Key Points

To determine how separate components of an enriched environment—specifically voluntary exercise versus object exploration—influence the temporal dynamics and progression of anxiety-like behaviors in rodents.
Male rats were housed for 4 weeks in one of four conditions: standard environment (SE), complete enriched environment with wheel and objects (EE), EE with running wheel only (EER), or EE with objects only (EEO).
Locomotor and physical activity were monitored during housing, including rearing behavior and object interaction time.
Anxiety-like behavior was evaluated using a 10-minute elevated plus maze (EPM) test divided into five consecutive phases for time-resolved analysis.
Physical activity was significantly higher in wheel-containing groups (EE and EER) versus the SE group, while rearing increased across all enriched groups and object interaction time was higher in EEO than EE.
EE and EER groups spent significantly more time exploring open arms during early test phases compared with controls (p < 0.05).
EEO rats exhibited significantly greater open-arm exploration during later test phases compared with the SE group (p = 0.0068).
