Perception of Exercise Difficulty, Physiological Response to Exercise
Conditions
Brief summary
Little is known regarding the relationship between perceived and physiological exertion in adolescents. The purpose of this study is to investigate the association between physiological and perceptual markers of effort during exercise and the relationship of these markers to other health-related behaviors in healthy weight and obese adolescents.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Physiological responses to submaximal and maximal treadmill exercise | 7-10 days | Physiological responses to submaximal and maximal treadmill exercise will be assessed during the exercise test and immediately upon completion of the exercise test. The submaximal treadmill exercise will take place at visit 1 and the maximal treadmill exercise test will take place at the 2nd and final visit which will occur 7-10 days from the 1st visit. There is no intervention between visits. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Perceptual responses to submaximal and maximal treadmill exercise | 7-10 days | Perceptual responses to submaximal and maximal treadmill exercise will be assessed during the exercise test and immediately upon completion of the exercise test. The submaximal treadmill exercise will take place at visit 1 and the maximal treadmill exercise test will take place at the 2nd and final visit which will occur 7-10 days from the 1st visit. There is no intervention between visits. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Physical activity intention | 7 days | Subjects will be asked how much physical activity they plan or intend to participate in for the next 7 days. |
| Physical activity behavior | 7 days | Subjects will be asked how much physical activity they participated in for the past 7 days. |
