Abstract

BACKGROUND: The Compendium of Energy Expenditures for Youth assigns MET values to a wide range of activities. However, only 35% of activity MET values were derived from energy cost data measured in youth; the remaining activities were estimated from adult values.

PURPOSE: To determine the energy cost of common activities performed by children and adolescents and compare these data to similar activities reported in the compendium.

METHODS: Thirty-two children (8-11 years old) and 28 adolescents (12-16 years) completed 4 locomotion activities on a treadmill (TRD) and 5 age-specific activities of daily living (ADL). Oxygen consumption was measured using a portable metabolic analyzer.

RESULTS: In children, measured METs were significantly lower than compendium METs for 3 activities [basketball, bike riding, and Wii tennis (1.1-3.5 METs lower)]. In adolescents, measured METs were significantly lower than compendium METs for 4 ADLs [basketball, bike riding, board games, and Wii tennis (0.3-2.5 METs lower)] and 3 TRDs [2.24 m·s-1, 1.56 m·s-1, and 1.34 m·s-1 (0.4-0.8 METs lower)].

CONCLUSION: The Compendium of Energy Expenditures for Youth is an invaluable resource to applied researchers. Inclusion of empirically derived data would improve the validity of the Compendium of Energy Expenditures for Youth.

Abstract 
OBJECTIVES: It has been reported that a higher galvanic skin response is seen when playing video games against another human player than when playing alone, which suggests increased effort. The objectives of this study were to compare energy expenditure when playing two popular active video game consoles, and to compare energy expenditure when playing in single and multiplayer modes.
DESIGN: Crossover trial with randomised playing order.
PARTICIPANTS: Fourteen healthy adults with a mean age of 21 [standard deviation (SD) 3] years.
METHODS AND INTERVENTIONS: Energy expenditure was measured using an indirect calorimeter at rest, during 10minutes of play on Xbox Kinect™ Reflex Ridge in both single and multiplayer modes, and during 10minutes of play on Wii™ Sports Boxing in both single and multiplayer modes.
MAIN OUTCOME MEASURES: Metabolic equivalents (METs), heart rate, oxygen consumption and kilocalories expended.
RESULTS: The energy expenditure during all gaming conditions was of a light intensity. Playing on the Xbox Kinect elicited greater energy expenditure than playing on the Wii [mean difference=0.9 METs, 95% confidence interval (CI) 0.2 to 1.5]. Playing games in multiplayer mode led to greater energy expenditure (mean difference=0.5 METs, 95% CI 0.1 to 0.9) and heart rate (mean difference=7.9 beats/minute, 95% CI 2.0 to 13.8) than playing in single player mode.
CONCLUSIONS: No gaming condition required moderate-intensity activity in this group of young healthy adults. Potential explanations for the difference in energy expenditure seen between consoles and modes are discussed.

Abstract

Background: In the present study we investigated the effect of television watching and the use of activity-promoting video games on energy expenditure in obese and lean children.

Methods: Energy expenditure and physical activity were measured while participants were watching television, playing a video game on a traditional sedentary video game console, and while playing the same video game on an activity-promoting video game console.

Results: Energy expenditure was significantly greater than television watching and playing video games on a sedentary video game console when children played the video game on the activity-promoting console. When examining movement with accelerometry, children moved significantly more when playing the video game on the Nintendo Wii console.

Conclusion: Activity-promoting video games have shown to increase movement, and be an important tool to raise energy expenditure by 50% when compared to sedentary activities of daily living.

Abstract


Purpose: Play of physically active video games may be a way to increase physical activity and/or decrease sedentary behavior, but games are not universally active or enjoyable. Active games may differ from traditional games on important attributes, which may affect frequency and intensity of play. The purpose of this study was to investigate differences in energy expenditure and enjoyment across four game types: shooter (played with traditional controllers), band simulation (guitar or drum controller), dance simulation (dance mat controller), and fitness (balance board controller).

Methods: Energy expenditure (METs) and enjoyment were measured across 10 games in 100 young adults age 18-35 yr (50 women).

Results: All games except shooter games significantly increased energy expenditure over rest (P < 0.001). Fitness and dance games increased energy expenditure by 322% (mean ± SD = 3.10 ± 0.89 METs) and 298% (2.91 ± 0.87 METs), which was greater than that produced by band simulation (73%, 1.28 ± 0.28 METs) and shooter games (23%, 0.91 ± 0.16 METs). However, enjoyment was higher in band simulation games than in other types (P < 0.001). Body mass-corrected energy expenditure was greater in normal weight than in overweight participants in the two most active game types (P < 0.001).

Conclusions: Active video games can significantly increase energy expended during screen time, but these games are less enjoyable than other more sedentary games, suggesting that they may be less likely to be played over time. Less active but more enjoyable video games may be a promising method for decreasing sedentary behavior.

