Study Arms (2)

Game-based intervention

EXPERIMENTAL

This arm will receive the game intervention, which will include provision of a mobile smartphone device, cellular data service, the game application loaded onto the device, credit to load approximately 40-50 songs onto the device, headphones, and an armband for wearing the device. Participants will also receive weekly counseling calls.

Behavioral: Game-based interventionDevice: Smartphone

Wait list control

NO INTERVENTION

This group will receive no intervention until after completion of the final assessment of the randomized trial. Then, they will receive the full intervention.

Interventions

Investigators will provide participants with a smartphone and required accessories (gift card for downloading the game application and music, headphones, armband). The game, "Zombies, Run!" encourages walking/jogging by playing music interspersed with a continuous narrative. Periodic "zombie chases" encourage brief interval training. Participants will set goals to increase their activity and receive weekly brief counseling phone calls to provide feedback.

Limitations and Caveats

This was a pilot/feasibility study. Sample sizes for the maximal fitness tests and blood pressure were low due to difficulties with feasibility for those measures. Analyses used the intent to treat principle.
