Summary

The goal of this randomized crossover trial is to compare the differences in psychological and physiological effects of walking in two different outdoor environments (urban/suburban commercial environments vs. urban/suburban nature areas/preserves) in adults with prediabetes. The main questions it aims to answer are:

* Do psychological measures of stress, anxiety, and affect improve more in one type of outdoor environment over the other?
* Do physiological measures of stress improve more in one type of outdoor environment over the other?

As this is a crossover trial, participants will serve as their own controls. Researchers will compare both the psychological and physiological effects walking in the two types of outdoor environments.

Participants will:

* Walk 150-minutes per week for six weeks in each of the two outdoor conditions.
* Visit the clinic four times, including before and after each six-week walking period.
* Collect saliva samples immediately proceeding or following the four clinic visits.
* Return to their pre-study level of physical activity for a 5-week washout period between each of the two walking interventions.

Interventions

BEHAVIORAL

Nature-based Walking

All participants will be asked to walk three to five times per week for 30-50 minutes per walk, totaling 150 min/week, at moderate intensity over a 6-week period in a designated nature-based, or 'green', urban environment.

BEHAVIORAL

Built-environment/Commercial Walking

All participants will be asked to walk three to five times per week for 30-50 minutes per walk, totaling 150 min/week, at moderate intensity over a 6-week period in a designated built-environment/commercial, or 'Gray', urban environment.
