Active video games as an exercise tool for children with cystic fibrosis

Area of Science:

• Pediatric Exercise Physiology
• Rehabilitation Medicine
• Digital Health Interventions

Background:

• Active video games are utilized in pediatric hospitals as exercise modalities for children diagnosed with cystic fibrosis (CF).
• The specific exercise intensity levels achieved during gameplay in this vulnerable population remain largely unquantified.

Purpose of the Study:

• To evaluate the exercise intensity of active video games in children with cystic fibrosis.
• To compare the energy expenditure of playing Nintendo Wii™ Sports Boxing and Wii Fit Free Jogging between children with CF and healthy controls.

Main Methods:

• Thirty children with CF (mean age 12.3 years) and age/gender-matched controls participated.
• Oxygen consumption (V˙O2) and heart rate were measured using portable indirect calorimetry during gameplay.
• Metabolic equivalents (METs) were calculated to quantify exercise intensity.

Main Results:

• Nintendo Wii™ Sports Boxing elicited light-intensity physical activity (2.46 METs).
• Nintendo Wii Fit Free Jogging generated moderate-intensity physical activity (4.44 METs).
• No significant differences in energy expenditure were observed between the CF group and controls during active video game play.

Conclusions:

• Active video games represent a viable source of light to moderate intensity physical activity for pediatric patients with cystic fibrosis.
• These findings support the integration of exergaming into CF management strategies for improving physical activity levels.
