Perception of Physical Exertion in Healthy Weight and Obese Adolescents

Study Overview
=================
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.

Official Title
-----------------
Perception of Physical Exertion in Healthy Weight and Obese Adolescents: A Pilot Study

Conditions
-----------------
Physiological Response to Exercise, Perception of Exercise Difficulty

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: Healthy weight (>5th-85th BMI percentile) or obese (>95th BMI percentile) male and female adolescents, 13-18 years Approval to participate in a submaximal and maximal treadmill test received from the adolescent's pediatrician. Exclusion Criteria: Underweight (<5th BMI percentile) overweight (85 - <95th BMI percentile) evidence/reporting of significant cardiovascular disease, cardiac arrhythmias, liver disease, or the chronic use of medications including diuretics, steroids and adrenergic-stimulating agents. Adolescents with emotional problems such as clinical depression or other diagnosed psychological condition and currently use prescription medication for psychological conditions. Approval to participate in a submaximal and maximal treadmill test from the adolescent's pediatrician not obtained

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Physiological responses to submaximal and maximal treadmill exercise | 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. | 7-10 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Perceptual responses to submaximal and maximal treadmill exercise | 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. | 7-10 days |
