Differences in Step Counts, Motor Competence, and Enjoyment Between an Exergaming Group and a Non-Exergaming Group

OBJECTIVE

The purpose of this study was to examine the effect of an exergaming program on physical activity, motor competence, and enjoyment in preschool children.

MATERIALS AND METHODS

A sample of 65 preschool children was recruited from an urban preschool located in the Western United States. Children were randomly assigned to either an exergaming (n = 36) or a free-play group (n = 29). The intervention was 30 min/day, 5 days/week for 12 weeks for both groups, and all outcome variables were measured once during the final week of the intervention. The exergaming program included three active videogames: GoNoodles, Adventure to Fitness, and Cosmic Kids Yoga. Children in the free-play group were offered a variety of sport activities. School-day step counts were recorded using pedometers, motor competence was assessed by the Test for Gross Motor Development-Edition 3 (TGMD-3), and enjoyment was accessed using one subscale of the Intrinsic Motivational Inventory. A 2 × 2 multivariate analysis of variance (MANOVA) test was employed to examine the differences between sexes and groups on the outcome variables.

RESULTS

The omnibus MANOVA yielded a statistically significant multivariate group main effect (F = 3.71, P = 0.016). Follow-up tests revealed statistically significant differences between groups on average school step counts (mean difference = 785 steps, P = 0.003, d = 0.68) and total TGMD-3 scores (mean difference = 8.7, P = 0.019, d = 0.51), with the exergaming group displaying higher mean scores compared with the free-play group.

CONCLUSION

Young children who were randomly assigned to the exergaming group demonstrated higher school-day step counts and higher motor competence levels compared with the free-play group. These results support the use of this modality in childcare settings.

Games for Health for Children-Current Status and Needed Research

Videogames for health (G4H) offer exciting, innovative, potentially highly effective methods for increasing knowledge, delivering persuasive messages, changing behaviors, and influencing health outcomes. Although early outcome results are promising, additional research is needed to determine the game design and behavior change procedures that best promote G4H effectiveness and to identify and minimize possible adverse effects. Guidelines for ideal use of different types of G4H by children and adolescents should be elucidated to enhance effectiveness and minimize adverse effects. G4H stakeholders include organizational implementers, policy makers, players and their families, researchers, designers, retailers, and publishers. All stakeholders should be involved in G4H development and have a voice in setting goals to capitalize on their insights to enhance effectiveness and use of the game. In the future, multiple targeted G4H should be available to meet a population's diverse health needs in developmentally appropriate ways. Substantial, consistent, and sophisticated research with appropriate levels of funding is needed to realize the benefits of G4H.