Objective 
To determine the relative effect of interactive digital exercise that features player movement (ie, exergames) on energy expenditure among children of various body mass indexes (BMIs; calculated as weight in kilograms divided by height in meters squared).

Design Comparison study.
Setting GoKids Boston, a youth fitness research and training center located at University of Massachusetts, Boston.

Participants 
Thirty-nine boys and girls (mean [SD] age, 11.5 [2.0] years) recruited from local schools and after-school programs.

Main Exposure
Six forms of exergaming as well as treadmill walking.

Main Outcome Measures 
In addition to treadmill walking at 3 miles per hour (to convert miles to kilometers, multiply by 1.6), energy expenditure of the following exergames were examined: Dance Dance Revolution, LightSpace (Bug Invasion), Nintendo Wii (Boxing), Cybex Trazer (Goalie Wars), Sportwall, and Xavix (J-Mat). Energy expenditure was measured using the CosMed K4B2 portable metabolic cart.

Results
All forms of interactive gaming evaluated in our study increased energy expenditure above rest, with no between-group differences among normal (BMI < 85th percentile) and "at-risk" or overweight (BMI 85th percentile) children (P .05). Walking at 3 miles per hour resulted in a mean (SD) metabolic equivalent task value of 4.9 (0.7), whereas the intensity of exergaming resulted in mean (SD) metabolic equivalent task values of 4.2 (1.6) for Wii, 5.4 (1.8) for Dance Dance Revolution, 6.4 (1.6) for LightSpace, 7.0 (1.8) for Xavix, 5.9 (1.5) for Cybex Trazer, and 7.1 (1.7) for Sportwall. Enjoyment of the games was generally high but was highest for children with BMIs in the highest percentiles.

Conclusion 
All games used in our study elevated energy expenditure to moderate or vigorous intensity. Exergaming has the potential to increase physical activity and have a favorable influence on energy balance, and may be a viable alternative to traditional fitness activities for children of various BMI levels.

Abstract

This study investigated the physical and psychosocial effect of exergaming in community
dwelling older adult women. In a pilot study consisting of a six-week baseline period and a
six-week intervention period, participants (N = 11, mean age = 73.5 years, SD = 9.0) played
Nintendo Wii Sports twice weekly. We measured full body movements using accelerometers,
and assessed psychosocial effects through end-of-study focus group meetings. There were
large self-reported psychological effects related to positive changes in self perception. The
game-play deepened social connections within the group and provided a basis for shared
experiences with younger aged family members. Physically, the game-play showed
significantly higher maximum energy expenditure (t = -4.52, p < 0.05) than baseline, but no significant difference in overall energy expenditure. Findings from the quantitative data showed that Wii-play did not have substantial physical effects; nevertheless, qualitative data revealed that the participants perceived an improved sense of physical, social and psychological wellbeing.

ABSTRACT:

BACKGROUND:

Stroke is one of the leading causes of long-term disability in modern western countries. Stroke survivors often have functional limitations which might lead to a vicious circle of reduced physical activity, deconditioning and further physical deterioration. Current evidence suggests that routine moderate- or vigorous-intensity physical activity is essential for maintenance and improvement of health among stroke survivors. Nevertheless, long-term participation in physical activities is low among people with disabilities. Active video games, such as Nintendo Wii Sports, might maintain interest and improve long-term participation in physical activities; however, the intensity of physical activity among chronic stroke patients while playing Wii Sports is unknown. We investigated the energy expenditure of chronic stroke patients while playing Wii Sports tennis and boxing.

METHODS:

Ten chronic (≥ 6 months) stroke patients comprising a convenience sample, who were able to walk independently on level ground, were recruited from a rehabilitation centre. They were instructed to play Wii Sports tennis and boxing in random order for 15 minutes each, with a 10-minute break between games. A portable gas analyzer was used to measure oxygen uptake (VO2) during sitting and during Wii Sports game play. Energy expenditure was expressed in metabolic equivalents (METs), calculated as VO2 during Wii Sports divided by VO2 during sitting. We classified physical activity as moderate (3-6 METs) or vigorous (> 6 METs) according to the American College of Sports Medicine and the American Heart Association Guidelines.

RESULTS:

Among the 10 chronic stroke patients, 3 were unable to play tennis because they had problems with timing of hitting the ball, and 2 were excluded from the boxing group because of a technical problem with the portable gas analyzer. The mean (± SD) energy expenditure during Wii Sports game play was 3.7 (± 0.6) METs for tennis and 4.1 (± 0.7) METs for boxing. All 8 participants who played boxing and 6 of the 7 who played tennis attained energy expenditures > 3 METs.

CONCLUSIONS:

With the exception of one patient in the tennis group, chronic stroke patients played Wii Sports tennis and boxing at moderate-intensity, sufficient for maintaining and improving health in this population.

