Why the study?
Does dynamic exercise increase skeletal muscle interstitial adenosine concentrations in humans?
Population
Humans undergoing forearm dynamic exercise (n=14 for 50% MVC, n=7 for 15% MVC, n=4 for resting estimation)

Supports adenosine as metabolic signal in exercising muscle; hypothesis-generating for vasodilation mechanisms.
Does dynamic exercise increase skeletal muscle interstitial adenosine concentrations in humans?
Microdialysis effectively estimates muscle interstitial adenosine, which increases significantly during dynamic exercise and further with ischemia, supporting its role as a metabolic signal.
Costa et al. (2000) studied this question.
