Primary Outcome Measures

Name	Time	Method
<p>magnitude of decline in the combined oxygenated hemoglobin (HbO2) and myoglobin<br /><br>(MbO2) signal from the near-infrared spectroscopy during the cold pressor test<br /><br>at rest and during handgrip exercise at 10 and 30% MVC combined with the cold<br /><br>pressor test. </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>- Brachial artery blood flow (using non-invasive ultrasound as a secondary<br /><br>measure of exercise-induced blood flow during handgrip and performance of the<br /><br>cold pressor test)<br /><br>- Mean arterial blood pressure (Nexfin, contra-lateral arm) (to control for<br /><br>potential differences in the blood pressure response between the subsequent<br /><br>tests)<br /><br>- Forearm blood flow using plethysmography (contra-lateral arm) </p><br>
