Perception of Physical Exertion in Healthy Weight and Obese Adolescents

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

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.

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

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
Physical activity intention	Subjects will be asked how much physical activity they plan or intend to participate in for the next 7 days.	7 days
Physical activity behavior	Subjects will be asked how much physical activity they participated in for the past 7 days.	7 days
