Developmental phase
Assessment
Primary outcomes
Change in pleasantness (vitality + stability) of the Two-Dimensional Mood Scale (TDMS) before and after walking on each surface (value immediately after walking minus value immediately before walking)
Key secondary outcomes
(1) Changes in TDMS vitality, stability, and arousal before and after walking
(2) Heart rate, RMSSD, and HF component during walking (change from seated rest immediately before walking in each condition)
(3) Questionnaire ratings of comfort/discomfort, ease of walking, and footing stability, and impression ratings using the semantic differential method for each surface (after completing all three conditions)
(4) Preference for each surface (after completing all three conditions)

Interventions/Control_1
Walking on natural grass: Participants wear identical sandals (with socks) and walk for 5 minutes (approx. 350-400 m) around a flat loop course of approx. 40 m bounded by pylons, in time with a metronome (120 BPM), after 5 minutes of seated rest. Conducted once. The order of the three conditions is randomly allocated across all 6 possible sequences with 3 participants each (cross-over). At least 10 minutes (including transfer and rest) separate conditions.
Interventions/Control_2
Walking on artificial turf: Participants wear identical sandals (with socks) and walk for 5 minutes (approx. 350-400 m) around a flat loop course of approx. 40 m bounded by pylons, in time with a metronome (120 BPM), after 5 minutes of seated rest. Conducted once. The order of the three conditions is randomly allocated across all 6 possible sequences with 3 participants each (cross-over). At least 10 minutes (including transfer and rest) separate conditions.
Interventions/Control_3
Walking on asphalt (control condition): Participants wear identical sandals (with socks) and walk for 5 minutes (approx. 350-400 m) around a flat loop course of approx. 40 m bounded by pylons, in time with a metronome (120 BPM), after 5 minutes of seated rest. Conducted once. The order of the three conditions is randomly allocated across all 6 possible sequences with 3 participants each (cross-over). At least 10 minutes (including transfer and rest) separate conditions.
