater in the BFR group than in the control group. BFR training led to reduced myocardial workload and enhanced cardiovascular efficiency in male runners with EIH. These findings suggest that BFR training may be a viable non-pharmacological therapy for mitigating cardiovascular risks associated with EIH. Future studies should explore the long-term effects of BFR in broader populations and assess its applicability in clinical settings.
患有运动性高血压（EIH）的长跑运动员发生心血管并发症的风险增加。尽管血流限制（BFR）训练在改善血管功能、血流动力学反应和心肺适能方面已显示出前景，但其对EIH跑步者的影响仍研究不足。本研究旨在评估BFR训练对该人群心血管反应和运动表现的影响，作为一种潜在的非药物治疗方法。在分级运动试验中收缩压峰值（SBP）≥210 mmHg的40 - 65岁中年男性长跑运动员，使用计算机生成的随机序列随机分为BFR组（n = 18）或非BFR对照组（n = 15）。两组间基线特征无显著差异。两组均每周进行两次有氧运动训练，强度为心率储备（HRR）的40 - 60%，每次20分钟，共8周。在干预前后的静息状态、运动期间和恢复期间，评估SBP、舒张压（DBP）、心率血压乘积（RPP）、通气阈值（VT）、最大摄氧量（VO₂）和主观用力程度。与非BFR组相比，BFR组静息和最大SBP及DBP有统计学显著降低（P < 0.05），同时VO₂和VT有显著增加（P < 0.05）。在次最大运动和运动后恢复期间，BFR组的SBP和RPP显著更低（P < 0.05）。BFR组最大SBP和DBP的降低幅度显著大于对照组。BFR训练可降低EIH男性跑步者的心肌负荷并提高心血管效率。这些发现表明，BFR训练可能是减轻与EIH相关心血管风险的一种可行的非药物治疗方法。未来的研究应探讨BFR在更广泛人群中的长期影响，并评估其在临床环境中的适用性。
