to the limited availability of DU and the sum of the costs that arise with additional equipment. An alternative solution to assess changes in blood volume and pulse pressure is pulse oximetry (PO). The PO is a clinically established easy-to-use low-cost method. Implementing this method into BFR

(55%, 65%, 75%, and 85% of VO 2 max) in athletes. These concentrations were corrected by a decrease in blood volume. Total IGF-1 increased during exercise when its values were not corrected for blood volume. When the results were corrected for blood volume, there was no change in total IGF-1

delivery to and extraction by the muscle, while [THb] serves as an indicator of local blood volume. 15 The deoxyhemoglobin concentration ([HHb]), representing muscle O 2 extraction, was computed from SmO 2 and [THb] using the following equation: [HHb] = [THb] − SmO 2  × [THb]. 15 Baseline SmO 2 and

promotes the suppression of the renin–angiotensin system, 33 – 35 which leads to increased blood volume and, consequently, increased distensibility of the cardiac chambers. 36 This, in turn, stimulates a reduction in circulating norepinephrine and vasopressin levels, besides the activity of plasmatic

These observations of reduced HR are consistent with others. 14 , 16 The reduction in HR under temperate conditions may possibly be explained by an increase in blood volume and/or enhanced thermoregulation. 29 It is possible then that similar between-condition reductions in HR under

Brain regions showing increased GM volumes associated with larger amount of PA are also those that are the most vulnerable to aging and that show early structural
