Hemoglobin near-infrared spectroscopy and surface EMG study in muscle ischaemia and fatiguing isometric contraction

摘要

Background. To assess how muscle ischaemia and isometric fatiguing contraction influence oxygen content in striated muscle. Methods. We simultaneously measured changes in hemoglobin Near-infrared (NIR) spectroscopy and in surface EMG before, During, and after muscle ischaemia and ischaemia plus mus- Cle isometric fatiguing contraction. Seventeen healthy male Subjects (awge range: 19-40 yrs) were examined in our Clinical Neurophysiology Unit.