Abstract
Limited research documents if new and existing interactive computer gaming "exergaming" increase energy expenditure and cardio-respiratory costs comparable to common exercise modalities. To address this, healthy male volunteers (n = 15) completed six by 12-min test elements: PlayStation2 (PS2(hand)), Nintendo Wii boxing, walk at 5.6 km h(-1), cycle at 120 W, playing an adapted lower limb controlled PS2 (PS2(limb)) and run at 9.6 km h(-1). In addition, they played PS2(limb) for 30 min and performed an incremental treadmill test to exhaustion. Data were analysed using repeated measures ANOVA with post hoc Tukey tests, P < 0.05 inferred significance. PS2(limb) increased energy expenditure (EE) and post-exercise blood lactate (BLa) significantly higher (P < 0.001) than PS2(hand), Wii gaming or walking at 5.6 km h(-1) (EE: 30.3 ± 4.9 vs. 4.7 ± 1.1, 22.0 ± 6.1 and 17.9 ± 1.9 kJ h(-1) kg(-1); BLa: 2.4 ± 1.5 vs. 1.0 ± 0.3, 1.8 ± 0.8 and 0.9 ± 0.2 mmol L(-1)), playing the PS2(limb) raised mean EE over six times greater than PS2(hand). Mean fat and carbohydrate oxidation rates during the 9- to 12-min period playing the PS2(limb) were five and ten times greater than PS2(hand) (0.25 ± 0.10 vs. 0.05 ± 0.10, 1.69 ± 0.52 vs. 0.15 ± 0.14 g min(-1), respectively). PS2(limb) met ACSM guidelines for cardiovascular fitness; however, current Wii technology failed. In conclusion, gaming interactive technology must be adapted or designed to include the lower limbs in order to provide a significant exercise stimulus.

BACKGROUND: Active video games (exergames) increase energy expenditure (EE) and physical activity (PA) compared with sedentary video gaming. The physiological cost and enjoyment of exergaming in adolescents, and young and older adults has not been documented, nor compared with aerobic exercise. This study compared the physiological cost and enjoyment of exergaming on Wii Fit with aerobic exercise in 3 populations.

METHODS: Cardiorespiratory and enjoyment measurements were compared in 14 adolescents, 15 young adults, and 13 older adults during handheld inactive video gaming, Wii Fit activities (yoga, muscle conditioning, balance, aerobics), and brisk treadmill walking and jogging.

RESULTS: For all groups EE and heart rate (HR) of Wii Fit activities were greater than handheld gaming (P < .001) but lower than treadmill exercise. Wii aerobics elicited moderate intensity activity in adolescents, young adults, and older adults with respective mean (SD) metabolic equivalents of 3.2 (0.7), 3.6 (0.8), and 3.2 (0.8). HR during Wii aerobics fell below the recommended intensity for maintaining cardiorespiratory fitness. Group enjoyment rating was greater for Wii balance and aerobics compared with treadmill walking and jogging. CONCLUSIONS: Wii Fit appears an enjoyable exergame for adolescents and adults, stimulating light-to-moderate intensity activity through the modification of typically sedentary leisure behavior.

Abstract
OBJECTIVE: To determine energy expenditure of adults with bilateral spastic cerebral palsy while playing Wii Sports tennis and boxing.

DESIGN: Cross-sectional study.

SETTING: University medical center.

PARTICIPANTS: Five men and 3 women with bilateral spastic cerebral palsy and ambulatory ability (Gross Motor Function Classification System level I or II) participated. The mean participant age ± SD was 36±7 years. Exclusion criteria were comorbidities that affected daily physical activity and fitness, contraindications to exercise, or inability to understand study instructions owing to cognitive disorders or language barriers.

INTERVENTION: Participants played Wii Sports tennis and boxing, each for 15 minutes in random order.

MAIN OUTCOME MEASURE: By using a portable gas analyzer, we assessed energy expenditure by oxygen uptake (Vo(2)) while sitting and during Wii Sports game play. Energy expenditure is expressed in metabolic equivalents (METs), which were calculated as Vo(2) during Wii Sports play divided by Vo(2) during sitting.

RESULTS: Mean ± SD energy expenditure during Wii Sports game play was 4.5±1.1METs for tennis and 5.0±1.1METs for boxing (P=.024). All participants attained energy expenditures greater than 3METs, and 2 participants attained energy expenditures greater than 6METs while playing Wii Sports tennis or boxing.

CONCLUSIONS: Both Wii Sports tennis and boxing seem to provide at least moderate-intensity exercise in adults with bilateral spastic cerebral palsy (GMFCS level I or II). These games, therefore, may be useful as treatment to promote more active and healthful lifestyles in these patients. Further research is needed to determine the energy expenditures of other physically disabled patient groups while playing active video games, and to determine the effectiveness of these games in improving health and daily activity levels.
