Suprasystolic (300 mmHg) cuff compressions
10 minutes of ECG-gated repeated suprasystolic (300 mmHg) cuff compressions, with inflation occurring every other heart cycle. These cuff compressions may be triggered 0 seconds, 0.2 seconds, or 0.4 seconds from the R spike (systole) on the ECG signal.
Handgrip exercise
10 minutes of ECG-gated rhythmic handgrip exercise at 30% maximal voluntary contraction, with contraction occurring every other heart cycle
Passive heat stress
10 minutes of passive heat stress at 42 degrees Celsius with a commercially available heating blanket
