本研究的目的是比较早期心肌梗死后 (n = 12; MI) 和年龄匹配的无 MI 老年受试者 (n = 12; CON) 在坡道自行车运动期间多个腿部肌肉的肌肉氧动态。在股外侧肌远端 (VLd)、股外侧肌近端 (VLp)、股直肌 (RF)、股内侧肌 (VM)、腓肠肌内侧肌 (GM) 和胫骨前肌 (TA) 连续监测肌肉氧饱和度 (SmO2)、脱氧血红蛋白浓度 (Δdeoxy-Hb) 和总血红蛋白浓度 (Δtotal-Hb)通过近红外空间分辨光谱分析肌肉。在给定的绝对工作负荷下，与 CON 相比，MI 中 VLd、VLp、RF 和 VM 处观察到更高的 SmO2。同时，在 MI 中，VLd、VLp 和 VM 的脱氧 Hb 低于 CON。与大腿肌肉相比，GM 组和 TA 组之间的肌肉氧动力学相似。总血红蛋白 (total-Hb) 在任何测量部位均未发现显着差异。这些结果表明，在 MI 肌肉中观察到没有肌肉脱氧，特别是在大腿肌肉中，但在小腿肌肉中却没有。
The aim of this study was to compare the muscle oxygen dynamics between early post-myocardial infarction (n = 12; MI) and age-matched elderly subjects without MI (n = 12; CON) in several leg muscles during ramp cycling exercise. Muscle oxygen saturation (SmO2), deoxygenated-hemoglobin concentration (∆deoxy-Hb), and total-hemoglobin concentration (∆total-Hb) were monitored continuously at the distal site of vastus lateralis (VLd), proximal site of the vastus lateralis (VLp), rectus femoris (RF), vastus medialis (VM), gastrocnemius medialis (GM), and tibialis anterior (TA) muscles by near infrared spatial resolved spectroscopy. At given absolute workloads, higher SmO2was observed at VLd, VLp, RF, and VM in MI, compared to CON. Simultaneously, in MI, deoxy-Hb was lower at VLd, VLp, and VM than CON. In contrast to the thigh muscles, muscle oxygen dynamics were similar between groups in GM and TA. In total-Hb, no significant differences were found at any measurement sites. These results demonstrated that the absence of muscle deoxygenation was observed in MI muscles, especially in the thigh muscles, but not in the lower leg muscles.
