Physiological Cost of Exergaming
What is Exergaming?
Exergaming and Physiological Cost
• It’s recommended that adults should complete 150 minutes of moderate
intensity activity per week (Haskell, et al., 2007; ACSM, 2014), however these guidelines
are not currently met.
• Video games are played 3-7 times per week, each session lasting on average
1.9 hours among 11-15 year olds (Pratchett, 2005).
• Active Video Games (AVGs) may offer a potential solution.
• Recent evidence suggests AVGs may be physiologically effective to increase
fitness (Bosch, et al., 2012; Graves, et al., 2008; O’Donovan and Hussey, 2012), however the
majority of research has been conducted on the Wii
• The activity must be fun and enjoyable to encourage intrinsic motivation (Atkins,
et al., 2013; Ullrich-French and Smith, 2009).
• Advances in AVGs have led to the development of the Xbox Kinect - a freely
moveable, hands free gaming system which promotes full body movements.
MET’s
Conclusion/discussion
90 minute gaming – too long?
METs could have been higher intensity and dropped over the 90 minutes
Wii control flicking of wrist could have impact on EE
Assessing the physiological cost of active video games (Xbox Kinect™) versus sedentary video games in young
healthy males
METHODOLOGYSample
Single Player: 19 healthy male participants (Age: 23 ± 3 years, Height: 178 ± 6cm,
Weight: 79 ± 15kg).
Multiplayer: 9 healthy male participants (Age: 24 ± 4 years, Height: 178 ± 7cm,
Weight: 79 ± 16kg)
Protocol
Participants visited lab on 3 occasions :-
1. O2max Test
2. Single Player Gaming sedentary versus AVG
Protocol
O2max Test
• 5 minute warm up
• 10kph start
• 1kph increments every 3 minutes
• 1% inclination
• Continuous expired gas and heart rate collection
• RPE gathered after each 3 minute stage
Gaming
• Played FIFA and CoD on Xbox 360 and River Rush, Reflex Ridge and Boxing on Kinect.
• Continuous HR and gas collection
• FIFA and CoD played for 15 minutes (RPE collected every 3 minutes, last 30 seconds of each 3 minute stage
averaged for HR and O2)
• 3 rounds played on exergames (RPE collected after each round, last 30 seconds of each round averaged for HR and
O2).
• Game order randomised

Discussion
Main Findings
• Exergames caused significantly greater physiological
responses than sedentary gaming (p<0.01)
• AVG elicited moderate levels of exercise intensity (64-
72%HRmax) in line with current recommended
physical activity guidelines.
• Reflex Ridge was the most physiologically demanding
game
