We sought to determine whether a 9-day remote ischemic preconditioning (IPC) causes improvements in exercise performance, energetics, and blood pressure. Ten participants (mean age 24 ± 4 years) had no changes in aerobic capacity (preintervention: 38 ± 10 mL/(kg·min)(-1) vs. postintervention: 38 ± 10 mL/(kg·min)(-1)), blood pressure (preintervention: 112 ± 7/66 ± 6 mm Hg vs. postintervention: 112 ± 10/62 ± 5 mm Hg), cardiac phosphocreatinine-to-adenosine-triphosphate ratio (preintervention: 2.1 ± 0.5 vs. postintervention: 2.3 ± 0.4), and postexercise skeletal muscle phosphocreatine recovery (preintervention: 34 ± 11 s vs. postintervention: 31 ± 11 s). Short-term remote IPC may be ineffective in improving these outcomes.
我们试图确定为期9天的远程缺血预处理（IPC）是否能改善运动表现、能量代谢和血压。10名参与者（平均年龄24±4岁）的有氧能力（干预前：38±10 mL/（kg·min）⁻¹ 对比干预后：38±10 mL/（kg·min）⁻¹）、血压（干预前：112±7/66±6 mmHg对比干预后：112±10/62±5 mmHg）、心肌磷酸肌酸与三磷酸腺苷的比值（干预前：2.1±0.5对比干预后：2.3±0.4）以及运动后骨骼肌磷酸肌酸恢复情况（干预前：34±11秒对比干预后：31±11秒）均无变化。短期远程IPC可能无法有效改善这些指标。
