Pain Discomfort Enjoyment Levels During Moderate Exercise

Relationships of Pain, Discomfort and Enjoyment During Exercise to Weight Status and Diet Quality.

In order to better understand how pre-existing pain and also discomfort/enjoyment during exercise may influence physical activity and be related to body weight the investigators are seeking to examine these as they relate to overweight/obesity compared to normal weight individuals. Ultimately, the investigators think that people with obesity may have more and be more sensitive to pain and have lower discomfort tolerance that may lead them to experience exercise more negatively. In the real world, this could result in them stopping exercise sooner or avoiding exercise all together. Therefore it is important for the investigators to begin to understand this issue better. In addition, some preliminary studies in animals suggest that the quality of the diet may influence pain sensitivity. This has yet to be examined in humans. As such the investigators will examine whether self-reported diet quality and also some markers in participants' blood that can tell the investigators about the recent quality of a person's diet, are related to the measures of pain, enjoyment and discomfort during exercise.
