YE_FITNSS

This study aimed to investigate determinants of adolescent exercise behavior in a sample of healthy twins and their siblings. Body composition was measured, as well as physical fitness (standing jump, hand grip, sit-and reach flexibility, balance tests). Impulsiveness of the subjects was assessed by the delay discounting questionnaire. Regular voluntary exercise behavior was measured by a short lifestyle interview. While being equipped with a VU-AMS and Cosmed device, the subjects performed two submaximal exercise tests and one maximal exercise test. The VU University Ambulatory Monitoring System (VU-AMS) device records electrocardiogram (ECG) data and impedance cardiogram (ICG) data. The Cosmed device measures oxygen consumption (VO2) and carbon dioxide production (VCO2). VO2max (endurance capacity) was derived during the maximal exercise test. Before, during and after the exercise tests, subjects filled out the Activation-Deactivation Adjective Checklist (AD ACL), Feeling Scale (FS) and the Borg’s Rating of Perceived Exertion (RPE) at multiple time points. These questionnaires determined the subjects’ affective response to exercise. To determine zygosity, DNA was collected through buccal swabs.
