Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to examine whether exercising in a biophilic environment - a space designed to include natural elements like real plants, simulated sunlight, nature sounds, and outdoor views - can improve exercise performance and enjoyment compared to a standard indoor gym environment in male college students age 18-25 who have regularly exercised prior.

The main question it aims to answer is: "Can biophilic design enhance the physical and mental benefits of indoor exercise?"

Researchers will compare the two environments to see if there is any changes in exercise performance and enjoyment for each participant.

Participants will complete a treadmill fitness test in both settings to compare physical outcomes like maximal aerobic capacity, so the maximal amount of oxygen one can use during exercise, as well as perceived effort. After each treadmill test participants will be given surveys where they will be asked to evaluate their mood and enjoyment in that environment.

Intervention Model

CROSSOVER

Participants will be randomized into the biophilia group or the traditional group - that will be the environment that they start in. They will then go through a week wash out and then will go into the other environment for their exercise test.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Biophilic Design

The exercise environment will be designed with nature elements, real and artificial plants, a landscape wall paper, simulated sunlight, and nature sounds.

Group Type EXPERIMENTAL

Intervention Type OTHER

This intervention focused around the environmental design of the exercise room.

Traditional Exercise Environment

The exercise environment will be designed like a traditional indoor gym setting. With a treadmill at the center and no other purposeful design elements.
