Despite the longstanding knowledge that blood flow increases in proportion to metabolic activity of skeletal muscle, the underlying mechanisms that govern this response have only recently been identified.1 Given the role of endothelial cells in mediating exercise hyperemia,2 interest has been focused on endothelium-derived vasodilation occurring via the synthesis of nitric oxide (NO) and vasodilating prostaglandins (PGs; i.e. prostacyclin) or endothelium- derived hyperpolarization. A number of studies performed in humans have established a minimal-to-modest role for NO and PGs during mild- and moderate- intensity exercise. In animal preparations, prevention of hyperpolarization attenuates contraction-induced hyperemia; however, performing similar studies …

The purpose of this study was to determine the energy cost of playing select games on the Nintendo Wii for 30 contiguous minutes and whether or not the physical interaction of the participant with the gaming system and subsequent physiologic intensity diminishes with playing time.
