Figure Lengend Snippet: Schematic representation of experimental protocol. Arrows illustrate the times in which an ultrasound blood flow measurement was conducted. Blood flow was measured at the common, superficial and profunda femoral arteries and popliteal artery. Core temperature, leg muscle and skin temperatures, leg tissue oxygen saturation, leg skin blood flow and central haemodynamics were measured continuously throughout the protocol. Protocol 1 was conducted during visit A, and protocols 2 and 3 on visit B. The respective visits were randomised and counterbalanced.
Article Snippet: Blood flow was measured at set time points (Figure ) – recording two 12‐s Doppler images – throughout the protocols in the various arteries using a duplex Doppler ultrasound system (Vivid E95, GE Medical Systems, Little Chalfont, UK) with a 9‐MHz linear array transducer probe (GE Medical Systems) at an insonation angle of ≤60°, with sample volume positioned in the centre of the artery.
