  Figure 1. Representative profile of the deoxyhemoglobin ([HHb]) signal analysis during and subsequent to cuff occlussion.Baseline, 2 min period previous to the occlusion; occlusion, five min period during cuff inflation at 250 mmHg; reperfusion, 8 min period after cuff release; AUCocc, area under the curve of deoxyhemoglobin during occlusion period; AACrep, area above the curve of deoxyhemoglobin during reperfusion.

  Figure 2. Difference between young untrained and trained individuals for the area under the curve of deoxyhemoglobin signal during occlusion (AUCocc) and area above the curve of deoxyhemoglobin signal during reperfusion (AACrep). Panel A shows the smaller area under the curve of deoxyhemoglobin signal during occlusion period of trained compared to the untrained participants (mean ± SD). Panel B depicts the average profile of the deoxyhemoglobin signal during the vascular occlusion test of trained and untrained participants, highlighting the smaller area under the curve of deoxyhemoglobin during occlusion period in the trained participants (filled in gray) when compared to untrained individuals. Panel C shows the smaller area above the curve of deoxyhemoglobin during reperfusion period of trained participants when compared to their untrained counterparts (mean ± SD). Panel D depicts the smaller area above the curve of deoxyhemoglobin during reperfusion of trained compared to untrained participants (filled in gray). *Different from young untrained (P < 0.05)
