Metabolic requirements of interactive video game cycling.

Background: Interactive video game exercise leads to improved exercise adherence and health-related physical fitness in comparison to traditional stationary cycling. It has been postulated that interactive video game exercise has greater metabolic requirements than traditional cycling; however, this has not been tested to date.

Purpose: To examine the metabolic requirements of interactive video game exercise in comparison to traditional stationary cycling at matched incremental workloads.
