Key result
Treadmill running increased the postexercise threshold for cutaneous vasodilation by 0.19 to 0.53 degrees C above no-exercise resting values (P < 0.05).
Why the study?
Does exercise alter the postexercise esophageal temperature threshold for onset of cutaneous vasodilation through active vasodilator activity in humans?
Population
9 subjects
Comparison

May delay postexercise heat dissipation; hypothesis-generating for active vasodilator mechanisms.
Does exercise alter the postexercise esophageal temperature threshold for onset of cutaneous vasodilation through active vasodilator activity in humans?
p-value: p=< 0.05
The postexercise increase in the onset threshold for cutaneous vasodilation is likely mediated through an alteration of active vasodilator activity rather than adrenergic vasoconstrictor activity.
Kenny et al. (2003) studied this question. Treadmill running vs. No-exercise (seated resting for 15 min) was evaluated on Postexercise esophageal temperature threshold for onset of cutaneous vasodilation (p=< 0.05). Treadmill running increased the postexercise threshold for cutaneous vasodilation by 0.19 to 0.53 degrees C above no-exercise resting values (P < 0.05).
