Brief Summary

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

The goal of this clinical trial is to investigate how walking in different environments affects the psychophysiological responses to the stress of individuals with coronary artery disease (CAD) according to their weather sensitivity. Awareness about the potential influence of weather sensitivity on the psychophysiological reactions to stress in patients with CAD disease may contribute to the planning and implementation of actions leading to improved medical care services and preventative measures that help to avoid the worsening of health and well-being in the future.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The environment might influence one's course of a disease and health prospective through direct exposure to physical, chemical, social, and psychosocial risk factors, as well as indirectly, through behavior-related changes response to those factors. Classical risk factors only partially account for variations in the occurrence, incidence, and mortality of cardiovascular disease (CVD). Therefore, other, less-explored factors need to be taken in consideration when referring to CVD epidemiology.

The main goal of this clinical trial is to investigate how walking in different environments affects the psychophysiological responses to the stress of individuals with coronary artery disease (CAD) during rehabilitation. An experimental study will be carried out including individuals with CAD attending cardiac rehabilitation. The hypothesis is that psychophysiological reactions to stress in weather-sensitive (WS) individuals with CAD will differ from non-WS individuals when walking outdoors (in a natural environment).

To achieve the main goal, the following specific tasks will be implemented:

1. To determine how walking in a natural environment affects the psychophysiological reactions to stress in individuals with CAD.
2. To determine how walking in the gym affects the psychophysiological reactions to stress in individuals with CAD.
3. To analyse the associations between the psychophysiological reactions to stress of individuals with CAD and the walking environment, considering the sensitivity to the weather.
4. To determine the connections between mental flexibility and weather sensitivity.

The participants will be randomly assigned to either walking outdoors (OUT) or walking indoors (IN) groups. OUT group will walk in natural environment (in the park) along a pre-designated route. IN group will walk in a gym on a treadmill. The order and sequence of measurements within each trial will be the same. During both interventions, the participants will be supervised by investigators.

The idea is to increase knowledge about the impact of the natural environment on well-being and health and to provide more information to health professionals and the public. Awareness about the potential influence of weather sensitivity on the psychophysiological reactions to stress in patients with CAD disease may contribute to the planning and implementation of actions leading to improved medical care services and preventative measures that help to avoid the worsening of health and well-being in the future. Protective measures should be directed towards susceptible groups rather than the population. The outcomes of this experiment may have direct clinical applications for the use of different types of environments in cardiac rehabilitation.

PARALLEL

After baseline measurements, the patients will be randomly assigned to either walking outdoors (OUT) or walking indoors (IN) groups. OUT group will walk in the parke. IN group will walk in a gym on a treadmill. During both interventions, the patient will be supervised by researchers. The order and sequence of measurements within each trial will be the same.
