- Primary Outcome Measures
Name Time Method 1. Oscillatory index;<br /><br>2. Brachial artery blood flow patterns (antegrade and retrograde shear rate).<br><br /><br /><br>Diameter of the right brachial artery and velocity of the blood flow will be examined using the non-invasive echo-Doppler. A 2-minute baseline recording will be acquired before starting the training session. A recording of the first ten minutes of the exercise session will be acquired continuously, while 1-minute ultrasound recordings are made every 5 minutes throughout the rest of the exercise session.
- Secondary Outcome Measures
Name Time Method 1. Thermoregulatory changes (skin and core body temperature);<br /><br>2. Autonomic function (heart rate variability).
