Nintendo of America announced a strategic partnership with the American Heart Association this morning, effectively adding the AHA stamp of approval to all retail boxes of Wii Fit Plus, Wii Sports Resort, and the Nintendo Wii itself. "The brand serves as a chance to remind people about the benefits of a healthy approach to living and how active-play video games can be an integral part of a healthy lifestyle," the partnership's official website explains.

In addition to the marketing partnership, the AHA and Nintendo will host a "multidisciplinary summit of representatives from a variety of fields ... to take a closer look at the synergies and benefits of active-play video games," entitled the "Innovation Summit." No details have been provided on when and where said summit will occur. Finally, various "active-play Nintendo video games" will be available to play at select "Start! Heart Walk" events this fall.

Also, no, Nintendo hasn't explained the Vitality Sensor yet.
