| 概要 | We examined whether tissue oxygen index (TOI) in muscle interacts through oscillation with factors related to oxygen in the cardiorespiratory system. For this examination, coherence and phase difference between the TOI in the vastus lateralis and heart rate (HR) and between TOI and arterial oxygen saturation (SpO2) were sequentially determined during recovery (2–60min) after severe cycle exercise with a workload of 7.5% of body weight for 20s. Significant coherence between TOI and HR was obtained in the very low frequencies (LF) band (approximate range: 0.002–0.03Hz) and in the LF band (approximate range: 0.06–0.12Hz). The phase difference was negative in the LF band and positive in the very LF band. The coherence between TOI and SpO2 was significant in the very LF band. The phase difference was negative. There were no sequential changes in these coherences and phase differences. The results suggest that TOI in skeletal muscle interrelates with factors related to the heart and lungs. |
