To assess how muscle ischaemia and isometric fatiguing contraction influence oxygen content in striated muscle. We simultaneously measured changes in hemoglobin near-infrared (NIR) spectroscopy and in surface EMG before, during, and after muscle ischaemia and ischaemia plus muscle isometric fatiguin...
