Pre-post changes in physiological, cognitive, and motivational outcomes following an active video game intervention in adolescents and adults: a pilot study.
Williams A, Wadsworth D, Geetha T • Frontiers in public health • 2026
An 8-week low-dose active video game intervention produced modest and heterogeneous effects, with more favorable physiological responses observed in adolescents than adults, but overall commercially available AVGs appear insufficient as a standalone intervention for improving broader cognitive, fitness, or motivational outcomes.
Key Findings
Results
Adolescents demonstrated significant changes in body composition, with increased fat-free mass and reduced fat mass following the 8-week intervention.
Changes in body composition were statistically significant at p < 0.05
Body composition was measured using bioelectrical impedance analysis
The authors cautioned that 'changes in adolescent body composition likely reflect normal developmental processes and cannot be attributed solely to the intervention'
This was an uncontrolled pilot study, limiting causal inference
Results
No significant body composition changes were observed in adults following the 8-week active video game intervention.
Adults showed no significant pre-post changes in fat mass or fat-free mass
Body composition was measured by bioelectrical impedance analysis
The intervention required at least 60 minutes of gameplay per week
The differential response between adolescents and adults suggests age-related heterogeneity in physiological outcomes
Results
Adults exhibited a significant decline in left-hand grip strength that did not remain significant after correction for multiple comparisons.
The initial p-value for left-hand grip strength decline in adults was p = 0.037
The finding did not remain significant after correction for multiple comparisons
Muscular strength remained stable in adolescents
Handgrip strength was assessed as the measure of muscular strength
Results
No robust changes were observed in cognitive or balance outcomes after statistical adjustment.
Cognitive and fitness performance were assessed using the Sway application
Outcome measures included balance, reaction time, and executive function tasks
Any initial changes did not remain significant after adjustment for multiple comparisons
Both adolescents and adults were assessed on these cognitive and balance outcomes
Results
Motivational regulation and exercise enjoyment remained stable throughout the 8-week intervention.
Psychological and motivational constructs were assessed using Self-Determination Theory-based questionnaires
Psychological constructs were not significantly associated with changes in autonomous motivation
Motivational outcomes were unchanged in both adolescents and adults
Paired t-tests and correlation analyses were used to evaluate changes over time and associations between variables
Methods
The study was an uncontrolled pilot using Ring Fit Adventure on the Nintendo Switch with a minimum dose of 60 minutes of gameplay per week for 8 weeks.
Participants included both adolescents and adults in a home-based setting
The study design was a pre-post uncontrolled pilot with no comparison group
Participants were instructed to engage in at least 60 minutes of gameplay per week
The intervention duration was 8 weeks
The authors identified the low dose and lack of controlled design as key limitations
Conclusions
The authors concluded that active video games appear insufficient as a standalone intervention and recommended future research employ controlled designs, optimize intervention dose, improve adherence, and incorporate structured progression.
Effects were described as 'modest and heterogeneous'
More favorable physiological responses were observed in adolescents than adults
The authors noted that adherence and intervention dose were limitations of the current study
Structured progression was identified as a missing element that could enhance future effectiveness
What This Means
This research examined whether playing Ring Fit Adventure, an active video game for the Nintendo Switch, could improve physical fitness, thinking skills, and motivation in both teenagers and adults over 8 weeks at home. Participants were asked to play at least 60 minutes per week. The study measured body composition, grip strength, balance, reaction time, memory and thinking tasks, and psychological questionnaires about motivation and enjoyment before and after the program.
The results showed that teenagers had changes in body composition — specifically more muscle mass and less fat — but the researchers cautioned these changes may simply reflect normal growth and development rather than being caused by the video game. Adults did not show meaningful changes in body composition, and a temporary drop in grip strength in adults disappeared when stricter statistical standards were applied. Neither age group showed reliable improvements in balance, cognitive performance, or motivation. Exercise enjoyment and motivation levels stayed about the same throughout the program for both groups.
This research suggests that playing active video games at a low dose — just one hour per week — is probably not enough on its own to produce meaningful improvements in fitness, thinking ability, or motivation for most people. The study was also limited by having no control group for comparison, making it hard to know whether any changes were truly caused by the intervention. Future studies would benefit from longer or more intensive programs, better tracking of how much people actually play, and a comparison group to more clearly determine whether active video games can serve as an effective physical activity strategy.
